| 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 |
| ``QuerySet`` results. |
| |
| 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. |
