# Task 8: Add Database Support for NFO Status - Status Report

## Summary

Task 8 adds database support to track NFO file status for anime series, including creation timestamps and external IDs (TMDB/TVDB).

## ✅ Completed (100%)

### 1. Database Model Updates (100%)

-   ✅ **Updated `src/server/database/models.py`**
    -   Added `has_nfo` (Boolean) - Whether tvshow.nfo exists
    -   Added `nfo_created_at` (DateTime) - When NFO was first created
    -   Added `nfo_updated_at` (DateTime) - When NFO was last updated
    -   Added `tmdb_id` (Integer, indexed) - TMDB database ID
    -   Added `tvdb_id` (Integer, indexed) - TVDB database ID
    -   All fields nullable with proper defaults
    -   SQLAlchemy will auto-create new columns (no manual migration needed)

### 2. Service Layer Updates (100%)

-   ✅ **Updated `src/server/services/anime_service.py`**
    -   Added `update_nfo_status()` method to update NFO tracking
    -   Added `get_series_without_nfo()` method to query series missing NFO
    -   Added `get_nfo_statistics()` method to get NFO statistics
    -   All methods support optional database session parameter
    -   Proper error handling and logging
    -   Comprehensive type hints

### 3. Database Model Tests (100%)

-   ✅ **Updated `tests/unit/test_database_models.py`**
    -   Added 5 new tests for NFO fields in TestAnimeSeries class
    -   Test default values (has_nfo=False, nulls for timestamps)
    -   Test setting NFO field values
    -   Test updating NFO status after creation
    -   Test querying by has_nfo status
    -   Test querying by TMDB ID
    -   All 9 tests in TestAnimeSeries passing

### 4. Service Tests (100%)

-   ✅ **Updated `tests/unit/test_anime_service.py`**
    -   Added TestNFOTracking class with 4 comprehensive tests
    -   Test `update_nfo_status()` success case
    -   Test `update_nfo_status()` when series not found
    -   Test `get_series_without_nfo()` query
    -   Test `get_nfo_statistics()` counts
    -   All tests use proper mocking
    -   All 4 tests passing

### 5. Integration Tests (100%)

-   ✅ **Created `tests/integration/test_nfo_database.py`**
    -   6 comprehensive integration tests
    -   Test creating series with NFO tracking
    -   Test querying series without NFO
    -   Test querying by TMDB ID
    -   Test updating NFO status
    -   Test backward compatibility with existing data
    -   Test statistics queries
    -   All 6 tests passing

## 📊 Test Statistics

-   **Database Model Tests**: 9/9 passing (5 new NFO tests added)
-   **Service Tests**: 4/4 passing (new TestNFOTracking class)
-   **Integration Tests**: 6/6 passing (new test file created)
-   **Total New Tests**: 15 tests added
-   **Total Pass Rate**: 19/19 (100%)

## 🎯 Acceptance Criteria Status

All Task 8 acceptance criteria met:

-   [x] Database schema updated (SQLAlchemy will auto-create columns)
-   [x] NFO status tracked in DB
-   [x] Queries for missing NFOs work
-   [x] Backward compatible with existing data
-   [x] Database tests pass

## 📝 Implementation Details

### Database Fields

All new fields added to `AnimeSeries` model:

```python
has_nfo: bool = False  # Whether tvshow.nfo exists
nfo_created_at: Optional[datetime] = None  # Creation timestamp
nfo_updated_at: Optional[datetime] = None  # Last update timestamp
tmdb_id: Optional[int] = None  # TMDB ID (indexed)
tvdb_id: Optional[int] = None  # TVDB ID (indexed)
```

### Service Methods

Three new methods added to `AnimeService`:

1. **update_nfo_status(key, has_nfo, tmdb_id, tvdb_id, db)**
    - Updates NFO status for a series
    - Sets creation/update timestamps
    - Stores external database IDs

2. **get_series_without_nfo(db)**
    - Returns list of series without NFO files
    - Includes key, name, folder, and IDs
    - Useful for batch operations

3. **get_nfo_statistics(db)**
    - Returns NFO statistics
    - Counts: total, with_nfo, without_nfo, with_tmdb_id, with_tvdb_id
    - Useful for dashboards and reporting

### Backward Compatibility

-   All new fields are nullable with defaults
-   Existing series will have `has_nfo=False` and null timestamps
-   No manual database migration required
-   SQLAlchemy auto-creates columns on first run
-   Queries work with mixed old/new data

### Query Performance

-   Indexed `tmdb_id` and `tvdb_id` for fast lookups
-   Efficient boolean queries on `has_nfo`
-   Statistics queries optimized with proper filters
