Symfony Query doctrine entity - php

Question

I have a problem with a query in doctrine i started using Symfony recently for to be continued a old project in Symfony and now i want learn it.
I start to explain from db and i write only the fields that interest me :
user(id,name,surname,phat)
user_reference(id,id_user[FOREIGN KEY id FROM user],id_user_referenced[FOREIGN KEY id FROM user])
This is the query :
$id_user = $user->getId();
$query = $em->createQueryBuilder()
->select('ur','uu')
->from('DtEcBundle:UserReferences', 'ur')
->innerJoin("ur.id_user","uu")
->where("ur.id_user = :id_user")
->setParameter("id_user",$id_user)
->getQuery();
$userpyramid = $query->getResult();
I print in my twig file id_user_referenced but i would print too "name, surname and path" from USER table
For print id_user_referenced in the Entity UserReferences there is this code:
/**
* Set id_user_referenced
*
* #param \Dt\EcBundle\Entity\User $idUserReferenced
* #return UserReferences
*/
public function setIdUserReferenced(\Dt\EcBundle\Entity\User $idUserReferenced = null) {
$this->id_user_referenced = $idUserReferenced;
return $this;
}
/**
* Get id_user_referenced
*
* #return \Dt\EcBundle\Entity\User
*/
public function getIdUserReferenced() {
return $this->id_user_referenced;
}
Transform a number like id to string in Entity User with:
public function __toString(){
return strval($this->id);
}
Now if i add to my query in the select this:
->select('ur','uu.path')
Symfony send me an error:
Key "idUserReferenced" for array with keys "0, path" does not exist in
DtEcBundle:Profilo:digitalpr-profile.html.twig at line 40
Why?? How can i solved it??

Answer 1

The problem is that doctrine hydrates your result in Array Hydration mode, while you expect Object Hydraion.
In the first case you ask for 2 related objects and doctrine can link them. In the second you ask for an object and for a scalar value, and doctrine cannot link them, so it returns them in two separate fields of an result array.
So the result that you have got from $query->getResult() in case of select('ur','uu.path') is not an array of User objects, but an array of 2 fields - $result[0] where you have all found User objects, and $result['path'] for uu.path - because uu.path is scalar value rather than object.
So you need to make select('ur','uu') and address your result as $result->getIdUserReferenced()->getPath().
Or (if you want to save some resources, but I don't think it worth it) make select('ur','uu.path') and then make var_dump of result. And you will see how to address to what you need.

Answer 2

I try in this mode but is not good
$id_user = $user->getId();
$query = $em->createQueryBuilder()
->select('ur','uu')
->from('DtEcBundle:UserReferences', 'ur')
->innerJoin("ur.id_user","uu")
->where("ur.id_user = :id_user")
->setParameter("id_user",$id_user)
->getQuery();
$userpyramid = $query->getResult();
$form = $this->get('form.factory')->createNamedBuilder('form', 'form')
->setMethod('POST')
->setAction($this->generateUrl('profilo_secondlevel'))
->add('save', 'submit', ['label' => 'Prova'])
->getForm();*/
$result->getIdUserReferenced()->getPath();
return $this->render('DtEcBundle:Profilo:index.html.twig', array(
'user' => $user,
'tags' => $tags,
'followers' =>$followers,
'expert' =>$expert,
'user_expert' =>$user_expert,
'well_cat' =>$well_cat,
'user_notification' => $user_notifications,
"udputenti" => $udputenti,
"userpyramid" => $userpyramid,
"result"=> $result
//'form'=>$form->createView()
));`
