"""
Full-featured Rides API views for ThrillWiki API v1.

This module implements a "full fat" set of endpoints:
- List / Create: GET /rides/  POST /rides/
- Retrieve / Update / Delete: GET /rides/{pk}/  PATCH/PUT/DELETE
- Filter options: GET /rides/filter-options/
- Company search: GET /rides/search/companies/?q=...
- Ride model search: GET /rides/search-ride-models/?q=...
- Search suggestions: GET /rides/search-suggestions/?q=...
Notes:
- These views try to use real Django models if available. If the domain models/services
  are not present, they return a clear 501 response explaining what to wire up.
