If :meth:`.get_internal_type` returns a string that is not known to Django for
the database backend you are using -- that is, it doesn't appear in
``django.db.backends.<db_name>.creation.data_types`` -- the string will still be
used by the serializer, but the default :meth:`~Field.db_type` method will
return ``None``. See the documentation of :meth:`~Field.db_type` for reasons why
this might be useful. Putting a descriptive string in as the type of the field
for the serializer is a useful idea if you're ever going to be using the
serializer output in some other place, outside of Django.
