Replying to myself, this is the temporary solution to the issue, I
described yesterday:
class Element(...)
...
def get_categories(self):
return Category.objects.distinct().extra(
tables=['elementapp_element_categories AS eec'],
where=['categoryapp_category.id=eec.category_id',
'eec.element_id=%d' % (self.id or 0)],
)
Now I can use
e.get_categories()
instead of
e.categories.all()
and get the related objects without errors.
