Delete an entity inside another entity Symfony - symfony

Question

I have 2 entities : User And Love. This is a "One-To-Many, Bidirectional".
Here are my entities:
User:
namespace SE\UserBundle\Entity;
/**
* User
*
* #ORM\Table(name="user")
* #ORM\Entity(repositoryClass="SE\UserBundle\Repository\UserRepository")
*/
class User extends BaseUser
{
//...
/**
* One User has Many Loves.
* #ORM\OneToMany(targetEntity="SE\CoreBundle\Entity\Love", mappedBy="user", cascade={"persist"})
*/
private $loves;
//...
public function __construct()
{
//...
$this->loves = new ArrayCollection();
//...
}
//...
/**
* Remove love
*
* #param \SE\CoreBundle\Entity\Love $love
*/
public function removeLove(\SE\CoreBundle\Entity\Love $love)
{
$this->loves->removeElement($love);
//delete love
}
//...
}
Love :
namespace SE\CoreBundle\Entity;
/**
* Love
*
* #ORM\Table(name="love")
* #ORM\Entity(repositoryClass="SE\CoreBundle\Repository\LoveRepository")
*/
class Love
{
//...
/**
* Many Loves have One User.
* #ORM\ManyToOne(targetEntity="SE\UserBundle\Entity\User", inversedBy="loves", cascade={"persist"})
* #ORM\JoinColumn(name="user_id", referencedColumnName="id")
*/
private $user;
//...
/**
* Set user
*
* #param \SE\UserBundle\Entity\User $user
*
* #return Love
*/
public function setUser(\SE\UserBundle\Entity\User $user = null)
{
$this->user = $user;
return $this;
}
//...
}
My question is:
Is there a way, when i execute removeLove() on my User, the corresponding Love entity autodelete in my database without using an entity manager in my controller. I would like my controller to look like that:
class DefaultController extends Controller
{
public function indexAction()
{
//...
$em = $this->getDoctrine()->getManager();
$user->removeLove($love);
$em->persist($user);
$em->flush();
//...
}
}
And the result would be that, $love would not be in getLoves() of the $user and $love would be delete of the database.

Answer 1

You could try: Orphan Removal option
Make sure Entity Love is not associated with another User. So one Entity Love is always associated with only one User
