🐛 Database Fixes:
- Added unique constraint on user_cards (user_id, card_id)
- Added unique constraint on collection_cards (collection_id, card_id)
- Fixed ON CONFLICT clauses in card ownership API
✨ Auto-Sync Feature:
- Card ownership now automatically syncs with 'All My Cards' collection
- When user marks card as owned → added to system collection
- When user removes ownership → removed from system collection
- Real-time bidirectional sync between user_cards and collection_cards
🔄 Migration Script:
- Cleaned up any duplicate entries
- Added necessary database constraints
- Synced existing owned cards (0 users had existing data)
🎯 API Improvements:
- Simplified card ownership API (removed GET method)
- Better error handling and validation
- Clear success messages for user feedback
- Automatic collection management
Card ownership should now work perfectly! 🚀
✅ Authentication Headers Added:
- Added JWT tokens to all API calls in card detail page
- Fixed collections, decks, ownership, and favorites API calls
- Added proper error handling for authentication failures
🔧 Enhanced Ownership API:
- Added GET method to fetch user's card ownership
- Maintains existing POST method for updating ownership
- Returns user-specific quantity data
🎯 User Data Integration:
- Fetches user's owned quantity on page load
- Checks favorite status from user_favorites table
- Refreshes data after collection/deck additions
- All data now properly scoped to authenticated user
🛡️ Security Improvements:
- All API calls now include Authorization headers
- User-specific data fetching implemented
- No more reliance on global card data
- Proper JWT token validation throughout
The card detail page now properly integrates with the secured API endpoints and displays user-specific data correctly! 🃏🔒
🚨 Fixed Major Data Leakage Issues:
- Replaced hardcoded user_id = 1 with proper JWT authentication
- Fixed collections API to filter by authenticated user
- Fixed card ownership to use user_cards table (not global cards table)
- Fixed decks API to return only user-owned decks
- Fixed card collections/decks APIs to respect user permissions
- Fixed favorites API to use user_favorites table
🛡️ Authentication & Authorization:
- All endpoints now require valid JWT tokens
- Proper user isolation across all data operations
- Collection permissions properly enforced
- User-specific data queries implemented
🔧 Database Schema Fixes:
- Card ownership now uses user_cards table
- Favorites use user_favorites table
- Decks filtered by user_id
- Collections respect ownership and permissions
⚠️ Development Note:
- Added warning for fallback authentication in dev mode
- Should be removed in production deployment
✅ Data Privacy Secured:
- Users can only see their own collections, decks, and owned cards
- Public collections visible to all (as intended)
- Shared collections respect permission levels
- No cross-user data leakage
- Updated card detail page to fetch real data from API
- Added ownership tracking with quantity management
- Added favorite system for cards
- Added collection and deck management functionality
- Created API endpoints for ownership, favorites, collections, and decks
- Added database columns for quantity and favorited status
- Shows current collections and decks the card belongs to
- Added proper error handling and loading states
- Integrated with real card data from database
- Added purchase links to TCGPlayer and eBay
