レイルに乗ってみた〜Rails of Ruby on Rails その14「注文処理で一寸ばかり躓いた(つдT)」

レイルに乗ってみた〜目次
書籍『Rails of Ruby on Rails ~Case of LOCUSANDWONDERS.COM~』で勉強してみた（P157〜）

Orderモデル作成

G5:~/work/locus username$ script/generate model order
      exists  app/models/
      exists  test/unit/
      exists  test/fixtures/
      create  app/models/order.rb
      create  test/unit/order_test.rb
      create  test/fixtures/orders.yml
      exists  db/migrate
      create  db/migrate/20080919060805_create_orders.rb

OrderItemモデル作成

G5:~/work/locus username$ script/generate model order_item
      exists  app/models/
      exists  test/unit/
      exists  test/fixtures/
      create  app/models/order_item.rb
      create  test/unit/order_item_test.rb
      create  test/fixtures/order_items.yml
      exists  db/migrate
      create  db/migrate/20080919061426_create_order_items.rb

マイグレーションファイル修正

/work/locus/db/migrate/20080919060805_create_orders.rb
書籍通りなので略。
P158の「012_create_orders.rb」は「012_create_order_items.rb」のことかな？
/work/locus/db/migrate/20080919061426_create_order_items.rb
内容は書籍通りなので略。

マイグレーション実行

G5:~/work/locus username$ rake db:migrate

Orderモデルの修正

次のファルを書き換え。
/work/locus/app/models/order.rb
/work/locus/app/models/order_item.rb
書籍通りなので略。
書き込み量が多くなってきたなぁ(||ﾟДﾟ)

決済・注文画面の作成 Orderコントローラを作成

G5:~/work/locus username$ script/generate controller order new confirm create

      exists  app/controllers/
      exists  app/helpers/
      create  app/views/order
      exists  test/functional/
      create  app/controllers/order_controller.rb
      create  test/functional/order_controller_test.rb
      create  app/helpers/order_helper.rb
      create  app/views/order/new.html.erb
      create  app/views/order/confirm.html.erb
      create  app/views/order/create.html.erb
Loaded suite script/generate
Started

次のファイルを書き換え。
/work/locus/app/controllers/order_controller.rb
書籍通りなので略。
ちなみにサンプル使う場合は、def createの下記のところをとりあえずコメントアウト。

  def create
    @order = Order.new(params[:order])
    cart_to_order
  
    if params[:btn_cancel]
      render :action => 'new'
    elsif @order.save
      @cart.cart_items.destroy_all
#       logger.info "EMAIL:" + @order.email
#       OrderMailer.deliver_order(@order)
    else
      render :action => 'new'
    end
  end
