任何人有任何想法如何解决这个问题？我运行rails g active_admin：安装在父装载引擎目录中，并且文件夹/ mycode/testingengine/app/admin确实存在于默认的仪表板文件中，所以我不知道该从哪里开始。任何帮助非常感谢！

终于搞明白了。在您的ActiveAdmin.setup initalizer块中添加以下内容。

config.load_paths.delete_at(0) 
    config.load_paths << "#{Cms::Engine.root}/app/admin/"

请务必用您的引擎名称替换Cms。现在它不会尝试使用您的引擎文件夹从应用程序加载activeadmin。

如果ActiveAdmin在你父母的发动机配置，并且不想弄乱父应用程序的配置与对孩子的应用程序引用，您可以在安装引擎设置ActiveAdmin负荷页：

module YourEngine 
    class Engine < ::Rails::Engine 

    # ... 

    initializer :divery do |app| 
     ActiveAdmin.application.load_paths << File.join(config.root, 'lib/admin') 
    end 

    # ... 

    end 
end

请注意，重要的是您的ActiveAdmin资源是而不是，其定义见app/，all admin resources should be defined in lib。
