Instead, you need to map a class to your secondary table directly, such that it has 1-many relations with the Document and Author classes. You can then use the 'associationproxy' extension to hide the details. See the docs at http://www.sqlalchemy.org/docs/05/mappers.html#association-pattern and http://www.sqlalchemy.org/docs/05/reference/ext/associationproxy.html#as sociationproxy Hope that helps, Simon --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
