Symfony-关联字段的“实体”类型的期望值改为“字符串”

Question

我有一个 UserEntity ，其中包含用户的电子邮件地址和密码。然后，一个 UserInstanceEntity 包含用户的电话号码以及 PreferredContactEntity 上的ManyToOne关系，该关系允许用户选择自己喜欢的联系方式。

我希望当用户更改个人资料时，他也可以修改他的电话号码和首选的联系方式。因此，在控制器中，我插入了 UserType 和 UserInstanceType 。

当我发送表格时，出现错误：

  

关联的类型为“ App \ Entity \ PreferredContact”的期望值   字段“ App \ Entity \ UserInstance＃$ preferredContact”中，获得了“字符串”   代替。

UserEntity：

<?php

namespace App\Entity;

use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\Security\Core\User\UserInterface;
use App\Validator\Constraints as AssertPerso;
use DateTime;
use DateTimeInterface;

/**
 * @ORM\Entity(repositoryClass="App\Repository\UserRepository")
 * @ORM\Table(name="app_user")
 * @ORM\HasLifecycleCallbacks()
 */
class User implements UserInterface
{
    /**
     * @ORM\Id()
     * @ORM\GeneratedValue()
     * @ORM\Column(type="integer")
     */
    private $id;

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

    /**
     * @ORM\Column(type="array")
     */
    private $roles = [];

    /**
     * @var string plain password
     */
    private $plainPassword;

    /**
     * @ORM\Column(type="boolean")
     */
    private $enabled;

    /**
     * @var string The hashed password
     * @ORM\Column(type="string")
     */
    private $password;
...

UserInstanceEntity：

<?php

namespace App\Entity;

use Doctrine\ORM\Mapping as ORM;

/**
 * @ORM\Entity(repositoryClass="App\Repository\UserInstanceRepository")
 * @ORM\Table(name="app_user_instance")
 */
class UserInstance
{
    /**
     * @ORM\Id()
     * @ORM\GeneratedValue()
     * @ORM\Column(type="integer")
     */
    private $id;

    /**
     * @ORM\ManyToOne(targetEntity="App\Entity\User")
     * @ORM\JoinColumn(nullable=false)
     */
    private $user;

    /**
     * @var string
     *
     * @ORM\Column(type="string")
     */
    private $contactNumber;

    /**
     * @var string
     *
     * @ORM\Column(type="string", nullable=true)
     */
    private $directContactNumber;

    /**
     * @ORM\ManyToOne(targetEntity="App\Entity\PreferredContact")
     * @ORM\JoinColumn(nullable=false)
     */
    private $preferredContact;

PreferredContactEntity：

<?php

namespace App\Entity;

use Doctrine\ORM\Mapping as ORM;

/**
 * @ORM\Entity(repositoryClass="App\Repository\PreferredContactRepository")
 * @ORM\Table(name="app_user_preferred_contact")
 */
class PreferredContact
{
    /**
     * @var int
     *
     * @ORM\Id
     * @ORM\GeneratedValue
     * @ORM\Column(type="integer")
     */
    private $id;

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

表PreferredContact：

    $form->handleRequest($request);
    $formUserInstance->handleRequest($request);

    if ($form->isSubmitted() && $form->isValid() && $formUserInstance->isValid()) {
        $this->getDoctrine()->getManager()->flush();

        $entityManager = $this->getDoctrine()->getManager();
        $entityManager->persist($userInstance);
        $entityManager->flush();

        $this->addFlash('success', 'Informations mises à jour avec succès !');

        return $this->redirectToRoute('user_editprofil');

您知道此错误来自何处吗？谢谢
