So I imagine this is correct:
$entity = $this->em->getReference($this->entity, $idUser);
$ctg = $this->em->getReference($this->entityCategory, $value);
$ctg->setUsers($entity);
$this->em->persist($ctg);
$this->em->flush();
but get the error:
Catchable fatal error: Argument 1 passed to
Doctrine\Common\Collections\ArrayCollection::__construct() must be of the
type array, object given, called in
C:\RDM\rede-market-1\Rede-Market-0\vendor\doctrine\orm\lib\Doctrine\ORM\UnitOfWork.php
on line 547 and defined in
C:\RDM\rede-market-1\Rede-Market-0\vendor\doctrine\collections\lib\Doctrine\Common\Collections\ArrayCollection.php
on line *47*
