21   </div>
22   <h4 class="span8">Address</h4>
23   <div class="address">

   devise :database_authenticatable, :registerable,
         :recoverable, :rememberable, :trackable, :validatable, 
         :confirmable, :lockable

  has_one :address
end

アドレス.rb:

class Address < ActiveRecord::Base
  attr_accessible :name, :addrl1, :addrl2, :city, :state, :region_code

  belongs_to :user
end
