Question

获得可怕的路由错误。 Ubuntu 16.04在Win10上运行。 Rails 2.4.1。使用Sublime。

routes.rb中：

Rails.application.routes.draw do

  get "welcome/home", to: "welcome#home"

end

我有一个welcome_controller.rb（在app / controllers中）：

class WelcomeController < ApplicationController

end

在SO上尝试了很多解决方案，但似乎无法实现这一点。注意：每次更改后我都会重新启动rails以查看更改。 我可以做的其他日志记录？不同的代码？

Answer 1

添加def home功能并在欢迎控制器中将其留空。像这样。如果你想要它做某事，你可以加入它。但是现在，请把它留空！

def home
end

Answer 2

尝试通过在

之前添加/来使您的路径相对于root

  get "/welcome/home",  to: "welcome#home"

并向您的控制器添加主页操作...

 Class WelcomeController < ApplicationController
   def home
   end
 end

Answer 3

共识是配置就在这里（rails），但可能是Win10 / Ubuntu设置的问题。我不会再进一步调查。如果我遇到了什么，我会更新线程。
