with sqlalchemy 0.4.1, Is there an idiom for delete the children of the object without actually deleting the object itself?
I tried session.delete (obj) session.flush() # add new children session.save (obj) session.flush() But it gave me the error InvalidRequestError: Instance '[EMAIL PROTECTED]' is already persistent which does not appear correct either. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
