Symfony2: spl_object_hash() si aspetta parametro 1 per essere oggetto, stringa di dato in Dottrina

Question

Sto cercando di popolare il database con l'utente oggetto e persona eseguendo

persistono e filo.

Prima di tutto, sto creando l'oggetto Person e persistono e sciacquare:

$person->setFirstname($enquiry->getFirstname()); 
$person->setLastname($enquiry->getLastname()); 
$person->setLastname($enquiry->getLastname()); 
$person->setSex($enquiry->getSex()); 
$person->setEmail($enquiry->getEmail()); 
$person->setAddress1($enquiry->getAddress1()); 
$person->setAddress2($enquiry->getAddress2()); 
$person->setCity($enquiry->getCity()); 
$person->setZipcode($enquiry->getZipcode()); 
$country = $em->getRepository('SciForumVersion2Bundle:Country')->findOneById($enquiry->getCountry()); 
$person->setCountry($country); 

$em->persist($person); 
$em->flush(); 

E poi il mio oggetto User:

$user->setEmail($enquiry->getEmail()); 
$user->setPassword($enquiry->getPassword()); 
$user->setPersonId($person->getId()); 
$user->setDegree($enquiry->getDegree()); 
$user->setSex($enquiry->getSex()); 
$user->setOrganization($enquiry->getOrganization()); 
$user->setTelephone($enquiry->getTelephone()); 
$user->setFax($enquiry->getFax()); 
$user->setWorkplace($enquiry->getWorkplace()); 
$user->setJobtype($enquiry->getJobtype()); 
$user->setResearchField($enquiry->getResearchField()); 
$user->setManageConference(0); 
$user->setIp($IP); 
$user->setStatus(0); 
$user->setDateRegistered(time()); 

$em->persist($user); 
$em->flush(); 

Ma quando si cerca di svuotare() il persistere di l'oggetto utente, sto ottenendo l'errore:

Warning: spl_object_hash() expects parameter 1 to be object, string given in /home/milos/workspace/conference2.0/vendor/doctrine/lib/Doctrine/ORM/UnitOfWork.php line 1095 

Ed ecco il LOG entier:

Answer 1

ho finalmente trovato il problema:

Quando si crea l'oggetto utente, invece di impostare quei campi

$user->setDegree(); 
$user->setWorkplace(); 
$user->setJobtype(); 
$user->setResearchField(); 

come oggetti (a causa del rapporto OneToMany), mi gived qui solo una stringa, dal modulo.

Così, per quei campi, il codice sarebbe:

$degree  = $em->getRepository('SciForumVersion2Bundle:Degree')->findOneById($enquiry->getDegree()); 
$workplace = $em->getRepository('SciForumVersion2Bundle:Workplace')->findOneById($enquiry->getWorkplace()); 
$job_type = $em->getRepository('SciForumVersion2Bundle:JobType')->findOneById($enquiry->getJobtype()); 
$research_field = $em->getRepository('SciForumVersion2Bundle:ResearchField')->findOneById($enquiry->getResearchField()); 

E poi:

$user->setPerson($person); 
$user->setWorkplace($workplace);  
$user->setJobtype($job_type); 
$user->setResearchField($research_field); 

Quindi: Fare attenzione quando si stanno ottenendo questo tipo di avvertimenti, probabilmente deve controllare se stai popolando il tuo oggetto nel modo giusto.
