Cake PHP中同一个表的多个外键？

Question

Cake has its conventions for automating some functionality interaction between it's models and the tables they reference. Foreign keys should be called people_id, if they reference a table called people. How do I handle a case where a row holds two people, and needs foreign keys for both people? It's obvious that I can't duplicate the column names, having two people_id columns.

Consider a competition where you have two competitors. Each competitor is represented by a row in the competitor's table. The competitions table needs to refer to both of those competitors. How can I do this wouldn't breaking the automatic functionality that Cake offers?
