Symfony 运行时通知：访问静态属性代理\\uuu CG\uuuu\SimpleDiabundle\Entity\Media:：$LazyProperties默认为非静态

我创建了一个名为SimpleMedia的自定义包。当我尝试加载加载公司的页面时，它会给我运行时通知

运行时通知：访问静态属性代理\uuuu CG\uuu\simpleDiabundle\Entity\Media:：$LazyProperties默认为非静态

我知道这和我一对一的关系有关

(logoFile(Company Entity) -> id (Media Entity).

有人有什么想法吗？我正在使用Symfony 2.7

我认为你对这段关系的定义是错误的。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company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“渴望”为我解决了这个问题

  private $logoFile;

在MAMPNo上不在本地运行在MAMPI上不在本地运行我想在这种情况下它应该是@ORM\JoinColumn而不是@ORM\JoinColumns。我想你是对的，它不是ArrayCollection（）。我做了这些更改，但仍然存在相同的问题。我认为在这种情况下，应该是@ORM\JoinColumn而不是@ORM\JoinColumns。我想你是对的，它不是ArrayCollection（）。我做了这些更改，但仍然存在相同的问题。
