I have two Documents, Question and Image : The Question references one Image.
/**
*@MongoDB\ReferenceOne(targetDocument="Image")
*/
protected $image ;
When I add the Image field in the back-end using sonata admin bundle :
->add('image', 'sonata_type_admin', array('by_reference' => false))
The uploading Button appears but when I try to persist the question I got this exception :
Cannot create a DBRef without an identifier. UnitOfWork::getDocumentIdentifier() did not return an identifier for class ATS\\QuizzBundle\\Document\\Image Any one knows the origin of this error please ? thank you
I think it is the same problem which has been patched i think, but you should look at it, if it is already pushed then update mongodb if it helps.
