Symfony2 File Upload with own Entity

I have one entity "Task" and another "Attachments". I want to store all attachments in their own table associated with their task and user. So I created this entity Class:

<?php

namespace Seotool\MainBundle\Entity;

use Doctrine\Common\Collections\ArrayCollection;
use Symfony\Component\HttpFoundation\File\UploadedFile;
use Symfony\Component\Validator\Constraints as Assert;
use Doctrine\ORM\Mapping as ORM;

/**
 * @ORM\Entity
 * @ORM\Table(name="attachments")
 */
class Attachments {

/**
 * @ORM\Column(type="integer")
 * @ORM\Id
 * @ORM\GeneratedValue(strategy="AUTO")
 */
protected $id;

/**
 * @ORM\Column(type="string", length=255)
 * @Assert\NotBlank
 */
public $name;

/**
 * @ORM\Column(type="string", length=255, nullable=true)
 */
public $path;

/**
 * @ORM\ManyToOne(targetEntity="User", inversedBy="attachments")
 * @ORM\JoinColumn(name="user", referencedColumnName="id")
 */
protected $User;

/**
 * @ORM\ManyToOne(targetEntity="User", inversedBy="attachments")
 * @ORM\JoinColumn(name="editor", referencedColumnName="id")
 */
protected $Editor;

/**
 * @ORM\ManyToOne(targetEntity="Task", inversedBy="attachments")
 * @ORM\JoinColumn(name="task", referencedColumnName="id")
 */
protected $Task;

/**
 * @Assert\File(maxSize="6000000")
 */
private $file;

/**
 * Sets file.
 *
 * @param UploadedFile $file
 */
public function setFile(UploadedFile $file = null)
{
    $this->file = $file;
}

/**
 * Get file.
 *
 * @return UploadedFile
 */
public function getFile()
{
    return $this->file;
}

public function getAbsolutePath()
{
    return null === $this->path
        ? null
        : $this->getUploadRootDir().'/'.$this->path;
}

public function getWebPath()
{
    return null === $this->path
        ? null
        : $this->getUploadDir().'/'.$this->path;
}

protected function getUploadRootDir()
{
    // the absolute directory path where uploaded
    // documents should be saved
    return __DIR__.'/../../../../web/'.$this->getUploadDir();
}

protected function getUploadDir()
{
    // get rid of the __DIR__ so it doesn't screw up
    // when displaying uploaded doc/image in the view.
    return 'uploads/documents';
}

....

In my Form Type for my Task Form I want to add now the file upload. But how can I do this? I can't add $builder->add('Attachment', 'file'); because it's not the same entity. So how can I do it, so that I have in my FormType of Entity Task the upload field which stores the uploaded data in the table of Entity Class Attachment??

EDIT

this is my Controller:

/**
@Route(
 *     path = "/taskmanager/user/{user_id}",
 *     name = "taskmanager"
 * )
 * @Template()
 */
public function taskManagerAction($user_id, Request $request)
{

     /* #### NEW TASK #### */

    $task = new Task();
    $attachment = new Attachments();

    $task->getAttachments()->add($attachment);
    $addTaskForm = $this->createForm(new TaskType(), $task);

    $addTaskForm->handleRequest($request);

    if($addTaskForm->isValid()):

        /* User Object of current Users task list */
        $userid = $this->getDoctrine()
            ->getRepository('SeotoolMainBundle:User')
            ->find($user_id);

        $task->setDone(FALSE);
        $task->setUser($userid);
        $task->setDateCreated(new \DateTime());
        $task->setDateDone(NULL);
        $task->setTaskDeleted(FALSE);

        $attachment->setTask($task);
        $attachment->setUser($userid);

        $em = $this->getDoctrine()->getManager();
        $em->persist($task);
        $em->persist($attachment);
        $em->flush();

        $this->log($user_id, $task->getId(), 'addTask');

        return $this->redirect($this->generateUrl('taskmanager', array('user_id' => $user_id)));

    endif;
}

Ok, that's because you have to initialize new instance of TaskType in your controller - there are no attachments at the beginning that are assigned to this task.

public function newAction(Request $request)
{
    $task = new Task();

    $attachment1 = new Attachment();
    $task->getAttachments()->add($attachment1);
    $attachment2 = new Attachment();
    $task->getAttachments()->add($attachment2);
    // create form
    $form = $this->createForm(new TaskType(), $task);

    $form->handleRequest($request);
    ...
}

Now there should be 2 file input for new attachments.

I added a new Form Type: AttachmentsType.php

<?php
namespace Seotool\MainBundle\Form\Type;

use Doctrine\ORM\EntityRepository;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolverInterface;

class AttachmentsType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
    $builder->add('name', 'text');
    $builder->add('file', 'file');
}

public function setDefaultOptions(OptionsResolverInterface $resolver)
{
    $resolver
            ->setDefaults(array(
                'data_class' => 'Seotool\MainBundle\Entity\Attachments'
            ));
}

public function getName()
{
    return 'attachments';
}
}

And used this for embbing it into my form builder of the TaskType.php

$builder->add('attachments', 'collection', array(
    'type' => new AttachmentsType(),
));

But my output only gives me following HTML:

 <div class="form-group"><label class="control-label required">Attachments</label><div id="task_attachments"></div></div><input id="task__token" name="task[_token]" class="form-control" value="brHk4Kk4xyuAhST3TrTHaqwlnA03pbJ5RE4NA0cmY-8" type="hidden"></form>

You should rename your entity from Attachments to Attachment as it would be storing data of only one attachment.

In your case you need Symfony2 form collection type to allow adding attachment in task form (TaskType):

$builder->add('attachments', 'collection', array(
    'type' => new AttachmentType(),
    // 'allow_add' => true,
    // 'allow_delete' => true,
    // 'delete_empty' => true,
));

You will also need to create AttachmentType form type for single attachment entity.

Doc of collection field type: http://symfony.com/doc/current/reference/forms/types/collection.html More information about embedding form collection you can find on: http://symfony.com/doc/current/cookbook/form/form_collections.html

Then also read sections:
