we're working on easily allowing column_property() as a discriminator if you want to make a CASE statement. right now its tedious as per the example at http://www.sqlalchemy.org/trac/ticket/2227 (note second example is single table, polymorphic_on needs to be on all subclasses at the moment) -- You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
