     2 6. Specifying ordering

     3 

     4 Specify default ordering for a model using the ``ordering`` attribute, which

     5 should be a list or tuple of field names. This tells Django how to order

     6 ``QuerySet`` results.

     7 

     8 If a field name in ``ordering`` starts with a hyphen, that field will be

     9 ordered in descending order. Otherwise, it'll be ordered in ascending order.

    10 The special-case field name ``"?"`` specifies random order.

    11 

    12 The ordering attribute is not required. If you leave it off, ordering will be

    13 undefined -- not random, just undefined.
