+8. get_latest_by
+
+Models can have a ``get_latest_by`` attribute, which should be set to the name
+of a ``DateField`` or ``DateTimeField``. If ``get_latest_by`` exists, the
+model's manager will get a ``latest()`` method, which will return the latest
+object in the database according to that field. "Latest" means "having the date
+farthest into the future."
