works in 0.7.3. will also work in 0.7.4 Just not the current tip at the moment.
the regular mapper() setup is equivalent (see http://www.sqlalchemy.org/docs/orm/mapper_config.html#classical-mappings) : discriminator_expr = case(...) mapper(Person, ..., polymorphic_on=discriminator_expr, polymorphic_identity='person', properties={ 'discriminator':column_property(discriminator_expr) }) @event.listens_for(Person, ...) ... note the "event" part of this is just to set the "type" column automatically, it's not required.
