We are currently solving the following issue within our repository. Here is the issue text:
--- BEGIN ISSUE ---
Hide attendanceevent from django admin
https://online.ntnu.no/admin/events/attendanceevent/

This view should not be used by anyone and attendance info should be edited through the event directly. 

Should be possible to hide this by removing 
`admin.site.register(AttendanceEvent, AttendanceEventAdmin)`
 in events/admin.py (untested)
