I would likely just map traditionally and have "User" be a non-mapped proxy object to a collection of "email/ip" objects. Else if you're looking to make life painful, map User to a view or select() that uses DISTINCT to get just "email" as a row, then a collection of "ip" objects linked on "foreign key". Or just create a "user" table with the same info as that view (i.e. materialize it). -- You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
