``ForeignKey`` and ``OneToOneField`` ``on_delete`` argument
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
In order to increase awareness about cascading model deletion, the
``on_delete`` argument of ``ForeignKey`` and ``OneToOneField`` will be required
in Django 2.0.
Update models and existing migrations to explicitly set the argument. Since the
default is ``models.CASCADE``, add ``on_delete=models.CASCADE`` to all
``ForeignKey`` and ``OneToOneField``\s that don't use a different option. You
can also pass it as the second positional argument if you don't care about
compatibility with older versions of Django.

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