Deleting a route returns 500 due to two FK constraint issues:
|
||
|
|
|
||
|
|
1. `route_encounters.route_id` — missing cascade on the relationship (SQLAlchemy tried to NULL a NOT NULL column)
|
||
|
|
2. `boss_battles.after_route_id` — references the route being deleted
|
||
|
|
|
||
|
|
## Fix
|
||
|
|
- Added `cascade="all, delete-orphan"` to `Route.route_encounters` relationship
|
||
|
|
- Added `update(BossBattle).where(...).values(after_route_id=None)` before deleting the route in the delete endpoint
