class Classes {

      /**

     *
     * @ORM\Column(name="class_id", type="integer")

     * @Annotation\Validator({"name":"Regex", "options":{"pattern":"/^[a-zA-Z][a-zA-Z0-9_-]{0,24}$/"}})

     */
    private $className;

实体Maptechclass

/** @ORM\Entity */
class Maptechclass {

    /**
     * @var integer
     *
     * @ORM\Column(name="map_tech_class_id", type="integer")
     * @ORM\Id
     * @ORM\GeneratedValue(strategy="IDENTITY")
     * @Annotation\Exclude()
     */
    protected $mapTechClassID;

    /**
     * @var integer
     *
     * @ORM\Column(name="map_sch_id", type="integer", nullable=true)

     */
    protected $mapSchID;

    /**
     * @var integer
     *
     * @ORM\Column(name="map_tech_id", type="integer", nullable=true)

     */
    protected $mapTechID;

    /**
     * @ORM\OneToMany(targetEntity="SchoolAdmin\Entity\Classes")
     * @ORM\JoinColumn(name="map_class_id", referencedColumnName="classId")
     * */
    protected $mapClassID;
}

将显示以下错误，如何修复它。字段'mapClassID'上的OneToMany映射需要'mappedBy'属性。

Answer 1

查找

@ORM\OneToMany(targetEntity="SchoolAdmin\Entity\Classes")

将其替换为：

@ORM\OneToMany(targetEntity="SchoolAdmin\Entity\Classes", mappedBy="classId")

Doctrine2加入错误
