NetBox Version

v3.7.0

Python Version

Steps to Reproduce

1. Create a Script
2. Create a EventRule linked with the created Script
3. Delete the Script
4. Try to open the EventRule

Expected Behavior

The Script deletion cascades the deletion of the EventRule

Observed Behavior

<class 'django.urls.exceptions.NoReverseMatch'>

Reverse for 'script' with keyword arguments '{'module': '', 'name': 'EventRule'}' not found. 1 pattern(s) tried: ['extras/scripts/(?P<module>[^/]+)/(?P<name>[^/]+)/\\Z']

The user can't manually delete the EventRule either, it trows the error:

'NoneType' object has no attribute 'scripts'

Python version: 3.10.13
NetBox version: 3.7.0
