How to execute two repository functions in one Action - symfony

Question

I have a problem. I want to execute this
$events1 = $em->getRepository('AfishaBundle:Event')->getEvents($this->getCurrentRegion(),'2012-11-12');
//$event_repo->clear();`
$events2 = $em->getRepository('AfishaBundle:Event')->getEvents($this->getCurrentRegion(),'2012-11-13');
foreach($events2 as $event){
die(var_dump($event->getSeanses()->toArray()));
}
But result return with first date = "2012-11-12"
when I not use $event_repo->clear();
That's ok but I have a problem with Twig rendering.
Can I execute this without clear() method ? If I can't, please comment.
For sake of completeness, this is getEvents() code:
public function getEvents($region, $date){
$qb = $this->_em->createQueryBuilder();
$qb
->select('e,s')
->from('AfishaBundle:Event', 'e')
->leftJoin('e.seanses', 's')
->andWhere('s.date = :date')
->andWhere('s.region = :region')
->setParameter('region', $region)
->setParameter('date',$date)
;
return $qb->getQuery()->getResult();
}
This is the relation between Event and EventSeans:
/**
* #ORM\OneToMany(
* targetEntity="EventSeans",
* cascade={"persist", "remove", "merge"},
* mappedBy="event"
* )
* #ORM\OrderBy({"time"= "ASC"})
*/
protected $seanses;
Finally, this is date field in EventSeans entity
/**
* #ORM\Column(name="date", type="date")
*/
protected $date;

Please, consider that it's really hard to understand what you are asking for! I understood that when you pass two different dates to the getEvents() function you always get the same result.
It seems that the code you currently posted is ok, but you are going to do is not to select the Event entities with the getEvents() function.
If you ready the query from you QueryBuilder, you are selecting the EventSeans entities such that the $region and $date are the one provided by you! But you are nor selecting the Event entities nor involving the relationship between Event and EventSeans entities.
Maybe with more details and a better explanation of your problem one could helps.
EDIT
I think you should not select both Event and EventSeanses, since you can get all the EventSeanses objects from the Event entity once you retrieve the Event from repo. But I suggest to select all the EventSeanses such that the criteria are satisfied, and then to get the associated Event object directly from the EventSeanses object. Clean and easy.
public function getEventSeanses($region, $date){
$qb = $this->_em->createQueryBuilder();
$qb
->select('s')
->from('AfishaBundle:EventSeanses', 's')
->andWhere("s.date = ':date'")
->andWhere('s.region = :region')
->setParameter('region', $region)
->setParameter('date',$date)
;
return $qb->getQuery()->getResult();
}
Notice that in SQL you should put strings (like a date) like follows 'date' and not simply date.
Then, in your controller you should do as follows:
$events = array();
$region=...
$date=....//year-month-day
$eventseansesList = $em->getRepository('AfishaBundle:EventSeanses')->getEventSeanses($region,$date);
foreach($eventseansesList as $es){
$events[] $es->getEvent(); // this function retrieve the Event associated to the EventSeanses
}
PS: You order $seanses by "time" in Event and not by "date", That's strange!
