Fix NFO database query errors

- Fixed async context manager issue in anime.py (use get_sync_session)
- Fixed async methods in anime_service.py to use async with
- Fixed folder_name attribute error (should be folder)
- All three methods now properly handle database sessions

 ## TODO List:
 
-### 🎯 Priority: NFO FSK Rating Implementation ✅ COMPLETED
+All tasks completed! The NFO database query issue has been resolved.
 
-**Task: Implement German FSK Rating Support in NFO Files**
+## Recently Fixed Issues:
 
-**Status: COMPLETED** ✅
+### ✅ Fixed: NFO Database Query Error (2026-01-18)
 
-**Implementation Summary:**
+**Issue:** WARNING: Could not fetch NFO data from database: '\_AsyncGeneratorContextManager' object has no attribute 'query'
 
-All requirements have been successfully implemented and tested:
+**Root Cause:**
 
-1. ✅ **TMDB API Integration**: Added `get_tv_show_content_ratings()` method to TMDBClient
+1. Synchronous code in `anime.py` was calling `get_db_session()` which returns an async context manager, but wasn't using `async with`.
-2. ✅ **Data Model**: Added optional `fsk` field to `TVShowNFO` model
+2. Async methods in `anime_service.py` were calling `get_db_session()` without using `async with`.
-3. ✅ **FSK Extraction**: Implemented `_extract_fsk_rating()` method in NFOService with comprehensive mapping:
+3. Incorrect attribute name: used `folder_name` instead of `folder`.
-    - Maps TMDB German ratings (0, 6, 12, 16, 18) to FSK format
+
-    - Handles already formatted FSK strings
+**Solution:**
-    - Supports partial matches (e.g., "Ab 16 Jahren" → "FSK 16")
+
-    - Fallback to None when German rating unavailable
+1. Changed `anime.py` line ~323 to use `get_sync_session()` instead of `get_db_session()` for synchronous database access.
-4. ✅ **XML Generation**: Updated `generate_tvshow_nfo()` to prefer FSK over MPAA when available
+2. Updated three async methods in `anime_service.py` to properly use `async with get_db_session()`:
-5. ✅ **Configuration**: Added `nfo_prefer_fsk_rating` setting (default: True)
+    - `update_nfo_status()`
-6. ✅ **Comprehensive Testing**: Added 31 new tests across test_nfo_service.py and test_nfo_generator.py
+    - `get_series_without_nfo()`
-    - All 112 NFO-related tests passing
+    - `get_nfo_statistics()`
-    - Test coverage includes FSK extraction, XML generation, edge cases, and integration
+3. Fixed attribute name from `db_series.folder_name` to `db_series.folder` in `anime.py`.
 
 **Files Modified:**
 
-- `src/core/entities/nfo_models.py` - Added `fsk` field
+- [src/server/api/anime.py](../src/server/api/anime.py)
-- `src/core/services/nfo_service.py` - Added FSK extraction and TMDB API call
+- [src/server/services/anime_service.py](../src/server/services/anime_service.py)
-- `src/core/services/tmdb_client.py` - Added content ratings endpoint
-- `src/core/utils/nfo_generator.py` - Updated XML generation to prefer FSK
-- `src/config/settings.py` - Added `nfo_prefer_fsk_rating` setting
 
-**Files Created:**
+**Verification:** Server now starts without warnings, and NFO metadata can be fetched from the database correctly.
-
-- `tests/unit/test_nfo_service.py` - 23 comprehensive unit tests
-
-**Files Updated:**
-
-- `tests/unit/test_nfo_generator.py` - Added 5 FSK-specific tests
-
-**Acceptance Criteria Met:**
-
-- ✅ NFO files contain FSK rating when available from TMDB
-- ✅ Fallback to MPAA rating if FSK not available
-- ✅ Configuration setting to prefer FSK over MPAA
-- ✅ Unit tests cover all FSK values and fallback scenarios
-- ✅ Existing NFO functionality remains unchanged
-- ✅ Documentation updated with FSK support details

-### 🧪 Priority: Comprehensive NFO and Image Download Tests ✅ COMPLETED
-
-**Task: Add Comprehensive Tests for NFO Creation and Media Downloads**
-
-**Status: COMPLETED** ✅
-
-**Implementation Summary:**
-
-Significantly expanded test coverage for NFO functionality with comprehensive unit and integration tests:
-
-1. ✅ **Unit Tests Expanded** ([test_nfo_service.py](tests/unit/test_nfo_service.py)):
-    - Added 13 tests for media file downloads (poster, logo, fanart)
-    - Tests for various image sizes and configurations
-    - Tests for download failures and edge cases
-    - Configuration testing for NFO service settings
-    - **Total: 44 tests** in test_nfo_service.py
-
-2. ✅ **Integration Tests Created** ([test_nfo_integration.py](tests/integration/test_nfo_integration.py)):
-    - Complete NFO creation workflow with all media files
-    - NFO creation without media downloads
-    - Correct folder structure verification
-    - NFO update workflow with media re-download
-    - Error handling and recovery
-    - Concurrent NFO operations (batch creation)
-    - Data integrity validation
-    - **Total: 10 comprehensive integration tests**
-
-3. ✅ **API Endpoint Tests**: Existing test_nfo_endpoints.py already covers all NFO API endpoints
-
-**Files Modified:**
-
-- `tests/unit/test_nfo_service.py` - Added 23 new tests for media downloads and configuration
-
-**Files Created:**
-
-- `tests/integration/test_nfo_integration.py` - 10 comprehensive integration tests
-
-**Test Results:**
-
-- ✅ **44 tests passing** in test_nfo_service.py (unit)
-- ✅ **10 tests passing** in test_nfo_integration.py (integration)
-- ✅ **112 total NFO-related unit tests passing**
-- ✅ **All tests verify**:
-    - FSK rating extraction and mapping
-    - Media file download scenarios
-    - NFO creation and update workflows
-    - Error handling and edge cases
-    - Concurrent operations
-    - Data integrity
-
-**Acceptance Criteria Met:**
-
-- ✅ Comprehensive unit tests for all media download scenarios
-- ✅ Integration tests verify complete workflows
-- ✅ Tests validate file system state after operations
-- ✅ Edge cases and error scenarios covered
-- ✅ Concurrent operations tested
-- ✅ All tests use proper mocking for TMDB API
-- ✅ Test fixtures provide realistic test data
-
-**Test Coverage Highlights:**
-
-- Media download with all combinations (poster/logo/fanart)
-- Different image sizes (original, w500, w780, w342)
-- Missing media scenarios
-- Concurrent NFO creation
-- NFO update workflows
-- FSK rating preservation
-- Complete metadata integrity
