Instead of keeping two lines in the association table, I only keep one and make a rule that relateditem1 <= relateditem2. Here is the thread on graphs where Mike posted a working solution: http://groups.google.com/group/sqlalchemy/browse_frm/thread/4d81b50fbfd84195/8ea809a9532ad6ca The pastebin link in the thread doesn't work any more, but the code can be found here: http://www.sqlalchemy.org/trac/browser/sqlalchemy/trunk/examples/graphs/graph1.py Arnar --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
