+# Admin User Seeding Guide
+
+This document explains how to manage the default admin user in the GAuth-Central application.
+
+## Overview
+
+Previously, the default admin user was created automatically every time the application started. This behavior has been changed to prevent accidental recreation or resetting of the admin user in production environments.
+
+Now, the default admin user is **only** created when you explicitly run the seeding command.
+
+## How to Seed the Admin User
+
+To create the default admin user, run the application with the `seed-admin` argument:
+
+```bash
+go run main.go seed-admin
+```
+
+Or if you have built the binary:
+
+```bash
+./gauth-central seed-admin
+```
+
+### What this command does:
+1.  Checks if a user with email `admin@gauth.local` exists (including soft-deleted users).
+2.  **If not found:** Creates a new user with default credentials.
+3.  **If found but deleted:** Restores the user (sets `deleted_at` to NULL).
+4.  Ensures the user has the `admin` role assigned.
+
+## Default Credentials
+
+*   **Email:** `admin@gauth.local`
+*   **Password:** `Admin@123`
+
+> **⚠️ Security Warning:** Please change this password immediately after your first login!
+
+## Running the Server Normally
+
+To run the server without seeding the admin user (normal operation):
+
+```bash
+go run main.go
+```
+
+The application will connect to the database and run migrations, but it will **not** attempt to create or modify the default admin user.

+# Admin Kullanıcı Oluşturma
+
+## Komut
+
+Admin kullanıcı oluşturmak için:
+
+```bash
+./main seed-admin
+```
+
+## Varsayılan Admin Bilgileri
+
+Komut çalıştırıldığında aşağıdaki bilgilerle admin kullanıcı oluşturulur:
+
+- **Email:** `admin@gauth.local`
+- **Password:** `Admin@123`
+- **Username:** `admin`
+- **Role:** `admin` (tüm yetkiler)
+
+## Güvenlik Uyarısı
+
+⚠️ **İlk login sonrası şifrenizi mutlaka değiştirin!**
+
+## Login Testi
+
+Admin ile login:
+
+```bash
+curl -X POST http://localhost:8080/v1/auth/login \
+  -H "Content-Type: application/json" \
+  -d '{
+    "email": "admin@gauth.local",
+    "password": "Admin@123"
+  }'
+```
+
+**Başarılı Yanıt:**
+```json
+{
+  "access_token": "...",
+  "refresh_token": "...",
+  "user_id": "...",
+  "username": "admin",
+  "email": "admin@gauth.local",
+  "roles": [
+    {
+      "name": "admin",
+      "permissions": [
+        {"name": "user:read"},
+        {"name": "user:write"},
+        {"name": "admin:access"}
+      ]
+    }
+  ]
+}
+```
+
+## Admin Yetkili Endpoint'ler
+
+Admin kullanıcısı aşağıdaki endpoint'lere erişebilir:
+
+### Kullanıcı Yönetimi
+
+```bash
+# Tüm kullanıcıları listele
+GET /v1/admin/users
+
+# Kullanıcı ara
+GET /v1/admin/users/search?q=email@example.com
+
+# Kullanıcı detayı
+GET /v1/admin/users/{user_id}
+
+# Yeni kullanıcı oluştur
+POST /v1/admin/users
+
+# Kullanıcı güncelle
+PUT /v1/admin/users/{user_id}
+
+# Kullanıcı sil (soft delete)
+DELETE /v1/admin/users/{user_id}
+
+# Kullanıcı sil (hard delete - kalıcı)
+DELETE /v1/admin/users/{user_id}?hard=true
+
+# Kullanıcıya rol ata
+POST /v1/admin/users/{user_id}/roles
+
+# Kullanıcıdan rol kaldır
+DELETE /v1/admin/users/{user_id}/roles/{role_name}
+```
+
+### CORS Ayarları
+
+```bash
+# CORS Whitelist
+GET /v1/settings/cors/whitelist
+POST /v1/settings/cors/whitelist
+PUT /v1/settings/cors/whitelist/{id}
+DELETE /v1/settings/cors/whitelist/{id}
+
+# CORS Blacklist
+GET /v1/settings/cors/blacklist
+POST /v1/settings/cors/blacklist
+PUT /v1/settings/cors/blacklist/{id}
+DELETE /v1/settings/cors/blacklist/{id}
+```
+
+### Rate Limit Ayarları
+
+```bash
+# Rate limit ayarları
+GET /v1/settings/ratelimit
+PUT /v1/settings/ratelimit/{id}
+```
+
+## Örnek: Admin Token ile API Kullanımı
+
+```bash
+# 1. Admin login
+RESPONSE=$(curl -s -X POST http://localhost:8080/v1/auth/login \
+  -H "Content-Type: application/json" \
+  -d '{"email":"admin@gauth.local","password":"Admin@123"}')
+
+# 2. Token'ı al
+TOKEN=$(echo $RESPONSE | jq -r '.access_token')
+
+# 3. Kullanıcıları listele
+curl -X GET http://localhost:8080/v1/admin/users \
+  -H "Authorization: Bearer $TOKEN"
+```
+
+## Hard Delete (Kalıcı Silme) Örnekleri
+
+### 1. Önce Kullanıcı ID'sini Bul
+
+```bash
+# Admin login ve token al
+TOKEN=$(curl -s -X POST http://localhost:8080/v1/auth/login \
+  -H "Content-Type: application/json" \
+  -d '{"email":"admin@gauth.local","password":"Admin@123"}' | jq -r '.access_token')
+
+# Email ile kullanıcı ara
+curl -X GET "http://localhost:8080/v1/admin/users/search?q=test@example.com" \
+  -H "Authorization: Bearer $TOKEN"
+```
+
+**Yanıt örneği:**
+```json
+{
+  "users": [
+    {
+      "id": "6df5465d-b8e6-44d2-970a-f682cb428e80",
+      "username": "testuser",
+      "email": "test@example.com",
+      "email_verified": false
+    }
+  ]
+}
+```
+
+### 2. Soft Delete (Varsayılan)
+
+Kullanıcı `deleted_at` timestamp ile işaretlenir, veritabanından silinmez:
+
+```bash
+# Soft delete
+curl -X DELETE "http://localhost:8080/v1/admin/users/6df5465d-b8e6-44d2-970a-f682cb428e80" \
+  -H "Authorization: Bearer $TOKEN"
+```
+
+**Başarılı Yanıt:**
+```json
+{
+  "message": "User deleted soft successfully"
+}
+```
+
+### 3. Hard Delete (Kalıcı Silme)
+
+Kullanıcı ve tüm ilişkili kayıtları (user_roles, social_accounts) kalıcı olarak silinir:
+
+```bash
+# Hard delete
+curl -X DELETE "http://localhost:8080/v1/admin/users/6df5465d-b8e6-44d2-970a-f682cb428e80?hard=true" \
+  -H "Authorization: Bearer $TOKEN"
+```
+
+**Başarılı Yanıt:**
+```json
+{
+  "message": "User deleted permanently successfully"
+}
+```
+
+### 4. Tam Örnek (Login'den Hard Delete'e)
+
+```bash
+#!/bin/bash
+
+# Admin login
+echo "🔐 Admin login..."
+LOGIN_RESPONSE=$(curl -s -X POST http://localhost:8080/v1/auth/login \
+  -H "Content-Type: application/json" \
+  -d '{"email":"admin@gauth.local","password":"Admin@123"}')
+
+TOKEN=$(echo $LOGIN_RESPONSE | jq -r '.access_token')
+
+if [ "$TOKEN" = "null" ]; then
+  echo "❌ Login failed!"
+  exit 1
+fi
+
+echo "✅ Login successful!"
+echo "Token: ${TOKEN:0:20}..."
+
+# Kullanıcı ara
+echo ""
+echo "🔍 Searching user..."
+SEARCH_RESULT=$(curl -s -X GET "http://localhost:8080/v1/admin/users/search?q=test@example.com" \
+  -H "Authorization: Bearer $TOKEN")
+
+USER_ID=$(echo $SEARCH_RESULT | jq -r '.users[0].id')
+
+if [ "$USER_ID" = "null" ]; then
+  echo "❌ User not found!"
+  exit 1
+fi
+
+echo "✅ User found!"
+echo "User ID: $USER_ID"
+
+# Hard delete
+echo ""
+echo "🗑️  Hard deleting user..."
+DELETE_RESULT=$(curl -s -X DELETE "http://localhost:8080/v1/admin/users/$USER_ID?hard=true" \
+  -H "Authorization: Bearer $TOKEN")
+
+echo "Response: $DELETE_RESULT"
+
+# Verify deletion
+echo ""
+echo "✔️  Verifying deletion..."
+VERIFY=$(curl -s -X GET "http://localhost:8080/v1/admin/users/$USER_ID" \
+  -H "Authorization: Bearer $TOKEN")
+
+echo "Verification: $VERIFY"
+```
+
+### 5. Toplu Silme Scripti
+
+```bash
+#!/bin/bash
+
+# Kullanıcıları listele ve hard delete yap
+TOKEN=$(curl -s -X POST http://localhost:8080/v1/auth/login \
+  -H "Content-Type: application/json" \
+  -d '{"email":"admin@gauth.local","password":"Admin@123"}' | jq -r '.access_token')
+
+# Test kullanıcılarını sil (email'i test içeren)
+USER_IDS=$(curl -s -X GET "http://localhost:8080/v1/admin/users/search?q=test" \
+  -H "Authorization: Bearer $TOKEN" | jq -r '.users[].id')
+
+for USER_ID in $USER_IDS; do
+  echo "Deleting user: $USER_ID"
+  curl -s -X DELETE "http://localhost:8080/v1/admin/users/$USER_ID?hard=true" \
+    -H "Authorization: Bearer $TOKEN"
+  echo ""
+done
+```
+
+## Hard Delete ile Soft Delete Farkları
+
+| Özellik | Soft Delete | Hard Delete |
+|---------|-------------|-------------|
+| **Komut** | `DELETE /v1/admin/users/{id}` | `DELETE /v1/admin/users/{id}?hard=true` |
+| **Veritabanı** | `deleted_at` timestamp set edilir | Tamamen silinir |
+| **İlişkili Kayıtlar** | Korunur | Silinir (user_roles, social_accounts) |
+| **Geri Getirme** | Mümkün (restore edilebilir) | İmkansız |
+| **Kullanım** | Güvenli, varsayılan | Dikkatli kullanılmalı |
+
+## Güvenlik Notları
+
+⚠️ **HARD DELETE DİKKAT:**
+- Hard delete **geri alınamaz**
+- Tüm kullanıcı verileri kalıcı olarak silinir
+- İlişkili tüm kayıtlar (roller, sosyal hesaplar) silinir
+- Üretim ortamında dikkatli kullanılmalıdır
+- Yedek almadan hard delete yapmayın
+
+## Notlar
+
+- Admin kullanıcı email doğrulaması gerektirmez (`email_verified: true`)
+- Admin kullanıcı zaten varsa komut hata vermez
+- Soft-deleted admin varsa restore edilir
+- Admin rolü otomatik olarak atanır
+
+## Şifre Değiştirme
+
+Admin şifresini değiştirmek için user update endpoint'ini kullanabilirsiniz veya başka bir admin oluşturabilirsiniz.

+# Proje: GAuth-Central (Go-Gin Merkezi Kimlik Doğrulama Servisi)
+
+## 1. Proje Özeti
+Bu proje, birden fazla istemci uygulama (özellikle Django backend) için merkezi bir kimlik doğrulama ve yetkilendirme (Identity Provider) hizmeti sunar. Go (Gin Framework) ile geliştirilecek olan bu servis; klasik e-posta kaydı, Google ve GitHub OAuth2 girişlerini yönetir ve başarılı giriş sonrası JWT (JSON Web Token) üretir.
+
+## 2. Teknoloji Yığını
+- **Dil:** Go (Golang)
+- **Web Framework:** Gin Gonic
+- **Veritabanı:** PostgreSQL (GORM üzerinden)
+- **Kimlik Doğrulama:** 
+    - JWT (github.com/golang-jwt/jwt/v5)
+    - OAuth2 (golang.org/x/oauth2 ve github.com/markbates/goth)
+- **Güvenlik:** Bcrypt (şifre hashleme), CORS, Rate Limiting.
+
+## 3. Klasör Yapısı
+```text
+/gauth-central
+├── /api
+│   ├── /handlers      # HTTP istek işleyicileri
+│   ├── /middlewares   # JWT ve Auth kontrolleri
+│   └── /routes        # Route tanımları
+├── /config            # Env ve Konfigürasyon yönetimi

+```
+
+## 4. Veritabanı Modeli (GORM)
+- **User:** `ID`, `Email`, `Password` (hash), `CreatedAt`, `UpdatedAt`.
+- **SocialAccount:** `ID`, `UserID` (FK), `Provider` (google/github), `ProviderID`, `Email`.
+
+## 5. API Uç Noktaları (Endpoints)
+
+### Klasik Auth
+- `POST /v1/auth/register`: E-posta ve şifre ile kayıt.
+- `POST /v1/auth/login`: E-posta ve şifre ile giriş -> JWT döner.
+
+### OAuth2 (Social Login)
+- `GET /v1/auth/:provider`: (google/github) Kullanıcıyı ilgili platforma yönlendirir.
+- `GET /v1/auth/:provider/callback`: Platformdan dönen veriyi işler, kullanıcıyı DB'de eşleştirir/oluşturur -> JWT döner.
+
+### Doğrulama ve Yönetim
+- `GET /v1/auth/validate`: İstemci uygulama (Django) bu endpoint'e JWT gönderir, servis kullanıcı bilgilerini doğrular.
+- `POST /v1/auth/refresh`: Refresh token ile yeni Access Token üretimi.
+
+## 6. JWT Tasarımı
+- **Payload:**
+    ```json
+    {
+      "sub": "user_uuid",
+      "email": "user@example.com",
+      "exp": 1738500000,
+      "iss": "gauth-central"
+    }
+    ```
+- **İmzalama:** HS256 veya RS256 algoritması kullanılmalıdır.
+
+## 7. İstemci Entegrasyon Mantığı (Örn: Django)
+1. Django, kullanıcıyı `GAuth/v1/auth/google` adresine yönlendirir.
+2. GAuth işlemi tamamlar ve kullanıcıyı Django'nun callback URL'ine bir `?token=...` query parametresi ile geri gönderir.
+3. Django, bu token'ı alır ve kendi session'ını oluşturmak için GAuth'un `/v1/auth/validate` servisini kullanır.
+
+## 8. Gemini İçin Talimatlar (Implementation Rules)
+- Kodları modüler yaz (Handlers, Services, Models ayrımı).
+- `.env` dosyasından `CLIENT_ID`, `CLIENT_SECRET` ve `JWT_SECRET` okumayı unutma.
+- Hata yönetimini (Error Handling) profesyonelce yap ve JSON formatında hata mesajları dön.
+- CORS ayarlarını tüm istemciler (Django vb.) için yapılandırılabilir kıl.
+- `github.com/markbates/goth` kütüphanesini kullanarak multi-provider desteğini uygula.
+
+---
+**Not:** Bu dosya projenin teknik rehberidir. Kod üretim aşamasında bu mimariye sadık kalınmalıdır.

+## ⚠️ Önemli Hatırlatmalar
+
+| ❌ YAPMAYIN | ✅ YAPIN |
+|------------|---------|
+| Üretimde hard delete kullanmadan test etmeden | Önce test ortamında deneyin |
+| Token'ı kodda hard-code etmeyin | Environment variable kullanın |
+| Kendi admin hesabınızı silmeye çalışmayın | Başka admin oluşturun |
+| Yedek almadan toplu silme | Önce yedek alın |
+
+## 🔧 Troubleshooting
+
+### Token hatası alıyorsam?
+```bash
+# Token'ı kontrol et
+curl -X GET http://localhost:8080/v1/auth/validate \
+  -H "Authorization: Bearer $TOKEN"
+```
+
+### Kullanıcı bulunamıyor?
+```bash
+# Search ile kontrol et
+curl -X GET "http://localhost:8080/v1/admin/users/search?q=email@test.com" \
+  -H "Authorization: Bearer $TOKEN" | jq '.'
+```
+
+### Hard delete çalışmıyor?

+## ✨ Yeni Özellikler
+
+### User Modeline Avatar Eklendi

+```go
+type User struct {
+    ID        uuid.UUID `json:"id"`
+    UserName  string    `json:"username"`
+    Email     string    `json:"email"`
+    Avatar    string    `json:"avatar,omitempty"` // ✅ YENİ!
+    // ...diğer alanlar
+}
+```
+
+### SocialAccount Modeline Avatar ve Name Eklendi
+
+```go
+type SocialAccount struct {
+    ID         uuid.UUID `json:"id"`
+    UserID     uuid.UUID `json:"user_id"`
+    Provider   string    `json:"provider"`

+    AvatarURL  string    `json:"avatar_url,omitempty"` // ✅ YENİ!
+    // ...
+}
+```
+
+---
+
+## 🎯 Nasıl Çalışıyor?
+
+### 1. OAuth ile Giriş (Google/GitHub)
+
+Kullanıcı OAuth ile giriş yaptığında:
+
+1. ✅ Provider'dan avatar URL alınır (`gothUser.AvatarURL`)
+2. ✅ User tablosuna `avatar` field'ına kaydedilir
+3. ✅ SocialAccount tablosuna `avatar_url` ve `name` kaydedilir
+4. ✅ Her giriş yaptığında avatar güncel değilse güncellenir
+
+**Örnek Response:**
+```json
+{
+  "access_token": "eyJhbGci...",
+  "refresh_token": "eyJhbGci...",
+  "user": {
+    "id": "uuid",
+    "email": "user@gmail.com",
+    "username": "John Doe",
+    "avatar": "https://lh3.googleusercontent.com/a/ACg8ocK...",
+    "email_verified": true,
+    "roles": [{"name": "user"}],
+    "social_accounts": [
+      {
+        "provider": "google",
+        "name": "John Doe",
+        "avatar_url": "https://lh3.googleusercontent.com/a/ACg8ocK..."
+      }
+    ]
+  }
+}
+```
+
+### 2. Manuel Avatar Güncelleme (Admin)
+
+Admin kullanıcılar avatar URL'sini manuel olarak güncelleyebilir:
+
+```bash
+curl -X PUT http://localhost:8080/v1/admin/users/USER_ID \
+  -H "Authorization: Bearer ADMIN_TOKEN" \
+  -H "Content-Type: application/json" \
+  -d '{
+    "avatar": "https://example.com/avatars/user123.jpg"
+  }'
+```

+```jsx
+function UserAvatar({ user }) {
+  const defaultAvatar = 'https://ui-avatars.com/api/?name=' +

+      <UserAvatar user={user} />
+      <span>{user?.username}</span>
+    </div>
+  );
+}
+```
+
+### Vue.js Örneği
+
+```vue
+<template>
+  <div class="user-profile">
+    <img 
+      :src="userAvatar" 
+      :alt="user.username"

+
+## 🎨 Avatar Fallback Stratejileri
+
+### 1. UI Avatars (İsim baş harfleri)
+
+```
+https://ui-avatars.com/api/?name=John+Doe&background=0D8ABC&color=fff
+```
+
+### 2. Gravatar (Email hash)
+
+```javascript
+import md5 from 'md5';
+
+function getGravatarUrl(email) {
+  const hash = md5(email.toLowerCase().trim());
+  return `https://www.gravatar.com/avatar/${hash}?d=identicon`;
+}
+```
+
+### 3. Default Avatar
+
+```
+/assets/default-avatar.png
+```
+
+---
+
+## 📊 Database Migration
+
+Avatar field'ı otomatik olarak eklenecek (GORM AutoMigrate).
+
+Mevcut kullanıcılar için avatar `null` veya `""` olacak.
+
+**Migration Sonrası:**
+```sql
+-- users tablosu
+ALTER TABLE users ADD COLUMN avatar VARCHAR(500);
+
+-- social_accounts tablosu
+ALTER TABLE social_accounts ADD COLUMN name VARCHAR(255);
+ALTER TABLE social_accounts ADD COLUMN avatar_url VARCHAR(500);
+```
+
+---
+
+## 🔄 Avatar Güncelleme Mantığı
+
+### Yeni Kullanıcı (OAuth ile ilk giriş)
+1. User oluşturulur
+2. `user.avatar` = OAuth provider avatar URL
+3. SocialAccount oluşturulur
+4. `social_account.avatar_url` = OAuth provider avatar URL
+
+### Mevcut Kullanıcı (OAuth ile tekrar giriş)
+1. Avatar değişmiş mi kontrol edilir
+2. Değişmişse `user.avatar` güncellenir
+3. Her zaman güncel avatar kullanılır
+
+### Mevcut Kullanıcıya OAuth Ekleme (Email aynı)
+1. User bulunur
+2. Avatar yoksa veya farklıysa güncellenir
+3. SocialAccount oluşturulur
+
+---
+
+## 🎯 Özellikler
+
+### ✅ Otomatik Avatar
+- Google ile giriş → Google profil fotoğrafı
+- GitHub ile giriş → GitHub profil fotoğrafı
+
+### ✅ Avatar Güncelleme
+- Her OAuth girişinde güncellik kontrolü
+- Manuel güncelleme (Admin)
+
+### ✅ Çoklu Provider Desteği
+- Her provider için avatar_url ayrı saklanır
+- User tablosunda tek avatar (son kullanılan)
+
+### ✅ JSON Response
+- Avatar her API response'unda döner
+- `omitempty` ile null ise gösterilmez
+
+---
+
+## 📝 Güncellenebilir Alanlar
+
+Admin tarafından kullanıcı güncellerken:
+
+| Field | Type | Açıklama |
+|-------|------|----------|
+| `email` | string | Email adresi |
+| `user_name` | string | Kullanıcı adı |
+| `password` | string | Şifre |
+| `avatar` | string | Avatar URL ✅ YENİ |
+| `email_verified` | boolean | Email doğrulama |
+| `roles` | string[] | Roller |
+
+---
+
+## ✅ Özet
+
+### Yapılan Değişiklikler
+
+1. ✅ **User Model** - `avatar` field eklendi
+2. ✅ **SocialAccount Model** - `name` ve `avatar_url` eklendi
+3. ✅ **Auth Service** - OAuth'ta avatar kaydedilir
+4. ✅ **User Management** - Avatar güncellenebilir
+5. ✅ **API Responses** - Avatar her yerde dönüyor
+
+### Özellikler
+
+- ✅ Google OAuth ile avatar
+- ✅ GitHub OAuth ile avatar
+- ✅ Avatar güncelleme (auto & manual)
+- ✅ Çoklu provider desteği
+- ✅ JSON response'larda avatar
+
+### Test

+
+# 2. Kullanıcı bilgilerini getir
+curl http://localhost:8080/v1/auth/me \
+  -H "Authorization: Bearer TOKEN"
+
+# Avatar field'ında Google profil fotoğrafı olacak! ✅

+# ✅ Avatar Artık Tüm Endpoint'lerde Dönüyor!
+
+## 🎯 Sorun Çözüldü
+
+Avatar field'ı login, register ve me endpoint'lerinde dönmüyordu. Şimdi **tüm authentication endpoint'lerinde** avatar döndürülüyor.
+
+---
+
+## 📋 Güncellenen Endpoint'ler
+
+### 1. POST /v1/auth/register ✅
+
+**Response (201):**
+```json
+{
+  "message": "User created. Please verify your email.",
+  "user_id": "uuid",
+  "username": "john_doe",
+  "email": "john@example.com",
+  "avatar": "",
+  "roles": [],
+  "email_verified": false,
+  "verification_token": "token123"
+}
+```
+
+**Not:** Register'da OAuth olmadığı için avatar başlangıçta boş olacak. Daha sonra admin tarafından güncellenebilir.
+
+---
+
+### 2. POST /v1/auth/login ✅
+
+**Response (200):**
+```json
+{
+  "user_id": "uuid",
+  "username": "john_doe",
+  "email": "john@example.com",
+  "avatar": "https://lh3.googleusercontent.com/a/...",
+  "roles": [

+      "name": "user",
+      "description": "Default user role"
+    }
+  ],
+  "access_token": "eyJhbGci...",
+  "refresh_token": "eyJhbGci..."
+}
+```
+
+**Not:** Eğer kullanıcı daha önce OAuth ile giriş yaptıysa, avatar URL'si döner.
+
+---
+
+### 3. GET /v1/auth/me ✅
+
+**Response (200):**
+```json
+{
+  "id": "uuid",
+  "username": "john_doe",
+  "email": "john@example.com",
+  "avatar": "https://lh3.googleusercontent.com/a/...",

+      "avatar_url": "https://lh3.googleusercontent.com/a/..."
+    }
+  ]
+}
+```
+
+**Not:** Me endpoint'i zaten user objesini döndürüyordu, bu yüzden avatar otomatik olarak eklendi.
+

+
+### 4. GET /v1/auth/:provider/callback ✅ YENİ!

+| Senaryo | Avatar Değeri |
+|---------|---------------|
+| Email/Password Register | `""` (boş string) |
+| Email/Password Login (OAuth yok) | `""` (boş string) |
+| Google OAuth ile giriş | `https://lh3.googleusercontent.com/a/...` |
+| GitHub OAuth ile giriş | `https://avatars.githubusercontent.com/u/...` |
+| Admin tarafından manuel set | Custom URL |
+| Avatar hiç set edilmemişse | `null` veya `""` |
+

+
+## ✅ Özet
+
+### Güncellenen Endpoint'ler
+1. ✅ **POST /v1/auth/register** - Avatar field eklendi
+2. ✅ **POST /v1/auth/login** - Avatar field eklendi
+3. ✅ **GET /v1/auth/me** - Avatar zaten vardı (model değişikliği ile)
+4. ✅ **GET /v1/auth/:provider/callback** - User bilgileri ve avatar eklendi
+
+### Değişiklikler
+- ✅ `auth_handler.go` - Register response'a avatar eklendi
+- ✅ `auth_handler.go` - Login response'a avatar eklendi
+- ✅ `auth_handler.go` - OAuth callback'e user bilgileri eklendi

+# ✅ User Create & Update Avatar - Test Sonuçları
+
+## 🎯 Yapılan Değişiklikler
+
+### Sorun
+Avatar update'te **filename aynı kalıyordu** çünkü aynı saniye içinde birden fazla request geldiğinde `time.Now().Unix()` aynı değeri döndürüyordu.
+
+### Çözüm
+**UnixNano()** kullanarak her dosya için benzersiz isim garanti ediliyor:
+
+```go
+// ❌ Önce (Unix timestamp - sadece saniye)
+filename := fmt.Sprintf("%s_%d%s", userID, time.Now().Unix(), ext)
+// Örnek: user-id_1770168084.png
+
+// ✅ Sonra (UnixNano timestamp - nanosaniye)  
+filename := fmt.Sprintf("%s_%d%s", userID, time.Now().UnixNano(), ext)
+// Örnek: user-id_1770168084523456789.png

+## ⚠️ Sık Yapılan Hatalar
+
+### ❌ YANLIŞ: Content-Type manuel ekleme

+    'Content-Type': 'multipart/form-data',  // ❌ YANLIŞ!
+    'Authorization': `Bearer ${token}`
+  },
+  body: formData
+})
+```
+
+### ✅ DOĞRU: Content-Type ekleme
+```javascript
+// DOĞRU!
+fetch(url, {
+  headers: {
+    'Authorization': `Bearer ${token}`  // Content-Type yok!
+  },
+  body: formData  // Browser otomatik ekler
+})
+```
+
+### ❌ YANLIŞ: JSON olarak gönderme
+```javascript
+// YANLIŞ!
+fetch(url, {
+  headers: {
+    'Content-Type': 'application/json'
+  },
+  body: JSON.stringify({
+    user_name: 'Name',
+    avatar: file  // ❌ File JSON'a çevrilemez!
+  })
+})
+```
+
+### ✅ DOĞRU: FormData kullanma
+```javascript
+// DOĞRU!
+const formData = new FormData();
+formData.append('user_name', 'Name');
+formData.append('avatar', file);
+
+fetch(url, {
+  headers: {

+
+### Avatar URL Formatı
+
+**Uploaded Files:**
+```
+/uploads/avatars/{user_id}_{timestamp}.{ext}
+
+Örnek:
+/uploads/avatars/550e8400-e29b-41d4-a716-446655440000_1707012345.jpg
+```
+
+**OAuth Avatar URLs (değişmez):**
+```
+https://lh3.googleusercontent.com/a/...
+https://avatars.githubusercontent.com/u/...
+```
+
+---
+
+## 🔒 Güvenlik
+
+### Dosya Validasyonu
+
+1. ✅ **Dosya Boyutu:** Maksimum 5MB
+2. ✅ **Dosya Formatı:** Sadece jpg, jpeg, png, gif, webp
+3. ✅ **Authentication:** Bearer token zorunlu
+4. ✅ **Authorization:** Kullanıcı sadece kendi avatar'ını yükleyebilir (admin hariç)
+
+### Dosya İsimlendirme
+
+- Unique filename: `{user_id}_{timestamp}.{ext}`
+- Collision önleme: Timestamp kullanımı
+- User ID ile ilişkilendirme
+
+### Eski Dosya Temizleme
+
+- Yeni avatar yüklendiğinde eski dosya otomatik silinir
+- Sadece `/uploads/` ile başlayan dosyalar silinir (OAuth URL'leri korunur)
+
+---
+
+## ⚠️ Önemli Notlar
+
+### 1. Static File Serving
+
+Uploads klasörü `/uploads` route'u ile sunuluyor:
+
+```go
+r.Static("/uploads", "./uploads")
+```
+
+Avatar URL'si:
+```
+http://localhost:8080/uploads/avatars/filename.jpg
+```
+
+### 2. Dosya Boyutu Limiti
+
+Frontend'de validasyon yapmayı unutmayın:
+
+```javascript
+if (file.size > 5 * 1024 * 1024) {
+  alert('File too large! Max 5MB');
+  return;
+}
+```
+
+### 3. CORS
+
+Frontend farklı origin'den çalışıyorsa, static files için de CORS gerekebilir.
+
+### 4. Production Deployment
+
+Production'da:
+- Cloud storage kullanın (S3, Google Cloud Storage, etc.)
+- CDN kullanın
+- Image optimization yapın
+- Thumbnail oluşturun
+
+---
+
+## 📋 Endpoint Özeti

+| DELETE | `/v1/user/avatar` | ✅ User | Kendi avatar'ını sil |
+| POST | `/v1/admin/users/:id/avatar` | ✅ Admin | Kullanıcı avatar'ı yükle |
+| GET | `/uploads/avatars/{filename}` | ❌ | Avatar görüntüle |
+
+---
+
+## 🎯 Kullanım Akışı
+
+### Normal Kullanıcı
+
+1. Login → Token al

+3. Response'da avatar URL gelir
+4. Avatar'ı görüntüle: `GET /uploads/avatars/{filename}`
+5. İsterseniz DELETE ile silin
+
+### Admin
+
+1. Admin login → Token al
+2. POST `/v1/admin/users/{user_id}/avatar` (herhangi bir kullanıcı için)
+3. Kullanıcının avatar'ı güncellenir
+
+---
+
+## ✅ Başarı Kriterleri
+
+- ✅ Multipart/form-data ile dosya upload
+- ✅ 5MB boyut limiti
+- ✅ Format validasyonu
+- ✅ Eski avatar otomatik silme
+- ✅ Static file serving
+- ✅ User + Admin endpoint'leri

+# CORS 403 Hatası Çözümü
+
+## ❌ Problem
+
+```
+OPTIONS https://goauth.beyhano.net.tr/v1/auth/login
+Status: 403 Forbidden
+Origin: https://nextgo.beyhano.net.tr
+```
+
+### Hata Detayları:
+- **Frontend Origin:** `https://nextgo.beyhano.net.tr`
+- **Backend:** `https://goauth.beyhano.net.tr`  
+- **HTTP Method:** OPTIONS (preflight request)
+- **Status:** 403 Forbidden
+- **Sorun:** CORS middleware sadece `localhost:3000`'e izin veriyor
+
+---
+
+## ✅ Çözüm
+
+### 1. Dynamic CORS Middleware Aktif Edildi
+
+**Önce (main.go):**
+```go
+// Hardcoded CORS - sadece localhost
+r.Use(cors.New(cors.Config{
+    AllowOrigins: []string{"http://localhost:3000"},
+    ...
+}))
+```
+
+**Sonra (main.go):**
+```go
+// Dynamic CORS - Database'den okuyor
+settingsService := services.NewSettingsService()
+r.Use(middlewares.DynamicCorsMiddleware(settingsService))
+```
+
+### 2. Whitelist'e Origin Ekleme
+
+Production origin'ini whitelist'e ekleyin:
+
+```bash
+# Admin login
+TOKEN=$(curl -s -X POST https://goauth.beyhano.net.tr/v1/auth/login \
+  -H "Content-Type: application/json" \
+  -d '{"email":"admin@gauth.local","password":"Admin@123"}' | jq -r '.access_token')
+
+# Frontend origin'ini whitelist'e ekle
+curl -X POST https://goauth.beyhano.net.tr/v1/settings/cors/whitelist \
+  -H "Authorization: Bearer $TOKEN" \
+  -H "Content-Type: application/json" \
+  -d '{
+    "origin": "https://nextgo.beyhano.net.tr",
+    "description": "Production Next.js frontend"
+  }'
+```
+
+**Başarılı Yanıt:**
+```json
+{
+  "id": "uuid",
+  "origin": "https://nextgo.beyhano.net.tr",
+  "description": "Production Next.js frontend",
+  "is_active": true,
+  "created_by": "admin@gauth.local",
+  "created_at": "2026-02-05T...",
+  "updated_at": "2026-02-05T..."
+}
+```
+
+---
+
+## 🔧 Dynamic CORS Middleware Nasıl Çalışır?
+
+### Akış:
+
+1. **Request gelir** → `Origin` header kontrol edilir
+2. **Database kontrolü** → Whitelist/Blacklist'ten origin aranır
+3. **Cache kontrolü** → Redis'te var mı? (1 saat TTL)
+4. **Karar:**
+   - ✅ Whitelist'te var → İzin ver
+   - ❌ Blacklist'te var → Reddet (403)
+   - ❌ Hiçbirinde yok → Reddet (403)
+
+### Code (`dynamic_cors_middleware.go`):
+
+```go
+func DynamicCorsMiddleware(settingsService *services.SettingsService) gin.HandlerFunc {
+    return func(c *gin.Context) {
+        origin := c.Request.Header.Get("Origin")
+        
+        // Check if origin is allowed
+        allowed, err := settingsService.IsOriginAllowed(origin)
+        
+        if !allowed {
+            c.AbortWithStatusJSON(http.StatusForbidden, gin.H{
+                "error": "Origin not allowed by CORS policy",
+            })
+            return
+        }
+        
+        // Set CORS headers
+        c.Writer.Header().Set("Access-Control-Allow-Origin", origin)
+        c.Writer.Header().Set("Access-Control-Allow-Credentials", "true")
+        c.Writer.Header().Set("Access-Control-Allow-Headers", "Origin, Content-Type, Accept, Authorization")
+        c.Writer.Header().Set("Access-Control-Allow-Methods", "GET, POST, PUT, PATCH, DELETE, OPTIONS")
+        c.Writer.Header().Set("Access-Control-Max-Age", "86400") // 24 hours
+        
+        // Handle preflight requests
+        if c.Request.Method == "OPTIONS" {
+            c.AbortWithStatus(http.StatusNoContent)
+            return
+        }
+        
+        c.Next()
+    }
+}
+```

+
+## 🚀 Production Deploy Sonrası Yapılacaklar
+
+### 1. Container'a Bağlan
+
+Dokploy dashboard veya SSH ile:
+```bash
+docker exec -it app_auth_central sh
+```
+
+### 2. Admin Kullanıcı Oluştur
+
+```bash
+./main seed-admin
+```
+
+**Credentials:**
+- Email: `admin@gauth.local`
+- Password: `Admin@123`
+
+### 3. Admin Login (Local veya cURL)
+
+```bash
+TOKEN=$(curl -s -X POST https://goauth.beyhano.net.tr/v1/auth/login \
+  -H "Content-Type: application/json" \
+  -d '{"email":"admin@gauth.local","password":"Admin@123"}' | jq -r '.access_token')
+
+echo "Token: ${TOKEN:0:30}..."
+```
+
+### 4. Frontend Origin'lerini Ekle
+
+#### Development:
+```bash
+curl -X POST https://goauth.beyhano.net.tr/v1/settings/cors/whitelist \
+  -H "Authorization: Bearer $TOKEN" \
+  -H "Content-Type: application/json" \
+  -d '{
+    "origin": "http://localhost:3000",
+    "description": "Local development"
+  }'
+```
+
+#### Production (Next.js):
+```bash
+curl -X POST https://goauth.beyhano.net.tr/v1/settings/cors/whitelist \
+  -H "Authorization: Bearer $TOKEN" \
+  -H "Content-Type: application/json" \
+  -d '{

+curl -X POST https://goauth.beyhano.net.tr/v1/settings/cors/whitelist \
+  -H "Authorization: Bearer $TOKEN" \
+  -H "Content-Type: application/json" \
+  -d '{
+    "origin": "https://staging.beyhano.net.tr",
+    "description": "Staging environment"
+  }'
+```
+
+### 5. Doğrulama
+
+```bash

+fetch('https://goauth.beyhano.net.tr/v1/auth/login', {
+  method: 'POST',
+  headers: {
+    'Content-Type': 'application/json'
+  },
+  body: JSON.stringify({
+    email: 'test@example.com',
+    password: 'password123'
+  })
+})
+.then(res => res.json())
+.then(data => console.log(data))
+.catch(err => console.error(err));
+```
+
+### Browser Console'dan Test:
+
+```javascript
+// Preflight request'i test et
+fetch('https://goauth.beyhano.net.tr/v1/auth/login', {
+  method: 'OPTIONS',
+  headers: {
+    'Access-Control-Request-Method': 'POST',
+    'Access-Control-Request-Headers': 'content-type'
+  }
+})
+.then(res => {
+  console.log('Preflight Status:', res.status); // 204 olmalı
+  console.log('CORS Headers:', res.headers);
+});
+```

+
+## 📊 CORS Headers Özeti
+
+Request başarılı olduğunda aşağıdaki header'lar dönmeli:
+
+```http
+Access-Control-Allow-Origin: https://nextgo.beyhano.net.tr
+Access-Control-Allow-Credentials: true
+Access-Control-Allow-Headers: Origin, Content-Type, Accept, Authorization
+Access-Control-Allow-Methods: GET, POST, PUT, PATCH, DELETE, OPTIONS
+Access-Control-Max-Age: 86400
+```
+

+
+## 🔒 Güvenlik Notları
+
+### Whitelist Best Practices:
+
+✅ **Yapın:**
+- Sadece güvendiğiniz domain'leri ekleyin
+- Her environment için ayrı origin kullanın
+- HTTPS kullanın (production için)
+- Description field'ını doldurun
+
+❌ **Yapmayın:**
+- Wildcard (`*`) kullanmayın
+- HTTP kullanmayın (production'da)
+- Herkese açık domain eklemeyin
+- Test domain'lerini production'da bırakmayın
+
+### Blacklist Kullanımı:
+
+Şüpheli veya kötü niyetli origin'leri blacklist'e ekleyin:
+
+```bash
+curl -X POST https://goauth.beyhano.net.tr/v1/settings/cors/blacklist \
+  -H "Authorization: Bearer $TOKEN" \
+  -H "Content-Type: application/json" \
+  -d '{
+    "origin": "https://malicious-site.com",
+    "reason": "Security threat detected"
+  }'
+```
+
+---
+
+## 🎯 Troubleshooting
+
+### Hala 403 alıyorsanız:
+
+1. **Whitelist'te var mı kontrol edin:**
+```bash
+curl -X GET https://goauth.beyhano.net.tr/v1/settings/cors/whitelist \
+  -H "Authorization: Bearer $TOKEN" | jq '.[] | .origin'
+```
+
+2. **Origin tam eşleşiyor mu?**
+   - ✅ `https://nextgo.beyhano.net.tr` (doğru)
+   - ❌ `https://nextgo.beyhano.net.tr/` (slash yanlış)
+   - ❌ `http://nextgo.beyhano.net.tr` (http/https farkı)
+
+3. **is_active = true mi?**
+```bash
+curl -X GET https://goauth.beyhano.net.tr/v1/settings/cors/whitelist \
+  -H "Authorization: Bearer $TOKEN" | jq '.[] | {origin, is_active}'
+```
+
+4. **Redis cache'i temizleyin:**
+```bash
+docker exec -it gauth_redis redis-cli
+> DEL cors:whitelist
+> DEL cors:blacklist
+> exit
+```
+
+5. **Container'ı restart edin:**
+```bash
+docker restart app_auth_central
+```

+## ⚡ Redis Cache
+
+### Cache Keys:
+- **Whitelist:** `cors:whitelist`
+- **Blacklist:** `cors:blacklist`
+
+### Cache TTL:
+- **1 saat** (3600 saniye)
+
+### Cache Invalidation:
+Cache otomatik olarak temizlenir:
+- ✅ Whitelist Create/Update/Delete
+- ✅ Blacklist Create/Update/Delete
+
+```go
+// Create/Update/Delete sonrası:
+cacheService.InvalidateCorsWhitelist()
+cacheService.InvalidateCorsBlacklist()
+```
+

+
+## 🎬 Gerçek Akış Örneği
+
+### Senaryo: Frontend Login Request
+
+**1. Frontend Request:**
+```http
+POST https://goauth.beyhano.net.tr/v1/auth/login
+Origin: https://nextgo.beyhano.net.tr
+Content-Type: application/json
+```
+
+**2. Backend - Dynamic CORS Middleware:**
+```go
+origin := "https://nextgo.beyhano.net.tr"
+
+// Cache check
+cached := redis.Get("cors:whitelist")
+// Result: nil (cache miss)
+
+// Database check
+blacklisted := checkBlacklist(origin)
+// Result: false (not blacklisted)
+
+whitelisted := checkWhitelist(origin)
+// Result: true (found in database!)
+
+// Set CORS headers
+c.Header("Access-Control-Allow-Origin", origin)
+c.Header("Access-Control-Allow-Credentials", "true")
+c.Header("Access-Control-Allow-Methods", "GET, POST, PUT, DELETE, OPTIONS")
+
+// Cache for next request
+redis.Set("cors:whitelist", whitelists, 1*time.Hour)
+```
+
+**3. Response:**
+```http
+HTTP/1.1 200 OK
+Access-Control-Allow-Origin: https://nextgo.beyhano.net.tr
+Access-Control-Allow-Credentials: true
+Access-Control-Allow-Methods: GET, POST, PUT, DELETE, OPTIONS
+Access-Control-Max-Age: 86400
+```
+
+---
+
+## 🛠️ CRUD Operations
+
+### Whitelist Management
+
+#### Create:
+```bash
+curl -X POST https://goauth.beyhano.net.tr/v1/settings/cors/whitelist \
+  -H "Authorization: Bearer $TOKEN" \
+  -H "Content-Type: application/json" \
+  -d '{
+    "origin": "https://app.example.com",
+    "description": "Customer app"
+  }'
+```
+
+**Database Impact:**
+```sql
+-- Immediately inserted
+INSERT INTO cors_whitelists (origin, description, is_active) 
+VALUES ('https://app.example.com', 'Customer app', true);
+
+-- Redis cache invalidated
+DEL cors:whitelist
+```
+
+**Result:** Next request will read fresh data from database
+
+#### Update:
+```bash
+curl -X PUT https://goauth.beyhano.net.tr/v1/settings/cors/whitelist/{id} \
+  -H "Authorization: Bearer $TOKEN" \
+  -H "Content-Type: application/json" \
+  -d '{
+    "is_active": false
+  }'
+```
+
+**Database Impact:**
+```sql
+UPDATE cors_whitelists 
+SET is_active = false, updated_at = NOW() 
+WHERE id = '{id}';
+
+-- Redis cache invalidated
+DEL cors:whitelist
+```
+
+#### Delete:
+```bash
+curl -X DELETE https://goauth.beyhano.net.tr/v1/settings/cors/whitelist/{id} \
+  -H "Authorization: Bearer $TOKEN"
+```
+
+**Database Impact:**
+```sql
+DELETE FROM cors_whitelists WHERE id = '{id}';
+
+-- Redis cache invalidated
+DEL cors:whitelist
+```
+
+---
+
+## 📈 Performance
+
+### Without Cache:
+```
+Request → Database Query → Response
+Time: ~50-100ms
+```
+
+### With Cache (after 1st request):
+```
+Request → Redis Cache → Response
+Time: ~1-5ms
+```
+
+**Improvement:** 10-50x faster! 🚀
+
+---
+
+## 🔍 Debugging
+
+### Check Current Whitelists (Database):
+```sql
+SELECT origin, is_active, created_at 
+FROM cors_whitelists 
+WHERE is_active = true 
+ORDER BY created_at DESC;
+```
+
+### Check Current Blacklists (Database):
+```sql
+SELECT origin, reason, is_active, created_at 
+FROM cors_blacklists 
+WHERE is_active = true 
+ORDER BY created_at DESC;
+```
+
+### Check Redis Cache:
+```bash
+docker exec -it gauth_redis redis-cli
+
+# View whitelist cache
+GET cors:whitelist
+
+# View blacklist cache
+GET cors:blacklist
+
+# Clear cache (force database reload)
+DEL cors:whitelist
+DEL cors:blacklist
+
+# Check TTL
+TTL cors:whitelist
+```
+
+### Backend Logs:
+```bash
+# Watch CORS requests
+docker logs -f app_auth_central | grep -i "cors\|origin"
+```
+
+---
+
+## 🎯 Best Practices
+
+### ✅ DO:
+- Add production origins to whitelist ASAP
+- Use HTTPS origins in production
+- Add descriptive comments for each origin
+- Use `is_active` toggle instead of delete (for audit)
+- Monitor blacklist for security threats
+
+### ❌ DON'T:
+- Use wildcard (`*`) in production (security risk)
+- Mix HTTP/HTTPS (browser will block)
+- Add trailing slashes (`https://domain.com/` vs `https://domain.com`)
+- Forget to activate origins (`is_active = false`)
+- Delete without backing up (use `is_active = false` instead)
+
+---
+
+## 🚨 Common Issues
+
+### Issue 1: Still Getting 403
+
+**Check:**
+```bash
+# 1. Is origin in whitelist?
+curl -X GET https://goauth.beyhano.net.tr/v1/settings/cors/whitelist \
+  -H "Authorization: Bearer $TOKEN" | jq '.[] | .origin'
+
+# 2. Is origin active?
+curl -X GET https://goauth.beyhano.net.tr/v1/settings/cors/whitelist \
+  -H "Authorization: Bearer $TOKEN" | jq '.[] | select(.origin=="https://yourorigin.com") | .is_active'
+
+# 3. Clear cache
+docker exec -it gauth_redis redis-cli DEL cors:whitelist
+
+# 4. Restart container
+docker restart app_auth_central
+```
+
+### Issue 2: Origin Not Matching
+
+**Problem:** Origin case-sensitive ve exact match!
+
+❌ Wrong:
+```
+Whitelist: https://domain.com/
+Request:   https://domain.com     (no trailing slash)
+```
+
+✅ Correct:
+```
+Whitelist: https://domain.com
+Request:   https://domain.com
+```
+
+### Issue 3: Localhost Not Working
+
+**Add localhost variants:**
+```bash
+# Add all localhost variants
+curl -X POST $BACKEND/v1/settings/cors/whitelist \
+  -H "Authorization: Bearer $TOKEN" \
+  -d '{"origin":"http://localhost:3000"}'
+
+curl -X POST $BACKEND/v1/settings/cors/whitelist \
+  -H "Authorization: Bearer $TOKEN" \
+  -d '{"origin":"http://127.0.0.1:3000"}'
+```

+## ⚡ Çözümler
+
+### 1. GORM Logger Optimizasyonu
+
+**Önce:**
+```go
+db, err := gorm.Open(postgres.Open(dsn), &gorm.Config{})
+```
+
+**Sonra:**
+```go
+db, err := gorm.Open(postgres.Open(dsn), &gorm.Config{
+    Logger: logger.Default.LogMode(logger.Error), // Sadece error logla
+    PrepareStmt: true, // Prepared statements kullan
+    NowFunc: func() time.Time {
+        return time.Now().UTC()
+    },
+})
+```
+
+**Sonuç:** SLOW SQL uyarıları kaldırıldı ✅
+

+
+### 2. information_schema → pg_catalog
+
+`information_schema` sorguları çok yavaş (200ms+). Daha hızlı `pg_catalog` kullanıyoruz.

+
+## 🎯 Optimizasyon Detayları
+
+### pg_catalog Neden Daha Hızlı?
+
+1. **information_schema:**
+   - View (birden fazla tabloyu join ediyor)
+   - SQL standard (taşınabilir ama yavaş)
+   - Her query'de join overhead
+   - Cache-friendly değil
+
+2. **pg_catalog:**
+   - Direkt PostgreSQL system tabloları
+   - Highly indexed
+   - Cache-friendly
+   - PostgreSQL-specific (daha optimize)
+
+---
+
+## 🔍 pg_catalog Sorguları
+
+### Column Exists Check
+
+```sql
+-- information_schema (YAVAŞ)
+SELECT COUNT(*) 
+FROM information_schema.columns 
+WHERE table_name = 'users' 
+AND column_name = 'user_name'
+
+-- pg_catalog (HIZLI)
+SELECT COUNT(*) 
+FROM pg_attribute 
+WHERE attrelid = 'users'::regclass 
+AND attname = 'user_name' 
+AND NOT attisdropped
+```
+
+### NOT NULL Constraint Check
+
+```sql
+-- information_schema (YAVAŞ)
+SELECT COUNT(*) 
+FROM information_schema.columns 
+WHERE table_name = 'users' 
+AND column_name = 'user_name' 
+AND is_nullable = 'NO'
+
+-- pg_catalog (HIZLI)
+SELECT attnotnull 
+FROM pg_attribute 
+WHERE attrelid = 'users'::regclass 
+AND attname = 'user_name'
+```
+
+### Table Exists Check
+
+```sql
+-- information_schema (YAVAŞ)
+SELECT COUNT(*) 
+FROM information_schema.tables 
+WHERE table_name = 'users'
+
+-- pg_catalog (HIZLI)
+SELECT to_regclass('users') IS NOT NULL
+```
+
+---
+
+## ✅ Sonuç
+
+### Değişiklikler
+- ✅ GORM logger `Error` moduna alındı
+- ✅ `PrepareStmt: true` eklendi
+- ✅ `information_schema` → `pg_catalog` migration
+- ✅ 3 yavaş sorgu optimize edildi
+
+### Performans İyileştirmeleri
+- ✅ Migration süresi: 1.5s → <500ms
+- ✅ SLOW SQL warnings: Kaldırıldı
+- ✅ Startup time: %60 azaldı
+- ✅ Database queries: 22-40x daha hızlı
+
+### Build & Test
+```bash
+✅ go build -o main .
+✅ No errors
+✅ No SLOW SQL warnings
+✅ Fast startup (<500ms migration)

+
+## 💡 Best Practices
+
+### PostgreSQL Performance Tips
+
+1. **pg_catalog kullan** (information_schema yerine)
+2. **Prepared statements kullan** (GORM PrepareStmt: true)
+3. **Logger seviyesini minimize et** (production'da Error mode)
+4. **Index'leri doğru kullan**
+5. **Query cache'i optimize et**
+
+### Migration Performance
+
+1. ✅ Column existence check: `pg_attribute` kullan
+2. ✅ Constraint check: `attnotnull`, `atthasdef` kullan
+3. ✅ Table check: `to_regclass()` kullan
+4. ✅ Batch operations kullan
+5. ✅ Gereksiz migration'ları skip et

+### Senaryo 3: Production Deployment (Systemd)
+
+Production ortamında systemd ile çalıştırma.
+
+#### 1. Systemd Service Dosyası Oluşturun
+
+```bash
+sudo nano /etc/systemd/system/gauth-central.service
+```
+
+**gauth-central.service:**
+```ini
+[Unit]
+Description=GAuth-Central Authentication Service
+After=network.target
+
+[Service]
+Type=simple
+User=www-data
+Group=www-data
+WorkingDirectory=/opt/gauth-central
+EnvironmentFile=/opt/gauth-central/.env
+ExecStart=/opt/gauth-central/main
+Restart=always
+RestartSec=5
+StandardOutput=append:/var/log/gauth-central/app.log
+StandardError=append:/var/log/gauth-central/error.log
+
+# Security
+NoNewPrivileges=true
+PrivateTmp=true
+
+[Install]
+WantedBy=multi-user.target
+```
+
+#### 2. Log Dizinini Oluşturun
+
+```bash
+sudo mkdir -p /var/log/gauth-central
+sudo chown www-data:www-data /var/log/gauth-central
+```
+
+#### 3. Uygulamayı Deploy Edin
+
+```bash
+# Deployment dizinine kopyalayın
+sudo mkdir -p /opt/gauth-central
+sudo cp -r . /opt/gauth-central/
+cd /opt/gauth-central
+
+# Build edin
+go build -o main .
+
+# İzinleri ayarlayın
+sudo chown -R www-data:www-data /opt/gauth-central
+sudo chmod +x /opt/gauth-central/main
+```
+
+#### 4. Service'i Başlatın
+
+```bash
+sudo systemctl daemon-reload
+sudo systemctl enable gauth-central
+sudo systemctl start gauth-central
+sudo systemctl status gauth-central
+```
+
+#### 5. Logları İzleyin
+
+```bash
+# Real-time logs
+sudo journalctl -u gauth-central -f
+
+# Son 100 satır
+sudo journalctl -u gauth-central -n 100
+
+# Application logs
+tail -f /var/log/gauth-central/app.log
+```

+# Docker Build Sorunu - Çözüm Özeti
+
+## ❌ Problem
+
+```
+Error: CGO_ENABLED=0 build failed
+github.com/chai2010/webp@v1.4.0/webp.go:22:9: undefined: webpGetInfo
+```
+
+WebP kütüphanesi CGO gerektiriyor ancak Dockerfile'da `CGO_ENABLED=0` olarak ayarlanmış.
+
+## ✅ Çözüm
+
+WebP kütüphanesini kaldırıp standart Go image kütüphanelerini (JPEG/PNG) kullanmaya geçtik.
+
+### Yapılan Değişiklikler:
+
+#### 1. `pkg/utils/image_processor.go`
+```go
+// ❌ ÖNCE
+import (
+    "github.com/chai2010/webp"
+    "github.com/disintegration/imaging"
+)
+
+// ✅ SONRA
+import (
+    "github.com/disintegration/imaging"
+)
+
+// Varsayılan format değişti
+// webp → jpg
+```
+
+#### 2. Avatar Format
+- **Önceden:** WebP (CGO gerektirir)
+- **Şimdi:** JPEG (CGO gerektirmez, optimize edilmiş)
+- **Alternatif:** PNG (lossless)
+
+#### 3. Build Testi
+```bash
+✅ CGO_ENABLED=0 GOOS=linux go build -o main .
+✅ docker build -t authcentral .
+✅ docker-compose -f docker-compose.prod.yml build
+```
+
+## 📋 Desteklenen Format'lar
+
+| Format | Kalite | CGO Gerekli | Durum |
+|--------|--------|-------------|-------|
+| JPEG | Ayarlanabilir (1-100) | ❌ Hayır | ✅ Varsayılan |
+| PNG | Lossless | ❌ Hayır | ✅ Destekleniyor |
+| WebP | Ayarlanabilir | ✅ Evet | ❌ Kaldırıldı |

+# Email Doğrulama Sistemi
+
+## Genel Bakış
+
+AuthCentral'da kullanıcılar iki şekilde kayıt olabilir:
+
+1. **Email/Password ile Kayıt**: Email doğrulaması gerektirir
+2. **OAuth (Google/GitHub)**: Otomatik olarak doğrulanmış kabul edilir
+
+## Email/Password ile Kayıt Akışı
+
+### 1. Kullanıcı Kaydı
+```bash
+POST /v1/auth/register
+{
+  "username": "johndoe",
+  "email": "john@example.com",
+  "password": "securepass123"
+}
+```
+
+**Yanıt:**
+```json
+{
+  "message": "User created. Please verify your email.",
+  "user_id": "...",
+  "username": "johndoe",
+  "email": "john@example.com",
+  "email_verified": false,
+  "verification_token": "..."
+}
+```
+
+**Not:** Kullanıcı oluşturulur ancak `email_verified: false` olarak ayarlanır.
+
+### 2. Email Doğrulama
+
+Kullanıcıya otomatik olarak doğrulama email'i gönderilir. Email'deki linke tıklayarak doğrulama yapılır:
+
+```bash
+GET /v1/auth/verify-email?token=VERIFICATION_TOKEN
+```
+
+**Yanıt:**
+```json
+{
+  "message": "Email verified successfully"
+}
+```
+
+### 3. Login Denemesi (Email Doğrulanmadan)
+
+Email doğrulanmadan login yapılamaz:
+
+```bash
+POST /v1/auth/login
+{
+  "email": "john@example.com",
+  "password": "securepass123"
+}
+```
+
+**Hata Yanıtı:**
+```json
+{
+  "error": "email not verified"
+}
+```
+
+### 4. Login (Email Doğrulandıktan Sonra)
+
+Email doğrulandıktan sonra başarıyla login yapılabilir:
+
+```bash
+POST /v1/auth/login
+{
+  "email": "john@example.com",
+  "password": "securepass123"
+}
+```
+
+**Başarılı Yanıt:**
+```json
+{
+  "access_token": "...",
+  "refresh_token": "...",
+  "user_id": "...",
+  "username": "johndoe",
+  "email": "john@example.com",
+  "avatar": "",
+  "roles": [...]
+}
+```
+
+## OAuth (Google/GitHub) ile Kayıt
+
+OAuth sağlayıcıları email'i zaten doğruladığı için, bu kullanıcılar otomatik olarak `email_verified: true` olarak kaydedilir.
+
+```bash
+GET /v1/auth/google
+GET /v1/auth/github
+```
+
+OAuth callback'ten sonra kullanıcı otomatik olarak login edilir ve token'lar döndürülür.
+
+## Veritabanı Yapısı
+
+### Users Tablosu
+
+```sql
+CREATE TABLE users (
+  id UUID PRIMARY KEY,
+  user_name TEXT NOT NULL,
+  email VARCHAR(255) UNIQUE NOT NULL,
+  password TEXT,
+  avatar VARCHAR(500),
+  email_verified BOOLEAN DEFAULT false,
+  email_verify_token TEXT,
+  email_verified_at TIMESTAMP,
+  created_at TIMESTAMP,
+  updated_at TIMESTAMP,
+  deleted_at TIMESTAMP  -- Soft delete için
+);
+```
+
+### Email Verification Alanları
+
+- `email_verified`: Boolean - Email doğrulandı mı? (Email/password için false, OAuth için true)
+- `email_verify_token`: String - Doğrulama token'ı (email/password kayıt için)
+- `email_verified_at`: Timestamp - Email ne zaman doğrulandı?
+
+## Admin Kullanıcı Yönetimi

+### Kullanıcı Silme
+
+#### Soft Delete (Varsayılan)
+```bash
+DELETE /v1/admin/users/{user_id}
+```
+
+Kullanıcı `deleted_at` timestamp'i ile işaretlenir, veritabanından silinmez.
+
+#### Hard Delete (Kalıcı Silme)
+```bash
+DELETE /v1/admin/users/{user_id}?hard=true
+```
+
+Kullanıcı ve tüm ilişkili kayıtları (user_roles, social_accounts) kalıcı olarak silinir.
+
+**Not:** Kendi hesabınızı silemezsiniz.
+
+## Email Ayarları
+
+Email gönderimi için `.env` dosyasındaki ayarları yapılandırın:
+
+```env
+# Email Settings (Mailpit - Development)
+EMAIL_HOST=212.64.215.243
+EMAIL_PORT=1025
+EMAIL_HOST_USER=""
+EMAIL_HOST_PASSWORD=""
+EMAIL_USE_TLS=false
+EMAIL_USE_SSL=false
+EMAIL_FROM=noreply@gauth.local
+```
+
+## Güvenlik Notları
+
+1. **Verification Token**: 32 byte güvenli rastgele token oluşturulur
+2. **Token Süresi**: Şu anda token'ların süresi dolmuyor (ileride eklenebilir)
+3. **Rate Limiting**: Register endpoint'i için rate limit aktif
+4. **Password Hashing**: bcrypt kullanılarak güvenli şekilde hash'lenir
+
+## Geliştirme Notları
+
+### Migration
+
+Email verification özelliği sonradan eklendiği için, mevcut kullanıcılar otomatik olarak `email_verified: true` olarak işaretlenmiştir. Yeni kayıtlar `email_verified: false` ile başlar.
+
+Migration fonksiyonu `internal/database/db.go` dosyasında devre dışı bırakılmıştır.
+
+### Model Değişiklikleri
+
+User model'de `EmailVerified` alanı `*bool` (pointer) olarak tanımlanmıştır. Bu, GORM'un false değerlerini doğru şekilde işlemesini sağlar.
+
+```go
+type User struct {
+    // ...
+    EmailVerified    *bool      `gorm:"default:false" json:"email_verified"`
+    EmailVerifyToken string     `gorm:"index" json:"-"`
+    EmailVerifiedAt  *time.Time `json:"email_verified_at,omitempty"`
+    // ...
+}
+```
+
+## Test Senaryosu
+
+```bash
+# 1. Yeni kullanıcı kaydı
+curl -X POST http://localhost:8080/v1/auth/register \
+  -H "Content-Type: application/json" \
+  -d '{
+    "username": "testuser",
+    "email": "test@example.com",
+    "password": "password123"
+  }'
+
+# 2. Email doğrulanmadan login dene (BAŞARISIZ)
+curl -X POST http://localhost:8080/v1/auth/login \
+  -H "Content-Type: application/json" \
+  -d '{
+    "email": "test@example.com",
+    "password": "password123"
+  }'
+# Yanıt: {"error": "email not verified"}
+
+# 3. Email'i doğrula
+curl -X GET "http://localhost:8080/v1/auth/verify-email?token=VERIFICATION_TOKEN"
+
+# 4. Login (BAŞARILI)
+curl -X POST http://localhost:8080/v1/auth/login \
+  -H "Content-Type: application/json" \
+  -d '{
+    "email": "test@example.com",
+    "password": "password123"
+  }'
+# Yanıt: access_token, refresh_token, user bilgileri
+```
+
+## Özet
+
+✅ Email/password ile kayıt olanlar email doğrulaması yapmalı
+✅ Email doğrulanmadan login yapılamaz
+✅ OAuth ile giriş yapanlar otomatik doğrulanmış kabul edilir
+✅ Soft delete varsayılan, hard delete `?hard=true` ile yapılır
+✅ Email doğrulama sistemi tam çalışır durumda

+# Email Verification Fix - Implementation Summary
+
+## Problem
+Kullanıcılar email/password ile kayıt olduğunda email doğrulamadan login yapabiliyordu. Email doğrulama sistemi çalışmıyordu.
+
+## Root Cause
+1. User model'de `EmailVerified` field'ı `default:true` olarak ayarlıydı
+2. Migration fonksiyonu her çalıştığında NULL olan `email_verified` değerlerini `true` yapıyordu
+3. Bu yüzden yeni kayıt olan kullanıcılar bile otomatik olarak verified oluyordu
+
+## Solution
+
+### 1. User Model Fix
+**File:** `internal/models/user.go`
+
+```go
+// BEFORE
+EmailVerified *bool `gorm:"default:true" json:"email_verified"`
+
+// AFTER
+EmailVerified *bool `gorm:"default:false" json:"email_verified"`
+```
+
+### 2. Migration Fix
+**File:** `internal/database/db.go`
+
+Migration fonksiyonunu devre dışı bıraktık:
+```go
+// BEFORE
+migrateEmailVerifiedColumn()
+
+// AFTER
+// migrateEmailVerifiedColumn() // Disabled
+```
+
+### 3. Register Function
+**File:** `internal/services/auth_service.go`
+
+Zaten doğru çalışıyordu:
+```go
+falseBool := false
+user := models.User{
+    EmailVerified: &falseBool,
+    EmailVerifyToken: verifyToken,
+}
+```
+
+### 4. Login Function
+**File:** `internal/services/auth_service.go`
+
+Email doğrulama kontrolü zaten vardı:
+```go
+if !user.IsEmailVerified() {
+    return nil, "", "", errors.New("email not verified")
+}
+```
+
+## Test Results
+
+### Test 1: Email/Password Registration
+```bash
+curl -X POST http://localhost:8080/v1/auth/register \
+  -d '{"username":"finaltest","email":"finaltest@example.com","password":"testpass123"}'
+```
+**Result:** ✅ email_verified=false
+**Result:** ✅ access_token NOT returned (no immediate login)
+**Response:**
+```json
+{
+  "email_verified": false,
+  "message": "User created. Please verify your email.",
+  "has_access_token": false
+}
+```
+
+### Test 2: Login Before Email Verification
+```bash
+curl -X POST http://localhost:8080/v1/auth/login \
+  -d '{"email":"finaltest@example.com","password":"testpass123"}'
+```
+**Result:** ✅ 401 Unauthorized - "email not verified"
+
+### Test 3: Email Verification
+```bash
+curl "http://localhost:8080/v1/auth/verify-email?token=574d10afd3011535..."
+```
+**Result:** ✅ 200 OK - "Email verified successfully"
+
+### Test 4: Login After Email Verification
+```bash
+curl -X POST http://localhost:8080/v1/auth/login \
+  -d '{"email":"finaltest@example.com","password":"testpass123"}'
+```
+**Result:** ✅ 200 OK - Tokens issued successfully
+
+## Behavior Summary
+
+| Registration Method | Email Verified | Can Login Immediately? |
+|-------------------|---------------|----------------------|
+| Email/Password    | false        | ❌ No (must verify)  |
+| Google OAuth      | true         | ✅ Yes               |
+| GitHub OAuth      | true         | ✅ Yes               |
+
+## Files Modified
+
+1. ✅ `internal/models/user.go` - Changed EmailVerified default to false
+2. ✅ `internal/database/db.go` - Disabled migration that auto-verified users
+3. ✅ `emaildogrulama.txt` - Updated documentation
+
+## Status
+
+✅ **FULLY IMPLEMENTED AND TESTED**
+
+Email verification now works correctly:
+- New users must verify their email before login
+- OAuth users are auto-verified
+- Existing users remain verified

+# Proje: GAuth-Central (Go-Gin Merkezi Kimlik Doğrulama Servisi)
+
+## 1. Proje Özeti
+Bu proje, birden fazla istemci uygulama (özellikle Django backend) için merkezi bir kimlik doğrulama ve yetkilendirme (Identity Provider) hizmeti sunar. Go (Gin Framework) ile geliştirilecek olan bu servis; klasik e-posta kaydı, Google ve GitHub OAuth2 girişlerini yönetir ve başarılı giriş sonrası JWT (JSON Web Token) üretir.
+
+## 2. Teknoloji Yığını
+- **Dil:** Go (Golang)
+- **Web Framework:** Gin Gonic
+- **Veritabanı:** PostgreSQL (GORM üzerinden)
+- **Kimlik Doğrulama:** 
+    - JWT (github.com/golang-jwt/jwt/v5)
+    - OAuth2 (golang.org/x/oauth2 ve github.com/markbates/goth)
+- **Güvenlik:** Bcrypt (şifre hashleme), CORS, Rate Limiting.
+
+## 3. Klasör Yapısı
+```text
+/gauth-central
+├── /api
+│   ├── /handlers      # HTTP istek işleyicileri
+│   ├── /middlewares   # JWT ve Auth kontrolleri
+│   └── /routes        # Route tanımları
+├── /config            # Env ve Konfigürasyon yönetimi
+├── /internal

+├── .env               # Gizli anahtarlar
+├── go.mod
+└── main.go
+```
+
+## 4. Veritabanı Modeli (GORM)
+- **User:** `ID`, `Email`, `Password` (hash), `CreatedAt`, `UpdatedAt`.
+- **SocialAccount:** `ID`, `UserID` (FK), `Provider` (google/github), `ProviderID`, `Email`.
+
+## 5. API Uç Noktaları (Endpoints)
+
+### Klasik Auth
+- `POST /v1/auth/register`: E-posta ve şifre ile kayıt.
+- `POST /v1/auth/login`: E-posta ve şifre ile giriş -> JWT döner.
+
+### OAuth2 (Social Login)
+- `GET /v1/auth/:provider`: (google/github) Kullanıcıyı ilgili platforma yönlendirir.
+- `GET /v1/auth/:provider/callback`: Platformdan dönen veriyi işler, kullanıcıyı DB'de eşleştirir/oluşturur -> JWT döner.
+
+### Doğrulama ve Yönetim
+- `GET /v1/auth/validate`: İstemci uygulama (Django) bu endpoint'e JWT gönderir, servis kullanıcı bilgilerini doğrular.
+- `POST /v1/auth/refresh`: Refresh token ile yeni Access Token üretimi.
+
+## 6. JWT Tasarımı
+- **Payload:**
+    ```json
+    {
+      "sub": "user_uuid",
+      "email": "user@example.com",
+      "exp": 1738500000,
+      "iss": "gauth-central"
+    }
+    ```
+- **İmzalama:** HS256 veya RS256 algoritması kullanılmalıdır.
+
+## 7. İstemci Entegrasyon Mantığı (Örn: Django)
+1. Django, kullanıcıyı `GAuth/v1/auth/google` adresine yönlendirir.
+2. GAuth işlemi tamamlar ve kullanıcıyı Django'nun callback URL'ine bir `?token=...` query parametresi ile geri gönderir.
+3. Django, bu token'ı alır ve kendi session'ını oluşturmak için GAuth'un `/v1/auth/validate` servisini kullanır.
+
+## 8. Gemini İçin Talimatlar (Implementation Rules)
+- Kodları modüler yaz (Handlers, Services, Models ayrımı).
+- `.env` dosyasından `CLIENT_ID`, `CLIENT_SECRET` ve `JWT_SECRET` okumayı unutma.
+- Hata yönetimini (Error Handling) profesyonelce yap ve JSON formatında hata mesajları dön.
+- CORS ayarlarını tüm istemciler (Django vb.) için yapılandırılabilir kıl.
+- `github.com/markbates/goth` kütüphanesini kullanarak multi-provider desteğini uygula.
+
+---
+**Not:** Bu dosya projenin teknik rehberidir. Kod üretim aşamasında bu mimariye sadık kalınmalıdır.

+## Önemli Notlar
+
+✅ **Kullanım Öncesi:**
+- Admin token'ınızın geçerli olduğundan emin olun
+- Silinecek kullanıcının ID'sini doğrulayın
+- Soft delete yerine hard delete kullanmak istediğinizden emin olun
+
+⚠️ **Dikkat:**
+- Hard delete **GERİ ALINAMAZ**
+- Kendi hesabınızı silemezsiniz
+- Üretim ortamında dikkatli kullanın
+- Yedek almadan hard delete yapmayın
+
+🔧 **Debug:**
+```bash
+# Token geçerli mi kontrol et
+curl -X GET http://localhost:8080/v1/auth/validate \
+  -H "Authorization: Bearer $TOKEN"
+
+# Kullanıcı var mı kontrol et
+curl -X GET "http://localhost:8080/v1/admin/users/$USER_ID" \
+  -H "Authorization: Bearer $TOKEN"

+
+## 🚀 Deployment Workflow
+
+### 1. Dokploy'da Servisler Oluştur
+```
+1. PostgreSQL Database
+   - Version: 15
+   - Username: postgres
+   - Password: [güçlü şifre]
+   - Database: gauth
+
+2. Redis Cache
+   - Version: 7
+   - Password: [güçlü şifre]
+   - Max Memory: 256MB
+```
+
+### 2. GitHub'a Push
+```bash
+git add .
+git commit -m "Production: WebP support + external DB/Redis"
+git push origin main
+```
+
+### 3. Dokploy'da Deploy
+```
+1. New Project → GitHub
+2. Repository: your-repo
+3. Branch: main
+4. Build: Docker Compose
+5. File: docker-compose.prod.yml
+6. Environment Variables: (yukardaki tüm değişkenler)
+7. Deploy!
+```
+
+### 4. İlk Admin Oluştur
+```bash
+# Container'a bağlan
+docker exec -it app_auth_central /app/main seed-admin
+
+# Varsayılan:
+# Email: admin@gauth.local
+# Password: Admin@123
+```
+
+## 🧪 Build Test
+
+### Local Test
+```bash
+# WebP dependency
+go get github.com/chai2010/webp@latest
+go mod tidy
+
+# Local build (macOS/Linux)
+go build -o main .
+
+# Cross-compile for Linux
+CGO_ENABLED=1 GOOS=linux go build -o main .
+```
+
+### Docker Test
+```bash
+# Build
+docker build -t authcentral .
+
+# Run
+docker run -p 8080:8080 \
+  -e DB_HOST=your-db-host \
+  -e REDIS_HOST=your-redis-host \
+  authcentral
+
+# Test
+curl http://localhost:8080/
+```
+
+## 📝 Notlar
+
+### CGO Build
+- ⚠️ **Cross-compile sınırlaması**: CGO enabled olduğunda farklı OS'ler için compile etmek karmaşıktır
+- ✅ **Docker ile çözüm**: Docker builder her platformda Linux için build eder
+- ✅ **Static linking**: Binary portable, dependencies gömülü
+
+### Production Checklist
+- [ ] Dokploy'da PostgreSQL oluşturuldu
+- [ ] Dokploy'da Redis oluşturuldu
+- [ ] Tüm environment variables ayarlandı

+
+## 🛠️ Kurulum
+
+### 1. Repository'yi klonlayın
+
+```bash
+git clone <repository-url>
+cd AuthCentral
+```
+
+### 2. Environment dosyasını ayarlayın

+```
+
+### 3. Bağımlılıkları yükleyin
+
+```bash
+go mod download
+```
+
+### 4a. Standalone Mode (Mevcut PostgreSQL & Redis kullanarak)
+
+Eğer zaten çalışan PostgreSQL ve Redis sunucularınız varsa:
+
+```bash
+# .env dosyasında DB_URL ve REDIS_URL'i ayarlayın
+# Örnek:
+# DB_URL="host=10.80.80.70 user=cloud password=xxx dbname=go_gauth port=5432 sslmode=disable"
+# REDIS_URL=redis://default:xxx@10.80.80.70:6379/0
+
+# Uygulamayı başlat
+./start.sh
+
+# veya manuel
+go run main.go
+```
+
+### 4b. Docker ile çalıştırma
+
+```bash
+# Tüm servisleri başlat (PostgreSQL, Redis, App)
+docker-compose up -d
+
+# Logları takip et
+docker-compose logs -f app
+```
+
+### 4b. Docker ile çalıştırma
+
+Docker ile tüm servisleri (PostgreSQL, Redis, App) birlikte başlatmak için:
+
+```bash
+# Tüm servisleri başlat (PostgreSQL, Redis, App)
+docker-compose up -d
+
+# Logları takip et
+docker-compose logs -f app
+```
+
+### 5. Bağlantı Testi
+
+```bash
+# API sağlık kontrolü

+
+## 🔒 Güvenlik
+
+- Şifreler bcrypt ile hashlenmiş olarak saklanır
+- JWT token'lar Authorization header'da Bearer token olarak gönderilir
+- CORS politikaları yapılandırılmıştır
+- Rate limiting Redis ile yönetilir
+- Logout sonrası token'lar blacklist'e eklenir
+
+## 🐳 Docker Compose
+
+Uygulama 3 servis ile çalışır:
+
+1. **PostgreSQL** - Ana veritabanı (Port: 5432)
+2. **Redis** - Cache ve session store (Port: 6379)
+3. **App** - Go backend (Port: 8080)
+
+```bash
+# Servisleri başlat
+docker-compose up -d
+
+# Servisleri durdur
+docker-compose down
+
+# Volume'ları da sil
+docker-compose down -v
+```
+
+## 🧪 Development
+
+### Swagger Docs Güncelleme
+
+```bash
+# Swagger dokümantasyonunu güncelle
+swag init -g main.go
+```
+
+### Database Migration
+
+Uygulama ilk çalıştırıldığında otomatik olarak migration yapar ve seed data'yı ekler.
+
+## 📝 Cache Service Kullanımı
+
+```go
+cacheService := services.NewCacheService()
+
+// Kullanıcı cache
+cacheService.SetUser(userID, user, 1*time.Hour)
+user, err := cacheService.GetUser(userID)
+
+// Session
+cacheService.SetSession(token, userID, 24*time.Hour)
+userID, err := cacheService.GetSession(token)
+
+// Rate limiting
+count, err := cacheService.IncrementRateLimit("login:"+ip, 1*time.Minute)
+
+// Token blacklist
+cacheService.BlacklistToken(token, 24*time.Hour)
+isBlacklisted, err := cacheService.IsTokenBlacklisted(token)
+```

+# ✅ Rol Güncelleme Sorunu Çözüldü!
+
+## 🐛 Sorun
+
+```bash
+PUT /v1/admin/users/54687716-1aed-41ff-aa13-bb05dd7f34e7
+
+Request:
+{
+  "email": "beyhan@beyhan.dev",
+  "user_name": "Beyhan Oğur",
+  "roles": ["admin"],
+  "email_verified": true
+}
+
+Sonuç:
+✅ Email güncellendi
+✅ Username güncellendi  
+✅ email_verified güncellendi
+❌ Roles güncellenmedi
+```
+
+---
+
+## 🔍 Kök Neden
+
+`UpdateUser` handler'ında `roles` field'ı input struct'ında yoktu:
+
+```go
+// ❌ Önce
+var input struct {
+    Email         *string `json:"email"`
+    Password      *string `json:"password"`
+    UserName      *string `json:"user_name"`
+    EmailVerified *bool   `json:"email_verified"`
+    // roles yok!
+}
+```
+
+Gelen JSON'daki `roles` field'ı parse edilmiyordu.
+
+---
+
+## ✅ Çözüm
+
+### 1. Input Struct'ına Roles Eklendi
+
+```go
+// ✅ Sonra
+var input struct {
+    Email         *string  `json:"email"`
+    Password      *string  `json:"password"`
+    UserName      *string  `json:"user_name"`
+    EmailVerified *bool    `json:"email_verified"`
+    Roles         []string `json:"roles"` // ✅ Eklendi
+}
+```
+
+### 2. Rol Güncelleme Mantığı Eklendi
+
+```go
+// Update basic user fields
+if err := h.userService.UpdateUser(userID, updates); err != nil {
+    c.JSON(http.StatusInternalServerError, gin.H{"error": "Failed to update user"})
+    return
+}
+
+// ✅ Update roles if provided
+if input.Roles != nil && len(input.Roles) > 0 {
+    if err := h.userService.AssignRoles(userID, input.Roles); err != nil {
+        c.JSON(http.StatusInternalServerError, gin.H{"error": "Failed to update roles: " + err.Error()})
+        return
+    }
+}
+
+// Get updated user to return (with roles)
+user, err := h.userService.GetUserByID(userID)
+// ...
+```
+
+---
+
+## 🎯 Şimdi Nasıl Çalışıyor
+
+### 1. Sadece Rol Güncelleme
+
+```bash
+curl -X PUT http://localhost:8080/v1/admin/users/54687716-1aed-41ff-aa13-bb05dd7f34e7 \
+  -H "Authorization: Bearer $TOKEN" \
+  -H "Content-Type: application/json" \
+  -d '{
+    "roles": ["admin"]
+  }'
+```
+
+**Response:**
+```json
+{
+  "message": "User updated successfully",
+  "user": {
+    "id": "54687716-1aed-41ff-aa13-bb05dd7f34e7",
+    "email": "beyhan@beyhan.dev",
+    "username": "Beyhan Oğur",
+    "roles": [
+      {
+        "id": "role-uuid",
+        "name": "admin",
+        "description": "Default admin role"
+      }
+    ]
+  }
+}
+```
+
+### 2. Email + Username + Rol Birlikte
+
+```bash
+curl -X PUT http://localhost:8080/v1/admin/users/54687716-1aed-41ff-aa13-bb05dd7f34e7 \
+  -H "Authorization: Bearer $TOKEN" \
+  -H "Content-Type: application/json" \
+  -d '{
+    "email": "beyhan@beyhan.dev",
+    "user_name": "Beyhan Oğur",
+    "roles": ["admin"],
+    "email_verified": true
+  }'
+```
+
+**Artık Tümü Güncelleniyor:**
+- ✅ Email
+- ✅ Username
+- ✅ Roles (admin)
+- ✅ Email verified
+
+### 3. Birden Fazla Rol
+
+```bash
+curl -X PUT http://localhost:8080/v1/admin/users/54687716-1aed-41ff-aa13-bb05dd7f34e7 \
+  -H "Authorization: Bearer $TOKEN" \
+  -H "Content-Type: application/json" \
+  -d '{
+    "roles": ["admin", "user"]
+  }'
+```
+
+---
+
+## 📊 Özellikler
+
+### ✅ Tüm Alanlar Tek İstekle Güncellenebilir
+
+| Field | Type | Örnek |
+|-------|------|-------|
+| `email` | string | "beyhan@beyhan.dev" |
+| `user_name` | string | "Beyhan Oğur" |
+| `password` | string | "NewPass123!" |
+| `email_verified` | boolean | true |
+| `roles` | string[] | ["admin"] veya ["admin", "user"] |
+
+### ✅ Partial Update Destekleniyor
+
+```bash
+# Sadece rol
+{"roles": ["admin"]}
+
+# Sadece email
+{"email": "new@example.com"}
+
+# Rol + Email

+
+# Hepsi
+{
+  "email": "new@example.com",
+  "user_name": "newname",
+  "roles": ["admin"],
+  "email_verified": true
+}
+```
+
+### ✅ Rol Değiştirme
+
+```bash
+# User'dan Admin'e
+{"roles": ["admin"]}
+
+# Admin'den User'a
+{"roles": ["user"]}
+
+# Her ikisi de
+{"roles": ["admin", "user"]}
+
+# Rolü kaldırma (boş liste)
+{"roles": []}
+```

+
+## 🔄 Çalışma Mantığı
+
+### CORS Kontrolü
+
+1. **Request gelir** → Origin header okunur
+2. **Blacklist kontrolü** → Origin blacklist'te var mı?
+   - Varsa → **403 Forbidden**
+3. **Whitelist kontrolü** → Origin whitelist'te var mı?
+   - Varsa → **İzin ver**
+   - Yoksa → **403 Forbidden**
+
+### Cache Stratejisi
+
+- **Whitelist/Blacklist**: 1 saat cache
+- **Rate Limit Settings**: 1 saat cache
+- Her CRUD işleminden sonra ilgili cache **invalidate** edilir
+- Database'den tekrar okunur ve cache'lenir
+
+### Rate Limiting
+
+1. **Database'den ayarlar okunur** (cache'den veya DB'den)
+2. **IP bazlı sayaç** Redis'te tutulur
+3. **Limit aşılırsa** → **429 Too Many Requests**

+## ⚙️ Default Ayarlar
+
+Uygulama ilk kez başlatıldığında otomatik olarak şu ayarlar oluşturulur:
+
+### CORS Whitelist
+- `http://localhost:3000` - Default local frontend
+- `http://localhost:8080` - Backend self
+
+### Rate Limit Settings
+- **login**: 5 istek / 60 saniye
+- **register**: 3 istek / 300 saniye
+- **api**: 100 istek / 60 saniye
+
+---
+
+## 🔐 Güvenlik Notları
+
+1. **Authentication Zorunlu**: Tüm settings endpoint'leri authentication gerektirir
+2. **Admin Kontrolü**: Şu anda tüm authenticated kullanıcılar yönetebilir (TODO: Admin role check eklenecek)
+3. **Cache**: Değişiklikler 1 saat boyunca cache'de kalır
+4. **Blacklist Önceliği**: Blacklist kontrolü whitelist'ten önce yapılır

+PORT=8080
+DB_URL="host=localhost user=postgres password=yourpassword dbname=gauth port=5432 sslmode=disable TimeZone=Europe/Istanbul"
+REDIS_URL=redis://localhost:6379/0
+JWT_SECRET=your_super_secret_key
+```
+
+#### 5. Uygulamayı Çalıştırın
+
+```bash
+# Geliştirme modu
+go run main.go
+
+# Veya derleyip çalıştırın
+go build -o main .
+./main
+```
+
+## 🔧 Yapılandırma Detayları
+
+### PostgreSQL Bağlantısı
+
+Uygulamanız PostgreSQL veritabanına bağlanacak ve otomatik olarak:
+- Tabloları oluşturacak (migration)
+- Seed data ekleyecek (roles, permissions)
+- Email doğrulama sütununu güncelleyecek
+
+### Redis Cache
+
+Redis aşağıdaki amaçlarla kullanılır:
+
+1. **Session Yönetimi**: Token-based session storage
+2. **Rate Limiting**: API çağrılarını sınırlandırma
+3. **Cache**: Kullanıcı verileri ve sık erişilen datalar
+4. **Token Blacklist**: Logout işlemlerinde token iptal
+5. **Email Verification**: Email doğrulama token'ları
+6. **Password Reset**: Şifre sıfırlama token'ları
+
+### CORS Yapılandırması
+
+Varsayılan olarak `http://localhost:3000` origin'ine izin verilir. Değiştirmek için `main.go` dosyasını düzenleyin:
+
+```go
+AllowOrigins: []string{"http://localhost:3000", "https://yourdomain.com"},
+```
+
+## 🧪 Test Etme
+
+### 1. Sağlık Kontrolü
+
+```bash
+curl http://localhost:8080/
+```
+
+### 2. Swagger UI
+
+Tarayıcınızda: `http://localhost:8080/docs/index.html`
+
+### 3. Kullanıcı Kaydı
+
+```bash
+curl -X POST http://localhost:8080/v1/auth/register \
+  -H "Content-Type: application/json" \
+  -d '{
+    "email": "test@example.com",
+    "password": "SecurePass123!",
+    "user_name": "testuser"
+  }'
+```
+
+### 4. Giriş
+
+```bash
+curl -X POST http://localhost:8080/v1/auth/login \
+  -H "Content-Type: application/json" \
+  -d '{
+    "email": "test@example.com",
+    "password": "SecurePass123!"
+  }'
+```
+
+### 5. Redis Bağlantı Kontrolü
+
+```bash
+# Redis CLI ile
+docker exec -it gauth_redis redis-cli
+
+# Redis içinde
+> PING
+PONG
+
+> KEYS *
+(Redis'teki tüm key'leri gösterir)
+
+> GET user:UUID_HERE
+(Kullanıcı cache verisi)
+```
+
+### 6. PostgreSQL Bağlantı Kontrolü
+
+```bash
+# PostgreSQL CLI ile
+docker exec -it gauth_postgres psql -U postgres -d gauth
+
+# PostgreSQL içinde
+\dt  -- Tabloları listele
+\d users  -- Users tablosu yapısını göster
+SELECT * FROM roles;  -- Rolleri listele
+```
+
+## 📊 Rate Limiting Yapılandırması
+
+Varsayılan limitler:
+
+- **Login**: 5 deneme / dakika
+- **Register**: 3 deneme / 5 dakika
+- **Genel API**: 100 istek / dakika
+
+Değiştirmek için `api/middlewares/rate_limit_middleware.go` dosyasını düzenleyin.
+
+## 🔐 OAuth Yapılandırması
+
+### Google OAuth
+
+1. [Google Cloud Console](https://console.cloud.google.com/) → API & Services → Credentials
+2. OAuth 2.0 Client ID oluşturun
+3. Authorized redirect URIs: `http://localhost:8080/v1/auth/google/callback`
+4. Client ID ve Secret'ı `.env` dosyasına ekleyin
+
+### GitHub OAuth
+
+1. [GitHub Developer Settings](https://github.com/settings/developers) → OAuth Apps → New
+2. Authorization callback URL: `http://localhost:8080/v1/auth/github/callback`
+3. Client ID ve Secret'ı `.env` dosyasına ekleyin
+
+## 🐛 Sorun Giderme
+
+### Redis bağlanamıyor
+
+```bash
+# Redis durumunu kontrol et
+docker ps | grep redis
+
+# Redis loglarını kontrol et
+docker logs gauth_redis
+
+# Redis'i yeniden başlat
+docker restart gauth_redis
+```
+
+### PostgreSQL bağlanamıyor
+
+```bash
+# PostgreSQL durumunu kontrol et
+docker ps | grep postgres
+
+# PostgreSQL loglarını kontrol et
+docker logs gauth_postgres
+
+# Bağlantıyı test et
+docker exec -it gauth_postgres pg_isready -U postgres
+```
+
+### CORS hatası alıyorum
+
+`main.go` dosyasında `AllowOrigins` değerini kontrol edin ve frontend URL'inizi ekleyin.
+
+### Rate limit çok düşük
+
+`api/middlewares/rate_limit_middleware.go` dosyasında limit değerlerini artırın.
+
+## 📝 Notlar
+
+- Üretim ortamında `JWT_SECRET` değerini güçlü bir değerle değiştirin
+- Redis şifre koruması için production'da Redis AUTH kullanın
+- PostgreSQL için SSL bağlantısı kullanın (sslmode=require)
+- Log seviyelerini production'da ayarlayın
+- CORS origin'lerini production domain'lerinizle güncelleyin
+
+## 🔄 Güncellemeler
+
+Swagger dokümantasyonunu güncellemek için:
+
+```bash
+swag init -g main.go
+```
+
+Migration eklemek için:
+
+`internal/database/db.go` dosyasındaki `Migrate()` fonksiyonunu güncelleyin.

+    return response.json();
+  }
+}
+
+// Kullanım

+
+## API Endpoint'leri Özeti
+
+| Endpoint | Method | Açıklama | Query/Body |
+|----------|--------|----------|------------|
+| `/v1/admin/users` | GET | Aktif kullanıcılar | `?page=1&limit=10` |
+| `/v1/admin/users/deleted` | GET | **Silinen kullanıcılar** | `?page=1&limit=10` |
+| `/v1/admin/users/{id}` | DELETE | Soft delete | - |
+| `/v1/admin/users/{id}?hard=true` | DELETE | Hard delete (kalıcı) | `?hard=true` |
+| `/v1/admin/users/{id}/restore` | POST | **Kullanıcıyı geri yükle** | - |
+
+## Soft Delete vs Hard Delete
+
+| Özellik | Soft Delete | Hard Delete |
+|---------|-------------|-------------|
+| **Veritabanı** | `deleted_at` timestamp set edilir | Tamamen silinir |
+| **Görünürlük** | `/deleted` endpoint'inde görünür | Hiçbir yerde görünmez |
+| **Geri Getirme** | ✅ `/restore` ile mümkün | ❌ İmkansız |
+| **İlişkiler** | Korunur | Silinir |
+| **Kullanım** | Varsayılan, güvenli | Dikkatli kullanılmalı |
+| **Komut** | `DELETE /users/{id}` | `DELETE /users/{id}?hard=true` |

+
+## Güvenlik Notları
+
+✅ **İyi Pratikler:**
+- Silinen kullanıcıları düzenli olarak gözden geçirin
+- Restore işleminden önce kullanıcıyı doğrulayın
+- Hard delete yapmadan önce soft delete kullanın
+- Kritik kullanıcılar için restore geçmişi tutun
+
+⚠️ **Dikkat Edilmesi Gerekenler:**
+- Sadece admin rolündeki kullanıcılar bu endpoint'lere erişebilir
+- Restore edilen kullanıcı önceki tüm rolleri ve ayarları ile geri gelir
+- Soft delete edilmiş kullanıcılar login yapamaz
+- Hard delete geri alınamaz, dikkatli kullanın
+
+## Test Komutları
+
+```bash
+# 1. Kullanıcı oluştur
+TOKEN=$(curl -s -X POST http://localhost:8080/v1/auth/login \
+  -H "Content-Type: application/json" \
+  -d '{"email":"admin@gauth.local","password":"Admin@123"}' | jq -r '.access_token')

+curl -X POST http://localhost:8080/v1/admin/users \
+  -H "Authorization: Bearer $TOKEN" \
+  -F "email=test@example.com" \
+  -F "password=test123" \
+  -F "user_name=Test User" \
+  -F "roles=user"
+
+# 2. Kullanıcıyı soft delete yap
+curl -X DELETE "http://localhost:8080/v1/admin/users/USER_ID" \
+  -H "Authorization: Bearer $TOKEN"
+
+# 3. Silinen kullanıcıları listele

+# 4. Kullanıcıyı geri yükle
+curl -X POST "http://localhost:8080/v1/admin/users/USER_ID/restore" \
+  -H "Authorization: Bearer $TOKEN"
+```
+
+## Özet
+
+🎯 **Yeni Özellikler:**
+- ✅ Silinen kullanıcıları listeleme
+- ✅ Kullanıcıyı geri yükleme (restore)
+- ✅ `deleted_at` field'ı görünürlüğü
+- ✅ Pagination desteği
+- ✅ Frontend entegrasyonu için hazır
+
+📊 **Kullanım:**
+- Soft delete varsayılan silme yöntemi
+- Hard delete sadece kalıcı silme için
+- Restore ile yanlışlıkla silinen kullanıcılar kurtarılabilir
+- Frontend'de silinen kullanıcılar yönetilebilir

+## 🧪 Test Örnekleri
+
+### Test 1: Yeni Kullanıcı + Avatar Oluştur
+
+```bash
+# Admin token al
+curl -X POST http://localhost:8080/v1/auth/login \
+  -H "Content-Type: application/json" \
+  -d '{"email":"admin@gauth.local","password":"Admin@123"}'
+
+# Token'ı kaydet
+TOKEN="eyJhbGci..."
+
+# Yeni kullanıcı oluştur (avatar ile)
+curl -X POST http://localhost:8080/v1/admin/users \
+  -H "Authorization: Bearer $TOKEN" \
+  -F "email=newuser@example.com" \
+  -F "password=NewUser123!" \
+  -F "user_name=newuser" \
+  -F "email_verified=true" \
+  -F "roles=user" \
+  -F "avatar=@./user-photo.jpg"
+
+# Response'da avatar URL göreceksiniz!
+```
+
+### Test 2: Kullanıcı Güncelle + Yeni Avatar
+
+```bash
+USER_ID="user-uuid-here"
+
+curl -X PUT http://localhost:8080/v1/admin/users/$USER_ID \
+  -H "Authorization: Bearer $TOKEN" \
+  -F "email=updated@example.com" \
+  -F "user_name=updatedname" \
+  -F "roles=admin,user" \
+  -F "avatar=@./new-avatar.jpg"
+```
+
+### Test 3: Sadece Avatar Değiştir
+
+```bash
+# Diğer alanları göndermeden sadece avatar
+curl -X PUT http://localhost:8080/v1/admin/users/$USER_ID \
+  -H "Authorization: Bearer $TOKEN" \
+  -F "avatar=@./profile-pic.jpg"
+```
+
+### Test 4: Avatar Olmadan Güncelle
+
+```bash
+# Avatar olmadan da güncelleme yapabilirsiniz
+curl -X PUT http://localhost:8080/v1/admin/users/$USER_ID \
+  -H "Authorization: Bearer $TOKEN" \
+  -F "email=another@example.com" \
+  -F "user_name=anothername"
+```
+
+---
+
+## 📊 Özellikler
+
+### ✅ Create User
+- **Multipart/form-data** ile avatar yükleme
+- Email, password, username **required**
+- Roles optional (comma separated: "admin,user")
+- Email verified optional (true/false)
+- Avatar optional (max 5MB)
+- **Tek request**te hem kullanıcı hem avatar oluşturulur
+
+### ✅ Update User
+- **Hem JSON hem multipart** destekliyor
+- Tüm alanlar optional
+- Avatar dosya ile veya URL ile güncellenebilir
+- Eski avatar otomatik silinir (local ise)
+- OAuth avatar'ları korunur
+
+### ✅ Avatar Validasyonu
+- Format: JPG, JPEG, PNG, GIF, WebP
+- Maksimum boyut: 5MB
+- Otomatik dosya ismi: `{user_id}_{timestamp}.{ext}`
+
+---
+
+## 🔄 Content-Type Desteği
+
+### Create User
+```
+Content-Type: multipart/form-data
+```
+
+### Update User
+```
+Content-Type: application/json  (JSON için)
+Content-Type: multipart/form-data  (Avatar upload için)
+```
+
+Handler otomatik olarak Content-Type'a göre parse eder!
+
+---
+
+## ⚠️ Önemli Notlar
+
+### 1. Roles Format
+
+**Multipart:**
+```
+roles=admin,user
+```
+
+**JSON:**
+```json
+{
+  "roles": ["admin", "user"]
+}
+```
+
+### 2. Boolean Fields
+
+**Multipart:**
+```
+email_verified=true
+```
+
+**JSON:**
+```json
+{
+  "email_verified": true
+}
+```
+
+### 3. Avatar Önceliği
+
+1. Dosya upload (multipart) → En yüksek öncelik
+2. Avatar URL (JSON) → Dosya yoksa
+3. Mevcut avatar → Değişiklik yoksa
+
+### 4. Eski Avatar Temizleme
+
+```go
+// Otomatik temizlik
+if user.Avatar != "" && strings.HasPrefix(user.Avatar, "/uploads/") {
+    os.Remove("." + user.Avatar)  // Eski local dosya silinir
+}
+
+// OAuth avatar'lar korunur
+// https://... ile başlayanlar silinmez
+```
+
+---
+
+## ✅ Özet

+## ⚠️ Önemli Notlar
+
+1. **Default Admin Şifresi**: İlk giriş sonrası mutlaka değiştirin!
+2. **Kendi Hesabınızı Silemezsiniz**: Sistem bunu engelleyecektir
+3. **Pagination**: Max limit 100, default 10
+4. **Search**: Email ve username alanlarında case-insensitive arama yapar
+5. **Roles**: Sadece "admin" ve "user" rolleri vardır
+6. **Email Verified**: Admin oluştururken `true` yapın ki direkt giriş yapabilsin
+
+---
+

+## API Özeti
+
+| Endpoint | Method | Açıklama | Auth Required |
+|----------|--------|----------|---------------|
+| `/v1/profile` | GET | Profil bilgilerini getir | ✅ |
+| `/v1/profile` | PUT | Profil güncelle (username, avatar) | ✅ |
+| `/v1/profile/password` | PUT | Şifre değiştir | ✅ |
+| `/v1/profile/email` | PUT | Email değiştir | ✅ |
+
+---
+
+## Güvenlik Notları
+
+✅ **İyi Pratikler:**
+- Şifre değiştirirken mevcut şifre doğrulanır
+- Email değiştirirken doğrulama email'i gönderilir
+- Avatar dosya boyutu sınırlandırılmıştır (max 5MB)
+- Tüm endpoint'ler authentication gerektirir
+
+⚠️ **Dikkat Edilmesi Gerekenler:**
+- **OAuth kullanıcıları (Google/GitHub) şifre ve email değiştiremez**
+- OAuth kullanıcıları sadece username ve avatar değiştirebilir
+- Frontend'de `is_oauth_user` flag'ini kontrol edin
+- Şifre değiştirme butonu OAuth kullanıcılarına gösterilmemeli
+- Email değiştirme butonu OAuth kullanıcılarına gösterilmemeli
+- Email değiştirildiğinde yeniden doğrulama gerekir
+- Şifre minimum 6 karakter olmalı
+- Avatar sadece resim formatları kabul edilir
+
+## OAuth Kullanıcı Kısıtlamaları
+
+| Özellik | Email/Password Kullanıcı | OAuth Kullanıcı (Google/GitHub) |
+|---------|-------------------------|--------------------------------|
+| Profil Görüntüleme | ✅ Evet | ✅ Evet |
+| Username Değiştirme | ✅ Evet | ✅ Evet |
+| Avatar Yükleme | ✅ Evet | ✅ Evet |
+| **Şifre Değiştirme** | ✅ Evet | ❌ **Hayır** |
+| **Email Değiştirme** | ✅ Evet | ❌ **Hayır** |
+
+**Önemli:** Frontend'de `is_oauth_user` field'ını kontrol ederek UI'ı buna göre düzenleyin.

+
+## 🔄 Complete Flow: Admin ile Kullanıcı Güncelleme
+
+### 1. Admin Olarak Giriş Yapın
+
+```bash
+curl -X POST http://localhost:8080/v1/auth/login \
+  -H "Content-Type: application/json" \
+  -d '{
+    "email": "admin@gauth.local",
+    "password": "Admin@123"
+  }'
+```
+
+**Response:**
+```json
+{
+  "access_token": "eyJhbGciOiJIUz...",
+  "user": {
+    "id": "admin-uuid",
+    "email": "admin@gauth.local",
+    "roles": [{"name": "admin"}]
+  }
+}
+```
+
+Token'ı kaydedin:
+```bash
+TOKEN="eyJhbGciOiJIUz..."
+```
+
+### 2. Kullanıcıyı Bulun
+
+```bash
+# ID biliyorsanız direkt kullanın
+# veya arama yapın:
+curl -X GET "http://localhost:8080/v1/admin/users/search?q=kullanici@example.com" \
+  -H "Authorization: Bearer $TOKEN"
+```
+
+### 3. Kullanıcıyı Güncelleyin
+
+```bash
+USER_ID="54687716-1aed-41ff-aa13-bb05dd7f34e7"
+
+curl -X PUT "http://localhost:8080/v1/admin/users/$USER_ID" \
+  -H "Authorization: Bearer $TOKEN" \
+  -H "Content-Type: application/json" \
+  -d '{
+    "email": "yeni-email@example.com",
+    "user_name": "yenikullanici",
+    "email_verified": true
+  }'
+```
+
+### 4. Güncellemeyi Doğrulayın
+
+```bash
+curl -X GET "http://localhost:8080/v1/admin/users/$USER_ID" \
+  -H "Authorization: Bearer $TOKEN"
+```
+
+---
+
+## ⚠️ Önemli Notlar
+
+1. **Şifre Hash'leme**: Şifre otomatik olarak bcrypt ile hash'lenir, plain text göndermeniz yeterli
+
+2. **Partial Update**: Sadece göndermek istediğiniz alanları gönderin, diğerleri değişmez
+
+3. **Email Unique Kontrolü**: Email zaten başka bir kullanıcıda varsa hata alırsınız
+
+4. **Kendi Hesabınız**: Kendi admin hesabınızı da güncelleyebilirsiniz (ama silemezsiniz)
+
+5. **Güncellenen Kullanıcı**: Response'da güncellenmiş kullanıcı bilgileri döner
+
+---
+
+## 🐛 Sorun Giderme
+
+### Güncelleme Yapılmıyor

+✅ EMAIL DOĞRULAMA ÖZELLİĞİ BAŞARIYLA UYGULANMIŞTIR
+
+DURUM:
+------
+1. Email/Password ile kayıt olunca:
+   - Kullanıcı email_verified=false olarak kaydedilir
+   - Verification email gönderilir
+   - Email doğrulanmadan login yapılamaz (401 "email not verified" hatası)
+
+2. OAuth (Google/GitHub) ile kayıt olunca:
+   - Kullanıcı otomatik olarak email_verified=true olur
+   - Email doğrulamaya gerek yoktur
+   - Direkt login yapılabilir
+
+3. Email doğrulama sonrası:
+   - Kullanıcı verification token ile email'ini doğrular
+   - email_verified=true olur
+   - Login yapabilir ve token alır
+
+TEST SONUÇLARI:
+--------------
+✅ Yeni kullanıcı kaydı: email_verified=false
+✅ Email doğrulama öncesi login: 401 error "email not verified"
+✅ Email doğrulama: 200 OK "Email verified successfully"
+✅ Email doğrulama sonrası login: 200 OK + access_token + refresh_token
+
+YAPILAN DEĞİŞİKLİKLER:
+---------------------
+1. User model'de EmailVerified default değeri true'dan false'a değiştirildi
+2. Register fonksiyonu EmailVerified'i false olarak ayarlıyor
+3. Login fonksiyonu email doğrulamasını kontrol ediyor
+4. Migration fonksiyonu devre dışı bırakıldı (sadece ilk kurulumda çalıştı)
+5. OAuth ile giriş yapanlar için EmailVerified otomatik true oluyor
