Rails Engine with ActiveAdmin 中的资源命名空间问题

Question

我在 ActiveAdmin 中成功注册资源时遇到问题，但无法创建或更新任何记录。我认为这是由于命名空间问题。我可以在注册资源时使用选项覆盖它吗？

我正在构建一个 Rails 引擎，它从引擎内部注册 AA 资源。我按照说明 here.

我的引擎包含 lib/admin/myengine/myresources.rb

if defined?(ActiveAdmin)
  ActiveAdmin.register Myengine::Myresource do
  end
end

在 test/dummy 应用程序中，相关架构如下所示：

create_table "myengine_myresources", force: :cascade do |t|
  t.string   "name"
  t.datetime "created_at", null: false
  t.datetime "updated_at", null: false
end

当我运行虚拟应用程序服务器时，我成功导航到 http://localhost:3000/admin/myengine_myresources 并单击 'New Myengine Myresource'

我输入名称并单击 'Create Myresource'，但它会将该请求视为我提交了空白属性值。

服务器日志显示：

Started POST "/admin/myengine_myresources" for ::1 at 2015-12-02 11:13:52 -0800
Processing by Admin::MyengineMyresourcesController#create as HTML
  Parameters: {"utf8"=>"✓", "authenticity_token"=>"stuff", "myresource"=>{"name"=>"Arbitrary Name"}, "commit"=>"Create Myresource"}

   (0.1ms)  rollback transaction
  Rendered /Users/me/.rvm/gems/ruby-2.2.3/gems/activeadmin-1.0.0.pre2/app/views/active_admin/resource/new.html.arb (190.7ms)
Completed 200 OK in 231ms (Views: 199.4ms | ActiveRecord: 0.2ms)

我的工作理论是参数需要在 :myengine_myresource 而不仅仅是 :myresource.

关于如何让它发挥作用有什么想法吗？

这是一种解决方法：

if defined?(ActiveAdmin)
  ActiveAdmin.register Myengine::Myeresource do
    controller do
      def permitted_params
        params[:myengine_myresource] = params.delete :myresource
        params.permit(myengine_myresource: [:my, :list, :of, :accepted, :params])
      end
    end
  end
end
