Rails 没有路由匹配 {:controller=>“devise/products"} [英] Rails No route matches {:controller=>"devise/products"}
本文介绍了Rails 没有路由匹配 {: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时，我的 rails 应用程序出现以下错误(我使用 Devise GEM 进行登录).
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"}
可以在此处找到该应用程序的所有源代码:https://github.com/rossmc/topsnowboards
All the source code for the application can be found here: https://github.com/rossmc/topsnowboards
我尝试更改 application.html.erb 中的 link_to &product/index.html.erb 来自:
I've tried changing the link_to in application.html.erb & product/index.html.erb from:
<%= link_to 'sign in', new_user_session_path %>
到:
<%= link_to 'sign in', :controller => "/products", new_user_session_path %>.
但这只会引发更多错误.
But this just throw up more errors.
有趣的是登录功能和在我为购物车添加部分之前，路由工作正常，我在上次提交时将其放置在 application.html.erb 中.当我删除这个部分路由错误消失但我失去了我的部分views/cart/_cart.html.erb.
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.
以下是我尝试登录时的控制台转储 &运行 rake 路由命令.提前感谢您抽出时间查看此内容.
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.

更仔细地查看堆栈跟踪:
Look more closely at your stack trace:

找到了吗?日志显示它已经渲染了一堆部分，直到 cart/_cart.html.erb.它甚至会告诉您错误发生在第 49 行.现在第 49 行是什么?这:
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" %>
正如 Ryan 在以下评论中正确指出的那样，Rails 正在寻找 Devise 下的部分范围，因为这是您正在渲染的范围.
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.
更简单的说，你可以给它提供路由名称(你会在 rake routes 中找到的那个)，你添加 _path 以便帮助程序形成一个网址.products_path 最终成为 products#index 的 URL 字符串.
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.
你的情况是什么
<%= link_to 'Keep Shopping', products_path %>
<%= link_to 'Empty Cart', clearCart_path %>
<%= link_to 'Proceed to Check Out', checkout_path %>
聆听您的堆栈跟踪，它们在与您交谈！
Listen to your stack traces, they're talking to you!
