Symfony 4实体/ DTO用户正在积极验证

Question

我有一个密码提醒表单，其中一个字段=电子邮件。下面的代码。如果用户处于活动状态，如何添加其他验证？最佳做法是什么？ EntityExist约束是我自己的代码。

namespace App\DTO\Admin\System;
use Symfony\Component\Validator\Constraints as Assert;
use App\Validator\Constraints as AppAssert;
class PasswordRemindData {
  /**
     * @Assert\NotBlank(message="validation.field.required")
    * @Assert\Email(message="validation.email.invalid")
    * @AppAssert\EntityExists(entityClass="App\Entity\Admin", field="email", message="validation.user.not_exists")
   * @var string|null
   */
  private $email;
 public function __construct(?string $email = null) {
      $this->email = $email;
 }
/**
 * 
 * @return string|null
 */
 public function getEmail() {
    return $this->email;
 }
 /**
 * 
 * @param string|null $email
 * @return PasswordRemindData
 */
public function setEmail($email) {
    $this->email = $email;
    return $this;
}
/**
 * 
 * @param string $email
 * @return PasswordRemindData
 */
  public static function create(string $email) {
      return new self($email);
  }
}
