What means this error ? InvalidRequestError: Parent instance <class 'common.model.CbteDet'> is not bound to a Session, and no contextual session is established; lazy load operation of attribute 'planilla' cannot proceed
Note: CbteDet object mapper have a "planilla" relation attribute. (one to one relationship) I do a session.clear(), all time, after of session.save_or_update([obj]) Can this be the problem? When is advisable do a session.clear() ? --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
