# Task 5: NFO Management API Endpoints - Status Report

## Summary

Task 5 creates REST API endpoints for NFO management, allowing frontend and external clients to check, create, update, and manage tvshow.nfo files and media.

## ✅ Completed (85%)

### 1. NFO Request/Response Models (100%)

-   ✅ **Created `src/server/models/nfo.py`** (358 lines)
    -   `MediaFilesStatus` - Status of poster/logo/fanart files
    -   `NFOCheckResponse` - Response for NFO existence check
    -   `NFOCreateRequest` - Request to create NFO with options
    -   `NFOCreateResponse` - Response after NFO creation
    -   `NFOContentResponse` - Response with NFO XML content
    -   `MediaDownloadRequest` - Request to download specific media
    -   `NFOBatchCreateRequest` - Batch create multiple NFOs
    -   `NFOBatchResult` - Result for single series in batch
    -   `NFOBatchCreateResponse` - Response after batch operation
    -   `NFOMissingSeries` - Info about series missing NFO
    -   `NFOMissingResponse` - Response listing series without NFOs
    -   All models use Pydantic with comprehensive field descriptions

### 2. NFO API Router (100% created, needs refactoring)

-   ✅ **Created `src/server/api/nfo.py`** (688 lines)
    -   `GET /api/nfo/{serie_id}/check` - Check NFO and media status
    -   `POST /api/nfo/{serie_id}/create` - Create NFO and download media
    -   `PUT /api/nfo/{serie_id}/update` - Update existing NFO
    -   `GET /api/nfo/{serie_id}/content` - Get NFO XML content
    -   `GET /api/nfo/{serie_id}/media/status` - Get media file status
    -   `POST /api/nfo/{serie_id}/media/download` - Download media files
    -   `POST /api/nfo/batch/create` - Batch create NFOs
    -   `GET /api/nfo/missing` - List series without NFOs
    -   All endpoints require authentication
    -   Comprehensive error handling
    -   Input validation via Pydantic
    -   NFO service dependency injection
    
-   ⚠️ **Needs Refactoring:**
    -   Currently uses `anime_service.get_series_list()` pattern
    -   Should use `series_app.list.GetList()` pattern (existing codebase pattern)
    -   Dependency should be `series_app: SeriesApp = Depends(get_series_app)`
    -   All 8 endpoints need to be updated to use series_app

### 3. FastAPI Integration (100%)

-   ✅ **Updated `src/server/fastapi_app.py`**
    -   Imported nfo_router
    -   Registered router with `app.include_router(nfo_router)`
    -   NFO endpoints now available at `/api/nfo/*`

### 4. API Tests (Created, needs updating)

-   ✅ **Created `tests/api/test_nfo_endpoints.py`** (506 lines)
    -   18 comprehensive test cases
    -   Tests for all endpoints
    -   Authentication tests
    -   Success and error cases
    -   Mocking strategy in place
    
-   ⚠️ **Tests Currently Failing:**
    -   17/18 tests failing due to dependency pattern mismatch
    -   1/18 passing (service unavailable test)
    -   Tests mock `anime_service` but should mock `series_app`
    -   Need to update all test fixtures and mocks

## ⚠️ Remaining Work (15%)

### 1. Refactor NFO API Endpoints (High Priority)

**What needs to be done:**
-   Update all 8 endpoints to use `series_app` dependency instead of `anime_service`
-   Change `anime_service.get_series_list()` to `series_app.list.GetList()`
-   Update dependency signatures in all endpoint functions
-   Verify error handling still works correctly

**Example Change:**
```python
# BEFORE:
async def check_nfo(
    serie_id: str,
    _auth: dict = Depends(require_auth),
    anime_service: AnimeService = Depends(get_anime_service),
    nfo_service: NFOService = Depends(get_nfo_service)
):
    series_list = anime_service.get_series_list()

# AFTER:
async def check_nfo(
    serie_id: str,
    _auth: dict = Depends(require_auth),
    series_app: SeriesApp = Depends(get_series_app),
    nfo_service: NFOService = Depends(get_nfo_service)
):
    series_list = series_app.list.GetList()
```

### 2. Update API Tests (High Priority)

**What needs to be done:**
-   Update test fixtures to mock `series_app` instead of `anime_service`
-   Update dependency overrides in tests
-   Verify all 18 tests pass
-   Add any missing edge case tests

**Example Change:**
```python
# BEFORE:
@pytest.fixture
def mock_anime_service():
    service = Mock()
    service.get_series_list = Mock(return_value=[serie])
    return service

# AFTER:
@pytest.fixture
def mock_series_app():
    app = Mock()
    list_mock = Mock()
    list_mock.GetList = Mock(return_value=[serie])
    app.list = list_mock
    return app
```

### 3. Documentation (Not Started)

**What needs to be done:**
-   Update `docs/API.md` with NFO endpoint documentation
-   Add endpoint examples and request/response formats
-   Document authentication requirements
-   Document error responses

## 📊 Test Statistics

-   **Models**: 11 Pydantic models created
-   **Endpoints**: 8 REST API endpoints implemented
-   **Test Cases**: 18 comprehensive tests written
-   **Current Pass Rate**: 1/18 (5.5%)
-   **Expected Pass Rate after Refactor**: 18/18 (100%)

### Error Handling

All endpoints handle:
- 401 Unauthorized (no auth token)
- 404 Not Found (series/NFO not found)
- 409 Conflict (NFO already exists on create)
- 503 Service Unavailable (TMDB API key not configured)
- 500 Internal Server Error (unexpected errors)

### Dependency Injection

- `require_auth` - Ensures authentication
- `get_nfo_service` - Provides NFOService instance
- `get_series_app` - Should provide SeriesApp instance (needs updating)

## 🔄 Code Quality

-   **Type Hints**: Comprehensive type annotations throughout
-   **Error Handling**: Try/catch blocks in all endpoints
-   **Logging**: Error logging with exc_info=True
-   **Validation**: Pydantic models for all requests/responses
-   **Code Style**: Following project conventions (minor lint issues remain)
