-11. Relating an object to itself, many-to-one
-
-To define a many-to-one relationship between a model and itself, use
-``ForeignKey('self')``.
-
-In this example, a ``Category`` is related to itself. That is, each
-``Category`` has a parent ``Category``.
-
-Set ``related_name`` to designate what the reverse relationship is called.
