+# 项目初始化指南
+
+## 快速开始
+
+### 1. 配置环境变量
+
+```bash
+# 复制环境变量模板
+cp .env.example .env
+
+# 编辑 .env 文件，配置以下内容：
+# - DJANGO_SECRET_KEY (生成一个安全的密钥)
+# - DB_NAME, DB_USER, DB_PASSWORD, DB_HOST (数据库配置)
+# - ALLOWED_HOSTS (允许的域名)
+```
+
+### 2. 后端初始化
+
+```bash
+cd backend
+
+# 创建虚拟环境
+python -m venv venv
+source venv/bin/activate  # Windows: venv\Scripts\activate
+
+# 安装依赖
+pip install -r requirements.txt
+
+# 配置自定义用户模型 (首次运行需要)
+# 在运行迁移前，确保 apps.users.models.User 已创建
+
+# 运行迁移
+python manage.py migrate
+
+# 创建超级用户
+python manage.py createsuperuser
+
+# 运行开发服务器
+python manage.py runserver
+```
+
+后端将在 http://localhost:8000 启动
+
+### 3. 前端初始化
+
+```bash
+cd frontend
+
+# 安装依赖
+npm install
+
+# 配置环境变量
+cp .env.example .env
+# 编辑 .env，设置 REACT_APP_API_URL
+
+# 启动开发服务器
+npm start
+```
+
+前端将在 http://localhost:3000 启动
+
+## Docker 部署
+
+```bash
+# 构建并启动所有服务
+docker-compose up -d
+
+# 查看日志
+docker-compose logs -f
+
+# 停止服务
+docker-compose down
+
+# 停止并删除卷
+docker-compose down -v
+```
+
+## 数据库配置
+
+### 使用外部 PostgreSQL
+
+在 `.env` 中配置：
+
+```env
+DB_HOST=your-db-host
+DB_PORT=5432
+DB_NAME=your_database_name
+DB_USER=your_database_user
+DB_PASSWORD=your_database_password
+```
+
+### 使用 Docker PostgreSQL
+
+默认配置会启动一个 PostgreSQL 容器，无需额外配置。
+
+## 验证安装
+
+1. 访问 http://localhost:8000/admin - Django 管理后台
+2. 访问 http://localhost:8000/api/ - REST API
+3. 访问 http://localhost:8000/graphql/?graphiql - GraphQL playground
+4. 访问 http://localhost:3000 - React 前端
+
+## 常见问题
+
+### 迁移错误
+如果遇到迁移错误，删除 migrations 文件并重新生成：
+
+```bash
+find . -path "*/migrations/*.py" -not -name "__init__.py" -delete
+python manage.py makemigrations
+python manage.py migrate
+```
+
+### 静态文件收集错误
+```bash
+python manage.py collectstatic --noinput
+```
+
+### 数据库连接错误
+检查 `.env` 文件中的数据库配置是否正确。

+
+## 核心功能
+
+### 1. 用户认证
+
+**JWT 认证流程：**
+1. 用户发送 email + password 到 `/api/auth/login/`
+2. 后端验证并返回 access_token 和 refresh_token
+3. 前端保存 tokens 到 localStorage
+4. 后续请求在 Header 中携带 Bearer token
+5. Token 过期时自动使用 refresh_token 刷新
+
+**自定义用户模型：**
+```python
+# apps/users/models.py
+class User(AbstractUser):
+    email = models.EmailField(unique=True)
+    avatar = models.ImageField(upload_to='avatars/')
+    USERNAME_FIELD = 'email'
+```
+
+### 2. REST API
+
+**端点：**
+- `POST /api/auth/login/` - 登录获取 token
+- `POST /api/auth/token/refresh/` - 刷新 token
+- `GET /api/users/` - 获取用户列表
+- `GET /api/users/me/` - 获取当前用户
+- `GET /api/users/:id/` - 获取特定用户
+
+### 3. GraphQL
+
+**Schema：**
+```graphql
+type User {
+  id: ID!
+  email: String!
+  username: String!
+}
+
+type Query {
+  allUsers: [User!]!
+  me: User
+}
+```
+
+访问 `/graphql/?graphiql` 查看调试界面。
+
+### 4. 状态管理 (MobX)
+
+**AuthStore：**
+- 管理认证状态
+- 处理登录/登出
+- 保存和读取 tokens
+
+**UserStore：**
+- 获取当前用户信息
+- 管理用户数据状态
+
+## 开发流程
+
+### 1. 添加新的 API 端点
+
+```python
+# apps/yourapp/views.py
+class YourViewSet(viewsets.ModelViewSet):
+    queryset = YourModel.objects.all()
+    serializer_class = YourSerializer
+
+# apps/yourapp/urls.py
+router = DefaultRouter()
+router.register(r'endpoint', YourViewSet)
+```
+
+### 2. 添加新的 MobX Store
+
+```javascript
+// src/stores/YourStore.js
+import { makeAutoObservable } from 'mobx';
+
+class YourStore {
+  data = null;
+  loading = false;
+
+  constructor() {
+    makeAutoObservable(this);
+  }
+
+  async fetchData() {
+    this.loading = true;
+    // API 调用
+    this.loading = false;
+  }
+}
+
+export default YourStore;
+```
+
+### 3. 添加新的 React 组件
+
+```javascript
+// src/components/YourComponent.js
+import React from 'react';
+import styled from 'styled-components';
+
+const Container = styled.div`
+  padding: 20px;
+`;
+
+function YourComponent() {
+  return <Container>Your content</Container>;
+}
+
+export default YourComponent;
+```
+
+## 部署配置
+
+### Docker Compose 服务
+
+**backend：**
+- 基于 Python 3.11
+- 运行 Gunicorn
+- 暴露 8000 端口
+- 挂载 static 和 media 卷
+
+**frontend：**
+- 基于 Node 18 构建
+- 使用 nginx 作为服务器
+- 暴露 80 端口
+- 代理 API 请求到 backend
+
+**db：**
+- PostgreSQL 15
+- 持久化数据卷
+
+### Nginx 配置
+
+- `/` → React 应用
+- `/api/*` → Django 后端
+- `/graphql/*` → Django GraphQL
+- `/media/*` → Django media
+- `/static/*` → Django static
+
+## 安全注意事项
+
+1. **生产环境必须：**
+   - 设置 `DJANGO_SECRET_KEY` 为强随机值
+   - `DEBUG=False`
+   - 配置 `ALLOWED_HOSTS`
+   - 启用 HTTPS
+   - 设置 `CORS_ALLOWED_ORIGINS`
+
+2. **数据库：**
+   - 使用强密码
+   - 不暴露到公网
+   - 定期备份
+
+3. **JWT：**
+   - Token 过期时间合理配置
+   - 刷新 token 轮换
+   - 生产环境使用 HTTPS
+
+## 下一步开发建议
+
+1. **后端：**
+   - 添加更多业务 apps
+   - 实现权限控制
+   - 添加 API 文档 (Swagger)
+   - 实现文件上传功能
+
+2. **前端：**
+   - 创建登录/注册页面
+   - 添加路由保护
+   - 实现加载状态处理
+   - 添加错误处理
+
+3. **部署：**
+   - 配置 HTTPS (Let's Encrypt)
+   - 设置 CI/CD
+   - 配置日志收集
+   - 实现自动备份

+├── docker-compose.yml
+└── .env.example
+```
+
+## Setup Instructions
+
+### 1. Environment Variables
+
+Copy `.env.example` to `.env` and configure:
+
+```bash
+cp .env.example .env
+```
+
+Update the following variables:
+- `DJANGO_SECRET_KEY` - Generate a secure secret key
+- Database credentials (DB_NAME, DB_USER, DB_PASSWORD)
+- `ALLOWED_HOSTS` - Add your domain(s)
+
+### 2. PostgreSQL Configuration
+
+If using external PostgreSQL (already deployed):
+
+Update `.env` with your database credentials:
+```env
+DB_HOST=your-db-host
+DB_PORT=5432
+DB_NAME=your_database_name
+DB_USER=your_database_user
+DB_PASSWORD=your_database_password
+```
+
+If using Docker PostgreSQL:
+
+The default values in `docker-compose.yml` will work.
+
+### 3. Backend Setup
+
+```bash
+cd backend
+
+# Create virtual environment
+python -m venv venv
+source venv/bin/activate  # On Windows: venv\Scripts\activate
+
+# Install dependencies
+pip install -r requirements.txt
+
+# Run migrations
+python manage.py migrate
+
+# Create superuser
+python manage.py createsuperuser
+
+# Run development server
+python manage.py runserver
+```
+
+### 4. Frontend Setup
+
+```bash
+cd frontend
+
+# Install dependencies
+npm install
+
+# Start development server
+npm start
+```
+
+### 5. Docker Deployment
+
+```bash
+# Build and start all services
+docker-compose up -d
+
+# View logs
+docker-compose logs -f
+
+# Stop services
+docker-compose down
+```
+
+## API Endpoints
+
+### REST API
+- `/api/users/` - User management
+- `/api/users/me/` - Current user
+- `/api/auth/token/` - Login (POST)
+- `/api/auth/token/refresh/` - Refresh token (POST)
+
+### GraphQL
+- `/graphql/` - GraphQL endpoint
+- `/graphql/?graphiql` - GraphQL playground
+
+## Development
+
+### Running Backend
+```bash
+cd backend
+python manage.py runserver
+```
+
+### Running Frontend
+```bash
+cd frontend
+npm start

+# API 测试指南
+
+## 测试后端 API
+
+### 1. 获取 Token (登录)
+
+```bash
+curl -X POST http://localhost:8000/api/auth/login/ \
+  -H "Content-Type: application/json" \
+  -d '{
+    "email": "your@email.com",
+    "password": "your_password"
+  }'
+```
+
+响应示例：
+```json
+{
+  "access": "eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9...",
+  "refresh": "eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9...",
+  "user": {
+    "id": 1,
+    "email": "your@email.com",
+    "username": "your_username",
+    "first_name": "First",
+    "last_name": "Last"
+  }
+}
+```
+
+### 2. 刷新 Token
+
+```bash
+curl -X POST http://localhost:8000/api/auth/token/refresh/ \
+  -H "Content-Type: application/json" \
+  -d '{
+    "refresh": "your_refresh_token"
+  }'
+```
+
+### 3. 获取用户列表 (需要认证)
+
+```bash
+curl -X GET http://localhost:8000/api/users/ \
+  -H "Authorization: Bearer your_access_token"
+```
+
+### 4. 获取当前用户
+
+```bash
+curl -X GET http://localhost:8000/api/users/me/ \
+  -H "Authorization: Bearer your_access_token"
+```
+
+## GraphQL 测试
+
+访问 http://localhost:8000/graphql/?graphiql
+
+### 查询所有用户
+
+```graphql
+query {
+  allUsers {
+    id
+    email
+    username
+    firstName
+    lastName
+  }
+}
+```
+
+### 查询当前用户
+
+```graphql
+query {
+  me {
+    id
+    email
+    username
+    firstName
+    lastName
+  }
+}
+```
+
+## Postman 集合
+
+你可以导入以下 Postman 集合来测试 API：
+
+### 环境变量
+- `base_url`: http://localhost:8000
+- `access_token`: (登录后自动填充)
+
+### 请求示例
+
+**1. 登录**
+- Method: POST
+- URL: `{{base_url}}/api/auth/login/`
+- Body:
+```json
+{
+  "email": "test@example.com",
+  "password": "testpass123"
+}
+```
+- Tests (自动提取 token):
+```javascript
+var jsonData = pm.response.json();
+pm.environment.set("access_token", jsonData.access);
+```
+
+**2. 获取用户**
+- Method: GET
+- URL: `{{base_url}}/api/users/`
+- Headers:
+```
+Authorization: Bearer {{access_token}}
+```
+
+**3. 获取当前用户**
+- Method: GET
+- URL: `{{base_url}}/api/users/me/`
+- Headers:
+```
+Authorization: Bearer {{access_token}}
+```
+
+## 自动化测试
+
+### 后端测试
+
+```bash
+cd backend
+python manage.py test
+```
+
+### 前端测试
+
+```bash
+cd frontend
+npm test
+```
+
+## 常见错误
+
+### 401 Unauthorized
+- Token 过期，使用 refresh_token 刷新
+- Token 格式错误，确保 `Bearer` 前缀存在
+- Token 被吊销
+
+### 403 Forbidden
+- 权限不足，检查用户是否有相应权限
+- CSRF token 问题（开发环境可能遇到）
+
+### 404 Not Found
+- 端点不存在，检查 URL 路径
+- 检查 Django 是否正确启动
+
+### 500 Server Error
