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
