这个问题出现在 Symfony 5 上。我使用 EasyAdmin v3 包创建了站点的管理端。当我尝试添加实现时出现我的问题，它给了我以下错误消息。

它说我的用户不能为空，但问题是我正在尝试使用管理员帐户添加实现，因此我希望他们考虑到我以管理员身份登录并将自己从该帐户中实现。下面是我的代码我的实现实体。

我的实现CrudController

use EasyCorp\Bundle\EasyAdminBundle\Field\TextField;
use EasyCorp\Bundle\EasyAdminBundle\Field\TextEditorField;
use EasyCorp\Bundle\EasyAdminBundle\Field\IdField;
use EasyCorp\Bundle\EasyAdminBundle\Field\TextareaField;
use Symfony\Component\Form\Extension\Core\Type\DateTimeType;
use Symfony\Component\Validator\Constraints\DateTime;
use Vich\UploaderBundle\Form\Type\VichFileType;

class RealisationCrudController extends AbstractCrudController
{
    public static function getEntityFqcn(): string
    {
        return Realisation::class;

    }

    public function configureFields(string $pageName): iterable
    {

        return [
            IntegerField::new('id','ID')->onlyOnIndex(),
            TextField::new('nom'),
            TextEditorField::new('description'),
            DateTimeField::new('createdAt'),
            DateTimeField::new('dateRealisation'),
            TextField::new('slug'),
           BooleanField::new('portfolio'),
            TextareaField ::new('imageFile')
                ->setFormType(VichFileType::class)
                ->setLabel('Image'),


        ];
    }
}

您是否希望用户始终是登录创建您的Realisation实体的用户？

实现此目的的一种简单方法是使用事件自动将用户设置为您的登录用户。

一个例子是使用 EventSubscriber：

class DoctrineSubscriber implements EventSubscriber

    private $tokenStorage;

    public function __construct(
        TokenStorageInterface $tokenStorage
    ) {
        $this->tokenStorage = $tokenStorage;
    }

    public function getSubscribedEvents(): array
    {
        return [
            Events::prePersist => 'prePersist',
        ];
    }

    public function prePersist(OnFlushEventArgs $args)
    {
       $entity = $args->getObject();

        if ($entity instanceof Realisation) {
            $user = $this->tokenStorage->getToken()->getUser();
            if($user){
                $entity->setUser($user);
            }else{
                //throw an exception, no user logged in
            }
            
        }
    }

}

并且不要忘记在 services.yaml 中定义您的事件订阅者

  #services.yaml
  App\EventSubscriber\DoctrineSubscriber:
    tags:
      - { name: doctrine.event_subscriber }

另一种方法是从您的 EasyAdmin AbstractCrudController 覆盖 createEntity 方法：

public function createEntity(string $entityFqcn)
{
    $realisation = new Realisation();
    
    $realisation->setUser($this->getUser());

    return $realisation;
}
