| 32. Callable defaults |
| |
| You can pass callable objects as the ``default`` parameter to a field. When |
| the object is created without an explicit value passed in, Django will call |
| the method to determine the default value. |
| |
| This example uses ``datetime.datetime.now`` as the default for the ``pub_date`` |
| field. |
