-# 日记系统 - 开发规范
-
-## ⚠️ 血泪教训（2026-04-15）
-
-**问题**：修改前端时丢失了已有的日历功能
-
-**原因**：
-1. 没有先查看现有代码
-2. 没有功能清单对照
-3. 直接在 main 分支修改
-4. 修改后没有验证所有功能
-
---
-
-## 📋 修改代码前的必须步骤
-
-### 1. 查看当前功能清单
-```bash
-# 查看 git 历史了解功能演进
-git log --oneline -20
-
-# 查看当前有哪些文件
-git ls-files
-
-# 查看最近的改动
-git diff HEAD~5
-```
-
-### 2. 备份当前版本
-```bash
-# 创建备份分支
-git branch backup-$(date +%Y%m%d-%H%M)
-
-# 或者至少复制关键文件
-cp frontend/index.html frontend/index.html.bak
-```
-
-### 3. 使用分支开发
-```bash
-# 创建功能分支
-git checkout -b feature/xxx
-
-# 开发完成后合并
-git checkout main
-git merge feature/xxx
-```
-
-### 4. 修改后验证清单
- [ ] 日历组件是否正常
- [ ] 统计面板数据是否正确
- [ ] Tab 切换是否正常
- [ ] API 接口是否可用
- [ ] 云服务器是否同步
-
---
-
-## 📁 必须维护的文档
-
-### 1. FEATURES.md - 功能清单
-记录所有已实现的功能，每次修改前对照检查。
-
-### 2. CHANGELOG.md - 变更日志
-记录每次修改的内容，便于回滚。
-
-### 3. API.md - 接口文档
-记录所有 API 接口，避免删除后端接口。

-## 🔄 标准开发流程
-
-```
-1. 查看功能清单 (FEATURES.md)
-   ↓
-2. 创建备份分支
-   ↓
-3. 创建功能分支开发
-   ↓
-4. 本地测试所有功能
-   ↓
-5. 同步到测试环境验证
-   ↓
-6. 合并到 main
-   ↓
-7. 部署到生产环境
-   ↓
-8. 更新功能清单
-```

-
-## 🛑 禁止操作
-
- ❌ 直接覆盖 `index.html` 而不查看原有内容
- ❌ 在 main 分支直接开发新功能
- ❌ 修改后不验证就部署
- ❌ 删除文件前不确认是否还在使用
-
---
-
-## ✅ 推荐操作
-
- ✅ 小步迭代，每次只改一个功能
- ✅ 使用 `git diff` 查看改动
- ✅ 修改前后截图对比
- ✅ 保持向后兼容
- ✅ 不确定时先问用户

+# 多用户改造方案
+
+## 📋 改动清单
+
+### 1. 数据模型改动
+
+#### DiaryEntry
+```python
+# 添加字段
+user = ForeignKey(User, on_delete=CASCADE, verbose_name='用户')
+
+# 修改唯一约束
+unique_together = ['user', 'date']  # 每个用户每天一条
+```
+
+#### Experience
+```python
+user = ForeignKey(User, on_delete=CASCADE, verbose_name='用户')
+```
+
+#### Task
+```python
+user = ForeignKey(User, on_delete=CASCADE, verbose_name='用户')
+assigned_to = ForeignKey(User, ..., null=True)  # 改为关联用户
+```
+
+#### Comment
+```python
+created_by = ForeignKey(User, on_delete=CASCADE)  # 改为关联用户
+```
+
+### 2. 新增认证 API
+
+```
+POST /api/auth/register/  # 注册
+POST /api/auth/login/     # 登录
+POST /api/auth/logout/    # 登出
+GET  /api/auth/me/        # 当前用户
+```
+
+### 3. API 权限控制
+
+所有 API 添加：
+```python
+permission_classes = [IsAuthenticated]
+
+def get_queryset(self):
+    return Model.objects.filter(user=self.request.user)
+```
+
+### 4. 前端新增
+
+- 登录页面 `/login`
+- 注册页面 `/register`
+- 未登录重定向
+
+---
+
+## ⏱️ 预计工时
+
+- 数据模型迁移：15 分钟
+- 认证 API:30 分钟
+- 权限控制：30 分钟
+- 前端登录界面：30 分钟
+- 测试验证：15 分钟
+
+**总计：约 2 小时**
+
+---
+
+## ⚠️ 注意事项
+
+1. **数据迁移** - 现有数据需要关联到默认用户
+2. **向后兼容** - 保持现有 API 格式
+3. **密码安全** - 使用 Django 内置加密
+4. **用户隔离** - 确保用户只能访问自己的数据
+
+---
+
+_确认改造后开始实施_

+
+### 之前的 HTML/JS 大杂烩
+- ❌ 所有逻辑混在一个文件
+- ❌ 难以维护
+- ❌ 看不清功能边界
+- ❌ 容易误删核心功能
+
+### 现在的 React 组件
+- ✅ 每个功能独立组件
+- ✅ 清晰的依赖关系
+- ✅ 易于测试和维护
+- ✅ 组件级别注释保护
+
+## 🔧 开发指南
+
+### 修改日历功能
+```bash
+# 只需修改这个文件
+src/components/Calendar.js
+
+# 阅读文档
+docs/CALENDAR.md
+
+# 测试
+npm start
+```
+
+### 添加新功能
+1. 在 `components/` 创建新组件
+2. 在 `App.js` 中引入
+3. 运行测试
+
+## 🚀 构建部署
+
+```bash
+# 安装依赖
+npm install
+
+# 开发模式
+npm start
+
+# 生产构建
+npm run build
+
+# 部署构建产物
+cp -r build/* ../frontend/
+```
+
+## ⚠️ 核心组件
+
+**不可删除的组件：**
+- `Calendar.js` - 日历组件 ⭐⭐⭐
+- `App.js` - 主应用 ⭐⭐
+- `StatsPanel.js` - 统计面板 ⭐
+
+修改前必须阅读 `docs/` 对应文档。
