Description

Hi,
I am trying to create a django group with permissions to create competitions so that users would need to be added to this group by administrators before they can create competitions. I want regular authenticated users to not have the permission to create competitions. I have tried implementing this by creating a new permission class IsCompetitionCreator similar to the existing IsOrganizationEditor permission in src/apps/api/permissions.py. Then I changed this file src/apps/api/views/competitions.py to use: if self.action in ['create']: self.permission_classes = [IsCompetitionCreator], instead of using [IsAuthenticated]. I made sure to restart django and run the migration, however, when I test by creating a new user, I see that they still have permissions to create competitions. I also see on the django site administration, that every user shows the Competition Creator group, but I checked that the group was actually empty. Is there a better way I can go about creating this group, or do you guys have any idea why this method is not working?

Thanks

Research direction

Start with src/apps/api/permissions.py and src/apps/api/views/competitions.py, then reproduce the behavior using an empty Competition Creator group and a newly created user. Check why the create action still permits regular authenticated users and why the group appears assigned in Django administration; done means only users in the intended group can create competitions.
