ActiveAdmin：作成/更新後に別のモデルを更新する

Question

これは私がやっていることです。私は現在、その上に多くの部品を持っている機器を持っています。私も部品の在庫があります。私がやってみたいことは、機器に部品を追加するときに、部品を在庫から取り除くときです。私は現在、機器に取り付けられている部品を持っていますが、量を減らす方法はわかりません。ここには、部品と機器の管理モデルがあります。

equipment.rb

ActiveAdmin.register Equipment do 
    permit_params :name, :description, :status, :manufacturer_id, :serial, :category_id, :location_id, part_ids: [] 
    config.per_page = 5 

    filter :status, as: :select, collection: proc { Equipment::STATUS } 
    filter :category, as: :select, collection: proc { Category.all.where('category_id > ?', 0) } 

    index do 
     column("Name", :sortable => :id) {|equipment| link_to "#{equipment.name} ", equipment_path(equipment) } 
     column("Status") {|item| status_tag(item.status, 
      if item.status == 'online' 
       :green 
      else 
       :red 
      end 
     )} 
     column :manufacturer 
     column :serial 
     column :category_id 
     column :location_id 
     actions 
    end 

    show do |equipment| 
     attributes_table do

       column("Quantity In Stock", :qty)

end 

part.rb

ActiveAdmin.register Part do 
    permit_params :username, :name, :description, :sku, :part_url, :qty,

    scope :all, :default => true 

    index do 
     column("Name", :sortable => :id) {|part| link_to "#{part.name} ", part_path(part) }

      f.input :remove_attachment, as: :boolean, required: :false, label: 'Remove Document'

     f.actions 
    end

そしてここでは、各

Answer 1

activeadminでコントローラを作成できます。 part.rbで

：

ActiveAdmin.register Part do 
//the customisation of index, show, form 
    controller do 
    def create 
     @part = Part.new(permitted_params[:part]) 
     // do what you want 
     if @part.save 
     redirect_to admin_parts_path 
     else 
     render :new 
     end 
    end 
    end 
end 

equipment.rbに同じ。それが役に立てば幸い ！
