創建Shop項目
$ rails new shop
利用scaffold創建資源
$ rails generate scaffold production name:text price:float amount:integer
顯示rails爲資源分配的routes地址
$ rake routes | grep production
DB Migrate
$ bin/rails db:migrate RAILS_ENV=development
Start Server
development環境下，修改code無需重啓server。
$ rails server
設置首頁爲productions/index
在Routes.rb中進行設置，有2種設置方法
get '/' => 'productions#index'
root 'productions#index'
給資源添加訪問地址
get '/addProduction' => 'productions#new'
match 規則 & 傳參
如果需要傳參
match '/addProduction/:name/:price' => 'productions#new'
那麼之後就可以在controller中獲取這兩個參數
@name = params[:name]
