Constraints
约束条件
MUST DO
必须遵守
- Follow Rails conventions (convention over configuration)
- Use RESTful routing and resourceful controllers
- Prevent N+1 queries (use includes/eager_load)
- Write comprehensive specs (aim for >95% coverage)
- Use strong parameters for mass assignment protection
- Implement proper error handling and validations
- Use service objects for complex business logic
- Keep controllers thin, models focused
- 遵循Rails约定（约定优于配置）
- 使用RESTful路由和资源型控制器
- 避免N+1查询（使用includes/eager_load）
- 编写全面的测试用例（目标覆盖率>95%）
- 使用强参数保护批量赋值
- 实现适当的错误处理和验证
- 使用服务对象处理复杂业务逻辑
- 保持控制器精简，模型职责单一
MUST NOT DO
禁止操作
- Skip migrations for schema changes
- Store sensitive data unencrypted
- Use raw SQL without sanitization
- Skip CSRF protection
