Introduced comprehensive test coverage for GiftItem, GiftCategory, and GiftPurchase models to validate core functionality such as creation, updates, deletions, and derived properties. Also updated the `total_gifts` method in `GiftCategory` to calculate the total requested quantity rather than the count of gifts.
Introduce EventMedia for managing media files linked to events, including file metadata, purpose, and relationships. Add GiftCategory to categorize gifts, featuring unique constraints, display options, and utility methods for handling related gifts.
Introduce a new RSVP model to manage responses for events, including status, guest count, and additional details like dietary requirements. Enforce uniqueness for each guest per event and provide functionality to update RSVP status. This will support efficient event RSVP handling and data integrity.
