onDelete: 'SET NULL' not working in Symfony/Doctrine with Sqlite - php

Question

I'm working on a Symfony 6 project and I'm using sqlite as db.
I have a ManyToOne relation between two entities: Neighborhood and PropertyForSale.
When I delete a Neighborhood I want the $Neighborhood field of PropertyForSale to be set to null so I added:
#[ORM\JoinColumn(onDelete: 'SET NULL')] to the property:
#[ORM\ManyToOne(inversedBy: 'propertiesForSale')]
#[ORM\JoinColumn(onDelete: 'SET NULL')]
private ?Neighborhood $neighborhood = null;
Everything seems to work properly if I change the database to MySql but with Sqlite this attribute seems to be ignored. I know has something to do with the default foreign key behavior in sqlite and
PRAGMA foreign_keys = ON; should be executed but I can´t find I way to make it work with Symfony and Doctrine; Any ideas?
I share a bigger portion of my code:
// PropertyForSale.php
#[ORM\Entity(repositoryClass: PropertyForSaleRepository::class)]
class PropertyForSale
{
// ...
#[ORM\ManyToOne(inversedBy: 'propertiesForSale')]
#[ORM\JoinColumn(onDelete: 'SET NULL')]
private ?Neighborhood $neighborhood = null;
// ...
public function getNeighborhood(): ?Neighborhood
{
return $this->neighborhood;
}
public function setNeighborhood(?Neighborhood $neighborhood): self
{
$this->neighborhood = $neighborhood;
return $this;
}
}
// Neighborhood.php
#[ORM\Entity(repositoryClass: NeighborhoodRepository::class)]
class Neighborhood
{
// ...
#[ORM\OneToMany(mappedBy: 'neighborhood', targetEntity: PropertyForSale::class)]
private Collection $propertiesForSale;
// ...
public function getPropertiesForSale(): Collection
{
return $this->propertiesForSale;
}
public function addPropertiesForSale(PropertyForSale $propertiesForSale): self
{
if (!$this->propertiesForSale->contains($propertiesForSale)) {
$this->propertiesForSale->add($propertiesForSale);
$propertiesForSale->setNeighborhood($this);
}
return $this;
}
public function removePropertiesForSale(PropertyForSale $propertiesForSale): self
{
if ($this->propertiesForSale->removeElement($propertiesForSale)) {
// set the owning side to null (unless already changed)
if ($propertiesForSale->getNeighborhood() === $this) {
$propertiesForSale->setNeighborhood(null);
}
}
return $this;
}
}
The only workaround I found was to add an event listener on the entity preRemove event and manually set to null the relation:
// NeighborhoodListener
namespace App\EventListener;
use Doctrine\ORM\EntityManagerInterface;
class NeighborhoodListener
{
public function __construct(private EntityManagerInterface $entityManager) {}
public function preRemove($args) {
$properties = $args->getObject()->getPropertiesForSale();
foreach ($properties as $property) {
$property->setNeighborhood(null);
$this->entityManager->persist($property);
}
$this->entityManager->flush();
}
}
