How to make an Where In subquery in symfony - php

Question

I'm trying to do this SQL query with Doctrine QueryBuilder:
SELECT * FROM events WHERE NOT id in (SELECT event_id FROM ues WHERE user_id = $userID)
The UserEventStatus has foreign keys from User and event, as well as an integer for status.
I now want to query all events that dont have an entry in UserEventStatus from an particular User.
My function for this in the EventRepository looks like this:
public function getUnReactedEvents(int $userID){
$expr = $this->getEntityManager()->getExpressionBuilder();
$originalQuery = $this->createQueryBuilder('e');
$subquery= $this->createQueryBuilder('b');
$originalQuery->where(
$expr->not(
$expr->in(
'e.id',
$subquery
->select('ues.user')
->from('App/Entity/UserEventStatus', "ues")
->where(
$expr->eq('ues.user', $userID)
)
)
)
);
return $originalQuery->getQuery()->getResult();
}
But i get an error that says:
Error: Method Doctrine\Common\Collections\ArrayCollection::__toString() must not throw an exception, caught ErrorException: Catchable Fatal Error: Object of class Doctrine\ORM\EntityManager could not be converted to string (500 Internal Server Error)
Can anyone help me or point me to right point in the docs? Cause i failed to find something that describes my problem.
And another thing is, that I don't know if its possible, but it would be nice. Can I somehow make direct Object requests? I mean not with the string App/Entity/UserEventStatus but with something like UserEventStatus::class or something.
Thanks for your help in advance. :)
EDIT: It has to be $originalQuery->getQuery()->getResult() of course.
If its like it was with $subquery instead i recive [Semantical Error] line I0, col 41 near 'App/Entity/UserEventStatus': Error: Class 'App' is not defined. (500 Internal Server Error)
Second EDIT:
$expr = $this->getEntityManager()->getExpressionBuilder();
$queryBuilder = $this->createQueryBuilder('e');
$subquery= $this->createQueryBuilder('b')
->select('ues.user')
->from('UserEventStatus', "ues")
->add('where', $expr->eq('ues.user', $userID));
$originalQueryExpression = $expr->not($expr->in('e.id', $subquery));
$queryBuilder->add('where', $originalQueryExpression);
return $queryBuilder->getQuery()->getResult();
Third EDIT: Thanks to #Dilek I made it work with a JOIN. This is the final Query:
$queryBuilder = $this->createQueryBuilder('e')
->leftJoin('App\Entity\UserEventStatus', 'ues', 'WITH', 'ues.user=:userID')
->setParameter('userID', $userID)
->where($expr->orX($expr->not(
$expr->eq('e.id','ues.event')
),
$expr->not($expr->eq('ues.user', $userID)))
);
return $queryBuilder->getQuery()->getResult();

Answer 1

Building AND WHERE into a Query
public function search($term)
{
return $this->createQueryBuilder('cat')
->andWhere('cat.name = :searchTerm')
->setParameter('searchTerm', $term)
->getQuery()
->execute();
}
simple is: ->where('cat.name = :searchTerm')
UPDATE :
I think you need to use where in
$qb->add('where', $qb->expr()->in('ues.user', $userID));
And WHERE Or WHERE
