QuerySet inharitance in django-polymorphic

[fed239]

I'd like to add filter_by_user methods to all QuerySet classes defined for child polymorphic models and use them to filter objects of every model when called for the base model. filter_by_user methods may be different for different child models. Is this possible?

I tried like in the following code but it didn't work.

class MyBaseQuerySet(PolymorphicQuerySet):
    def filter_by_user(self, user):
        return self.all()


class MyBaseModel(PolymorphicModel):
    ...
    objects = PolymorphicManager(MyBaseQuerySet)


class MyChild1QuerySet(MyBaseQuerySet):
    def filter_by_user(self, user):
        return self.filter(fieldA__lt=user.profile.propA)


class MyChild1Model(MyBaseModel):
    fieldA = models.IntegerField()
    ...
    objects = PolymorphicManager(MyChild1QuerySet)


class MyChild2QuerySet(MyBaseQuerySet):
    def filter_by_user(self, user):
        return self.filter(fieldB__gt=user.profile.propB)


class MyChild2Model(MyBaseModel):
    fieldB = models.IntegerField()
    ...
    objects = PolymorphicManager(MyChild2QuerySet)

When I call MyBaseModel.objects.filter_by_user(john) magic doesn't happen and only base queryset filter_by_user is called.

I think I'm seeing the same thing for this scenario:

class MyBaseModel(PolymorphicModel):
    ...
    # no "objects =" defined.

class SubclassFeedManager(PolymorphicManager):
    def get_queryset(self):
        ...

class MySubModel(MyBaseModel):
    objects = SubclassFeedManager()


...

MySubModel.objects.all()

This call doesn't use the SubclassFeedManager() at all.

Can somebody please suggest a workaround for this issue? I also want the custom manager to be called on each of the child classes when you call the base class custom manager.
