Michael, transaction.account_id is not a primary key of transactions table. I added fields I use for grouping to primary_key. Then I had to add foreign_key argument to 'summary' relation() call. And finally it all worked as expected.
However, I noticed that it doesn't actually matter which fields I use for primary_key or foreign_key. As long as I specify these parameters and use _any_ fields as values things start working and that doesn't smell good. Anyway, thanks a lot for you help. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
