Rails没有路线匹配{：controller =>“devise / products”} [英] Rails No route matches {:controller=>"devise/products"}
本文介绍了Rails没有路线匹配{：controller =>“devise / products”}的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
当我尝试登录或注册（我使用Devise GEM登录）时，我的rails应用程序出现以下错误。 code>路由错误
没有路由匹配{：controller =>devise / products}
应用程序的所有源代码可以在这里找到： https://github.com/rossmc/
我试过在 application.html.erb中更改 link_to / strong>& product / index.html.erb from：
<％= link_to'登录' new_user_session_path％>
to：
code><％= link_to'登录'，：controller => / products，new_user_session_path％> ;.
但这只会引起更多错误。
<有趣的是，登录功能和我添加了部分购物车之前，路线正常工作，我最后一次提交时放在 application.html.erb 中。当我删除这个部分时，路由错误消失，但是我松开了我的部分 views / cart / _cart.html.erb 。
下面是控制台当我尝试登录并从运行rake routes命令。
提前感谢您抽出时间来看看。

找到了吗？日志显示它已经渲染了一些部分，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？这是：
<％= link_to'保持购物'，：controller => ：产品％>
<％= link_to'Empty Cart'，：controller => cart，：action => clearCart％>
<％= link_to'继续检出'，：controller => cart，：action => createOrder％>
正如Ryan在以下评论，Rails正在寻找 Devise 因为这是你正在渲染的那个。
更简单的说，你可以提供它的路由名称（你将在 rake路线），您可以向帮助者添加 _path 以形成URL。 products_path 最终成为 products＃index 的URL字符串。
在您的情况下
<％= link_to保持购物，products_path％>
<％= link_to'清空购物车'，clearCart_path％>
<％= link_to'继续检出'，checkout_path％>
听你的堆栈跟踪，他们正在和你说话！
I get the below error on my rails application when I try to login or register (I'm using the Devise GEM for logins).
Routing Error
No route matches {:controller=>"devise/products"}
All the source code for the application can be found here: https://github.com/rossmc/topsnowboards
I've tried changing the link_to in application.html.erb & product/index.html.erb from:
<%= link_to 'sign in', new_user_session_path %>
to:
<%= link_to 'sign in', :controller => "/products", new_user_session_path %>.
But this just throw up more errors.
Interestingly the login features & routes were working fine before I added a partial for the shopping cart, which I placed in the application.html.erb on my last commit. When I remove this partial the routing error disappears but I loose my partial views/cart/_cart.html.erb.
Below is the console dump from when I try to login & run the rake routes command. Thanks in advance for taking the time to look at this.

Found it? The log shows it has rendered a bunch of partials, down to cart/_cart.html.erb. It even tells you the error happens on line 49. Now what's on line 49? This:
<%= link_to 'Keep Shopping', :controller => :products %>
<%= link_to 'Empty Cart', :controller => "cart", :action => "clearCart" %>
<%= link_to 'Proceed to Check Out', :controller => "cart", :action => "createOrder" %>
As Ryan rightly points out in the following comment, Rails is looking for a partial scoped under Devise since this is the one under which you're rendering.
More simply, you can just feed it the route name (the one you'll find in rake routes) to which you add _path for a helper to form a URL. products_path ends up being the URL string for products#index.
Which gives in your case
<%= link_to 'Keep Shopping', products_path %>
<%= link_to 'Empty Cart', clearCart_path %>
<%= link_to 'Proceed to Check Out', checkout_path %>
Listen to your stack traces, they're talking to you!
