+sudo systemctl restart nginx
+```
+
+---
+
+## 生产环境配置
+
+### 1. Django 配置
+
+```python
+# config/settings/prod.py
+DEBUG = False
+
+# 安全设置
+SECURE_BROWSER_XSS_FILTER = True
+SECURE_CONTENT_TYPE_NOSNIFF = True
+SECURE_HSTS_SECONDS = 31536000
+SECURE_HSTS_INCLUDE_SUBDOMAINS = True
+SECURE_HSTS_PRELOAD = True
+SECURE_SSL_REDIRECT = True
+
+# 允许的主机
+ALLOWED_HOSTS = ['yourdomain.com']
+
+# 数据库（使用 Unix socket 更快）
+DATABASES = {
+    'default': {
+        'ENGINE': 'django.db.backends.postgresql',
+        'NAME': 'citywiki',
+        'USER': 'citywiki',
+        'PASSWORD': 'your_password',
+        'HOST': '/var/run/postgresql',
+        'PORT': '',
+    }
+}
+```
+
+### 2. Gunicorn 配置
+
+创建 `gunicorn.conf.py`：
+
+```python
+bind = "127.0.0.1:8000"
+workers = 3
+worker_class = "sync"
+worker_connections = 1000
+max_requests = 1000
+max_requests_jitter = 50
+timeout = 30
+keepalive = 2
+```
+
+启动 Gunicorn：
+
+```bash
+gunicorn -c gunicorn.conf.py config.wsgi:application
+```
+
+### 3. Systemd 服务（自动重启）
+
+创建 `/etc/systemd/system/citywiki.service`：
+
+```ini
+[Unit]
+Description=CityWiki Django App
+After=network.target
+
+[Service]
+User=www-data
+Group=www-data
+WorkingDirectory=/path/to/backend
+ExecStart=/path/to/backend/venv/bin/gunicorn -c gunicorn.conf.py config.wsgi:application
+Restart=always
+
+[Install]
+WantedBy=multi-user.target
+```
+
+启动服务：
+
+```bash
+sudo systemctl daemon-reload
+sudo systemctl start citywiki
+sudo systemctl enable citywiki
+```
+
+---
+
+## 监控和日志
+
+### 1. Django 日志配置
+
+```python
+LOGGING = {
+    'version': 1,
+    'disable_existing_loggers': False,
+    'handlers': {
+        'file': {
+            'level': 'INFO',
+            'class': 'logging.FileHandler',
+            'filename': '/var/log/citywiki/django.log',
+        },
+    },
+    'loggers': {
+        'django': {
+            'handlers': ['file'],
+            'level': 'INFO',
+            'propagate': True,
+        },
+    },
+}
+```
+
+### 2. Nginx 日志
+
+```nginx
+access_log /var/log/nginx/citywiki_access.log;
+error_log /var/log/nginx/citywiki_error.log;
+```
+
+---
+
+## 数据备份
+
+### PostgreSQL 备份
+
+```bash
+# 备份
+pg_dump -U citywiki citywiki > backup_$(date +%Y%m%d).sql
+
+# 恢复
+psql -U citywiki citywiki < backup_20260409.sql
+```
+
+### 媒体文件备份
+
+```bash
+rsync -avz /path/to/backend/media/ /backup/media/
+```
+
+---
+
+## HTTPS 配置（Let's Encrypt）
+
+```bash
+# 安装 Certbot
+sudo apt-get install certbot python3-certbot-nginx
+
+# 获取证书
+sudo certbot --nginx -d yourdomain.com
+
+# 自动续期
+sudo certbot renew --dry-run
+```
+
+---
+
+## 性能优化
+
+### 1. 数据库优化
+
+```sql
+-- 添加索引
+CREATE INDEX idx_articles_region ON articles(region_id);
+CREATE INDEX idx_articles_status ON articles(publish_status);
+CREATE INDEX idx_services_region ON featured_services(region_id);
+CREATE INDEX idx_services_status ON featured_services(publish_status);
+CREATE INDEX idx_comments_target ON comments(target_type, target_id);
+```
+
+### 2. 缓存（Redis）
+
+```bash
+# 安装 Redis
+sudo apt-get install redis-server
+```
+
+配置 Django 使用 Redis：
+
+```python
+CACHES = {
+    'default': {
+        'BACKEND': 'django.core.cache.backends.redis.RedisCache',
+        'LOCATION': 'redis://127.0.0.1:6379/1',
+    }
+}
+```
+
+### 3. CDN 加速
+
+使用 Cloudflare 或阿里云 CDN 加速静态文件访问。
+
+---
+
+## 故障排查
+
+### 1. 数据库连接失败
+
+```bash
+# 检查 PostgreSQL 是否运行
+sudo systemctl status postgresql
+
+# 检查端口
+sudo netstat -tuln | grep 5432
+```
+
+### 2. 静态文件 404
+
+```bash
+# 重新收集静态文件
+cd backend
+python manage.py collectstatic --noinput
+```
+
+### 3. Nginx 502 Bad Gateway
+
+```bash
+# 检查 Django 是否运行
+ps aux | grep gunicorn
+
+# 重启 Django
+sudo systemctl restart citywiki
+```
+
+---
+
+## 更新部署
+
+```bash
+# 拉取最新代码
+git pull origin master
+
+# 后端更新
+cd backend
+source venv/bin/activate
+pip install -r requirements.txt
+python manage.py migrate
+python manage.py collectstatic --noinput
+sudo systemctl restart citywiki
+
+# 前端更新
+cd frontend
+npm install
+npm run build
+sudo systemctl restart nginx
+```
+
+---

+
+## 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

+# 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
+- 检查 Django 日志
+- 检查数据库连接
+- 检查代码语法错误

+| 版主 | 管理指定版块内容 | 管辖范围内内容初审、申请创建版块 |
+| AI审核员 | 内容最终审核 | 版主审核通过后的内容进行最终审核，决定是否发布 |
+| 管理员 | 全局管理 | 版主申请审核、版主权限管理、全局内容管理 |
+
+### 3.2 版主权限规则
+- 版主只能审核其管辖范围内的内容
+- 上级版主不需要复核下级版主审核的内容
+- 上级版主有权暂时限制下级版主的权限
+- 版主权限限制可由上级版主或管理员操作
+
+### 3.3 版主申请机制
+- 用户可以申请成为特定版块的版主
+- 创建版块需要管理员批准
+- 版块创建后，特定时间内需要征集到足够支持人数

+
+| 管辖层级 | 军衔 |
+|----------|------|
+| 省级 | 将军 |
+| 市级 | 校官 |
+| 县级 | 尉官 |
+| 镇村级 | 士兵 |
+
+---
+
+## 4. 版块层级结构
+
+```
+省 → 市 → 县 → 乡镇（街道） → 村（居委会）
+```
+
+---
+
+## 5. 内容审核流程
+
+### 5.1 内容提交流程
+
+文章和特色服务提交需经过以下审核流程：
+
+```
+提交 → 版主初审 → AI审核 → 发布
+         ↓          ↓
+      拒绝      拒绝
+```
+
+### 5.2 审核规则
+- 版主审核通过后，内容进入AI审核
+- AI审核通过后，内容正式发布

+## 9. 技术实现要点
+
+### 9.1 版主审核权限判断逻辑
+
+用户A可以审核内容B的条件：
+1. 用户A是版主且权限状态为正常
+2. 内容B的版块 == 用户A管辖的版块 或 内容B的版块在用户A管辖范围内
+
+### 9.2 版块申请自动化逻辑
+- 截止时间到达且支持人数不足 → 自动取消版主申请
+- 版主申请取消后，相关支持记录保留但状态标记为已取消
+
+### 9.3 内容审核流程自动化
+- 版主审核通过 → 自动提交到AI审核队列
+- AI审核完成 → 自动更新内容发布状态
+
+### 9.4 支持人数统计
+- 实时统计版主申请的支持人数
+- 定期更新支持人数到版主申请表
+
+---
+
+## 10. 待确认细节
+
+以下细节待进一步确认：
+
+1. **版块申请截止时间和支持人数**
+   - 征集期具体时长？
+   - 多少人数算"足够支持人数"？
+
+2. **评分机制**
+   - 评分采用几星制？（1-5星？）
+   - 评分是否需要写评价？
+
+3. **城市信息数据字段**
+   - 固定模板 vs 灵活标签
+
+4. **AI审核拒绝后的处理**
+   - 提交者能看到拒绝原因吗？
+   - 是否可以申诉？
+
+5. **分享卡片生成**
+   - 卡片样式和内容格式？
+
+6. **版主权限限制的具体逻辑**
+   - 部分限制限制哪些权限？
+   - 限制的最长时限？
+
