Question

当我尝试跑步时：

php app/console doctrine:schema:update --dump-sql

我收到此错误：

未捕获的异常＆＃39; Doctrine \ ORM \ Mapping \ MappingException＆＃39;与消息   ＆＃39;没有为实体“OC \ PlatformeBundle \ Entity \ Advert＆＃39;”指定标识符/主键。

  每个实体都必须有一个标识符/主键。＆＃39;

Advert.php：

namespace OC\PlatformBundle\Entity;

use Doctrine\ORM\Mapping as ORM;

/**
 * Advert
 *
 * @ORM\Table(name="advert")
 * @ORM\Entity(repositoryClass="OC\PlatformBundle\Repository\AdvertRepository")

class Advert
{
    /**
     * @var int
     *
    /**
    * @ORM\Column(name="published", type="boolean")
    */
    private $published = true;

    private $id;

    /**

Answer 1

它是因为你没有在id列上指定主键。

就这样修复

/**
 * @var integer
 *
 * @ORM\Column(name="id", type="integer", nullable=false)
 * @ORM\Id
 * @ORM\GeneratedValue(strategy="IDENTITY")
 */
private $id;

：）

为什么我在尝试运行此命令行时出现此错误？
