バナー配信システムを作る（１）

詳しくはあとでまとめる。続くかどうかはわからない

ユースケース

• ユーザ登録ができる
• キャンペーンが登録できる
• キャンペーンにバナーが登録できる
• バナー貼り付け用のコードが取得できる
• バナーのインプレッション数、クリック数が取得できる

とりあえずはじめる

それがRails流

キャンペーンのCRUDを作る

本当はユーザ管理を先につくりたいけど、先に動くようにするのがアジャイル（多分違う）

D:\public_html>cd opt

D:\public_html\opt>rails generate campaign name:string
Could not find generator campaign.

D:\public_html\opt>rails g scaffold campaign name:string
      invoke  active_record
      create    db/migrate/20100915002636_create_campaigns.rb
      create    app/models/campaign.rb
      invoke    test_unit
      create      test/unit/campaign_test.rb
      create      test/fixtures/campaigns.yml
       route  resources :campaigns
      invoke  scaffold_controller
      create    app/controllers/campaigns_controller.rb
      invoke    erb
      create      app/views/campaigns
      create      app/views/campaigns/index.html.erb
      create      app/views/campaigns/edit.html.erb
      create      app/views/campaigns/show.html.erb
      create      app/views/campaigns/new.html.erb
      create      app/views/campaigns/_form.html.erb
      invoke    test_unit
      create      test/functional/campaigns_controller_test.rb
      invoke    helper
      create      app/helpers/campaigns_helper.rb
      invoke      test_unit
      create        test/unit/helpers/campaigns_helper_test.rb
      invoke  stylesheets
      create    public/stylesheets/scaffold.css

テーブルを作成

D:\public_html\opt>rake db:migrate
(in D:/public_html/opt)
==  CreateCampaigns: migrating ================================================
-- create_table(:campaigns)
   -> 0.0000s
==  CreateCampaigns: migrated (0.0000s) =======================================

動作を確認

D:\public_html\opt>rails server
=> Booting WEBrick
=> Rails 3.0.0 application starting in development on http://0.0.0.0:3000
=> Call with -d to detach
=> Ctrl-C to shutdown server

http://localhost:3000/campaigns/

やった。

登録とかもきちんとできる。
