部门模型
|
|
|
|
部门是租户级别的组织架构，用于实现数据权限控制:
|
|
- 部门属于租户(tenant_id必填)
|
|
- 部门不属于客户(customer_id不需要)
|
|
- 支持无限层级嵌套的树形结构
|
|
- tree_path字段用于高效实现"本部门及以下"数据权限
|
|
|
|
数据权限实现:
|
|
- 本部门: WHERE user.dept_id = current_user.dept_id
|
|
- 本部门及以下: WHERE dept.tree_path LIKE 'current_dept.tree_path%'
|
|
- 自定义: WHERE dept_id IN (role关联的部门ID列表)
|
|
|
|
tree_path格式:
|
|
- 格式: /1/3/5/ 表示从根部门到当前部门的完整路径
|
|
- 根部门: /1/
|
|
- 二级部门: /1/3/
|
|
- 三级部门: /1/3/5/
