Symfony 2 collection with image - editing - forms

Question

I have little problem with my collection form type.
I have relation 1 to many ( product and productImages )
I think that the problem is in my productImages Entity ( if it is possible to solve )
My productImages:
class produktImage
{
/**
* #var integer
*
* #ORM\Column(name="id", type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* #ORM\Column(name="name", type="string", length=255)
*/
private $name;
/**
* #Assert\File(maxSize="6000000")
*/
public $file;
/**
* #ORM\ManyToOne(targetEntity="product", inversedBy="tags")
*/
protected $product;
and the most importatnt method:
public function upload()
{
$this->name = trim(date("dmyGis").rand(1,99999999).'_'.$this->file->getClientOriginalName());
$this->file->move($this->getUploadRootDir(), $this->name);
$move = new resizeImg(1280, 3000, $this->name, $this->getUploadRootDir(), null);
$move->setThumbial(550, 2000, $this->getUploadRootDir().'../small/', null);
$move->setThumbial(200, 2000, $this->getUploadRootDir().'../thumb/', null);
$this->file = null;
}
Form productImage has file field only.
My product entity ( the most importatnt methods )
public function addPhotosum($photos)
{
$photos->setProdukt($this);
$photos->upload($this);
$this->photos->add($photos);
return $this;
}
public function removePhotosum($photos)
{
$this->photos->removeElement($photos);
$photos->removeImg();
}
Ok, but where is my problem.
When I try to add or remove file everything is ok.
If I try to edit file nothing happen. Name and file don't change.
I think it is because Product don't see changes in name ( name is stored in db only ) but I don't know how can I tell him "change name and file when file is diffrent".
Can I use preUpdate or something else?
Someone had similar problem?

Answer 1

Just call the upload() method in your edit action of your controller ..
example :
public function editAction(Request $request, $id)
{
$em = $this->getDoctrine()->getManager();
$entity = $em->getRepository('YourBundle:YourEntity')->find($id);
if (!$entity) {
throw $this->createNotFoundException('Unable to find Your entity.');
}
$editForm = $this->createEditForm($entity);
$editForm->handleRequest($request);
if ($editForm->isValid()) {
$entity->upload()
$entity->persist($entity);
$em->flush();
return $this->redirect($this->generateUrl('your_destination_route', array('id' => $id)));
}
return array(
'entity' => $entity,
'edit_form' => $editForm->createView(),
);
}
I hope it will work for you ..
