I've a ManyToMany relation in Listing entity:
/**
* @ORM\Entity(repositoryClass="AppBundle\Repository\ListingRepository")
* @ORM\Table(name="listings")
*/
class Listing extends MainEntity
{
/**
* @ORM\Id
* @ORM\Column(type="uuid")
*/
private $id;
/**
* @ORM\ManyToMany(targetEntity="AppBundle\Entity\AttributeDescription", inversedBy="listings", cascade={"persist", "remove"})
* @JoinTable(name="listing_attriubute_descriptions",
* joinColumns={@JoinColumn(name="listing_id", referencedColumnName="id")},
* inverseJoinColumns={@JoinColumn(name="attribute_description_id", referencedColumnName="id")}
* )
*/
public $attributeDescriptions;
public function __construct()
{
$this->id = Uuid::uuid4();
$this->attributeDescriptions = new ArrayCollection();
}
public function removeAttributeDescription(AttributeDescription $attributeDescription)
{
if(!$this->attributeDescriptions->contains($attributeDescription))
{
return;
}
$this->attributeDescriptions->remove($attributeDescription);
return $this;
}
}
Somewhere in the ListingService I'm trying to remove AttributeDescription from the Listing entity like this:
$listing->removeAttributeDescription($toRemoveAttributeDescription);
But got an error: Warning: Illegal offset type in isset or empty
Using xdebug I've landed to remove() method in ArrayCollection:
public function remove($key)
{
if ( ! isset($this->elements[$key]) && ! array_key_exists($key, $this->elements)) {
return null;
}
$removed = $this->elements[$key];
unset($this->elements[$key]);
return $removed;
}
And found out that the problem comes from isset($this->elements[$key]). Here is the screenshot from xdebug:
As you can see the $key contains an AttributeDescription, and the $this->elements is an array of AttributeDescriptions.
I really don't get whether I'm doing something wrong or is this a doctrine bug?
I'm using: Symfony 3.3.13 with php 7.1.1
Doctrine:
"doctrine/doctrine-bundle": "^1.6",
"doctrine/doctrine-cache-bundle": "^1.2",
"doctrine/doctrine-migrations-bundle": "^1.2",
