Doctrine2 One to many relation inverse side not saving owning side id - mysql

Question

I have 2 entities: Submission and Vote.
Submission Entity:
/**
* #ORM\OneToMany(targetEntity="AppBundle\Entity\Votes", mappedBy="submission",cascade={"persist", "remove" })
* #ORM\JoinColumn(name="id", referencedColumnName="submission_id")
*/
protected $vote;
/**
* #return mixed
*/
public function getVote()
{
return $this->vote->toArray();
}
/**
* #param Votes $vote
* #return $this
*
*/
public function setVote(Votes $vote)
{
if (!$this->vote->contains($vote)) {
$this->vote->add($vote);
}
return $this;
}
Vote entity:
/**
* #ORM\ManyToOne(targetEntity="AppBundle\Entity\Submission", inversedBy="id")
* #ORM\JoinColumn(name="submission_id", referencedColumnName="id", nullable=true)
*/
protected $submission;
/**
* #return mixed
*/
public function getSubmission()
{
return $this->submission;
}
/**
* #param mixed $submission
*/
public function setSubmission($submission)
{
$this->submission = $submission;
}
Problem is that when i'm setting vote for previously selected submission:
$submission = $em->getRepository('AppBundle:Submission')->findOneById($submissionId);
$vote = new Votes();
$vote->setId($submission->getId());
$vote->setFeedback($judgeComment);
$vote->setScore($judgeScore);
$vote->setSubmission($submissionId);
$submission->setVote($vote);
$em->persist($submission);
$em->flush();
Vote table
submission_id column is always NULL - i'm not sure what i'm doing wrong. I want to store here submission id, for what this vote is.

Answer 1

You don't have to set ids in doctrine but objects, as it is an ORM
$submission = $em->getRepository('AppBundle:Submission')->findOneById($submissionId);
$vote = new Votes();
$vote->setId($submission->getId()); // <--- Are you sure that you need this?
$vote->setFeedback($judgeComment);
$vote->setScore($judgeScore);
// $vote->setSubmission($submissionId); <--- ERROR!
$vote->setSubmission($submission) // <--- Check advice below
$submission->setVote($vote);
$em->persist($submission);
$em->flush();
If I can also leave a suggestion here, modify setVote as follows
public function setVote(Votes $vote)
{
if (!$this->vote->contains($vote)) {
$this->vote->add($vote);
$vote->setSubmission($this);
}
return $this;
}
and you'll never need to set explicitly both sides of association anymore
I'm also noticing that your class name is plural (should be singular into domain) and that vote attribute into submission is singular (should be plural as it's a collection; you have a -to-Many annotation. Even the setter should be an adder as you're not setting but adding a Vote)

Answer 2

Thank you very much Gerry. Thanks to you problem is solved. Here is the answer:
Submission Entity:
/**
* #ORM\OneToMany(targetEntity="AppBundle\Entity\Votes", mappedBy="submission",cascade={"persist", "remove" })
* #ORM\JoinColumn(name="id", referencedColumnName="submission_id")
*/
protected $vote;
/**
* #return mixed
*/
public function getVote()
{
return $this->vote->toArray();
}
/**
* #param Votes $vote
* #return $this
*
*/
public function setVote(Votes $vote)
{
$this->vote[] = $vote;
$vote->setSubmission($this);
return $this;
}
Vote Entity:
/**
* #ORM\ManyToOne(targetEntity="AppBundle\Entity\Submission", inversedBy="vote")
* #ORM\JoinColumn(name="submission_id", referencedColumnName="id",onDelete="cascade", nullable=true)
*/
protected $submission;
/**
* #return mixed
*/
public function getSubmission()
{
return $this->submission;
}
/**
* #param mixed $submission
*/
public function setSubmission($submission)
{
$this->submission = $submission;
}
Now when i'm adding new vote, everything is fine:
$vote = new Votes();
$vote->setFeedback($judgeComment);
$vote->setScore($judgeScore);
$submission->setVote($vote);
$em->persist($submission);
$em->flush();
result
