问题描述

我对doctrine2中的ManyToMany关系有疑问.即使该关系存在,该关系也不会持久.如果我再次检查,则在两个foreach循环中保持不变,则返回正确的对象.

I have a problem with my ManyToMany relation in doctrine2. The relation doesn't persist even though the relation exists. If i check afther the persist in two foreach loops the correct objects are returned.

第一堂课是Document.

The first class is Document.

class Document extends BaseEntity
{
    ....
    /**
     * @ORM\ManyToMany(targetEntity="Job", mappedBy="documents", cascade={"all"})
     * @ORM\JoinTable(name="job_document")
     */
     protected $jobs;
    ....

第二堂课是乔布斯

class Job extends BaseEntity
{
    ....
    /**
     * @ORM\ManyToMany(targetEntity="Document", inversedBy="jobs", cascade={"all"})
     * @ORM\JoinTable(name="job_document")
     */
    protected $documents;
    ....

在我的控制器中,我执行以下操作:

In my controller I do the following:

$job->addDocument($document);
$document->addJob($job);
$em->persist($job);
$em->flush();

添加功能可以正常工作.当我再次遍历对象时,我可以看到它.

The add functions work fine. I can see it when I loop through the objects afther I do this.

推荐答案

在我看来,您仅尝试更新关系的相反方面,而不是关系的拥有方面.

It seems to me that you only try to update the inverse side and not the owning side of the relationship.
