Hi Matt get_db_prep_value() is called prior to saving in the database, this is where you should encrypt the data. to_python() is called on values loaded from the database, or deserialised, this is where you should decrypt the data. https://docs.djangoproject.com/en/dev/howto/custom-model-fields/#converting-database-values-to-python-objects Cheers Tom -- You received this message because you are subscribed to the Google Groups "Django users" group.
