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.
