There is currently no work underway to support composite keys with active record. At least in rails itself. There might well be some plugins under development. > I'm not trying to use legacy databases.

For example, ID for the third comment of forum > topic #87 should be (87, 3) not (87, 1074), format being (topic_id, > reply_id). You shouldn't be thinking about the IDs, they're only there for the sake of persistance, consider them the logical equivalent of an address in memory. It doesn't matter what the number is, just that there *is* a number. -- Cheers Koz _______________________________________________ Rails-core mailing list Rails-core@lists.rubyonrails.org http://lists.rubyonrails.org/mailman/listinfo/rails-core
