Ruby on rails ActiveAdmin注释作为提交系统

我有一个符合hippa的应用程序，我正在开发，作为其中的一部分，我想使用AA注释作为嵌套的资源/提交系统；如果没有注释，则应拒绝创建或更新。我有其他嵌套资源工作（包括嵌套在嵌套资源中保存）；以下内容适用于更新，但不适用于新建-在新建时，我收到一个错误，comments.resource不能为空

我已经在许可参数中获得了注释属性；这里是admin/prescription.rb：

ActiveAdmin.register Prescription do

    menu :parent => "Treatments", :priority => 2

    permit_params :treatment_id, :hours, :summary, :product_id, :prescription_date, prescribed_tensions_attributes: [:id, :location, :force, :position, :prescription_id, :created_at, :_destroy], comments_attributes: [:id, :namespace, :body, :resource_id, :resource_type, :author_id, :author_type]


    before_filter :only => [:show, :destroy, :edit, :update] do
        # @prescription = Prescription.unscoped.includes(:prescribed_tensions).find(params[:id])
        @prescription = Prescription.unscoped.includes(:product, :prescribed_tensions, :patient, :doctors).find(params[:id])
    end




    form do |f|
        f.inputs "Prescribed Dose" do
            f.input :treatment, :as => :select, input_html: {class: 'select2able'}
            f.input :prescription_date,  as: :date_time_picker
            f.input :hours
            f.input :summary, :as => :rich, :config => { :width => '79%', :height => '150px' }

            f.has_many :prescribed_tensions, :allow_destroy => true do |g|
                g.input :location, :as => :select,  input_html: {class: 'select2able'}, collection: BaseProduct.locations

                g.input :position
            end
        end

        f.inputs "Add A Comment" do
            f.semantic_fields_for :comments, ActiveAdmin::Comment.new do |c|
                c.inputs :class => "" do

通过以上内容，我得到：

  #<Prescription:0x007fb402700f90
   id: nil,
   hours: 12,
   summary: "",
   prescription_date: Mon, 15 May 2017 09:31:00 EDT -04:00,
   created_at: nil,
   updated_at: nil,
   treatment_id: 6>,
 @details={:"comments.resource"=>[{:error=>:blank}]},
 @messages={:"comments.resource"=>["can't be blank"]}>

#，
@详细信息={：“comments.resource”=>[{:error=>:blank}]}，
@messages={：“comments.resource”=>[“不能为空”]}>

我也在尝试手动操作（即@prescription=prescription.new（允许的参数[：prescription]）并对building@comment执行相同的操作，但即使我正在设置

@comment.resource=@prescription--我仍然无法保存@prescription，因为comments.prescription为空；因为@prescription尚未保存

---

我确信我遗漏了一些可笑的东西，但不确定这可能是什么？

对于那些关心此事的人，以下是我如何修复上述问题的；我成功地保存到了索引页（因为HIPA资源是空白的）而不是显示页面。我还没有实现用于删除的弹出式注释文本输入。我还为任何资源编写了以下通用内容——希望能够覆盖一些AA资源（不是全部）并在共享代码中实现，但也无法理解
