Adding new custom permissions in Django

Question

I am using custom permissions in my Django models like this:

class T21Turma(models.Model):
    class Meta:
        permissions = ((\"can_view_boletim\", \"Can vi

You can connect to the post_migrate signal in order to update the permissions after migration. I use the following code, slightly modified from Dev with Passion and originally from django-extensions.

# Add to your project-level __init__.py

from south.signals import post_migrate

def update_permissions_after_migration(app,**kwargs):
    """
    Update app permission just after every migration.
    This is based on app django_extensions update_permissions management command.
    """
    from django.conf import settings
    from django.db.models import get_app, get_models
    from django.contrib.auth.management import create_permissions

    create_permissions(get_app(app), get_models(), 2 if settings.DEBUG else 0)

post_migrate.connect(update_permissions_after_migration)
