From ccea98389abbf150b886c9f964b1def47f00f237 Mon Sep 17 00:00:00 2001
From: Murray Steele <muz@h-lame.com>
Date: Fri, 1 May 2009 16:01:13 +0100
Subject: Providing support for :inverse_of as an option to associations.

You can now add an :inverse_of option to has_one, has_many and belongs_to associations.  This is best described with an example:

class Man < ActiveRecord::Base
  has_one :face, :inverse_of => :man
end

class Face < ActiveRecord::Base
  belongs_to :man, :inverse_of => :face
end

m = Man.first
f = m.face

Without :inverse_of m and f.man would be different instances of the same object (f.man being pulled from the database again).  With these new :inverse_of options m and f.man are the same in memory instance.

Currently :inverse_of supports has_one and has_many (but not the :through variants) associations.  It also supplies inverse support for belongs_to associations where the inverse is a has_one and it's not a polymorphic.
