Remove OneToOne unidirectionnal relation - symfony

Question

I have an entity called Upload and another one called Shop
The Shop can have only one Upload
class Shop
{
/**
* #var integer $id
*
* #ORM\Column(name="id", type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* #var Upload
*
* #ORM\OneToOne(targetEntity="Vendor\SystemBundle\Entity\Upload",cascade={"all"})
*/
private $myfile;
}
class Upload
{
/**
* #var integer $id
*
* #ORM\Column(name="id", type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* #var string $name
*
* #ORM\Column(name="name", type="string")
*/
private $name;
/**
* #var string $path
*
* #ORM\Column(name="path", type="string")
*/
private $path;
/**
* #var string $uniqId
*
* #ORM\Column(name="uniqId", type="string", nullable=true)
*/
private $uniqId;
/**
* #var integer $size
*
* #ORM\Column(name="size", type="integer", nullable=true)
*/
private $size;
/**
* #var string $extension
*
* #ORM\Column(name="extension", type="string", nullable=true)
*/
private $extension;
}
! Because my class Shop is generated automatically, i can't specify the relation into my class Upload
Is there a way to remove the relation and delete the corresponding item.
For now, if i want to remove my entity Upload, it says i have a Foreign Key contraint (which is normal), so I am trying to remove the relation directly from Shop, but I don't know how to do

Answer 1

You generated it using the php app/console doctrine:generate:entity command?
If you want to remove the relation remove the part
/**
* #var Upload
*
* #ORM\OneToOne(targetEntity="Vendor\SystemBundle\Entity\Upload",cascade={"all"})
*/
private $myfile;
and then do
php app/console doctrine:generate:entities Your\Entity\Path\
php app/console doctrine:schema:update --force
So it re-creates the getters and setters and delete the constrain from the db
