Fixed #22601 -- Added a note about model inheritance.

=================

Model inheritance in Django works almost identically to the way normal

class inheritance works in Python. The only decision you have to make

is whether you want the parent models to be models in their own right

(with their own database tables), or if the parents are just holders

of common information that will only be visible through the child

models.

class inheritance works in Python, but the basics at the beginning of the page

should still be followed. That means the base class should subclass

:class:`django.db.models.Model`.

The only decision you have to make is whether you want the parent models to be

models in their own right (with their own database tables), or if the parents

are just holders of common information that will only be visible through the

child models.

There are three styles of inheritance that are possible in Django.
