-6. Specifying ordering
-
-Specify default ordering for a model using the ``ordering`` attribute, which
-should be a list or tuple of field names. This tells Django how to order the
-results of ``get_list()`` and other similar functions.
-
-If a field name in ``ordering`` starts with a hyphen, that field will be
-ordered in descending order. Otherwise, it'll be ordered in ascending order.
-The special-case field name ``"?"`` specifies random order.
-
-The ordering attribute is not required. If you leave it off, ordering will be
-undefined -- not random, just undefined.
