I have a setup like this: class Entity(object): pass class Persoon(Entity): pass
entity_tabel = Table('contact', metadata, Column('contactid', Integer, primary_key=True), Column('voornaam', String(75)), Column('naam', String(75)), Column('organisatietypeid', Integer)) entity_mapper = mapper(self.Entity, entity_tabel, polymorphic_on=entity_tabel.c.organisatietypeid, polymorphic_identity=None) persoon_mapper = mapper(self.Persoon, inherits=entity_mapper, polymorphic_identity=None, properties={ 'achternaam':entity_tabel.c.naam}) Now, I want to add a 'Persoon': p = Persoon() p.voornaam = 'firstname' p.achternaam = 'surname' mySession.add(p) mySession.commit() But this leaves my 'naam' field to 'NULL'. Only if I do: p = Persoon() p.voornaam = 'firstname' p.naam = 'surname' mySession.add(p) mySession.commit() Things work as they should. How is this possible? I thought that by saying: properties={'achternaam':entity_tabel.c.naam} you actually rename the column, but it seems it creates another attribute which would lead to unexpected results in my case. Anybody more info about this? --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
