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.

Ensure JoinAssociation uses aliased table name when multiple associations have hash conditions on the same table

Added :touch option to belongs_to associations that will touch the parent record when the current record is saved or destroyed [DHH]

Ensure NoMethodError isn't raised when some of the nested eager loaded associations are empty [#1696 state:resolved]

If foreign key constraints are in place then deleteing the associated object first will cause a foreign key violation

There are several situations it doesn't cater for, and the inconsistency isn't worth blocking 2.2.

explicitly including child associations that are also included in the parent association definition should not result in double records in the collection/double loads (#1110)
