为什么 devise 将 /devise/ 放在每个 link_to 锚点前面？

Question

我刚刚生成了设计的所有视图，并且开始自定义登录屏幕。除了登录页面上生成的所有以“/devise”开头的链接之外，它的效果很好。

1. 它为什么要这么做？看起来很奇怪的默认行为
2. 如何阻止它向每个 link_to() 添加 /devise？

我的路线文件：

devise_for :users

get "/webpages/:page" => "webpages#show", :as => :show_webpage

root :to => "webpages#index"

我的“rake 路线”

        new_user_session GET    /users/sign_in(.:format)       {:action=>"new", :controller=>"devise/sessions"}
            user_session POST   /users/sign_in(.:format)       {:action=>"create", :controller=>"devise/sessions"}
    destroy_user_session GET    /users/sign_out(.:format)      {:action=>"destroy", :controller=>"devise/sessions"}
           user_password POST   /users/password(.:format)      {:action=>"create", :controller=>"devise/passwords"}
       new_user_password GET    /users/password/new(.:format)  {:action=>"new", :controller=>"devise/passwords"}
      edit_user_password GET    /users/password/edit(.:format) {:action=>"edit", :controller=>"devise/passwords"}
                         PUT    /users/password(.:format)      {:action=>"update", :controller=>"devise/passwords"}
cancel_user_registration GET    /users/cancel(.:format)        {:action=>"cancel", :controller=>"devise/registrations"}
       user_registration POST   /users(.:format)               {:action=>"create", :controller=>"devise/registrations"}
   new_user_registration GET    /users/sign_up(.:format)       {:action=>"new", :controller=>"devise/registrations"}
  edit_user_registration GET    /users/edit(.:format)          {:action=>"edit", :controller=>"devise/registrations"}
                         PUT    /users(.:format)               {:action=>"update", :controller=>"devise/registrations"}
                         DELETE /users(.:format)               {:action=>"destroy", :controller=>"devise/registrations"}
            show_webpage GET    /webpages/:page(.:format)      {:controller=>"webpages", :action=>"show"}
                    root        /(.:format)                    {:controller=>"webpages", :action=>"index"}

当我尝试渲染来自设计控制器的页面时收到的错误消息：

ActionController::RoutingError in Devise/sessions#new

Showing /home/egervari/Projects/training/app/views/layouts/application.html.erb where line #21 raised:

No route matches {:controller=>"devise/webpages", :action=>"show", :page=>"tour"}

Extracted source (around line #21):

18:           </a>
19:         </li>
20:         <li>
21:           <%= link_to("Tour", :controller => "webpages", :action => "show", :page => "tour") %>
22:         </li>
23:         <li>
24:           <%= link_to("Why Use Us?", :controller => "webpages", :action => "show", :page => "why") %>

如您在上面看到的，它正在尝试将“devise/”添加到我的链接。这根本不是我想要的。

Answer 1

我终于明白了。

      <li><%= link_to("Terms and Use", :controller => "/webpages", :action => "show", :page => "terms") %> |</li>
      <li><%= link_to("Privacy Policy", :controller => "/webpages", :action => "show", :page => "privacy") %> |</li>

基本上我所做的就是放置“/webpages”而不是“webpages”来告诉rails这些控制器不在“devise”命名空间或父目录下。

这是适当的修复吗？有更简单的解决方案吗？

Answer 2

在较新版本的 Rails 中，您可以执行以下操作：

<%= link_to "Privacy Policy", show_webpage_path(:page => 'privacy') %>

只需将 _path 附加到执行“rake 路线”时看到的命名路线即可。顺便说一句，将 _url 附加到命名路由将为您提供 URL 字符串。这可能很有用。

伊恩。

Answer 3

所有针对 devise 的链接/表单均应以“/devise”开头。请参阅下面由 devise 生成的路由。为什么你想改变这种行为？是不是不起作用？或者您需要/想要定制设备控制器吗？
