I have a problem using Symfony 2. When I try to populate a form with data coming from an Entity I get this error:
"The form's view data is expected to be of type scalar, array or an instance of \ArrayAccess, but is an instance of class DateTime. You can avoid this error by setting the "data_class" option to "DateTime" or by adding a view transformer that transforms an instance of class DateTime to scalar, array or an instance of \ArrayAccess."
I haven't much experience with Symfony 2. To create the Entities I am using YAML option.
Thanks.
The controller code:
public function editAction($id)
{
$em = $this->getDoctrine()->getManager();
$candidate = $em->getRepository('OUProjectBundle:Candidate')->findOneById($id);
$form = $this->createForm(new CandidateType(), $candidate);
return $this->render('MyProjectBundle:Candidate:new.html.twig', array(
'form' => $form->createView(),
));
}
The CandidateType class:
namespace My\ProjectBundle\Form;
use Symfony\Component\Form\AbstractType;
use My\ProjectBundle\Entity\Candidate;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolverInterface;
use Doctrine\ORM\EntityRepository;
class CandidateType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder->add('name', 'text', array('label'=>'Name:'));
$builder->add('surname', 'text', array('label'=>'Surname:'));
$builder->add('email', 'text', array('label'=>'Email:'));
$builder->add('phone', 'text', array('label'=>'Telephone:'));
$builder->add('DOB', 'text', array('label'=>'Date of Birth:'));
$builder->add('address', 'text', array('label'=>'Address'));
$builder->add('town', 'text', array('label'=>'Town:'));
$builder->add('city', 'text', array('label'=>'City:'));
$builder->add('post_code', 'text', array('label'=>'Post Code:'));
$builder->add('file', 'file', array('label' => 'CV file (.docx)', 'required' => true));
}
public function getName()
{
return 'candidate';
}
public function getDefaultOptions(array $options)
{
return array(
'data_class' => 'My\ProjectBundle\Entity\Candidate',
);
}

In your CandidateType class, field DOB as text type, in entity it's in datetime format you can use something like this
$builder->add('DOB', 'date', array('input' => 'datetime','label'=>'Date of Birth:'));
please refer this date Field Type manual
