主要功能: - 实现完整的 RBAC 权限系统（账号、角色、权限的多对多关联） - 基于 owner_id + shop_id 的自动数据权限过滤 - 使用 PostgreSQL WITH RECURSIVE 查询下级账号 - Redis 缓存优化下级账号查询性能（30分钟过期） - 支持多租户数据隔离和层级权限管理 技术实现: - 新增 Account、Role、Permission 模型及关联关系表 - 实现 GORM Scopes 自动应用数据权限过滤 - 添加数据库迁移脚本（000002_rbac_data_permission、000003_add_owner_id_shop_id） - 完善错误码定义（1010-1027 为 RBAC 相关错误） - 重构 main.go 采用函数拆分提高可读性 测试覆盖: - 添加 Account、Role、Permission 的集成测试 - 添加数据权限过滤的单元测试和集成测试 - 添加下级账号查询和缓存的单元测试 - 添加 API 回归测试确保向后兼容 文档更新: - 更新 README.md 添加 RBAC 功能说明 - 更新 CLAUDE.md 添加技术栈和开发原则 - 添加 docs/004-rbac-data-permission/ 功能总结和使用指南 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
