Deploying Rails patches (diff)

I am having a problem with a belongs_to and a has_one :through relation which I found is a known bug in Ruby on Rails: http://rails.lighthouseapp.com/projects/8994/tickets/323-has_many-through-belongs_to_association-bug

This ticket has 6 different attachments. Do I need all of them, or just the latest one? I can't seem to find anywhere how one is supposed to deploy these patches. Preferably I would patch something in my project that overrides the installed rails stack as opposed to patching the installed rails stack. How do I do this?

Well exactly which patch you need to apply would depend on the ticket itself. The author could have split his work into several pieces or they might be successive versions of the same thing. Read the ticket to find out.

You can apply the patch to a copy of rails using git-apply (you'd want a copy of rails frozen into your app)
