我创建使用Rails控制器生成控制器欢迎索引希望'heroku open'正在工作

This is my routes.rb 

Rails.application.routes.draw do 
    get 'welcome/index' 



    # For details on the DSL available within this file, see http://guides.rubyonrails.org/routing.html 
end

这是我welcome_controller.rb

class WelcomeController < ApplicationController 


    def index 
    end 
end

这是我的index.html.erb

<h1>Welcome#index</h1> 
<p>Find me in app/views/welcome/index.html.erb</p>

在production.rb我试图改变

'config.assets.compile = false' 
to 'config.assets.compile = true' with no success.

我试着但它不起作用。

$ heroku rake db:migrate 
$ heroku run rake db:setup

您是否在config.routes文件中设置了根路由？ – bkunzi01

是的。我在我的routes.rb文件中添加了'root'welcome＃index'。当我尝试在添加后启动rails服务器时，我收到错误：/Users/TheBabadook/Desktop/ribbit1/config/routes.rb:9:in''：undefined method'root'for main：Object（NoMethodError） – Sanctusdecadere

尝试增加你的路由的根路径文件：

root 'controller_name#action_name' #Make sure to use the actual controller and action names responsible for serving the homepage.

您应该添加根到您的config/routes.rb文件作为Guidelines

您可以使用这样的描述（在轨4/5）：

Rails.application.routes.draw do 
    root 'welcome#index' 
end

或者也有详细的方法（在轨道s 3）：root to: welcome#index

当我向我的routes.rb文件添加'root'welcome＃index'时收到此错误消息：/Users/TheBabadook/Desktop/ribbit1/config/routes.rb:9:in''：未定义的方法'根目录为主：对象（NoMethodError） \t从 – Sanctusdecadere

您是否已将根行包含在'Rails.application.routes.draw'块？ – XavM

heroku开放不起作用。下面的twitter克隆教程，ribbit
