我有这条路线

profile GET /contacts/:id(.:format) {:controller=>"my_devise/contacts", :action=>"profile"}

这是我的控制器/application_controller.rb

class ApplicationController < ActionController::Base
  protect_from_forgery

  before_filter :get_current_user

    def get_current_user
        @current_user = current_user
    end

end

<%= link_to "Profile", profile_path(@current_user) %>如果我在 url 上的view/layouts/application.html.erb 文件中有此链接，我http://localhost:3000/contacts/1没有错误，但如果我尝试点击 url http://localhost:3000/contacts，我会收到以下错误

Routing Error

No route matches {:controller=>"my_devise/contacts", :action=>"profile"}

如果我删除 application.html.erb 文件中的链接并点击http://localhost:3000/contacts，错误就会消失。

为什么该链接会导致此错误？

要回答您的实际问题，这是因为您没有针对该问题的路线（/contacts- 请注意没有 id）。您的路线是/contacts/:id(.:format)- 格式是可选的，但 id 不是。您还需要将 id 设为可选，或创建另一条路线。

路线是这样的

联系人 GET /contacts(.:format) {:action=>"list", :controller=>"my_devise/contacts"}

在这里，我们还必须给出格式。如果我们提供联系人，它将引发路由错误。所以也请输入格式。
