| name | Django Web框架 |
| description | 当开发Django应用时，分析项目结构，优化ORM查询，解决性能问题。验证MVC架构，设计企业级Web应用，和最佳实践。 |
| license | MIT |
Django是Python最强大的Web框架。不当的Django配置会导致性能问题、安全漏洞和维护困难。在开发Django应用前需要仔细分析项目需求。
核心原则: 好的Django应用应该遵循MTV模式、高效ORM、安全配置、易于扩展。坏的Django应用会导致性能瓶颈、安全风险和维护困难。
始终:
触发短语:
问题:
数据库查询慢，N+1查询问题
错误示例:
- 缺少select_related/prefetch_related
- 循环查询数据库
- 未使用数据库索引
- 复杂聚合查询
解决方案:
1. 使用select_related优化外键查询
2. 使用prefetch_related优化多对多查询
3. 添加适当的数据库索引
4. 使用缓存机制
问题:
安全漏洞，数据泄露风险
错误示例:
- 调试模式在生产环境开启
- CSRF保护未启用
- SQL注入风险
- XSS攻击漏洞
解决方案:
1. 生产环境关闭DEBUG模式
2. 启用CSRF保护中间件
3. 使用ORM防止SQL注入
4. 模板自动转义防止XSS
问题:
代码组织混乱，维护困难
错误示例:
- 应用职责不清晰
- 配置文件混乱
- 静态文件管理不当
- 模板结构不合理
解决方案:
1. 合理划分应用职责
2. 分环境配置管理
3. 统一静态文件处理
4. 优化模板继承结构
