BREAKING CHANGES:
- Removed OU=Roles from LDAP structure, role groups now created directly in department OU
- Role groups use ROLE_<Name> naming convention (similar to DEP_, POS_)
New features:
- RoleAssignment model: allows assigning roles to ANY employee, not just department members
- New API endpoints: /assign/, /revoke/, /assignments/ on DepartmentRoleViewSet
- Permission system updated: has_dept_perm() checks RoleAssignment first
- Employee profile shows external roles with 'внешняя роль' badge
- Employee list filter includes role-only employees with department_relation field
- Role assignment modal now searches all employees via AJAX
LDAP changes:
- _ensure_role_group(): creates ROLE_<Name> group in department OU
- assign_role(), revoke_role(): manage RoleAssignment + LDAP sync
- rename_role_group(), delete_role_group(): full lifecycle support
- Removed all references to OU=Roles
Migrations:
- 0035: Create RoleAssignment model
- 0036: Data migration from EmployeeDepartment.role
Tests:
- 7 new tests for role assignment (all passing)
Docs:
- 9 detailed reports on architecture, models, API, LDAP, tests
Implemented automatic movement of dismissed employees to dedicated OU.
Core Changes:
- Configuration: Added LDAP_DISMISSED_BASE setting for dismissed employees OU
- Utility: Created get_base_dn_for_employee() to determine target OU by is_active status
- Service Layer: Modified DepartmentService.remove_member() to use status-based OU selection
- View Logic: Updated EmployeeActionViewSet._apply_effects() to:
* Deactivate employee BEFORE removing from departments (critical for correct OU routing)
* Loop through all departments and call remove_member() for each
* Handle restoration: move from OU=Dismissed back to OU=Users on activation
Infrastructure:
- Management Command: ensure_dismissed_ou.py to create OU=Dismissed in AD
* Checks OU existence before creation
* Supports --force flag for recreation
* Configurable description
Testing:
- test_dismissal_moves_to_dismissed_ou: Verifies dismissal → OU=Dismissed movement
- test_restoration_moves_from_dismissed_to_users: Verifies activation → OU=Users movement
Edge Cases Handled:
- Repeat dismissal: Idempotent (already inactive employees stay in OU=Dismissed)
- Restoration: Automatic move from OU=Dismissed to OU=Users on any activating action
- Missing OU: ensure_container_exists() creates OU=Dismissed if missing (fallback to OU=Users on error)
- LDAP errors: Graceful logging without blocking database operations
Technical Details:
- OU=Dismissed: OU=Dismissed,OU=company,DC=robotail,DC=local
- Dismissal flow: is_active=False → deactivate EmployeeDepartment → update LDAP UAC → remove from all departments
- Restoration flow: is_active=True → update LDAP UAC → check current OU → move if in OU=Dismissed
- Backward compatible: Works with existing dismissals (they will move to OU=Dismissed on next department change)
