学说：没有为指定的 identifier/primary 键

Question

所以我已经设置好了所有内容，但我仍然得到：

No identifier/primary key specified for Entity "Bisna\Application\Entity\Company". Every Entity must have an identifier/primary key.

实体：

<?php
namespace Bisna\Application\Entity;
use Doctrine\ORM\Mapping as ORM;
/**

 * @ORM\Table(name="companies")

    /* .... */
}

我还没有制作表格，但我仍然不明白为什么我会收到这个错误，因为我什么都有。有什么想法吗？

Answer 1

可能是因为您在 $id 属性的 @ORM\Column 注释之前错过了 @？

您应该考虑使用 Yaml 原则映射。这是将实体与数据库列定义分开的好方法。此外，您的 IDE 应该验证 Yaml 内容，而它可能不会将 PHP 评论验证为 PHP 代码。
