Magento2カスタム注文属性の追加

Magentoの注文にカスタム属性を追加するにはどうすればよいですか。製品と顧客にとっては明らかなようですが、注文に追加の属性を追加するための情報が見つかりません。

独自のモジュールを作成し、セットアップを作成します/InstallData.php

<?php



namespace Own\Module\Setup;

use Magento\Customer\Model\Customer;
use Magento\Framework\Encryption\Encryptor;
use Magento\Framework\Indexer\IndexerRegistry;
use Magento\Framework\Setup\UpgradeDataInterface;
use Magento\Framework\Setup\ModuleContextInterface;
use Magento\Framework\Setup\ModuleDataSetupInterface;
use Magento\Eav\Setup\EavSetup;
use Magento\Eav\Setup\EavSetupFactory;
use Magento\Framework\Setup\InstallDataInterface;
use Magento\Catalog\Setup\CategorySetupFactory;
use Magento\Quote\Setup\QuoteSetupFactory;
use Magento\Sales\Setup\SalesSetupFactory;

/**
 * @codeCoverageIgnore
 */
class InstallData implements InstallDataInterface
{
    /**
     * EAV setup factory
     *
     * @var EavSetupFactory
     */
    private $eavSetupFactory;

    /**
     * Category setup factory
     *
     * @var CategorySetupFactory
     */
    protected $categorySetupFactory;

    /**
     * Quote setup factory
     *
     * @var QuoteSetupFactory
     */
    protected $quoteSetupFactory;

    /**
     * Sales setup factory
     *
     * @var SalesSetupFactory
     */
    protected $salesSetupFactory;


    /**
     * Init
     *
     * @param CategorySetupFactory $categorySetupFactory
     * @param SalesSetupFactory $salesSetupFactory
     */
    public function __construct(
        SalesSetupFactory $salesSetupFactory
    ) {
        $this->salesSetupFactory = $salesSetupFactory;
    }

    /**
     * {@inheritdoc}
     * @SuppressWarnings(PHPMD.ExcessiveMethodLength)
     */
    public function install(ModuleDataSetupInterface $setup, ModuleContextInterface $context)
    {

        /** @var \Magento\Sales\Setup\SalesSetup $salesSetup */
        $salesSetup = $this->salesSetupFactory->create(['setup' => $setup]);


        /**
         * Remove previous attributes
         */
        $attributes =       ['NEW_ATTRIBUTE'];
        foreach ($attributes as $attr_to_remove){
            $salesSetup->removeAttribute(\Magento\Sales\Model\Order::ENTITY,$attr_to_remove);

        }



        /**
         * Add 'NEW_ATTRIBUTE' attributes for order
         */
        $options = ['type' => 'varchar', 'visible' => false, 'required' => false];
        $salesSetup->addAttribute('order', 'NEW_ATTRIBUTE', $options);

    }
}

また、同じ構造を使用してアイテムに新しい属性を割り当てることもできます。@RiccardoTあなたにも

編集：新しい属性に値を挿入する方法（私はcronジョブであるModel / Orders.phpでこれを使用します）：

use Magento\Directory\Model\Currency;
use Magento\Framework\Api\AttributeValueFactory;
use Magento\Framework\Exception\NoSuchEntityException;
use Magento\Framework\Pricing\PriceCurrencyInterface;
use Magento\Sales\Api\Data\OrderInterface;
use Magento\Sales\Api\Data\OrderStatusHistoryInterface;
use Magento\Sales\Model\Order\Payment;
use Magento\Sales\Model\ResourceModel\Order\Address\Collection;
use Magento\Sales\Model\ResourceModel\Order\Creditmemo\Collection as CreditmemoCollection;
use Magento\Sales\Model\ResourceModel\Order\Invoice\Collection as InvoiceCollection;
use Magento\Sales\Model\ResourceModel\Order\Item\Collection as ImportCollection;
use Magento\Sales\Model\ResourceModel\Order\Payment\Collection as PaymentCollection;
use Magento\Sales\Model\ResourceModel\Order\Shipment\Collection as ShipmentCollection;
use Magento\Sales\Model\ResourceModel\Order\Shipment\Track\Collection as TrackCollection;
use Magento\Sales\Model\ResourceModel\Order\Status\History\Collection as HistoryCollection;

class Orders
{

    /**
     * @param \Magento\Sales\Model\Order $order
     */

    public function __construct(
        \Magento\Sales\Model\Order $order,
        \Psr\Log\LoggerInterface $loggerInterface,
        \Magento\Sales\Api\OrderRepositoryInterface $orderRepositoryInterface
    ) {

        $this->order = $order;
        $this->logger = $loggerInterface;
        $this->orderRepository = $orderRepositoryInterface;
    }

    public function execute(){

       $order = $this->order->loadByIncrementId($incrementId);
       $order->setNewAttribute('NEW VALUE');
       $order->save();
   }
}

これは一般に、注文にアクセスして属性に値を設定する方法です。
