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.
