Description
I am trying to use migrations to create default groups, I tried to run the following procedure with migrations.RunPython()
def create_normal_users_group(apps, *args): auth = SimpleNamespace(**apps.all_models['auth']) myapp = SimpleNamespace(**apps.all_models['myapp']) ContentType = apps.get_model('contenttypes', 'ContentType') group = auth.group.objects.create(name='Normal Users') contenttypes = ContentType.objects.get_for_models(myapp.user, myapp.proxy) # there are more models... # ...
but it raises AttributeError
File "/home/user/projects/myapp/.venv/lib/python3.8/site-packages/django/contrib/contenttypes/models.py", line 89, in get_for_models opts_models = needed_opts.pop(ct.model_class()._meta, []) AttributeError: 'ContentType' object has no attribute 'model_class'
it works when I pass a single model to ContentType.objects.get_for_models()
, but get_for_models()
is supposed to work with multiple models.
