Reversion does not work as expected
I tried to revert an Untis import (done using AlekSIS-App-Untis).
I got the revision from the database, which looked fine, and ran .revert(delete=True)
on it. However, it was not reverted; more precisely, nothing changed in the database.
Somehow I suspect this being a case of https://stackoverflow.com/questions/6546536/django-reversion-revert-manytomany-fields-outside-admin, but I cannot yet prove that.
