为什么devise将/ devise /放在每个link_to锚的前面？

如何解决为什么devise将/ devise /放在每个link_to锚的前面？

| 我刚刚生成了所有供设计的视图，并且我开始自定义登录屏幕。它非常有用，除了登录页面上生成的所有链接均以\“ / devise \”开头的链接之外。 为什么这样做呢？似乎是奇怪的默认行为 如何阻止将/ devise添加到每个link_to（）？ 我的路线文件：

devise_for :users

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

root :to => \"webpages#index\"

我的“耙路”

        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devise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?\",:page => \"why\") %>

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

解决方法

在新版本的Rails中，您可以执行以下操作：

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

您只需将_path附加到在执行“耙路”时看到的命名路由即可。将_url附加到命名路由后，将获得URL字符串BTW。这可能是有用的。 ian。     ,我终于想通了。

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

基本上，我所做的是使用\“ / webpages \”而不是\“ webpages \”告诉Rails这些控制器不在\“ devise \”名称空间或父目录下。 这是适当的解决方法吗？有没有更简单的解决方案？     ,所有旨在进行设计的链接/表单都应以\“ / devise \”开头。请参阅下面的devise生成的路线。为什么要更改此行为？它不起作用吗？还是您需要/想要自定义设计控制器？
