Rails没有路由匹配{：controller =>“devise / products”}
[英]Rails No route matches {:controller=>“devise/products”}
问题描述
I get the below error on my rails application when I try to login or register (I'm using the Devise GEM for logins). 
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"}
All the source code for the application can be found here: https://github.com/rossmc/topsnowboards 可以在此处找到应用程序的所有源代码： https ： //github.com/rossmc/topsnowboards
I've tried changing the link_to in application.html.erb & product/index.html.erb from: 我尝试更改application.html.erb ＆ product / index.html.erb中的link_to ：
<%= link_to 'sign in', new_user_session_path %>
to: 至：
<%= link_to 'sign in', :controller => "/products", new_user_session_path %>.
But this just throw up more errors. 但这只会引发更多错误。
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. 有趣的是，在我添加购物车的部分之前，登录功能和路由工作正常，我在上次提交时将其放在application.html.erb中 。 When I remove this partial the routing error disappears but I loose my partial views/cart/_cart.html.erb . 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 。
Below is the console dump from when I try to login & run the rake routes command. 下面是我尝试登录并运行rake routes命令时的控制台转储。 Thanks in advance for taking the time to look at this. 提前感谢您抽出时间来看看这个。

Look more closely at your stack trace: 仔细查看堆栈跟踪：

Found it? 找到了？ The log shows it has rendered a bunch of partials, down to cart/_cart.html.erb . 日志显示它已经呈现了一堆部分，一直到cart/_cart.html.erb 。 It even tells you the error happens on line 49. Now what's on line 49? 它甚至告诉你错误发生在第49行。现在第49行是什么？ This: 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" %>
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. 正如Ryan在下面的评论中正确指出的那样，Rails正在寻找Devise下的部分范围，因为这是你正在渲染的那个。
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. 更简单地说，您可以只为其添加路径名称（您在rake routes找到的路径名称），并为其添加_path以形成URL。 products_path ends up being the URL string for products#index . products_path最终成为products#index的URL字符串。
Which gives in your case 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 %>
Listen to your stack traces, they're talking to you! 听听你的堆栈痕迹，他们正在跟你说话！

Way late to the party, but this was my solution. 方式来晚了，但这是我的解决方案。 Simply prefix the controller as absolute with " / ". 只需在控制器前加上“ / ”作为绝对值。 A little long and ugly, but returns link for a controller/action or a route passed. 有点长而丑，但返回控制器/动作或传递路线的链接。 I use it to build menus driven from sql table. 我用它来构建从sql表驱动的菜单。
# dynamic link_to
def menu_link(params, html_options=nil)
if params[:controller].present?
link_to params[:display], {controller: "/#{params[:controller]}", action: params[:resource]}, default_navigation_options(html_options)
elsif params[:route].present?
link_to params[:display], params[:route], default_navigation_options(html_options)
end
