I have document with ReferenceOne:
/** @MongoDB\Document */
class Petition
{
// ...
/** @MongoDB\ReferenceOne(targetDocument="AcmeBundle\Document\Result",
cascade={"persist"}) */
protected $result;
public function setResult($result)
{
$this->result = $result;
return $this;
}
// ...
}
And documents referenced:
/** @MongoDB\Document */
class Result
{
// ...
/** @MongoDB\Id(strategy="NONE") */
protected $id;
// ...
}
Somewhere in my code:
$r = $this->mongo->getManager()->find('AcmeBundle:Result', 0);
$dm = $this->mongo->getManager();
$pet = new \AcmeBundle\Document\Petition($res->data);
$pet->setResult($r);
$dm->persist($pet);
$dm->flush();
Mongo database and collection has a document 'Result' with id = 0 (
{'_id':0, 'title':''})
I get RuntimeException, when try persist 'Petition' document:
[RuntimeException]
Cannot create a DBRef for class AcmeBundle\Document\Result without an
identifier. Have you forgotten to persist/merge the document first?
And StackTrace:

Probably should checking to change the condition to *isset*()?

Or I misunderstood concept of Mongo?
Thanks for doctrine :)
