Ruby on Rails 网站在本地运行，路由正确，但在 heroku 上得到 404 [英] Ruby on Rails website worked locally, routes correct, but on heroku get 404

问题描述

这是我遇到的一个非常奇怪的错误.我在导轨上使用红宝石.在本地(在云 9 上)一切正常，我成功地将它推送到 Heroku.我已经运行 db:migrate 没有错误.尽管如此，我收到错误消息您要查找的页面不存在"并且日志显示 404.我已检查文件并且它们已正确上传.我的路线:

This is a really strange error that I've encountered. I use ruby on rails. Everything works fine locally (on cloud 9) and I successfully pushed it to Heroku. I have run db:migrate with no error. Nonetheless, I get error "The page you were looking for doesn't exist" and the log says 404. I have checked the files and they have been correctly uploaded. My routes:

  root 'application#index'
  get '/index/:type' => 'application#index'
  get '/index/' => 'application#index'
  get '/benchmark/' => 'application#benchmark'
  get '/benchmark/:type' => 'application#benchmark'
  get '/benchmarkupdate/:name' => 'application#benchmark'
  get '/indexupdate/:name' => 'application#index'

我在正确的位置有文件.我认为路由没有任何问题，并且它在本地工作.

I have files in correct locations. I don't see any problem with routing and it has worked locally.

是否还有其他原因可能导致此问题?

Is there anything else that might cause this problem?

推荐答案

问题是你没有设置根路由，意思是当有人在没有任何路径的情况下访问 www.example.com 之后他们将转到根路由.在你的路由文件中添加类似

The problem is you haven't set a root route meaning when someone goes to www.example.com without any path after it they are going to the root route. In your routes file add something like

root 'application#index'

或者您希望人们第一次访问您的网站时访问的任何控制器和操作以及相应的视图.

or whatever controller and action and the corresponding view that you want people to go to when they first visit your site.
