~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

|

To customize how the values are serialized by a serializer, you can override

:meth:`~Field.value_to_string`. Using ``value_from_object()`` is the best way

to get the field's value prior to serialization. For example, since our

.. method:: value_to_string(obj)
|

Converts ``obj`` to a string. Used to serialize the value of the field.
