Symfony2 Pre populate form with data from model?

Question

I have a ProfileType as follows:

namespace Site\UserBundle\Form\Type;

use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilder;

class ProfileType extends AbstractType
{
    public function buildForm(FormBuilder $builder, array $options)
    {       
        $builder->add('facebook', 'text', array('required'=>false))
            ->add('myspace', 'text', array('required'=>false))
            ->add('twitter', 'text', array('required'=>false))
            ->add('soundcloud', 'text', array('required'=>false))
            ->add('youtube', 'text', array('required'=>false))
            ->add('website', 'text', array('required'=>false))
            ->add('bio', 'textarea', array('required'=>false));
    }

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

and I want to pre populate the form fields with data that is already in the database so it is visible in the form.

My controller:

namespace Site\UserBundle\Controller;

use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Symfony\Component\Security\Core\SecurityContext;
use Symfony\Component\HttpFoundation\Request;
use Site\UserBundle\Entity\Profile;
use Site\UserBundle\Form\Type\ProfileType;

class ProfileController extends Controller
{
    public function editAction()
    {           
        $em = $this->getDoctrine()->getEntityManager();
        $editprofile = $em->getRepository('SiteUserBundle:Profile')->findOneByUser($user = $this->get('security.context')->getToken()->getUser()->getId());

        $form = $this->createForm(new ProfileType(), $editprofile);

        $form->bindRequest($this->getRequest());
            if ($form->isValid()) {
                $editprofile->setUpdated(new \DateTime("now"));
                $em->flush();

                return $this->redirect($this->generateUrl('SiteUserBundle_login'));
            }

        return $this->render(
            'SiteUserBundle:Default:editprofile.html.twig', 
            array('form' => $form->createView())
        );
    }
}

Any ideas? I thought this way would be easier to update a users profile.

Solution

Replace

findOneByUser($id)

by

find($id)

Also try passing the $id as a slug from url to your Action. url: example.com/page/id

sampleAction($id){}
