It looks like I just confused myself, in my test case I got "None" returned and I thought it was a model definition issue but it was me leaving one of the columns used for the computed column at None.
So if I do just the following the read only column (FB SQL computed column) are working for me. class Quality(Base): __table__ = sa.Table(u'quality', metadata, ... sa.Column(u'comboname', sa.String(length=63, convert_unicode=False), server_default=""), ... ) # read only columns comboname = sao.column_property(__table__.c.comboname) Werner --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
