I haven't used this, so I don't know if this helps, but you may be interested in a couple of the functions described at http://www.sqlalchemy.org/docs/reference/orm/mapping.html#attribute-util ities In particular, either the instance_state() function or the get_history() function might be useful. I'm not sure there's much documentation for either the History class or the InstanceState class so you'll have to read the code in sqlalchemy.orm.state and sqlalchemy.orm.attributes Hope that helps, Simon -- You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
