✅

The pattern for a method that operates on a QuerySet is to use a model manager.

class CliProfileManager(models.Manager):
   def get_subscribed_clients(self, shop):
       return self.get_queryset().exclude(unsubscriptions__shop=shop)

class CliProfile(...):
     objects = CliProfileManager()


profiles = CliProfile.objects.filter(...)
subscribed = profiles.get_subscribed_clients()

subscribed = profiles.objects.get_subscribed_clients()
