Doctrine 2 removes parent row - php

Question

I have defined two database entities
Project:
use Doctrine\ORM\Mapping as ORM;
use \Kdyby\Doctrine\Entities\MagicAccessors;
/**
* #ORM\Entity
*/
class Project extends \Kdyby\Doctrine\Entities\BaseEntity
{
/**
* #ORM\Id
* #ORM\Column(type="integer")
* #ORM\GeneratedValue
*/
public $id;
/**
* #ORM\Column(type="string")
*/
public $title;
/**
* #ORM\Column(type="text")
* #var string
*/
public $description;
/**
* #ORM\Column(type="datetime", nullable=true)
* #var DateTime
*/
public $created;
/**
* #ORM\Column(type="boolean")
* #var string
*/
public $public;
/**
* #ORM\Column(type="blob")
* #var string
*/
public $thumbnail;
public function __construct()
{
$this->created = new \DateTime();
$this->public = 0;
}
}
and Personage:
use Doctrine\ORM\Mapping as ORM;
use \Kdyby\Doctrine\Entities\MagicAccessors;
/**
* #ORM\Entity
*/
class Personage extends \Kdyby\Doctrine\Entities\BaseEntity
{
/**
* #ORM\Id
* #ORM\Column(type="integer")
* #ORM\GeneratedValue
*/
public $id;
/**
* #ORM\Column(type="string")
*/
public $name;
/**
* #ORM\Column(type="text", nullable=true)
* #var string
*/
public $shortDescription;
/**
* #ORM\Column(type="text", nullable=true)
* #var string
*/
public $playerDescription;
/**
* #ORM\Column(type="datetime")
* #var DateTime
*/
public $created;
/**
* #ORM\Column(type="integer")
* #var string
*/
public $creator;
/**
* #ORM\Column(type="boolean", options={"default" = false})
* #var boolean
*/
public $inGraph;
/**
* #ORM\Column(type="boolean", nullable=false, options={"default" = 0})
* #var boolean
*/
public $deleted;
/**
* #ORM\ManyToOne(targetEntity="Project", cascade={"persist", "remove"})
* #ORM\JoinColumn(name="project", referencedColumnName="id", onDelete="CASCADE")
* #var string
*/
public $project_id;
public function __construct()
{
$this->deleted = 0;
$this->inGraph = 0;
}
}
Every Personage entity belongs to some project. But whenever I try to remove Personage either this way:
public function removeChar($id)
{
$a = $this->EntityManager->find('App\Personage', $id);
if($a->deleted)
{
$this->EntityManager->remove($a);
$this->EntityManager->flush();
}
}
or using dql. It removes the whole project row as well. What i want is whenever project is removed it removes all characters corresponding but NOT other way around.
I tried to remove
cascade={"persist", "remove"}
part from Project entity declaration (and updating database via console) but it said everything was in sync and did nothing. So I removed whole database and build it without cascade={"persist", "remove"}, but the problem was not solved.

Answer 1

remove onDelete="CASCADE" from
#ORM\JoinColumn(name="project", referencedColumnName="id", onDelete="CASCADE")
and add
#ORM\OneToMany(targetEntity="Personage", mappedBy="project_id",cascade={"remove"})
private $personages;
in the project entity.
