You are using and_() over a single parameter. Moreover, you're probably using SA < 0.4 and you need to use IndicatorGroups.c.indicatorgroup Note the '.c.' -- that goes away with the 0.4 API overhaul. So either upgrade SA, or use the .c attribute You don't usually need to keep a reference to the mappers, you can always get them from the mapped classes. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
