+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.
