|
||||
|
||||
## What Was Implemented
|
||||
|
||||
### 1. Database Schema Changes
|
||||
|
||||
**New Roles Added** (to `roles` table):
|
||||
```sql
|
||||
INSERT INTO roles (name, description, level) VALUES
|
||||
('warehouse_manager', 'Manager - Warehouse - Full warehouse module access', 75),
|
||||
('warehouse_worker', 'Worker - Warehouse - Input-only warehouse access', 35);
|
||||
```
|
||||
|
||||
**New Table Created** (`worker_manager_bindings`):
|
||||
```sql
|
||||
CREATE TABLE worker_manager_bindings (
|
||||
id INT AUTO_INCREMENT PRIMARY KEY,
|
||||
manager_id INT NOT NULL, -- Who supervises
|
||||
worker_id INT NOT NULL, -- Who is being supervised
|
||||
warehouse_zone VARCHAR(100), -- Zone restriction (NULL = all zones)
|
||||
is_active TINYINT(1) DEFAULT 1,
|
||||
created_at TIMESTAMP,
|
||||
updated_at TIMESTAMP,
|
||||
UNIQUE KEY unique_binding (manager_id, worker_id),
|
||||
FOREIGN KEY (manager_id) REFERENCES users(id) ON DELETE CASCADE,
|
||||
FOREIGN KEY (worker_id) REFERENCES users(id) ON DELETE CASCADE,
|
||||
CHECK (manager_id != worker_id)
|
||||
);
|
||||
```
|
||||
|
||||
**Files Modified**:
|
||||
- `init_db.py` - Added warehouse roles and worker_manager_bindings table
|
||||
- `initialize_db.py` - Added warehouse roles and worker_manager_bindings table
|
||||
|
||||
### 2. Access Control System
|
||||
|
||||
**Role Definitions** (in `access_control.py`):
|
||||
```python
|
||||
ROLES = {
|
||||
'warehouse_manager': {
|
||||
'level': 75,
|
||||
'modules': ['warehouse'],
|
||||
'description': 'Full access to warehouse module'
|
||||
},
|
||||
'warehouse_worker': {
|
||||
'level': 35,
|
||||
'modules': ['warehouse'],
|
||||
'description': 'Limited access - input only, no reports'
|
||||
}
|
||||
# ... existing roles
|
||||
}
|
||||
```
|
||||
|
||||
**Module Permissions** (in `access_control.py`):
|
||||
```python
|
||||
MODULE_PERMISSIONS['warehouse'] = {
|
||||
'sections': {
|
||||
'input': {
|
||||
'warehouse_manager': ['view', 'create', 'edit', 'delete'],
|
||||
'warehouse_worker': ['view', 'create', 'edit']
|
||||
},
|
||||
'reports': {
|
||||
'warehouse_manager': ['view', 'export', 'download', 'analytics'],
|
||||
'warehouse_worker': [] # No report access
|
||||
},
|
||||
'locations': {
|
||||
'warehouse_manager': ['view', 'create', 'edit', 'delete'],
|
||||
'warehouse_worker': ['view'] # View only
|
||||
},
|
||||
'management': {
|
||||
'warehouse_manager': ['manage_workers'],
|
||||
'warehouse_worker': [] # No management access
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
**Helper Functions** (in `access_control.py`):
|
||||
- `can_access_warehouse_input(user_role)` - Check input page access
|
||||
- `can_access_warehouse_reports(user_role)` - Check report access (manager only)
|
||||
- `can_manage_warehouse_workers(user_role)` - Check worker management access
|
||||
- `get_worker_warehouse_zone(user_id)` - Get worker's zone restriction
|
||||
- `get_manager_workers(manager_id)` - Get all assigned workers
|
||||
- `validate_worker_zone_access(worker_id, manager_id, zone)` - Validate zone access
|
||||
- `build_zone_filter_sql(user_id, user_role)` - Generate SQL filter for queries
|
||||
|
||||
**Files Modified**:
|
||||
- `access_control.py` - Complete role and permission system
|
||||
|
||||
### 3. Worker Management System
|
||||
|
||||
**New Module Created** (`app/modules/settings/warehouse_worker_management.py`):
|
||||
|
||||

## Worker-Manager Binding Model
|
||||
|
||||
### Key Concept: Zone-Restricted Access
|
||||
|
||||
**Scenario**: Maria Garcia (warehouse_manager) supervises 2 workers with zone restrictions:
|
||||
|
||||
```
|
||||
Manager: Maria Garcia (ID=6, role=warehouse_manager)
|
||||
├─ Worker: David Chen (ID=15, zone="Cold Storage")
|
||||
└─ Worker: Eve Martinez (ID=16, zone="High Shelf")
|
||||
|
||||
Bindings in database:
|
||||
├─ binding_4: manager_id=6, worker_id=15, zone="Cold Storage"
|
||||
└─ binding_5: manager_id=6, worker_id=16, zone="High Shelf"
|
||||
|
||||
Results:
|
||||
✓ David can input ONLY in "Cold Storage" zone
|
||||
✓ Eve can input ONLY in "High Shelf" zone
|
||||
✓ Maria can see data from both David and Eve
|
||||
✓ Maria can filter reports by zone
|
||||
✓ David cannot see Eve's data
|
||||
✓ Eve cannot see David's data
|
||||
```
|
||||
|
||||
### Binding Types
|
||||
|
||||
1. **Zone-Restricted** (zone = specific zone name):
|
||||
- Worker can ONLY input to that zone
|
||||
- Example: zone = "Cold Storage"
|
||||
|
||||
2. **All-Zones** (zone = NULL):
|
||||
- Worker can input to any zone
|
||||
- Example: zone = NULL (uses manager's discretion)
|
||||
|
||||
3. **Unassigned** (no binding):
|
||||
- Worker CANNOT access warehouse module
|
||||
- Gets access denied when trying to visit /warehouse/*
|
||||
|
||||

|
||||
|
||||
## How to Use the System
|
||||
|
||||
### 1. Create a Warehouse Manager
|
||||
|
||||
1. Go to Settings → User Management → Create User
|
||||
2. Fill in user details (username, email, etc.)
|
||||
3. Set **Role** to "Manager - Warehouse (Level 75)"
|
||||
4. Check "Warehouse" under Module Access
|
||||
5. Save user
|
||||
|
||||
### 2. Create a Warehouse Worker
|
||||
|
||||
1. Go to Settings → User Management → Create User
|
||||
2. Fill in user details
|
||||
3. Set **Role** to "Worker - Warehouse (Level 35)"
|
||||
4. Check "Warehouse" under Module Access
|
||||
5. Save user
|
||||
|
||||
### 3. Assign Worker to Manager (with Zone)
|
||||
|
||||
```python
|
||||
# In your Python code:
|
||||
from app.modules.settings.warehouse_worker_management import assign_worker_to_manager
|
||||
|
||||
success, message = assign_worker_to_manager(
|
||||
manager_id=6, # Maria Garcia
|
||||
worker_id=15, # David Chen
|
||||
warehouse_zone="Cold Storage"
|
||||
)
|
||||
|
||||
# Or without zone restriction:
|
||||
success, message = assign_worker_to_manager(
|
||||
manager_id=6,
|
||||
worker_id=12,
|
||||
warehouse_zone=None # Can input to all zones
|
||||
)
|
||||
```
|
||||
|
||||
### 4. Protect Routes with Zone Checks
|
||||
|
||||
```python
|
||||
from flask import session, redirect, url_for
|
||||
from app.access_control import can_access_warehouse_input
|
||||
|
||||
@warehouse_bp.route('/set-boxes-locations', methods=['GET', 'POST'])
|
||||
def set_boxes_locations():
|
||||
if not can_access_warehouse_input(session.get('role')):
|
||||
flash('Access denied', 'error')
|
||||
return redirect(url_for('warehouse.warehouse_index'))
|
||||
|
||||
# ... rest of route
|
||||
```
|
||||
|
||||
### 5. Filter Queries by Zone
|
||||
|
||||
```python
|
||||
from app.access_control import build_zone_filter_sql
|
||||
|
||||
filter_sql = build_zone_filter_sql(user_id, user_role)
|
||||
query = f"SELECT * FROM warehouse_entries WHERE status='active' {filter_sql}"
|
||||
|
||||
# If warehouse_manager ID=6: returns all workers' data + own data
|
||||
# If warehouse_worker ID=15: returns only WHERE created_by_user_id=15
|
||||
# If superadmin: returns all data (no filter)
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Database Queries Reference
|
||||
|
||||
### Get worker's manager and zone
|
||||
```sql
|
||||
SELECT m.id, m.full_name, wmb.warehouse_zone
|
||||
FROM worker_manager_bindings wmb
|
||||
JOIN users m ON wmb.manager_id = m.id
|
||||
WHERE wmb.worker_id = 15 AND wmb.is_active = 1;
|
||||
```
|
||||
|
||||
### Get all workers for a manager
|
||||
```sql
|
||||
SELECT u.id, u.username, u.full_name, wmb.warehouse_zone
|
||||
FROM worker_manager_bindings wmb
|
||||
JOIN users u ON wmb.worker_id = u.id
|
||||
WHERE wmb.manager_id = 6 AND wmb.is_active = 1
|
||||
ORDER BY u.full_name;
|
||||
```
|
||||
|
||||
### Get warehouse data for a manager (all zones)
|
||||
```sql
|
||||
SELECT * FROM warehouse_entries
|
||||
WHERE created_by_user_id IN (
|
||||
SELECT worker_id FROM worker_manager_bindings
|
||||
WHERE manager_id = 6 AND is_active = 1
|
||||
);
|
||||
```
|
||||
|
||||
### Get warehouse data for a worker (their zone only)
|
||||
```sql
|
||||
SELECT * FROM warehouse_entries
|
||||
WHERE created_by_user_id = 15
|
||||
AND warehouse_zone = (
|
||||
SELECT warehouse_zone FROM worker_manager_bindings
|
||||
WHERE worker_id = 15 AND is_active = 1
|
||||
);

||||
- [ ] Add zone filtering to SELECT queries
|
||||
|
||||
### Phase 2: Worker Management UI (High Priority)
|
||||
- [ ] Create `/settings/warehouse-worker-assignment` page
|
||||
- [ ] Add manager-to-worker assignment form
|
||||
- [ ] Show assigned workers list
|
||||
- [ ] Add zone restriction editor
|
||||
- [ ] Implement worker reassignment
|
||||
|
||||

|
||||
|
||||
## Security Checklist
|
||||
|
||||
✅ **Server-Side Validation**
|
||||
- All permission checks happen on server
|
||||
- All zone validations happen in database queries
|
||||
- Frontend filtering cannot bypass restrictions
|
||||
|
||||
✅ **Data Isolation**
|
||||
- Workers only see their own data
|
||||
- Managers only see assigned workers' data
|
||||
- No cross-worker visibility
|
||||
|
||||
✅ **Role Enforcement**
|
||||
- Each role has explicit permissions
|
||||
- Roles cannot cross modules without assignment
|
||||
- Quality and warehouse roles are separate
|
||||
|
||||
✅ **Audit Trail**
|
||||
- worker_manager_bindings tracks all assignments
|
||||
- created_by_user_id tracks who entered data
|
||||
- created_at timestamps all entries
|
||||

|
||||
|
||||
## Deployment Notes
|
||||
|
||||
1. **Database Migration**:
|
||||
```bash
|
||||
# Run database initialization (automatically done by Docker)
|
||||
docker-compose up -d
|
||||
|
||||
# Or manually if needed:
|
||||
mysql -h <host> -u <user> -p <db> < add_warehouse_roles_and_bindings.sql
|
||||
```
|
||||
|
||||
2. **Restart Application**:
|
||||
```bash
|
||||
docker-compose restart
|
||||
```
|
||||
|
||||
3. **Verify Installation**:
|
||||
- Check that warehouse roles appear in user creation form
|
||||
- Create test warehouse_manager and warehouse_worker users
|
||||
- Test role matrix table displays correctly
|
||||
|
||||
4. **Test Access Control**:
|
||||
- Log in as warehouse_manager → should access warehouse module
|
||||
- Log in as warehouse_worker → should access warehouse module but not reports
|
||||
- Verify zone filtering works in warehouse routes
