 332. Callable defaults
 4
 5You can pass callable objects as the ``default`` parameter to a field. When
 6the object is created without an explicit value passed in, Django will call
 7the method to determine the default value.
 8
 9This example uses ``datetime.datetime.now`` as the default for the ``pub_date``
10field.
