Скачать или смотреть Django Model Inheritance - InheritanceManager from django-model-utils

The django-model-utils package provides us an InheritanceManager that we can apply to the base class when we have a model inheritance tree.

This allows us to retrieve the correct subclasses when querying, rather than simply getting instances of the parent class,

We will add django-model-utils and use this InheritanceManager in this video.

We'll see the two methods it adds to our Django Querysets:

1. select_subclasses()
2. get_subclass()
