Custom manager classes available through ``prefetch_related`` must define a ``_apply_rel_filters()`` method
-----------------------------------------------------------------------------------------------------------
If you defined a custom manager class available through
:meth:`~django.db.models.query.QuerySet.prefetch_related` you must make sure
it defines a ``_apply_rel_filters()`` method.
This method must accept a :class:`~django.db.models.query.QuerySet` instance
as its single argument and return a filtered version of the queryset for the
model instance the manager is bound to.
