Rails core - Jun 2008 - Patch to add :primary_key option to has_many and has_one associations

Hey all. I''m pimping for a patch that my colleague, Andre Arko,  
submitted originally:

http://rails.lighthouseapp.com/projects/8994/tickets/292-add-has_many-primary_key-option

I extended it to work with has_one associations, too. We have a couple  
instances in our app where we need an association that isn''t keyed off
the default primary key of the model. This patch allows you to use  
a :primary_key option to specify which key in the model should be used  
for the association.

Cheers,

This sounds like a good feature, but isn''t "primary_key" a
confusing
choice of names for that option? What about  "alternate_key"?

Yeah, I was thinking that myself. What about just :key?
