- Created RideModel model for manufacturer's ride models with specifications
- Created Park model with location, dates, operator, and cached statistics
- Created Ride model with comprehensive stats, manufacturer, and park relationship
- Created Photo model with CloudFlare Images integration and generic relations
- Added lifecycle hooks for auto-slug generation and count updates
- Created migrations and applied to database
- Registered all models in Django admin with detailed fieldsets
- Fixed admin autocomplete_fields to use raw_id_fields where needed
