Symfony - 有没有办法将实体设置为全局？

Question

我有一个实体，我在登录页面上扩展，但在下一页上扩展不存在（实体在两个页面上都存在）。有没有办法让我的扩展在下一页上可用？

<?php
namespace RegistrationExtension\Subscriber;

use ...

class RegisterExtensionSubscriber implements EventSubscriberInterface{
    private $company;

    /**
     * @var EntityRepositoryInterface
     */
    private $mailTypeRepository;

    /**
     * @var EntityRepositoryInterface
     */
    private $mailRepository;
    /**
     * @var EntityRepositoryInterface
     */
    private $customerRepo;

    public function __construct(
        EntityRepositoryInterface $customerRepo,
        EntityRepositoryInterface $mailTypeRepository,
        EntityRepositoryInterface $mailRepository
    ) {
        $this->customerRepo = $customerRepo;
         $this->mailTypeRepository = $mailTypeRepository;
         $this->mailRepository = $mailRepository;
    }
    public static function getSubscribedEvents(): array{
        return [
            AccountLoginPageLoadedEvent::class => 'extendCustomer',
            AccountOverviewPageLoadedEvent::class => 'onCustomRegister'
        ];
    }

当登录页面完成加载时触发此函数。

    public function extendCustomer(AccountLoginPageLoadedEvent $event){
       // if (isset($_POST['submit'])) {
            if(isset($_GET["email"])){
                $company = $_GET["email"];
            }else{
                $company = null;
            }
            $mailEntity = $this->mailTypeRepository->search(
                (new Criteria())->addFilter(new EqualsFilter('mail_template_type.technicalName', "customer_register")),
                $event->getContext()
            );
    
            if ($mailType = $mailEntity->getEntities()->first()) {
                $mailEntity = $this->mailRepository->search(
                    (new Criteria())->addFilter(new EqualsFilter('mail_template.mailTemplateTypeId', $mailType->getId())),
                    $event->getContext()
                );
            
                $mailEntity->getEntities()->first()->addExtension('file_does_exist', new ArrayEntity(['company' => "blub"]));
                dump($mailEntity->getEntities()->first());
            }
       // }
    }

此函数在用户登录并且页面完成加载后触发。

    public function onCustomRegister(AccountOverviewPageLoadedEvent $event){
        $mailEntity = $this->mailTypeRepository->search(
            (new Criteria())->addFilter(new EqualsFilter('mail_template_type.technicalName', "customer_register")),
            $event->getContext()
        );

        if ($mailType = $mailEntity->getEntities()->first()) {
            $mailEntity = $this->mailRepository->search(
                (new Criteria())->addFilter(new EqualsFilter('mail_template.mailTemplateTypeId', $mailType->getId())),
                $event->getContext()
            );
            dump($mailEntity);
          //  $mail = $mailEntity->getEntities()->first()->addExtension('file_does_exist', new ArrayEntity(['company' => $company]));
        }
        $customerEntity = $this->customerRepo->search(
            (new Criteria())->addFilter(new EqualsFilter('customer.customerNumber', $event->getSalesChannelContext()->getCustomer()->getCustomerNumber())),
            $event->getContext()
        );         
    }
}

会不会是AccountOverviewPageLoadedEvent事件加载了beo？

正如您在开发时已经发现的那样，扩展不会持久化。 您想要的是EntityExtension。这样您就可以扩展客户实体。但是，由于只能通过 EntityExtension 添加关联和外键字段，因此您需要一个自己的实体。

假设你是 create a entity: CustomerRegistrationFile 然后，您可以扩展 CustomerDefinition 并将您的 CustomerRegistrationFile 添加为关联。通过这种方式，您可以直接在实体中保存数据，并可以将其加载到您需要的任何地方，例如在您的邮件模板中。

旁注：关联不会自动加载。除了 OneToOneAssociations 可以从一端自动加载。不是两端，以防止循环引用。
