ruby-on-rails – Rails没有路由匹配{:controller =>“devise / products”}

当我尝试登录或注册时,我在rails应用程序上收到以下错误(我正在使用Devise GEM进行登录).

Routing Error
No route matches {:controller=>"devise/products"}

可以在此处找到应用程序的所有源代码:https://github.com/rossmc/topsnowboards

我试过更改application.html.erb&中的link_to. product / index.html.erb来自:

<%= link_to 'sign in', new_user_session_path  %>

至:

<%= link_to 'sign in', :controller => "/products", new_user_session_path %>. 

但这只会引发更多错误.

有趣的是登录功能&在我添加购物车的部分之前,路线工作正常,我在上次提交时将其放在application.html.erb中.当我删除此部分时,路由错误消失,但我丢失了部分视图/ cart / _cart.html.erb.

下面是我尝试登录时的控制台转储.运行rake routes命令.
提前感谢您抽出时间来看看这个.

仔细查看堆栈跟踪:

找到了?日志显示它已经呈现了一堆部分,一直到cart / _cart.html.erb.它甚至告诉你错误发生在第49行.现在第49行是什么?这个:

<%= link_to 'Keep Shopping', :controller => :products %>
<%= link_to 'Empty Cart', :controller => "cart", :action => "clearCart" %>
<%= link_to 'Proceed to Check Out', :controller => "cart", :action => "createOrder" %>

正如Ryan在the following comment中正确指出的那样,Rails正在寻找Devise下的部分范围,因为这是你正在渲染的那个.

更简单地说,您可以只为其添加路径名称(您在rake路径中找到的路径名称),并为其添加_path以形成URL. products_path最终成为products#index的URL字符串.

在你的情况下给出了

<%= link_to 'Keep Shopping', products_path %>
<%= link_to 'Empty Cart', clearCart_path %>
<%= link_to 'Proceed to Check Out', checkout_path %>

听听你的堆栈痕迹,他们正在跟你说话!
