是否可以在Symfony2中为“username”重复条目

Question

在我们的Symfony2应用程序中，我们有一个名为sfGuardUser的类，从FOS\UserBundle\Model\User（FOSUserBundle包的一部分）延伸。所以它继承了该User类中的$ username字段，当我尝试插入重复的用户名时会引发错误。我想要做的是检查用户在抛出该错误之前是否确认了他/她的电话号码和电子邮件地址。

例如，当有人使用用户名“Anna”注册但未确认她的电子邮件和电话号码。其他人应该能够使用用户名“Anna”进行注册。我应该如何实现这种行为？

我试图做attribute override没有任何成功。下面的代码：

use FOS\UserBundle\Model\User as BaseUser; 

/** 
* @ORM\Entity(repositoryClass="sfGuard\Bundle\sfGuardBundle\Entity\sfGuardUserRepository") 
* @ORM\Table(name="sf_guard_user") 
* @ORM\AttributeOverrides({ 
*  @ORM\AttributeOverride(name="email", 
*   column=@ORM\Column(
*    name  = "email_address", 
*    type  = "string", 
*    length = 250, 
*    unique = true 
*   ) 
*  ), 
*  @ORM\AttributeOverride(name="username", 
*   column=@ORM\Column(
*    name  = "username", 
*    type  = "string", 
*    length = 250, 
*    unique = false 
*   ) 
*  ), 
*  @ORM\AttributeOverride(name="enabled", 
*   column=@ORM\Column(
*    name  = "is_active", 
*    type  = "boolean", 
*    nullable = true, 
*    options = { 
*     "default" : 1 
*    } 
*   ) 
*  ) 
* }) 
* @ORM\HasLifecycleCallbacks 
*/ 
class sfGuardUser extends BaseUser 
{ 
    /** 
    * @ORM\Id 
    * @ORM\Column(type="integer") 
    * @ORM\GeneratedValue(strategy="AUTO") 
    */ 
    protected $id; 

    /** 
    * @ORM\Column(name="first_name", type="string", length=255, nullable=true) 
    * @Assert\NotBlank() 
    * @Assert\Length(
    *  min = 2, 
    *  minMessage = "Too short." 
    *) 
    */ 
    protected $firstName; 
}
