Programmatically creating a group : Can't access permissions from migration

Question

After seeing this post, I tried to create my own group at project setup with this migration :

from django.db import migrations
from django.contrib.auth.model         


        

Answer 1

One solution is call the update_permissions command before try to append a permission

from django.core.management import call_command

def update_permissions(schema, group):
    call_command('update_permissions')


operations = [
        migrations.RunPython(update_permissions, reverse_code=migrations.RunPython.noop),
        migrations.RunPython(create_group),
    ]

And as was commented don't import Group and Permission models use:

Group = apps.get_model("auth","Group")
Permission = apps.get_model("auth","Permission")
