我创建了一个名为 SimpleMedia 的自定义捆绑包。当我尝试加载加载公司的页面时，它会给我运行时通知
运行时注意：访问静态属性Proxies__CG __ \ SimpleMediaBundle \ Entity \ Media :: $ lazyPropertiesDefaults为非静态。
我知道这与我的一对一关系有关
(logoFile(Company Entity) -> id (Media Entity).
有人有什么想法吗？我正在使用 Symfony 2.7
控制器

$response = $this->createApiResponse($company, 200);
return $response;
}

$company = $this->getDoctrine()

throw $this->createNotFoundException(sprintf(
'No company found with id "%d"',

答案 0 :(得分：0)
我认为你已经把关系定义错了。我认为应该是：
/**
*
* @ORM\OneToOne(targetEntity="SimpleMediaBundle\Entity\Media", cascade={"persist", "remove"}, orphanRemoval=true)
* @ORM\JoinColumn(name="logo_file", referencedColumnName="id", nullable=true)
*/
protected $logoFile;
另一方面，在公司构造函数中，您不需要初始化$ logoFile变量，因为它不是数组，只是一个值。

将获取模式更改为 EAGER 为我解决了这个问题。
/**
* @var Media
*
* @ORM\OneToOne(targetEntity="SimpleMediaBundle\Entity\Media", cascade={"persist", "remove"}, orphanRemoval=true, fetch="EAGER")
* @ORM\JoinColumn(name="logo_file", referencedColumnName="id", nullable=true)
*/
private $logoFile;
