从 FOSUserBundle 扩展的用户导致 Easyadmin 列表偏移处的 unserialize() 错误

Question

我使用 1.16.10 版本的 EasyAdminBundle。我创建了用户实体，从 FOSUser 的模型中扩展了它（如文档中所示）并将其添加到 easyadmin 配置文件中。结果我得到了以下错误：

An exception has been thrown during the rendering of a template ("Notice: unserialize(): Error at offset 0 of 34 bytes").

堆栈跟踪的完整描述：

CRITICAL - Uncaught PHP Exception Twig_Error_Runtime: "An exception has been thrown during the rendering of a template ("Notice: unserialize(): Error at offset 0 of 34 bytes")." at \vendor\javiereguiluz\easyadmin-bundle\Resources\views\default\list.html.twig line 132

所以，我的实体代码：

namespace BackofficeBundle\Entity;

use Doctrine\ORM\Mapping as ORM;
use FOS\UserBundle\Model\User as BaseUser;
use Gedmo\Mapping\Annotation as Gedmo;

/**
 * AclUser
 *
 * @ORM\Entity(repositoryClass="BackofficeBundle\Repository\AclUserRepository")
 * @ORM\Table(name="Acl_User")
 */
class AclUser extends BaseUser
{
/**
 * @ORM\Id
 * @ORM\Column(type="integer")
 * @ORM\GeneratedValue(strategy="AUTO")
 */
protected $id;

/**
 * @var string
 *
 * @ORM\Column(name="ip_address", type="string", length=255, nullable=true)
 */
private $ipAddress;

/**
 * @var boolean
 *
 * @ORM\Column(name="locked", type="boolean")
 */
private $locked = false;
/**
  * @ORM\Column(name="expired", type="boolean")
  */
private $expired = false;

/**
 * @ORM\Column(name="expires_at", type="datetime", nullable=true)
 */
private $expiresAt;

/**
 * @ORM\Column(name="credentials_expired", type="boolean", nullable=true)
 */
private $credentialsExpired;

/**
 * @ORM\Column(name="credentials_expire_at", type="datetime", nullable=true)
 */
private $credentialsExpireAt;

/**
 * @var \DateTime
 *
 * @ORM\Column(name="created_at", type="datetime", nullable=false)
 */
private $createdAt;

/**
 * @var \DateTime
 *
 * @Gedmo\Timestampable(on="update")
 *
 * @ORM\Column(name="updated_at", type="datetime", nullable=false)
 */
private $updatedAt;

public function __construct()
{
    parent::__construct();
    $this->createdAt = new \DateTime('now');
}
 /** generated getters and setters **/
}`

我的 user.yml 文件，导入到 config.yml:

easy_admin:
    entities:
        User:
            class: BackofficeBundle\Entity\AclUser
            list:
                fields:
                    - id
                    - username
                    - email
                    - enabled
                    - lastLogin
                    - { property: roles, type: json_array, template: '@BackofficeBundle/Resources/views/fields/role.html.twig' }

            form:
                fields:
                    - username
                    - email
                    - enabled
                    - lastLogin
                    - { property: 'plainPassword', type: 'text', type_options: { required: false } }
                    - { property: 'roles', type: 'choice', type_options: { multiple: true, choices: { 'ROLE_APP_SUPER_ADMIN' : 'ROLE_APP_ADMIN', 'ROLE_APP_ADMIN' : 'ROLE_APP_USER', 'ROLE_APP_USER' : 'ROLE_USER' } } }`

我做错了什么？是什么导致了这个错误？我该如何解决？

Answer 1

FOS UserBundle 的基础 User-model 包含序列化和反序列化，将模型的属性输出为数组，然后对其调用序列化并再次从该数组反序列化和设置自身。

我的假设是，您要么重命名了其中一些属性，要么尝试加载一个包含反序列化无法处理的数据的模型，例如因为数据在某个时候被截断了或者类似的奇怪的事情。您可能想要清除旧会话，因为据我所知 serialize/unserialize 仅用于在会话中存储数据，或者您可能希望通过查看它试图反序列化的序列化数据来开始调试。
