Question

我想知道如何在注册和登录页面上隐藏菜单。我得到了这个代码。问题是Devise gem没有控制器，我可以隐藏菜单。那么，最好的方法是什么？

application.html.haml

- if user_signed_in?
    %nav.navigation
       %ul
         %li
            = link_to "New project", new_place_path
         %li
            = link_to "Profile"
         %li
            = link_to "Sign Out", destroy_user_session_path, method: :delete
- else
     %nav.navigation_welcome
      .inner
         %ul
            %li
               = link_to "Login", new_user_session_path
            %li
               = link_to "Sign up", new_user_registration_path

对于注册\登录，我使用设计。

您可以按照here所述覆盖设计控制器。在那里，您可以指定不包含导航栏的布局

或者如果您只想处理视图图层，可以查看controller_name：

- if user_signed_in?
    %nav.navigation
       %ul
         %li
            = link_to "New project", new_place_path
         %li
            = link_to "Profile"
         %li
            = link_to "Sign Out", destroy_user_session_path, method: :delete
- elsif include_navbar?
     %nav.navigation_welcome
      .inner
         %ul
            %li
               = link_to "Login", new_user_session_path
            %li
               = link_to "Sign up", new_user_registration_path

然后在你的应用程序助手中：

def include_navbar?
  controller_name != 'sessions' && controller_name != 'registrations'
end

如何隐藏特定页面的菜单，如注册和登录？
