Currently, ActiveRecord models with multiple words cannot have their
inverse associations detected automatically.

d6b03a3767 Getting rid of the +automatic_inverse_of: false+ option in associations in favor
of using +inverse_of: false+ option. Changing the documentation and
adding a CHANGELOG entry for the automatic inverse detection feature.

26d19b4661 Created a method to automatically find inverse associations and cache
the results. Added tests to check to make sure that inverse associations are
automatically found when has_many, has_one, or belongs_to associations
are defined.

ccea98389a 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.
