Description
See https://docs.djangoproject.com/en/1.4/howto/custom-model-fields/#django.db.models.Field.value_to_string , it gives a sample as
class HandField(models.Field): # ... def value_to_string(self, obj): value = self._get_val_from_obj(obj) return self.get_db_prep_value(value)
but it will not work in 1.4 due to TypeError: get_db_prep_value() takes at least 3 arguments (2 given)

I would use
get_prep_value
instead ofget_db_prep_value
. Opinions?
