So, in my example above, the descriptor created with EventHostAssociation would be replaced with: descriptor = dejavu.ToOne('HostID', Contact, 'ID') descriptor.nearClass = Event Event._associations['Event Host'] = Event.Host = descriptor Does that look right?

And thanks for the contribution. :) Incidentally, in your (stripped-down) example, you don't need the EventHostAssociation subclass at all--just use ToOne. You only need a custom subclass if you're using some kind of derivative value to do the mapping (as opposed to the normal nearKey -> farKey comparison). Great writeup!
