I have then created a Form EntityType class for the RotaMain object as follows:
<?php
namespace Rota\Bundle\Form\Type;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolverInterface;
class RotaMainType extends AbstractType
{
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder-> add('ReviewDate','date');
$builder->add('RollingWeeks','integer');
$builder->add('StartDate','date');
$builder->add('RestDayCount','integer',array('label' => 'Number of rest days'));
$builder->add('TotalDayCount','integer',array('label' => 'Total number of days in shift pattern'));
$builder->add('rotaShifts','collection',array('type'=> new RotaShiftType(),'label' => false,'allow_add' => true,));
$builder->add('Save','submit');
}
public function setDefaultOptions(OptionsResolverInterface $resolver)
{
$resolver->setDefaults(array(
'data_class' => 'Rota\Bundle\Entity\RotaMain',
));
}
public function getName()
{
return 'rotaMain';
}
}
When I try to set a form with a fully populated RotaMain object:
$form = $this->createForm(new RotaMainType(),$RotaMain);
I get the following 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 Rota\Bundle\Entity\RotaMain. You can avoid this error by setting the "data_class" option to "Rota\Bundle\Entity\RotaMain" or by adding a view transformer that transforms an instance of class Rota\Bundle\Entity\RotaMain to scalar, array or an instance of \ArrayAccess.
I have set the data_class in the RotaMainType object so am not sure where I am going wrong? If I pass an empty RotaMain object to the form it builds as expected.
The population of RotaMain happens in the controller. The form is part one of two part process. If user has completed first part gone away and come back I want reutnr the first part fo them to review before going onto the second part of the process. Controller action:
public function setRotaAction(Request $request,$userId)
{
//Check to see if user has part set up a rota - return completed form for review
$RotaMainRepos = $this->getDoctrine()->getManager()->getRepository("RotaBundle:RotaMain");
$id = $this->getUser()->getID();
$criteria = array("myUserId"=>$id);
$result = $RotaMainRepos->findBy($criteria);
if($result == null)
{
$RotaMain = new RotaMain();
$RotaMain->setmyUserId($userId);
$form = $this->createForm(new RotaMainType(),$RotaMain);
}
else
{
$RotaMain = $result[0];
$rotashiftRepo = $this->getDoctrine()->getManager()->getRepository("RotaBundle:RotaShift");
$rotaShifts = $rotashiftRepo->findByRotaMain($RotaMain);
foreach($rotaShifts as $rotaShift)
{
$RotaMain->addRotaShift($rotaShift);
}
$form = $this->createForm(new RotaMainType(),$RotaMain);
}
$form->handleRequest($request);
if($form->isValid())
{
$early = $form->getData();
$em = $this->getDoctrine()->getManager();
$em->persist($early);
$shifts = $early->getRotaShifts();
foreach($shifts as $shift)
{
$shift->setRotaMain($early);
$em->persist($shift);
}
$em->flush();
$shiftOrder = new ShiftOrder($shifts,$early->getRestDayCount(),$early->getTotalDayCount());
return $this->render("RotaBundle:Default:shiftOrder.html.twig",array("shiftOrder" => $shiftOrder));
}
return $this->render('RotaBundle:Default:setRota.html.twig',array("form" => $form->createView(),));
}
You have to bind a newly created or existing entity/object of the same type as the configured data_class to your form.
If you don't set the variable you're passing to your form to an object of the expected data_class symfony won't create the object but throw this exception.
In your case you might want to use a SensioFrameworkExtraBundle's @ParamConverter to fetch your entity from database and have your controller cleaned up.
/**
* @Route("/whatever/{id}")
* @ParamConverter("rotaMain", class="RotaBundle:RotaMain", options={"mapping": {"MyUserId": "id"}})
*/
public function editAction(RotaMain $rotaMain, Request $request)
{
$form = $this->createForm(new RotaMainType(), $rotaMain);
$form->handleRequest($request);
if ($form->isValid()) {
//
}
}
... or ...
public function newAction(Request $request)
{
$form = $this->createForm(new RotaMainType(), $rotaMain = new RotaMain());
$form->handleRequest($request);
if ($form->isValid()) {
//
