Implemented a complete shopping cart system with database persistence, replacing the previous stub implementation. The cart now properly stores items across sessions and follows the project's architecture patterns. Database Changes: - Add cart_items table with vendor_id, session_id, product_id, quantity, price_at_add - Create unique constraint to prevent duplicate items per session - Add indexes for session lookups and old cart cleanup - Run migration a2064e1dfcd4 to create cart_items table New Models & Schemas: - models/database/cart.py: CartItem SQLAlchemy model with relationships - models/schema/cart.py: Pydantic schemas for requests/responses * AddToCartRequest, UpdateCartItemRequest * CartResponse, CartItemResponse, CartOperationResponse, ClearCartResponse Exception Handling: - app/exceptions/cart.py: Cart-specific exceptions following project patterns * CartItemNotFoundException - item not found in cart * InsufficientInventoryForCartException - not enough inventory for cart operation * InvalidCartQuantityException - invalid quantity validation * CartValidationException - general cart validation * EmptyCartException - operations on empty cart * ProductNotAvailableForCartException - product unavailable - Updated app/exceptions/__init__.py to export cart exceptions Service Layer: - Implement cart_service.get_cart() - fetch cart from database with totals - Implement cart_service.add_to_cart() - create or update cart items with inventory checks - Implement cart_service.update_cart_item() - update quantity with validation - Implement cart_service.remove_from_cart() - delete cart item - Implement cart_service.clear_cart() - remove all items for session - Replace generic exceptions with cart-specific ones - Fix InsufficientInventoryException usage (was using wrong parameters) API Layer: - Update app/api/v1/shop/cart.py to use Pydantic schemas - Add response_model declarations to all endpoints - Add return type hints for type safety - Convert service dict responses to Pydantic models Features: - Cart items persist in database across server restarts - Inventory validation before adding/updating items - Price captured at time of adding to cart - Duplicate items update quantity instead of creating new entries - Full CRUD operations with proper error handling - Type-safe API with auto-generated OpenAPI documentation 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
