Python version: 3.2.3 sqlalchemy version: 0.7.9 (Please see the attached source file.) I have a class Simple, which has two subclasses - MixedFirst and MixedSecond. These two subclasses have a field in common, namely, mixed. So I have put it in a separate class (a mixin) named Mixin, which both MixedFirst and MixedSecond inherit from. I am using single table inheritance to map this to database.
I am adding one instance each of Simple, MixedFirst and MixedSecond twice. Once in add_rows(), and once in run_stuff(). When I query the table and polymorphically load all the instances, the "mixed" field on some objects contains a value of type sqlalchemy Column, which is incorrect. Here are some more specific observations: - The rows added in run_stuff() work as expected (even if you comment out the inserts in add_rows). - The rows added in add_rows() show up the error of ".mixed" ending up showing the wrong value (that of a SA column instead of the field value). - If we reorder the declaration of MixedFirst and MixedSecond, the error of ".mixed" switches over to the instance of the class that gets declared later. I also tried using declared_attr as suggested here - http://docs.sqlalchemy.org/ru/latest/orm/extensions/declarative.html, but that made no difference. This looks like a bug but I would first like to confirm it before filing a bug report. -- Cheers, Rahul. -- You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
