Method serializable_value

django/db/models/base.py:816–831

Return the value of the field name for this instance. If the field is a foreign key, return the id value instead of the object. If there's no Field object with this name on the model, return the model attribute's value. Used to serialize a field's value (in

(self, field_name)

        )
