# Default Asset Task Creation Implementation
## Overview
This document describes the implementation of automatic default task creation for assets based on their category (Task 5.3).
## Requirements Implemented
- **17.1**: Automatic task generation when assets are created based on asset category
- **17.2**: Default task templates for each asset category (modeling, surfacing, rigging)
- **17.3**: Customizable task creation options for coordinators
- **17.4**: Default task naming conventions
- **17.5**: API endpoint for retrieving default tasks by asset category
- **17.6**: Proper task naming
- **17.7**: Unassigned task creation
## Backend Implementation
### Default Task Templates
Located in `backend/routers/assets.py`:
```python
DEFAULT_ASSET_TASKS = {
AssetCategory.CHARACTERS: ["modeling", "surfacing", "rigging"],
AssetCategory.PROPS: ["modeling", "surfacing"],
AssetCategory.SETS: ["modeling", "surfacing"],
AssetCategory.VEHICLES: ["modeling", "surfacing", "rigging"]
}
```
### Key Functions
#### `get_default_asset_task_types(category: AssetCategory) -> List[str]`
Returns the default task types for a given asset category.
#### `get_all_asset_task_types(project_id: int, db: Session) -> List[str]`
Returns all task types (standard + custom) for assets in a project.
#### `create_default_tasks_for_asset(asset: Asset, task_types: List[str], db: Session) -> List[Task]`
Creates default tasks for an asset with proper naming conventions:
- Task name format: `{asset_name} - {task_type.title()}`
- Tasks are created with status `NOT_STARTED`
- Tasks are left unassigned (assigned_user_id = None)
### API Endpoints
#### `GET /assets/default-tasks/{category}`
Returns default task types for an asset category.
**Query Parameters:**
- `project_id` (optional): Include custom task types for the project
**Response:**
```json
["modeling", "surfacing", "rigging"]
```
#### `POST /assets/?project_id={project_id}`
Creates a new asset with optional default tasks.
**Request Body:**
```json
{
"name": "Hero Character",
"category": "characters",
"description": "Main character asset",
"status": "not_started",
"create_default_tasks": true,
"selected_task_types": ["modeling", "surfacing", "rigging"]
}
```
**Fields:**
- `create_default_tasks` (boolean): Whether to create default tasks (default: true)
- `selected_task_types` (array, optional): Specific task types to create. If not provided, uses category defaults.
**Response:**
```json
{
"id": 1,
"name": "Hero Character",
"category": "characters",
"status": "not_started",
"project_id": 1,
"task_count": 3,
"created_at": "2024-01-01T00:00:00Z",
"updated_at": "2024-01-01T00:00:00Z"
}
```
## Frontend Implementation
### AssetForm Component
Located in `frontend/src/components/asset/AssetForm.vue`
**Features:**
1. **Default Tasks Toggle**: Checkbox to enable/disable default task creation
2. **Task Preview**: Shows which tasks will be created based on category
3. **Custom Task Selection**: Allows coordinators to select specific tasks to create
4. **Confirmation Dialog**: Shows preview of tasks before creation
**Key Sections:**
```vue
<!-- Default Tasks Section -->
<div v-if="!isEdit" class="space-y-4 border-t pt-4">
<div class="flex items-center space-x-2">
<Checkbox
id="create-default-tasks"
v-model:checked="formData.create_default_tasks"
/>
<Label>Create default tasks for this asset</Label>
</div>
<!-- Task Selection -->
<div v-if="formData.create_default_tasks && formData.category">
<div v-for="taskType in defaultTasks" :key="taskType">
<Checkbox
:checked="selectedTaskTypes.includes(taskType)"
@update:checked="toggleTaskType(taskType)"
/>
<Label>{{ formatTaskType(taskType) }}</Label>
</div>
</div>
</div>
```
### Asset Service
Located in `frontend/src/services/asset.ts`
**Methods:**
```typescript
async getDefaultTasksForCategory(
category: AssetCategory,
projectId?: number
): Promise<string[]>
async createAsset(
projectId: number,
data: AssetCreate
): Promise<Asset>
```
## Task Naming Convention
Tasks are automatically named using the format:
```
{Asset Name} - {Task Type}
```
Examples:
- "Hero Character - Modeling"
- "Hero Character - Surfacing"
- "Hero Character - Rigging"
- "Sword Prop - Modeling"
- "Sword Prop - Surfacing"
## Task Assignment
All default tasks are created **unassigned** (assigned_user_id = null). Coordinators must manually assign tasks to artists after creation.
## Category-Specific Defaults
| Category | Default Tasks |
|------------|-----------------------------------|
| Characters | Modeling, Surfacing, Rigging |
| Props | Modeling, Surfacing |
| Sets | Modeling, Surfacing |
| Vehicles | Modeling, Surfacing, Rigging |
## Custom Task Types
The system supports custom task types per project. When a project has custom asset task types defined, they are included in the available task types for selection during asset creation.
## Testing
### Backend Test
Run `backend/test_default_asset_tasks.py` to verify:
- Default task templates for each category
- Asset creation with default tasks
- Task naming conventions
- Custom task selection
- Unassigned task creation
### Frontend Test
Open `frontend/test-default-asset-tasks.html` to test:
- Default task retrieval
- Asset creation with task selection
- Task verification
## Usage Example
### Creating an Asset with Default Tasks
1. Navigate to Assets section in a project
2. Click "Create Asset"
3. Fill in asset details (name, category, description)
4. Ensure "Create default tasks" is checked
5. Review the task preview
6. Optionally customize which tasks to create
7. Click "Create Asset"
8. Confirm task creation in the dialog
### Creating an Asset without Default Tasks
1. Follow steps 1-3 above
2. Uncheck "Create default tasks"
3. Click "Create Asset"
4. Asset is created with no tasks
### Custom Task Selection
1. Follow steps 1-4 above
2. Uncheck specific tasks you don't want to create
3. Click "Create Asset"
4. Only selected tasks will be created
## Integration with Custom Task Types
When custom task types are defined for a project (via Task 19), they are automatically included in the available task types for asset creation. The default task templates remain the same, but coordinators can select custom task types during asset creation.
## Error Handling
- Validates that selected task types are valid (standard or custom)
- Prevents duplicate asset names within a project
- Returns appropriate error messages for invalid requests
- Handles missing project or category gracefully
## Performance Considerations
- Tasks are created in a single database transaction
- Bulk task creation is efficient using SQLAlchemy's bulk operations
- Task count is returned immediately after creation without additional queries
