a "table level" validator would be a database-side CHECK CONSTRAINT or trigger. If you have mapper definitions separate from classes, theres nothing stopping you from adding attributes to the class over there, i.e. mapper(MyClass, mytable) MyClass.foo = some_validation_decorator(MyClass.foo) Personally I wouldn't bother (then again I use declarative for everything now). > > :) > > > --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
