Doctrine2 ManyToMany-relation doesn't save

Question

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.

The first class is Document.

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

The second class is Job

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

In my controller I do the following:

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

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

Have you managed to get this working? – pagliuca Feb 26 '13 at 23:37 — pagliuca, Feb 26 '13 at 23:37

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

As pointed out in the doctrine documentation:

Changes made only to the inverse side of an association are ignored. Make sure to update both sides of a bidirectional association (or at least the owning side, from Doctrine’s point of view)

Some lines above the excerpt I have: $em->persist($document); – Pino Oct 08 '12 at 12:09
@Pino But you have to persist the document after adding the Job. – k0pernikus Oct 08 '12 at 12:13
I don't think you have to, but I tried it. Same result. The relation isn't saved, both entities are. – Pino Oct 08 '12 at 12:40
