when I do stuff like this on the Web (single and multi-page edits), I build up a dict of 'changes'. When rendering forms, I default to the key in changes or fallback to the sqlalchemy object. when ready to save, I copy over the changes to the object - if there are any changes - and flush.
the nice thing about dealing with dicts, is that an empty dict means no changes, and a full dict means there are changes. it makes it way easier to catch "you've changed nothing!" issues. -- You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
