Save copy of entity doctrine/symfony2 - php

Question

I want to keep the previous version of an entity. When the 'old' entity is updated I want to save it with the same id but with a different revision number so it looks something like this
id: 1 revision_number: 1
id: 1 revision_number: 2
This is the entity
namespace AppBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
use Doctrine\Common\Collections\ArrayCollection;
/**
* Form
*
* #ORM\Table()
* #ORM\Entity
* #ORM\HasLifecycleCallbacks
*/
class Form
{
/**
* #var integer
*
* #ORM\Column(name="id", type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**

*
* #ORM\Column(name="name", type="string", length=255)

Is there a way I can do what I described?

Answer 1

I think what you may need is Loggable extension for Doctrine. Check this link:
https://github.com/Atlantic18/DoctrineExtensions/blob/master/doc/loggable.md
Loggable behavior tracks your record changes and is able to manage versions.
Using loggable behavior you can revert version from your repository with revert() method. You can find many examples on site I gave you the link above.

Answer 2

If you dont fancy using a 3rd party bundle for this:
your ID's will still have to be unique. If you need to track where the copy originated from then you could add a new parameter.
Once you have decided upon this, I would simply clone it, alter the revision number and add the original id if thats which way you want to go and then persist it.
class Form {
// ....
$orig_id = null;
// any getters/setters you need
// .....
}
then in the controller:
public function copyEntity($entity) {
$new_ent = clone $entity;
$new_ent->setOrigId( $entity->getId() );
$new_ent->setRevision( true ); // I would probably bin this as origId being !== null would do the same job
$this->entityManager->persist( $new_ent );
$this->entityManager->flush();
// .....
}
