ruby-on-rails – 使用active_model_serializers序列化一组模型

#app/serializers/admin_serializer.rb
class AdminSerializer < ActiveModel::Serializer
  attributes :id,:email,:access_locked?
end


#app/controllers/dashboard/admins_controller.rb
  def index
    @search = Admin.search(params[:q])
    @admins = @search.result(:distinct => true).page(params[:page]).per(10)

    @page_entries_info = view_context.page_entries_info @admins
    # render json: @admins
    respond_to do |format|
      format.html
      format.js
      format.json {render json: @admins}
    end
  end



#app/views/dashboard/admins/index.html.erb
  <%= debug (ActiveModel::Serializer::Adapter.adapter_class(:json_api).new(ActiveModel::Serializer.serializer_for(@admins.first).new(@admins.first),{}).to_json) %>
  <%= debug (@admins.all.map{|admin| AdminSerializer.new(admin).to_json}) %>

以上调试产生以下响应：

--- '{"data":{"id":"1","type":"admins","attributes":{"email":"tech@bluesapling.com","access_locked?":false}}}' //returned by the first debug

在第一个调试中,我只序列化一个对象,而在第二个调试中,我正在尝试为一个对象数组执行此操作.
第一个调试正确地返回对象的序列化版本(以json_api格式),而第二个调试则没有.
尝试使用ArraySerializer,但没有成功：ActiveModel :: Serializer :: ArraySerializer.new(@admins,each_serializer：AdminSerializer).as_json
如何实现所需的序列化.而且,如果实现了,我可以使用其他一些简化版吗？因为这个调试语句太冗长了.

尝试了这里提到的所有解决方案 – How do you initialize an ActiveModel::Serializer class with an ActiveRecord::Relation array?

我试图解决的基本问题是,在Admin控制器的索引方法中,Admin对象作为PORO传递给index.html文件.但我想要这个对象的序列化json版本,以便我可以将它作为prop传递给我的react组件

index方法在http://dashboard.localhost.com:3000/admins.json发射时渲染正确的json

索引方法更新#1

def index
    @search = Admin.search(params[:q])
    @admins_array = @search.result(:distinct => true).to_a
    if params[:page]
      @admins = @search.result(:distinct => true).page(params[:page][:number]).per(10)
      @admins_json_array = Kaminari.paginate_array(@admins_array).page(params[:page][:number]).per(10)
    else
      @admins = @search.result(:distinct => true).page(1).per(10)
      @admins_json_array = Kaminari.paginate_array(@admins_array).page(1).per(10)
    end
    @admins_json = ActiveModel::SerializableResource.new(@admins_json_array.to_a)
    ...
    ...
    ...
end
