Php 附加用户实体时用户名的Uniquentity不起作用

我有一个公司实体的表单，我想在这里为这个公司创建一个管理员用户。 在这个表单中，当创建相同的用户名时，我需要处理重复的条目

Uniquentity可以在单独的用户表单上创建用户，但不能在公司表单上工作

User.php

...
use Symfony\Bridge\Doctrine\Validator\Constraints\UniqueEntity;

/**
 * @ORM\Entity(repositoryClass="App\Repository\UserRepository")
 * @ORM\Table(name="`user`")
 * @UniqueEntity("username", message="This username is already in use.")
 */
class User implements UserInterface
{
    /**
     * @ORM\Id()
     * @ORM\GeneratedValue()
     * @ORM\Column(type="integer")
     */
    private $id;

    /**
     * @ORM\Column(type="string", length=180, unique=true)
     */
    private $username;


    /**
     * @ORM\ManyToOne(targetEntity=Company::class, inversedBy="users")
     */
    private $company;
    
    ...

}

我如何处理这个问题？

根据我的经验，我用以下方式解决了我的问题：

ComapnyController.php：

public function new(Request $request, UserPasswordEncoderInterface $encoder, ValidatorInterface $validator): Response
    {
        $company = new Company();
        $form = $this->createForm(CompanyType::class, $company);
        $form->handleRequest($request);

        if ($form->isSubmitted() && $form->isValid()) {
            $entityManager = $this->getDoctrine()->getManager();

            $user = new User();
            $user->setUsername($form['user']['username']->getData())
                ->setPassword($encoder->encodePassword($user, $form['user']['password']->getData()))
                ->setRoles(array('ROLE_COMPANY_ADMIN'));

            $errors = $validator->validate($user);

            if (count($errors) > 0) {
                return $this->render('company/new.html.twig', [
                    'username' => $form['user']['username']->getData(),
                    'company' => $company,
                    'form' => $form->createView(),
                    'errors' => $errors,
                ]);
            }

            $entityManager->persist($user);

            $company->addUser($user);
            $entityManager->persist($company);
            $entityManager->flush();

            return $this->redirectToRoute('company_index');
        }

        return $this->render('company/new.html.twig', [
            'username' => '',
            'company' => $company,
            'form' => $form->createView(),
            'errors' => '',
        ]);
    }

基于此，我通过以下方式解决了我的问题：

ComapnyController.php：

public function new(Request $request, UserPasswordEncoderInterface $encoder, ValidatorInterface $validator): Response
    {
        $company = new Company();
        $form = $this->createForm(CompanyType::class, $company);
        $form->handleRequest($request);

        if ($form->isSubmitted() && $form->isValid()) {
            $entityManager = $this->getDoctrine()->getManager();

            $user = new User();
            $user->setUsername($form['user']['username']->getData())
                ->setPassword($encoder->encodePassword($user, $form['user']['password']->getData()))
                ->setRoles(array('ROLE_COMPANY_ADMIN'));

            $errors = $validator->validate($user);

            if (count($errors) > 0) {
                return $this->render('company/new.html.twig', [
                    'username' => $form['user']['username']->getData(),
                    'company' => $company,
                    'form' => $form->createView(),
                    'errors' => $errors,
                ]);
            }

            $entityManager->persist($user);

            $company->addUser($user);
            $entityManager->persist($company);
            $entityManager->flush();

            return $this->redirectToRoute('company_index');
        }

        return $this->render('company/new.html.twig', [
            'username' => '',
            'company' => $company,
            'form' => $form->createView(),
            'errors' => '',
        ]);
    }
