capture or provide way to capture change_permission events

[shivam-coditation]

So, there is a need to notify end user about the permission changed and for that there should be a way to capture permissions that are changed(provide or revoked)

One approach is using Django signals.

@shivam-coditation One approach is using Django signals.

I tried it, but django_guardian do not provide explicit signals so I tried with Middleware so getting final list of object_level_permissions a user have and what I required is which permission is changed(provided or revoked)

One simple example using signals:

def capture_user_permission_changes(sender, instance, **kwargs):
    print(instance)
    pass


class YourAppConfig(AppConfig):
    default_auto_field = 'django.db.models.BigAutoField'
    name = 'yourapp'

    def ready(self):
        from django.db.models import signals
        from guardian.models import UserObjectPermission

        signals.post_save.connect(capture_user_permission_changes, sender=UserObjectPermission)

If you wanna capture permission changes at the API level I guess you can do it in serializers with a little bit more work.
Also, I guess two other options are available:

• Using Proxy models in Django.
• Customizing object permissions models in Guardian.
