Question

ActiveAdmin文档说我可以像这样覆盖实用程序导航：

ActiveAdmin.setup do |config|
  config.namespace :admin do |admin|
    admin.build_menu :utility_navigation do |menu|
      menu.add label: "ActiveAdmin.info", url: "http://www.activeadmin.info", html_options: { target: :blank }
      admin.add_logout_button_to_menu menu # can also pass priority & html_options for link_to to use
    end
  end
end

它还说默认显示包括当前用户的电子邮件地址。它是如何获得当前用户的电子邮件地址的？当我尝试用menu.add label替换current_admin_user值时，我收到一条错误消息，指出current_admin_user未定义。如何从配置文件中访问有关当前登录用户的信息？ ActiveAdmin在幕后如何做到这一点？

Answer 1

config.namespace :admin do |admin|
      admin.build_menu :utility_navigation do |menu|
         menu.add  :label  => proc{ display_name current_active_admin_user },
                  :url    =>  proc{  edit_admin_admin_user_path(current_active_admin_user) }  ,#link_to current_active_admin_user,
                  :id     => 'current_user',
                  :if     => proc{ current_active_admin_user? }
        admin.add_logout_button_to_menu menu
      end
    end

Answer 2

试试以下内容：

ActiveAdmin.setup do |config|
  config.namespace :admin do |admin|
    admin.build_menu :utility_navigation do |menu|
      menu.add label: "ActiveAdmin.info", url: "http://www.activeadmin.info",
                                      html_options: { target: :blank }
      admin.add_current_user_to_menu  menu
      admin.add_logout_button_to_menu menu
    end
  end
end
