PROBLEM ANALYSIS: - SQL script created orders bypassing Django ORM - Django signals (post_save) didn't trigger - No reservations were created automatically - Found 51 orders with 102 items and 0 reservations SOLUTION IMPLEMENTED: 1. Updated create_demo_orders command: - Added clear documentation about ORM usage - Already uses ORM (.save()) which triggers signals - Added informative messages about automatic reservations 2. Created fix_missing_reservations command: - Finds OrderItems without reservations - Creates missing Reservation records - Supports --dry-run mode for safety - Handles missing warehouses gracefully 3. Created SQL fix script: - Direct SQL approach for existing data - Creates reservations for all 102 items - Status: 'reserved' - Verified: All items now have reservations 4. Added verification scripts: - check_orders.py: Shows orders/items/reservations count - run_fix_reservations.py: Executes SQL fix RESULTS: - ✓ 102 reservations created for existing orders - ✓ Future orders will use ORM and create reservations automatically - ✓ System now works correctly 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
