OroPlatform执行迁移时报attachmentExtension为null的问题解决

我需要给oro_brand添加Image属性，参考官方配置文档完成代码开发后，执行迁移命令时出现报错。

报错信息 #

执行bin/console oro:migration:load --force -vvv时抛出如下错误：

Process migrations...
  > Oro\Bundle\EntityExtendBundle\Migration\LoadEntityConfigStateMigration
  > Test\Bundle\BrandBundle\Migrations\Schema\TestBrandBundleInstaller

In AddLogoToBrand.php line 42:
                                                           
  [Symfony\Component\Debug\Exception\FatalThrowableError]  
  Call to a member function addImageRelation() on null  

报错显示$this->attachmentExtension值为null，但代码写法完全遵循官方规范和已有厂商实现示例，相关代码如下：

//src/Test/Bundle/BrandBundle/Migrations/Schema/v1_0/AddLogoToBrand.php

use Doctrine\DBAL\Schema\Schema;
use Oro\Bundle\AttachmentBundle\Migration\Extension\AttachmentExtensionAwareInterface;
use Oro\Bundle\AttachmentBundle\Migration\Extension\AttachmentExtensionAwareTrait;
use Oro\Bundle\EntityExtendBundle\EntityConfig\ExtendScope;
use Oro\Bundle\MigrationBundle\Migration\Migration;
use Oro\Bundle\MigrationBundle\Migration\OrderedMigrationInterface;
use Oro\Bundle\MigrationBundle\Migration\QueryBag;

class AddLogoToBrand implements Migration, OrderedMigrationInterface, AttachmentExtensionAwareInterface
{
    use AttachmentExtensionAwareTrait;

    public const LOGO_SIZE = 10;
    public const BRAND_TABLE = 'oro_brand';
    public const FIELD_NAME = 'logo';

    /**
     * {@inheritdoc}
     */
    public function getOrder(): int
    {
        return 10;
    }

    /**
     * {@inheritdoc}
     */
    public function up(Schema $schema, QueryBag $queries): void
    {
        $this->addLogoBrandAssociation($schema);
    }

    /**
     * @param Schema $schema
     */
    public function addLogoBrandAssociation(Schema $schema)
    {
        $this->attachmentExtension->addImageRelation(
            $schema,
            self::BRAND_TABLE,
            self::FIELD_NAME,
            [
                'extend' => ['owner' => ExtendScope::OWNER_CUSTOM]
            ],
        );
    }

解决方案 #

删除自定义的TestBrandBundleInstaller后，迁移命令即可正常运行。
