symfony2 中未识别的新列未捕获的异常'Doctrine\ORM\Query\QueryException

Question

我在我的项目中使用 symfony 2.4 和 postgresql。在我的语言环境中一切正常，但在服务器上却报错

 "PHP message: PHP Fatal error:  Uncaught exception 'Doctrine\ORM\Query\QueryException' with message 'SELECT p.id, p.username, p.email, p.isEmailConfirmed FROM CityDomGameBundle:Player p WHERE p.email = (:email) AND p.username != (:username)' in /var/...

这里发生错误

$duplicatedEmails = $em->createQueryBuilder()
                ->select('p.id, p.username, p.email, p.isEmailConfirmed')
                ->from('CityDomGameBundle:Player', 'p')
                ->where('p.email = (:email)')
                ->andWhere('p.username != (:username)')
                ->setParameter(':email', $email)
                ->setParameter(':username', $username)
                ->getQuery()
                ->getResult();

我在表中添加了新列 isEmailConfirmed，所以 symfony 似乎无法识别它。如果我从select 语句中删除p.isEmailConfirmed，它将起作用。

这里是实体代码

 /**
 * @var boolean $isEmailConfirmed
 *
 * @ORM\Column(name="isemailconfirmed", type="boolean")
 */
private $isEmailConfirmed;

和方法

 /**
 * @return boolean
 */
public function getIsEmailConfirmed()
{
    return $this->isEmailConfirmed;
}

/**
 * @param $isEmailConfirmed
 * @return $this
 */
public function setIsEmailConfirmed($isEmailConfirmed)
{
    $this->isEmailConfirmed = $isEmailConfirmed;

    return $this;
}

我尝试cache:clear，但没有帮助。有什么想法吗？

更新

运行 php app/console dictionary:schema:update --force 后显示错误

 [Doctrine\DBAL\Exception\NotNullConstraintViolationException]                                      
  An exception occurred while executing 'ALTER TABLE player ADD 
  isemailconfirmed BOOLEAN NOT NULL':  
  SQLSTATE[23502]: Not null violation: 7 ERROR:  column 
  "isemailconfirmed" contains null values 

[Doctrine\DBAL\Driver\PDOException]                                                            
 SQLSTATE[23502]: Not null violation: 7 ERROR:  column 
 "isemailconfirmed" contains null values

但此列的默认值为false 这是我添加列时的查询

alter table player add column isEmailConfirmed boolean default false;

先更新当前表：

update player set isemailconfirmed = false where isemailconfirmed is null

或者像这样更改注释：

/**
 * @var boolean $isEmailConfirmed
 *
 * @ORM\Column(name="isemailconfirmed", type="boolean", nullable=true)
 */
private $isEmailConfirmed;
