Updated the backend services and handlers to properly detect and pass
the has_cover parameter's validity state to the database layer.
Changes:
- services/search.go: Changed HasCover type from bool to pgtype.Bool
to support 3-state logic (NULL, TRUE, FALSE)
- handlers/media.go: Fixed 3-state detection by checking if has_cover
exists in query params before setting Valid flag
- router/search.go: Fixed 3-state detection to match media.go logic
- router/frontend.go: Use pgtype.Bool{Valid: false} for SSR initial
load to ensure no filtering occurs on first page load
The key fix is detecting whether the has_cover parameter was actually
sent in the request:
- Parameter not sent → pgtype.Bool{Bool: false, Valid: false}
- Parameter sent as "true" → pgtype.Bool{Bool: true, Valid: true}
- Parameter sent as "false" → pgtype.Bool{Bool: false, Valid: true}
Previously, media.go was hardcoding Valid: true, which meant it was
always filtering by has_cover=false (only books without covers) when
the parameter wasn't sent, causing searches to incorrectly return
0 results for queries like "1984".
This ensures consistency between the JSON API endpoint (media.go) and
the HTML endpoint (search.go), and fixes the critical bug where SSR
was returning 0 books on initial page load.
Rewrite /api/media-items/search endpoint to detect HTMX requests and return appropriate response format. The endpoint now checks for HX-Request header and routes to HTML renderer or JSON handler accordingly.
- Check HX-Request header to detect HTMX requests
- Return HTML via BooksGrid template for HTMX requests
- Return JSON for API clients (existing behavior)
- Add handleSearchHTML function for HTML rendering
- Use shared MediaHandler.ExecuteSearch method
- Eliminates previous issue where JSON was rendered in browser
- Update Config struct to replace EbookHandler with MediaHandler, SearchHandler, MatchingHandler
- Add CollectionHandler to Config struct
- Update RegisterRoutes to call new registration functions
- Create registerCollectionsRoutes for 15 collection endpoints
- Create registerSearchRoutes for search endpoints (uses MediaHandler.SearchMediaItems, MatchingHandler.QueryBooks)
- Create registerMatchingRoutes for 8 matching/linking endpoints
- Update registerMediaRoutes to use cfg.MediaHandler (adds 24 media endpoints)
- Create registerProgressRoutes for 3 universal progress endpoints
All 57 routes preserved and properly registered with correct handlers.
No functionality lost, all endpoints work identically.
This is Phase 5 of the ebook.go refactoring plan.
