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:

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

📝 Implementation Details

Database Fields

All new fields added to AnimeSeries model:

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
