ActiveAdmin不保存has_many嵌套对象

我似乎无法找出为什么我的has_many记录不会保存。 我在模型中使用has_one进行测试并且它工作正常，但是当我将其更改为has_many它不起作用。 我检查了几个类似的stackoverflowpost，我似乎有这个正确，但它不起作用。 activeadmin中的嵌套表单不保存更新和ActiveAdmin表单不保存嵌套对象

这适用于Rails version 5.1.0.alpha和Activeadmin version 1.0.0.pre4

我没有得到任何错误，也没有看到嵌套对象被创建虽然我在这里创建一个对象时看到params是输出

这是我的信息

ActiveAdmin.register

abq_districts.rb

 module AbqDistricts def self.table_name_prefix 'abq_districts_' end end 

district.rb

 class AbqDistricts::District < ApplicationRecord has_many :sections, foreign_key: :abq_districts_district_id accepts_nested_attributes_for :sections, allow_destroy: true end 

section.rb

 class AbqDistricts::Section < ApplicationRecord belongs_to :abq_districts_district validates_presence_of :abq_districts_district end 

UPDATE

我只是在rails控制台上测试它运行良好（仍然无法通过ActiveAdmin浏览器工作

Answer 1

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。 注意并且它唯一的工作方式是如果我使用.as_json它不能用于to_json或只用params
