Compare with previous version

I was able to check it from the django shell, calling save after a state change fails with save()). You have to specify which fields are to be updated (which is OK). As there is no way to set a read-only model field, we'll live with it

The exception is pretty straightforward

>>> wa.save()
Traceback (most recent call last):
  File "/home/bastien/Envs/ark/lib/python3.10/site-packages/django/db/backends/utils.py", line 89, in _execute

The above exception was the direct cause of the following exception:
