Updating custom permissions not working properly

[DJ-Tom]

Hi,

I'm using Django 1.5 with South to sync my database.

According to a hint on Stackoverflow I added the following code to my procjects __init__.py to add permissions on every migration:

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.
    """
    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)

Adding custom permissions via "class Meta:" seemed to work quite well with the above code.

But now I added permissions to a few models and some of them were not added to the permission table - without any error message, nothing.

This permission was added:

    class Meta:
        permissions = (
            ("view_equipmentcat", "Can see equipment categories"),
        )


But not those (for example):

    class Meta:
        permissions = (
            ("view_equipment", "Can see equipment"),
        )

    class Meta:
        permissions = (
            ("view_rooms", "Can see rooms"),
        )


Is there a way to clear all custom permissions from auth_permission and force all custom permissions to be added again?
