Symfony one to many dql query - php

Question

I am creating symfony web app and have problem with making appropiate dql query for inbox.
This is code of entity causing problems:
class Message
{
/**
* #ORM\Column(type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
*/
protected $id;
/**
* #OneToOne(targetEntity="User")
* #JoinColumn(name="fromUser", referencedColumnName="id")
*/
protected $fromUser;
/**
* #ORM\Column(type="text")
*/
protected $fromEmail;
/**
* #return mixed
*/
/**
* #OneToOne(targetEntity="User")
* #JoinColumn(name="toUser", referencedColumnName="id")
*/
protected $toUser;
/**
* #ORM\Column(type="text",length=255)
*/
protected $subject;
/**
* #ORM\Column(type="datetimetz")
*/
protected $date;
/**
* #ORM\Column(type="text")
*/
protected $toEmail;
/**
* #ORM\Column(type="text")
*/
protected $content;
/**
* #ORM\Column(type="boolean")
*/
protected $sent;
/**
* #ORM\Column(type="boolean")
*/
protected $spammed;
/**
* #ManyToMany(targetEntity="View")
* #JoinTable(name="messages_views",
* joinColumns={#JoinColumn(name="message_id", referencedColumnName="id")},
* inverseJoinColumns={#JoinColumn(name="view_id", referencedColumnName="id", unique=true)}
* )
*/
protected $view;
class View extends CollectionType
{
public function __construct($user)
{
$this->user = $user;
$this->trashed = false;
$this->deleted = false;
$this->seen = false;
}
/**
* #ORM\Column(type="boolean")
*/
protected $trashed;
/**
* #ORM\Column(type="boolean")
*/
protected $deleted;
/**
* #ORM\Column(type="boolean")
*/
protected $seen;
/**
* #ManyToOne(targetEntity="User")
* #JoinColumn(name="user_id", referencedColumnName="id")
*/
protected $user;
}
$view is class ArrayCollection() and one to many relationship.
And i want to choose field "where $toUser = :me" and which contains $view where $view->user = :me and $view->trashed = false" (in case if there are two $view's (not possible/expected ) choose first found)
Thanks in advance for your time.
Edit:
at the moment i have something like this
$get = $this->getEntityManager()
->createQuery('
SELECT m
FROM MonoAdminBundle:Message m
WHERE m.userTo = :me AND m.sent = true
AND
ORDER BY m.date DESC
')
->setParameter('me', $me->getId())->getArrayResult();
$ret = new \Doctrine\Common\Collections\ArrayCollection();
foreach ($get as $message) {
if ($message->getSpammed() === false) {
foreach ($message->getView() as $view) {
if ($view->getUser() == $me) {
if ($view->getTrashed() === false) {
$ret->add($message);
}
}
}
}
}
But it is not good idea as i want to use paginator.

Try to use a queryBuilder.
$qb = $entityManager->getRepository(Message::class)->createQueryBuilder('m');
$qb->addWhere('m.toUser = :me')
->innerJoin('m.view', v)
->addWhere('v.user = :me')
->addWhere('v.trashed = :isTrashed')
->setParameter('me', $user)
->setParameter('isTrashed', false);
To get DQL:
$qb->getQuery()->getDQL();
Then get results:
$qb->getQuery()->getResults();
