活动管理员:如何自定义主菜单(在页面顶部)？

Question

这可能很简单,但我找不到解决方案.

在ActiveAdmin中,我想自定义页面顶部菜单的行为,特别是当前登录用户的此链接:

在我的所有搜索中,我都找不到改变右上角链接的方法.

我想更改链接指向的文本,并可能添加指向菜单区域的链接.

是否有捷径可寻？

您可以修改config/initializers/active_admin.rb.

对于ActiveAdmin 0.6.0,请添加以下行:

ActiveAdmin.setup do |config|
  # Customize Up Right menu
  config.namespace :admin do |admin|
    admin.build_menu :utility_navigation do |menu|
      menu.add  :label  => 'click me', # text of your link
        :url            => proc{ my_awesome_path }, # route of your link
        :html_options   => {:style => 'float:left;'}, # attributes added in the DOM of your link
        :if             => proc{ 1 < 2 } # condition to display the link

      menu.add  :label  => proc{ display_name current_active_admin_user }, # email of the current admin user logged
        :url            => proc { my_other_awesome_path },
        :html_options   => {:style => 'float:left;'},
        :id             => 'current_user',
        :if             => proc{ current_active_admin_user? }

      admin.add_logout_button_to_menu menu, 100, :style => 'float:left;' # logout link
    end
  end
end

对于ActiveAdmin 0.4.2及之前,您必须在同一文件的末尾添加此代码:

ActiveAdmin.setup do |config|
  # ...
end

module ActiveAdmin
  module Views
    class HeaderRenderer
      alias_method :default_to_html, :to_html
      def to_html
        default_to_html.sub(current_admin_user.email, "<a style='text-decoration: underline;' href='#{my_awesome_path}'>#{current_admin_user.email}</b>").html_safe
      end
    end
  end
end

希望这可以帮助 :)
