From 1cefa437b7964eed2ee42001296274e2ee2dfbf1 Mon Sep 17 00:00:00 2001 From: kikootwo Date: Mon, 22 Dec 2025 14:20:22 -0500 Subject: [PATCH] Add ASIN/ISBN fields to library and improve matching Introduces `asin` and `isbn` fields to the PlexLibrary schema and database, with migration and indexing for fast lookups. Updates scan and recently-added processors to persist ASIN/ISBN from both Plex and Audiobookshelf backends. Enhances matching logic to prioritize exact ASIN matches using the new fields, improving match accuracy for Audiobookshelf users. Also includes minor improvements: fixes cover art handling for cached thumbnails, adds download URL validation in Prowlarr and qBittorrent integrations, and updates documentation to reflect these changes. --- .gitignore | 3 +- documentation/backend/database.md | 13 + documentation/fixes/asin-matching-fix.md | 350 ++++++++++++++++++ documentation/phase3/file-organization.md | 1 + .../migration.sql | 9 + prisma/schema.prisma | 13 +- src/lib/integrations/prowlarr.service.ts | 19 +- src/lib/integrations/qbittorrent.service.ts | 8 +- .../plex-recently-added.processor.ts | 4 + src/lib/processors/scan-plex.processor.ts | 4 + src/lib/utils/audiobook-matcher.ts | 35 +- src/lib/utils/file-organizer.ts | 26 +- 12 files changed, 469 insertions(+), 16 deletions(-) create mode 100644 documentation/fixes/asin-matching-fix.md create mode 100644 prisma/migrations/20251222140111_add_asin_isbn_to_library/migration.sql diff --git a/.gitignore b/.gitignore index 4167627..ed3239e 100644 --- a/.gitignore +++ b/.gitignore @@ -51,4 +51,5 @@ next-env.d.ts /RMAB /cache /redis -/pgdata \ No newline at end of file +/pgdata +/test-media \ No newline at end of file diff --git a/documentation/backend/database.md b/documentation/backend/database.md index b0e1feb..084b321 100644 --- a/documentation/backend/database.md +++ b/documentation/backend/database.md @@ -28,6 +28,19 @@ PostgreSQL database storing users, audiobooks, requests, downloads, configuratio - Indexes: `asin`, `title`, `author`, `is_popular`, `is_new_release`, `popular_rank`, `new_release_rank` - **Purpose:** Cached Audible metadata (popular/new releases), thumbnails stored locally in `/app/cache/thumbnails` +### Plex_Library (Library Cache) +- `id` (UUID PK), `plex_guid` (unique, external ID from Plex or Audiobookshelf), `plex_rating_key` +- `title`, `author`, `narrator`, `summary`, `duration` (milliseconds), `year`, `user_rating` (0-10 scale) +- **Universal identifiers:** `asin` (Audible ASIN), `isbn` (ISBN-10 or ISBN-13) +- `file_path`, `thumb_url`, `plex_library_id`, `added_at` +- `last_scanned_at`, `created_at`, `updated_at` +- Indexes: `plex_guid`, `title`, `author`, `plex_library_id`, `asin`, `isbn` +- **Purpose:** Universal library cache for both Plex and Audiobookshelf backends +- **ASIN/ISBN fields:** Enable accurate matching across backends + - **Plex:** ASIN extracted from Plex GUID (e.g., `com.plexapp.agents.audible://B00ABC123`) + stored in dedicated field + - **Audiobookshelf:** ASIN/ISBN retrieved directly from ABS metadata + stored in dedicated fields + - **Matching:** Prioritizes exact ASIN/ISBN matches (100% confidence) before fuzzy title/author matching + ### Audiobooks - `id` (UUID PK), `audible_asin` (nullable), `title`, `author`, `narrator`, `description` - `cover_art_url`, `file_path`, `file_format`, `file_size_bytes` diff --git a/documentation/fixes/asin-matching-fix.md b/documentation/fixes/asin-matching-fix.md new file mode 100644 index 0000000..abee6cf --- /dev/null +++ b/documentation/fixes/asin-matching-fix.md @@ -0,0 +1,350 @@ +# ASIN Matching Fix for Audiobookshelf + +**Status:** ✅ Implemented (awaiting database migration) +**Date:** 2025-12-22 +**Issue:** ASIN matching failing for Audiobookshelf backend, resulting in fuzzy matches only + +## Problem Statement + +### Root Cause +Audiobookshelf provides rich ASIN metadata for almost every audiobook, but the matching algorithm was failing to use it effectively.
