class Meta:

ordering = ['menu','parent','weight']
QuerySets like filter() and all() on Django-Nonrel keep returning empty, even though objects exists in the database. get() works fine.
I've also tried removing the meta attributes, but to no avail.

Answer 1

The problem is that class Meta: ordering = ['menu','parent','weight'].
This results in "INNER JOIN" statement that django-norel does not support it or implement it yet.
