浜松Rails3道場其の壱 プロジェクト作成～Routing編Hamamatsurb#4 2011.06.08 @mackato
浜松Rails3道場の心得
習うより慣れろ
理論より実用
未知を恐れない
実際にRailsアプリを作ってみる
Wiki or CMS
全5回位で
今回は其の壱
スライド
プロジェクトの作成～Routing編
実演 Q&A
うまく出来るかな？(^_^;)
開発環境
Ruby Version 1.9.2
Rails Version 3.0.7
.rvmrcrvm ruby-1.9.2-p180@rails-3_0_7
rails new rails3dojo -m http://railswizard.org/ae25c16f22597ad5ea98.rb -J -T
新規アプリケーション作成RailsWizardが便利！
≠ CSS ≠ Erb
気にしない (^O^)／
gem uninstall rake -v=0.9.xbundle update
※ Rails3.1は0.9.1以降でOK!
Gemfilegem 'rake', '0.8.7'
cd ~/.powln -s /path/to/rails3dojoopen http://rails3dojo.dev/
Mac only!

RoutingとはHTTPリクエストとコントローラのアクションを
結びつける仕組み
HTTPリクエストMethods: GET, POST, PUT, DELETEPaths: /login, /pages/2, /items.xml
params[:id] format
参考: Rails Routing from the Outside In. http://guides.rubyonrails.org/routing.html
rails g controller welcome index
トップページ用のコントローラを生成
テストを追加spec/controllers/welcome_controller_spec.rb
# -*- coding: utf-8 -*-require 'spec_helper'
describe WelcomeController do
describe "#index" do it "should be successful" do get 'index' response.should be_success end it "GET / にマッチ" do { :get => "/" }.should route_to( :controller => "welcome", :action => "index" ) end end
end
テストを実行bundle exec rspec \
spec/controllers/welcome_controller_spec.rb
Rails3dojo::Application.routes.draw do # You can have the root of your site routed with "root" root :to => "welcome#index"end
config/routes.rb
root_path => /root_url => http://localhost:3000/
WelcomeController#index
rootのrouteを追加
もっかいテスト
＼(^o^)／
テストのパスを名前付きに修正spec/controllers/welcome_controller_spec.rb
# -*- coding: utf-8 -*-require 'spec_helper'
describe WelcomeController do
describe "#index" do it "should be successful" do get 'index' response.should be_success end it "GET root_path にマッチ" do { :get => root_path }.should route_to( :controller => "welcome", :action => "index" ) end end
end

レイアウトとスタイルを入れ替え
Rails3dojo::Application.routes.draw do # You can have the root of your site routed with "root" root :to => "welcome#index" resources :pagesend
config/routes.rb
PageのResource Routingを追加
追加
% rake routes
root /(.:format) {:controller=>"welcome", :action=>"index"}
pages GET /pages(.:format) {:action=>"index", :controller=>"pages"}
POST /pages(.:format) {:action=>"create", :controller=>"pages"}
new_page GET /pages/new(.:format) {:action=>"new", :controller=>"pages"}
edit_page GET /pages/:id/edit(.:format) {:action=>"edit", :controller=>"pages"}
page GET /pages/:id(.:format) {:action=>"show", :controller=>"pages"}
PUT /pages/:id(.:format) {:action=>"update", :controller=>"pages"}
DELETE /pages/:id(.:format) {:action=>"destroy", :controller=>"pages"}
rake:routes で確認
Resource Routing
Collection Member
index GET pages_pathnew GET new_page_path create POST pages_path
show GET page_path(id)edit GET edit_page_path(id)update PUT page_path(id)destroy DELETE page_path(id)
Pages Page
rails g controller pages index new
Pageリソース用のコントローラを生成
テストspec/controllers/pages_controller_spec.rb
# -*- coding: utf-8 -*-require 'spec_helper'
describe PagesController do
describe "#index'" do ... it "GET pages_path にマッチ" do { :get => pages_path }.should route_to(:controller => "pages", :action => "index" ) end end
describe "#new'" do ... it "GET new_page_path にマッチ" do { :get => new_page_path }.should route_to(:controller => "pages", :action => "new" ) end end
end
ショートカットメニューを追加app/views/layouts/application.html.haml
<!doctype html>... %h3 Shortcuts %ul %li= link_to "Home", root_path %li= link_to "Pages", pages_path %li= link_to "New Page", new_page_path
今回の開発はここまで
More Resource Routing
config/routes.rb
Namespace付きResource Routing
Rails3dojo::Application.routes.draw do # You can have the root of your site routed with "root" root :to => "welcome#index" resources :pages namespace "admin" do resources :pages endend
http://localhost:3000/admin/pages
リソース名の前にネームスペース名が追加される
Namespace付きResource Routing
% rake routes... admin_pages GET /admin/pages(.:format) {:action=>"index", :controller=>"admin/pages"} POST /admin/pages(.:format) {:action=>"create", :controller=>"admin/pages"} new_admin_page GET /admin/pages/new(.:format) {:action=>"new", :controller=>"admin/pages"}edit_admin_page GET /admin/pages/:id/edit(.:format) {:action=>"edit", :controller=>"admin/pages"} admin_page GET /admin/pages/:id(.:format) {:action=>"show", :controller=>"admin/pages"} PUT /admin/pages/:id(.:format) {:action=>"update", :controller=>"admin/pages"} DELETE /admin/pages/:id(.:format) {:action=>"destroy", :controller=>"admin/pages"}

Rails3dojo::Application.routes.draw do # You can have the root of your site routed with "root" root :to => "welcome#index" resources :pages do resources :comments endend
http://localhost:3000/pages/2/comments
子リソース名の前に親リソース名が追加される親リソースの指定は必須

Resource Routingにアクションを追加
Rails3dojo::Application.routes.draw do # You can have the root of your site routed with "root" root :to => "welcome#index" resources :pages do get 'freeze', :on => :collection get 'preview', :on => :member endend
http://localhost:3000/pages/freezehttp://localhost:3000/pages/2/preview

Resource Routingで大体OK
結論

Q&A
多分、ActiveRecord
