ActiveAdmin：在创建/更新后更新另一个模型

问题描述

所以我想做的就是这个。我目前有一件设备，上面有很多零件。我也有零件清单。我要做的是将零件添加到设备后，将其从库存中删除。我目前有零件附在设备上，但不确定如何减少数量。这是零件和设备的管理模型。

So what I am trying to do is this. I currently have a piece of equipment that has many parts on it. I also have an inventory of parts. What I am looking to do is when you add a part to the equipment, it removes it from the inventory. I currently have the parts attaching to the equipment but not sure how to decrease the quantity. Here are the admin models for part and equipment.

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
            row :name
            row :description do |equipment_item|
                raw(equipment_item.description) 
            end
            row :location
            row :status
            row :serial
            row :category
            row :manufacturer
        end

        panel "Parts List" do
            table_for equipment.parts do |parts|
                column("Name", :sortable => :id) {|part| link_to "#{part.name} ", part_path(part) }
                column :sku
                column :location
                column :department
                column("Quantity In Stock", :qty)
            end
        end

        active_admin_comments
    end

    form html: { multipart: true } do |f|
        f.inputs do
          f.input :name, label: "Equipment Name"
          f.input :description, label: "Equipment Description", as: :html_editor
          f.input :serial, label: "Serial"
          f.input :status, :label => 'Status', :as => :select2, :input_html => { :style => 'width:80%' }, collection: Equipment::STATUS if current_user.role == 'admin'
          f.input :manufacturer_id, :label => 'Manufacturer', :as => :select2, :input_html => { :style => 'width:80%' }, :collection => Manufacturer.all.map{|m| ["#{m.name}", m.id]}
          f.input :location_id, :label => 'Location', :as => :select2, :input_html => { :style => 'width:80%' }, :collection => Location.all.map{|l| ["#{l.name}", l.id]}
          f.input :category_id, :label => 'Category', :as => :select2, :input_html => { :style => 'width:80%' }, :collection => Category.all.map{|c| ["#{c.name}", c.id]}
          f.input :parts, :label => 'Parts', :as => :select2_multiple, :input_html => { :style => 'width:80%' }, :collection => Part.all.map{|c| ["#{c.name}", c.id]}
        end
        f.actions
    end

end

part.rb

ActiveAdmin.register Part do
    permit_params :username, :name, :description, :sku, :part_url, :qty, 
                  :attachment, :location_id, :department_id, :remove_attachment, :_wysihtml5_mode

    filter :name
    filter :location
    filter :department

    scope :all, :default => true

    index do
        column("Name", :sortable => :id) {|part| link_to "#{part.name} ", part_path(part) }
        column :sku do |part|
            best_in_place part, :sku, as: :input
        end
        column :qty do |part|
            best_in_place part, :qty, as: :input,
                                :place_holder => "Click To Edit",
                                :html_attrs => { :style => 'width:30%' }
        end
        column :location
        column :department
    end

    show do |parts|
        attributes_table do
            row :name
            row :description do |part|
                raw(part.description) 
            end
            row :location
            row :department
            row :sku
            row :qty
            row("Attached Documents", :sortable => :id) {|part| link_to "#{part.attachment_identifier} ", part.attachment_url }
            row("Part URL", :sortable => :id) {|part| link_to "#{part.part_url} ", part.part_url }
        end
        active_admin_comments
    end

    form :html => { :enctype => "multipart/form-data" } do |f|
        f.inputs do
          f.input :name, label: "Part Name"
          f.input :description, label: "Part Description", as: :html_editor
          f.input :sku, label: "Part SKU"
          f.input :qty
          f.input :part_url, label: "Part URL"
          f.input :department_id, :label => 'Department', :as => :select2, :input_html => { :style => 'width:80%' }, :collection => Department.all.map{|d| ["#{d.name}", d.id]}
          f.input :location_id, :label => 'Location', :as => :select2, :input_html => { :style => 'width:80%' }, :collection => Location.all.map{|l| ["#{l.name}", l.id]}
          f.input :attachment, :as => :file, :hint => "Current Document: " + 
            if f.object.attachment_identifier
                f.object.attachment_identifier
            else
                ""
            end
          f.input :remove_attachment, as: :boolean, required: :false, label: 'Remove Document'
        end
        f.actions
    end
end

这是每个模型的

任何帮助都将不胜感激。

Any help is greatly appreciated.

推荐答案

您可以在activeadmin中创建一个控制器。

You can create a controller in activeadmin.

在part.rb中：

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

对于equipment.rb同样。希望对您有所帮助！

the same for equipment.rb. Hope it helps !
