You need to place the order_by on the OneToMany side, and in your precise example, that means, on the backref. mitarbeiter = relation( mitarbeiterCL, uselist=False, backref=backref('abwesenheiten', order_by=abwesenheit_table.c.datumvon) ) -- Gaëtan de Menten http://openhex.org --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
