so this is my prePersist on EventListener
public function prePersist(LifecycleEventArgs $args)
{
//the first entity will have the PMP, so we catch it and continue to skip this if after this
if ($this->pmp == null) {
$this->pmp = $args->getEntity()->getPmp();
}
$taxonomicClass = $args->getEntity();
if($taxonomicClass instanceof TaxonomicClass){
if(is_null($taxonomicClass->getId())){
//here it says that i have created a new entity, need to persist it via cascade={"persist"}
$taxonomicClass->setPmp($this->pmp);
}
}
}
that's fine, i had added the annotation on it:
/**
* @ORM\ManyToOne(targetEntity="AppBundle\Entity\Pmp", cascade={"persist"})
* @ORM\JoinColumn(name="pmp_id", referencedColumnName="id", nullable=false)
**/
private $pmp;
and it saves everything from my hierarchy, even a new PMP, an object that already exist in the database!
what i want is that everything that im saving from my hierarchy needs to be related to the PMP that i passed, but when i set $taxonomicClass->setPmp($this->pmp);
doctrine thinks that i created a new instance of PMP, since im not, i just want to this guy have an associaton with the PMP.
i tried put merge
on the cascade option, but it only works with persist
, how to make doctrine dont create a new instance, and instead use the one that i passed?
