我如何使用以下格式的網址

Question

我可以在rails generate controller static_pages about的幫助下生成一個網址和關聯的網頁。因此，網址會是這樣的www.bla.com/static_pages/about'. Now I want to generate this url bla.com/help`而不使用產生的，

我在routes.rb中添加的路由這樣 get 'help'

然後我說在application_controller.rb行動這樣
def hello render text: "Hello" end

然後啓動服務器時，我收到以下錯誤

Answer 1

缺失：路由定義中的控制器鍵，請檢查您的 路由。 （引發ArgumentError）

由於錯誤狀態，你需要指定controller和action匹配的route。以下應該工作。

get "help", to: 'static_pages#about', as: 'help' 
        ^^^^^^ ^^^^ 
       controller action 

另外，我建議你遵循這些Guides關於如何定義路徑清晰的認識。
