Route deletion failed with two integrity errors: 1. route_encounters had no cascade, so SQLAlchemy tried to NULL the non-nullable route_id instead of deleting the rows 2. boss_battles.after_route_id referenced the route being deleted Added cascade="all, delete-orphan" to Route.route_encounters and nulled out boss battle after_route_id references before deletion.

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 |
