Question

I have entity Patients with a field

/**
 *
 * @ORM\OneToOne(targetEntity="Surgery\LoginBundle\Entity\User" , mappedBy="patient")
 * @ORM\JoinColumn(name="user_id", referencedColumnName="id")
 */
 protected $user;

I want to get foreign key from Patiens ,so I created that query

$query = $em->createQuery('SELECT p.user_id FROM SurgeryPatientBundle:Patients p WHERE p.user =5 ');

I get this error

[Semantical Error] line 0, col 9 near 'user_id FROM': Error: Class Surgery\PatientBundle\Entity\Patients has no field or association named user_id '

My question it’s can I get to that field without create JOIN ?

Answer 1

Try this:

$query = $em->createQuery('SELECT u.id FROM SurgeryPatientBundle:Patients p JOIN p.user u WHERE p.user =5')

or

$patient = $em->getRepository('SurgeryPatientBundle:Patients')->findOneBy(array('user' => 5));
$user = $patient->getUser()->getId();
