Mon, 2 Mar 2026 18:12:01 +0100 Subject: [PATCH 05/47] feat(services): add complete CRUD API for item management Implement full e-commerce item management service following OpenTaberna mini-API architecture pattern. - 6 RESTful CRUD endpoints with proper HTTP semantics - Repository pattern with specialized queries - UUID primary keys with automatic timestamps - PostgreSQL JSONB for flexible nested data - Comprehensive validation and error handling - \`POST /api/v1/items/\` - Create item (201) - \`GET /api/v1/items/{uuid}\` - Get by UUID (200/404) - \`GET /api/v1/items/\` - List with pagination (200) - \`GET /api/v1/items/by-slug/{slug}\` - Get by slug (200/404) - \`PATCH /api/v1/items/{uuid}\` - Update item (200/404/400) - \`DELETE /api/v1/items/{uuid}\` - Delete item (204/404) - 9 enums (ItemStatus, StockStatus, TaxClass, etc.) - 8 nested models (PriceModel, MediaModel, InventoryModel, etc.) - Pydantic v2 with ConfigDict for validation - SQLAlchemy async ORM with indexed columns - Duplicate SKU/slug validation with 400 responses - Pagination with configurable skip/limit - Status-based filtering - JSONB storage for attributes, identifiers, custom data - Async/await for non-blocking I/O - Proper dependency injection with get_session_dependency BREAKING CHANGE: Renames service directory from crud-item-store to crud_item_store (Python naming convention) ---
