# Task 5 Implementation Verification
|
|
|
|
## Task: Backend - Implement PUT endpoint for updating custom status
|
|
|
|
**Status:** ✅ COMPLETED
|
|
|
|
## Requirements Verification
|
|
|
|
### Requirement 2.1: Support updating name
|
|
✅ **IMPLEMENTED**
|
|
- Location: `backend/routers/projects.py` lines 1565-1593
|
|
- The endpoint accepts an optional `name` field in the request body
|
|
- Updates the status name when provided
|
|
- Validates name uniqueness before updating
|
|
|
|
### Requirement 2.2: Support updating color
|
|
✅ **IMPLEMENTED**
|
|
- Location: `backend/routers/projects.py` lines 1595-1597
|
|
- The endpoint accepts an optional `color` field in the request body
|
|
- Updates the status color when provided
|
|
- Color format validation is handled by the `CustomTaskStatusUpdate` schema
|
|
|
|
### Requirement 2.3: Support updating is_default flag
|
|
✅ **IMPLEMENTED**
|
|
- Location: `backend/routers/projects.py` lines 1599-1611
|
|
- The endpoint accepts an optional `is_default` field in the request body
|
|
- Updates the default status flag when provided
|
|
- Handles both setting and unsetting the default flag
|
|
|
|
### Requirement 5.2: If setting as default, unset other default statuses
|
|
✅ **IMPLEMENTED**
|
|
- Location: `backend/routers/projects.py` lines 1601-1607
|
|
- When `is_default` is set to `True`, the endpoint automatically unsets all other default statuses
|
|
- Ensures only one default status exists at a time
|
|
- This is done by iterating through all custom statuses and setting their `is_default` to `False` before setting the current status as default
|
|
|
|
### Additional Requirement: Validate name uniqueness if name is changed
|
|
✅ **IMPLEMENTED**
|
|
- Location: `backend/routers/projects.py` lines 1565-1593
|
|
- Validates that the new name doesn't conflict with:
|
|
- Other custom statuses in the same project
|
|
- System status names
|
|
- Returns 409 Conflict error if name already exists
|
|
|
|
### Additional Requirement: Use flag_modified for JSON column updates
|
|
✅ **IMPLEMENTED**
|
|
- Location: `backend/routers/projects.py` line 1617
|
|
- Uses `flag_modified(db_project, 'custom_task_statuses')` to ensure SQLAlchemy detects changes to the JSON column
|
|
- This is critical for proper database persistence of JSON column updates
|
|
|
|
## Implementation Details
|
|
|
|
### Endpoint Signature
|
|
```python
|
|
@router.put("/{project_id}/task-statuses/{status_id}")
|
|
async def update_custom_task_status(
|
|
project_id: int,
|
|
status_id: str,
|
|
status_update: dict,
|
|
db: Session = Depends(get_db),
|
|
current_user: User = Depends(require_coordinator_or_admin)
|
|
)
|
|
```
|
|
|
|
### Request Body Schema
|
|
Uses `CustomTaskStatusUpdate` from `backend/schemas/custom_task_status.py`:
|
|
```python
|
|
{
|
|
"name": "string (optional)", # 1-50 characters
|
|
"color": "string (optional)", # Hex color code (e.g., #FF5733)
|
|
"is_default": "boolean (optional)" # Set as default status
|
|
}
|
|
```
|
|
|
|
### Response Schema
|
|
Returns `CustomTaskStatusResponse`:
|
|
```python
|
|
{
|
|
"message": "string",
|
|
"status": {
|
|
"id": "string",
|
|
"name": "string",
|
|
"color": "string",
|
|
"order": "integer",
|
|
"is_default": "boolean"
|
|
},
|
|
"all_statuses": {
|
|
"statuses": [...], # All custom statuses
|
|
"system_statuses": [...], # System statuses
|
|
"default_status_id": "string"
|
|
}
|
|
}
|
|
```
|
|
|
|
## Key Features
|
|
|
|
1. **Partial Updates**: All fields are optional, allowing partial updates
|
|
2. **Name Uniqueness Validation**: Prevents duplicate names within a project
|
|
3. **System Status Protection**: Prevents using system status names
|
|
4. **Default Status Management**: Automatically manages default status uniqueness
|
|
5. **JSON Column Handling**: Properly uses `flag_modified` for database persistence
|
|
6. **Authorization**: Requires coordinator or admin role
|
|
7. **Comprehensive Error Handling**: Returns appropriate HTTP status codes
|
|
|
|
## Error Responses
|
|
|
|
- **404 Not Found**: Project or status doesn't exist
|
|
- **409 Conflict**: Name already exists or conflicts with system status
|
|
- **403 Forbidden**: User lacks coordinator/admin permissions
|
|
- **422 Unprocessable Entity**: Invalid request body format
|
|
|
|
## Testing
|
|
|
|
Comprehensive test suite exists at `backend/test_update_custom_task_status.py` covering:
|
|
- ✅ Status name update
|
|
- ✅ Status color update
|
|
- ✅ Both name and color update
|
|
- ✅ Name uniqueness validation
|
|
- ✅ System status name conflict detection
|
|
- ✅ Setting status as default
|
|
- ✅ Changing default status (unsets previous default)
|
|
- ✅ Unsetting default status
|
|
- ✅ Non-existent status handling
|
|
- ✅ JSON column persistence verification
|
|
|
