ActiveAdmin not saving has_many nested object

Question

I cannot seem to find out why my has_many record will not save. I've test with has_one in the models and it works fine but when I change it to has_many it doesn't work. I've check a few simular stackoverflow posts and I seem to have this correct but it doesn't work. Nested form in activeadmin not saving updates & ActiveAdmin Form not saving nested object

This is for Rails version 5.1.0.alpha and Activeadmin version 1.0.0.pre4

I do not get any errors nor do I see the nested object get created though I see the params when I create an object here is the output

here is my info

ActiveAdmin.register

ActiveAdmin.register AbqDistricts::District, as: 'ABQ Districts' do
    permit_params :name, :title, :sub_title, :paragraph, sections_attributes: [ :text, :_destroy ]

    index do
        selectable_column
        id_column
        column :name
        column :title
        column :sub_title

        actions
    end

      filter :name
      filter :title
      filter :updated_at
      filter :created_at

    form do |f|
        f.inputs "Admin Details" do
            f.input :name
            f.input :title
            f.input :sub_title
            f.input :paragraph    

            f.inputs do 
                f.has_many :sections, heading: 'Sections', allow_destroy: true, new_record: true do |a|
                    a.input :text
                end
            end
        end
        f.actions
    end
end

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

I just testing in the rails console and it worked fine (still does not work through ActiveAdmin browser

probably, the reason of your problem is that you're using f.inputs wrapper for has_many relation, that breaks the awaited by AA structure — sadfuzzy

I was able to patch by adding in ActiveAdmin.register

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

This is just a patch. Notice and the only way it worked is if I used .as_json it would not work with to_json or just the params alone
