Comment (by flyte):
I had this problem on Django 3.1.7 because the `contenttypes` migration
`0002_remove_content_type_name` was not being run before my migration.
Fixed it by adding it as a dependency:
{{{
from django.apps import apps
from django.contrib.auth.management import create_permissions
from django.db import migrations
def create_all_permissions(*args, **kwargs):
for app_config in apps.get_app_configs():
app_config.models_module = True
create_permissions(app_config, apps=apps, verbosity=0)
app_config.models_module = None
def create_moderation_group(apps, schema_editor):
Permission = apps.get_model("auth", "Permission")
perms = Permission.objects.filter(
codename__in=["moderate_submission", "view_submission"]
)
assert len(perms) == 2
Group = apps.get_model("auth", "Group")
group = Group.objects.create(name="Submission Moderators")
group.permissions.set(perms)
class Migration(migrations.Migration):
dependencies = [
("api", "0001_initial"),
("contenttypes", "0002_remove_content_type_name"),
]
operations = [
migrations.RunPython(create_all_permissions),
migrations.RunPython(create_moderation_group),
]
}}}
