Index('ix_some_other_class_01', SomeOtherClass.updated_on) Index('ix_some_other_class_02', SomeOtherClass.updated_on.asc()) Index('ix_some_other_class_03', SomeOtherClass.updated_on.desc()) I just want to avoid repetition, if possible :)you could use a __table_args__() callable with @declared_attr. Or use a mapping event like __declare_first__() or __declare_last__() (these are hooked into the before_configured / after_configured events which you could also use directly, e.g. http://docs.sqlalchemy.org/en/rel_1_0/orm/events.html?highlight=before_configure#sqlalchemy.orm.events.MapperEvents.before_configured)best regards, richard. --You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
