Django custom manager filter query set (by parameter)

问题

I would like my models to automatically filter by current user.

I did this by defining:

class UserFilterManager(models.Manager):
    def get_queryset(self):
        return super(UserFilterManager, self).get_queryset().filter( owner=get_current_user() )

where get_current_user() is a middleware which extracts the current user from the request passed to Django.

However, I need to use the models from Celery which does not go through the middleware. In these cases

MyModel.objects.all()

needs to become

MyModel.objects.filter(user=<some user>)

To avoid wrong queries caused by forgetting to filter by user, I would like the model/manager/queryset to assert when a query (any query) is performed without a filter on user.

Is there a way to achieve this? From what I see get_queryset() cannot receive parameters and models.QuerySet won't provide aid here.
