You could either create a custom type for the column to do translation to/from object form or use a property as a proxy to the varchar attribute. They're both pretty easy to implement: http://www.sqlalchemy.org/docs/04/types.html#types_custom http://www.sqlalchemy.org/docs/04/mappers.html#advdatamapping_mapper_overriding -j --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
