Rails one-to-one relationship

Question

I have the following:

class User < ActiveRecord::Base
  has_one :car, :class_name => \'Car\', :foreign_key => \'user_id\'

class Car < ActiveRecord::         


        

Answer 1

Change the definition of the relationship slightly:

class User < ActiveRecord::Base
  has_one :car

class Car < ActiveRecord::Base
  belongs_to :worker, :class_name => 'User', :foreign_key => 'user_id'

And you'll establish what you're looking for. See: http://guides.rubyonrails.org/association_basics.html#the-has-one-association
