RUBY VERSION

BUNDLED WITH

我创建了一个控制器，使用rails生成控制器欢迎索引，希望＆＃39; heroku open＆＃39;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

这是我的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中我尝试更改

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

我试过但它没有用。 

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

2 个答案:

答案 0 :(得分：1)

尝试在路径文件中添加根路径：

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

答案 1 :(得分：0)

您应该按照Guidelines

中的说明在config/routes.rb文件中添加根目录

您可以像这样使用它（在rails 4/5中）：

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

或者还有详细方法（在rails 3中）：root to: welcome#index
