Symfony not getting relation data in twig

Question

Symfony get relational data: I have ReservedOffer object and i am getting values like $reservedOffer->getOfferGroup()->getOffer()->getGood() i get like see image.

But

$reservedOffer->getOfferGroup()->getOffer()->getGood()->getName() // Sony

but in twig if i write

reservedOffer.offerGroup.offer.good.name // i get ''

Why? Any idea?

Hi @FrankB reservedOffer is a controller action parameter so get directly reservedOffer object. — Apoorva Shah

In that case Symfony tries to load the reservedOffer object for you. Might be better to pass the id of the object as parameter and then load it yourself. If you dont understand me then ask me for an example — Frank B

So now i am selectindg data of associated tables also and my issue solves. It worked by

public function findReservedOfferWithRelationData(ReservedOffer $reservedOffer)
{
    return $this->createQueryBuilder('reservedOffer')
        ->select('reservedOffer, offerGroup, offer, good')
        ->join('reservedOffer.offerGroup', 'offerGroup')
        ->join('offerGroup.offer', 'offer')
        ->join('offer.good', 'good')
        ->where('reservedOffer.id = :id')
        ->setParameter('id', $reservedOffer->getId())
        ->getQuery()
        ->getOneOrNullResult();
}

Try to set twig's strict_variables to true and you will see the error

# app/config/config.yml
twig:
    debug:            true
    strict_variables: true
