Django-polymorphic simplifies using inherited models in django projects. when a query is made at the base model, the inherited model classes are returned.

features:
* full admin integration.
* orm integration:
+ support for foreignkey, manytomanyfield, onetoonefield descriptors.
+ support for proxy models.
+ filtering/ordering of inherited models (artproject___artist).
+ filtering model types: instance_of(...) and not_instance_of(...)
+ combining querysets of different models (qs3 = qs1 | qs2)
+ support for custom user-defined managers.
* uses the minimum amount of queries needed to fetch the inherited models.
* disabling polymorphic behavior when needed.
