ActiveAdmin 未保存 has_many 嵌套对象

ActiveAdmin not saving has_many nested object

我似乎无法找出为什么我的 has_many 记录无法保存。我已经在模型中使用 has_one 进行了测试,它工作正常,但是当我将其更改为 has_many 时,它不起作用。我检查了一些类似的 Whosebug 帖子,我似乎有这个正确但它不起作用。 Nested form in activeadmin not saving updates & ActiveAdmin Form not saving nested object

这是 Rails version 5.1.0.alphaActiveadmin version 1.0.0.pre4

我没有收到任何错误,也没有看到嵌套对象被创建,尽管我在创建对象时看到了参数,这里是输出

更新

我刚刚在 rails 控制台中进行了测试,它工作正常(仍然无法通过 ActiveAdmin 浏览器工作

    2.3.0 :001 > params = {"name"=>"test district", "title"=>"", "sub_title"=>"", "paragraph"=>"", "sections_attributes"=>{"0"=>{"text"=>"test section"}}}
 => {"name"=>"test district", "title"=>"", "sub_title"=>"", "paragraph"=>"", "sections_attributes"=>{"0"=>{"text"=>"test section"}}} 
2.3.0 :002 > d = AbqDistricts::District.create(params)
   (0.2ms)  BEGIN
  SQL (0.5ms)  INSERT INTO "abq_districts_districts" ("name", "title", "sub_title", "paragraph", "created_at", "updated_at") VALUES (, , , , , ) RETURNING "id"  [["name", "test district"], ["title", ""], ["sub_title", ""], ["paragraph", ""], ["created_at", "2016-12-05 18:58:02.973482"], ["updated_at", "2016-12-05 18:58:02.973482"]]
  SQL (2.2ms)  INSERT INTO "abq_districts_sections" ("text", "abq_districts_district_id", "created_at", "updated_at") VALUES (, , , ) RETURNING "id"  [["text", "test section"], ["abq_districts_district_id", 63], ["created_at", "2016-12-05 18:58:02.979025"], ["updated_at", "2016-12-05 18:58:02.979025"]]
   (0.4ms)  COMMIT
 => #<AbqDistricts::District id: 63, name: "test district", title: "", sub_title: "", paragraph: "", created_at: "2016-12-05 18:58:02", updated_at: "2016-12-05 18:58:02"> 

我可以通过添加 ActiveAdmin.register

进行修补
controller do
    def create
      @section = AbqDistricts::District.create!(permitted_params[:abq_district].as_json)
      redirect_to admin_faq_sections_path, notice: "Section was successfully created!"
    end
end

这只是一个补丁。注意,唯一有效的方法是如果我使用 .as_json 它不适用于 to_json 或单独使用参数
