Add database schema and SQL queries for generic saved filters system
that allows users to save custom filter presets for any resource type.
Database Schema:
- Add saved_filters table with user_id, name, resource_type, filters (JSONB)
- Create composite index on (user_id, resource_type) for efficient lookups
- Create index on (user_id, name) for future name search feature
- Add update_updated_at_column() trigger to auto-update timestamps
- Make trigger creation idempotent with DROP TRIGGER IF EXISTS
SQL Queries (5 new queries):
- GetSavedFilters: List all filters for user + resource type
- GetSavedFilterByID: Retrieve single filter by ID
- CreateSavedFilter: Create new saved filter
- UpdateSavedFilter: Update filter name/criteria
- DeleteSavedFilter: Remove saved filter
Design Decisions:
- Generic resource_type field supports any resource (media-items, collections, devices)
- JSONB filters field allows flexible schema without migrations
- User-scoped via JWT (user_id foreign key with CASCADE delete)
- Automatic updated_at timestamp via database trigger
Generated Code:
- database.SavedFilters model (10 fields including JSONB filters)
- All 5 CRUD query functions with proper parameter types
- pgtype.UUID wrappers for UUID parameters
