Combining django Managers

Question

I have two django managers

Vote manager

class VoteManager(model.Manager):

    def all_with_vote_info(self):
        qs = super(VoteManager, self).get_query_set()
        qs = qs.annotate(score=Sum('votes__score', distinct=True))
        return qs

    ....

Soft Delete manager

class SoftDeleteManager(models.Manager):

    def all_active(self):
        qs = super(SoftDeleteManager, self).get_query_set()
        qs = qs.filter(time_deleted=None)
        return qs

    ....

How can I chain queryset results from VoteManager.all_with_vote_info, SoftDeleteManager.all_active, and any arbitrary number of manager methods?

Found a solution: PassThroughManager

https://django-model-utils.readthedocs.org/en/latest/managers.html#passthroughmanager

Update:

PassThroughManager has been deprecated, use Django’s built-in QuerySet.as_manager() and/or Manager.from_queryset() utilities instead.
