原则-“缺少主键的值” [英] Doctrine - "Missing value for primary key"

问题描述

我对无效的映射有疑问。我不断收到错误消息：

I have a problem with an invalid mapping. I keep getting an error with message:

Namespace\XXX\Entity\Subject上主键课程的缺失值

Missing value for primary key course on "Namespace\XXX\Entity\Subject"

doctrine：schema：validate命令返回以下内容：

The doctrine:schema:validate command returns the following:

[映射]失败-实体类名称空间\XXX\实体\主题映射无效：
*关联日程表的联接列必须与ALL标识符匹配目标实体名称空间\XXX\实体\主题的列，但是缺少 id，路线，班级，日期，时间段。

[Mapping] FAIL - The entity-class 'Namespace\XXX\Entity\Subject' mapping is invalid: * The join columns of the association 'schedule' have to match to ALL identifier columns of the target entity 'Namespace\XXX\Entity\Subject', however 'id, course, class, day, timeslot' are missing.

这是我的映射：

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

/**
 * @var string
 *
 * @ORM\Column(name="message", type="string", length=255)
 */
private $message;

/**
 * @ORM\ManyToOne(targetEntity="Oggi\ScheduleBundle\Entity\Schedule", inversedBy="subjects")
 * @ORM\JoinColumn(name="schedule", referencedColumnName="id")
 */
private $schedule;

/**
 * @var \DateTime
 *
 * @ORM\Column(name="date", type="date")
 */
private $date;

/**
 * @var \DateTime
 *
 * @ORM\Column(name="created", type="datetime")
 */
private $created;

计划实体

/ **
* @var整数
*
* @ ORM\Column（name = id，type = integer）
* @ ORM\Id
* /
private $ id;

Schedule Entity

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

/**
 * @var string
 *
 * @ORM\Id
 * @ORM\OneToOne(targetEntity="Oggi\KlasBundle\Entity\Course")
 * @ORM\JoinColumn(name="course", referencedColumnName="id")
 */
private $course;

/**
 * @var string
 *
 * @ORM\Id
 * @ORM\ManyToOne(targetEntity="Oggi\KlasBundle\Entity\Klas", inversedBy="schedules")
 * @ORM\JoinColumn(name="class", referencedColumnName="id")
 */
private $klas;

/**
 * @var string
 *
 * @ORM\Id
 * @ORM\OneToOne(targetEntity="Day")
 * @ORM\JoinColumn(name="day", referencedColumnName="id")
 */
private $day;

/**
 * @var string
 *
 * @ORM\Id
 * @ORM\OneToOne(targetEntity="Timeslot")
 * @ORM\JoinColumn(name="timeslot", referencedColumnName="id")
 */
private $timeslot;

/**
 * @ORM\OneToMany(targetEntity="Oggi\CalendarBundle\Entity\Subject", mappedBy="schedule")
 */
private $subjects;

我想Symfony告诉我要做的是将所有主键都包含在我的主体中。有没有一种方法可以只在该实体中包含计划的ID。我想到了：

I suppose that what Symfony is telling me to do is include all primary keys in my subject-entity. Is there a way to only include the ID of the schedule in this entity. I had this in mind:

预先感谢！

推荐答案

出现此错误的原因是因为您的时间表实体中的所有列都标记为 Id 。

The reason you get this error is because all columns in your Schedule entity are marked as an Id.

只需从除 $ id 之外的所有列中删除 @ ORM\Id -这样就可以解决这种情况

Just remove @ORM\Id from all columns but $id - this should fix the case
