Ruby on Rails

Well, i think that in the given example, u could put has_one :dog in the Owner Controller and ALSO a belongs_to :owner in the Dog's controller. That way, you'll have the relations of both controllers explicit in each of them improving readability.

use has_one and belongs_to and i guess: store each others for maintain integrity is the best way, always

for code readability's sake, you need to figure out where to put the foreign but not on both. for example, you have a 1-1

relationship between a dog and an owner.  it's better if you add the foreign key to the dogs table.

Class Dog < ActiveRecord::Base

  belongs_to :owner # owner_id is in the dogs table

end

Class Owner < ActiveRecord::Base

  has_one :dog

end

one more thing to consider is through associations.  you can't add a :through option to belongs_to.
