Ruby on Rails

class Address < ActiveRecord::Base
belongs_to :addressable, polymorphic: true
end

My Second Model: app/models/user.rb

class User < ActiveRecord::Base
has_many :addresses, as: :addressable
end

My third model: app/models/company.rb

class Company < ActiveRecord::Base
has_many :addresses, as: :addressable
end

For Address table, I have this migration:

class CreateAddresses < ActiveRecord::Migration
def change
create_table :addresses do |t|
t.string :description
t.references :addressable, polymorphic: true
t.timestamps
end
end
end
