Form sending OneToMany to Database fails (Symfony2 / Doctrine) - php

Question

I have a form that uploads a file and I am trying to "attach" the correct job id/entity to it, but it seems I don't fully understand the concept of table relations:
My File class
/**
* #ORM\ManyToOne(targetEntity="Job", inversedBy="file")
*/
protected $job;
My Job class:
/**
* #ORM\OneToMany(targetEntity="File", mappedBy="job")
*/
protected $file;
public function __construct()
{
$this->file = new ArrayCollection();
}
I am submitting the form and entering everything into a database:
$em = $this->getDoctrine()->getManager();
$file = new File();
$form = $this->createFormBuilder($file)
->add('file')
->add('job','text')
->add('save', 'submit', array('label' => 'Create Task'))
->getForm();
$form->handleRequest($request);
if ($form->isValid()) {
$job = $em->getRepository("AppBundle:Job")->find($form->getData()->getJob());
$file->setFile($form->getData()->getFile());
$file->setPath($form->getData()->getPath());
$file->setJob($job);
$em->persist($file);
$em->flush();
return $this->redirectToRoute("pendingJobs");
}
Submitting the form ends in a fatal error:
Catchable Fatal Error: Argument 1 passed to AppBundle\Entity\File::setJob() must be an instance of AppBundle\Entity\Job, string given, called in /var/www/html/web2gdv/vendor/symfony/symfony/src/Symfony/Component/PropertyAccess/PropertyAccessor.php on line 410 and defined
I tried debugging what was send with
if ($form->isValid()) {
dump($form->getData());
die();
}
but it does even get to the point?!
What am I doing wrong?
Any hint appreciated!
UPDATE
Thanks to #julien-bourdic I updated my form like this:
/**
* #Route("/job/pending", name="pendingJobs")
*/
public function jobAction(Request $request)
{
$this->denyAccessUnlessGranted('ROLE_ADMIN', null, 'Unable to access this page!');
$em = $this->getDoctrine()->getManager();
$file = new File();
$form = $this->createFormBuilder($file)
->add('file')
->add('job','entity',array(
'class' => 'AppBundle:Job',
'choice_label' => 'id',
))
->add('save', 'submit', array('label' => 'Create Task'))
->getForm();
$form->handleRequest($request);
if ($form->isValid()) {
$job = $em->getRepository("AppBundle:Job")->find($form->getData()->getJob());
$file->setFile($form->getData()->getFile());
$file->setPath($form->getData()->getPath());
$file->setJob($job);
$em->persist($file);
$em->flush();
return $this->redirectToRoute("pendingJobs");
}
$jobs = $em->getRepository("AppBundle:Job")->findBy(array(
'receipt' => true,
'receiptStatus' => true,
));
return $this->render(
'default/pending.html.twig',
array(
'jobs' => $jobs,
'form' => $form->createView(),
)
);
}
The whole purpose of this class is to have a table where the last button each row is an upload form. How can I populate multiple forms from one class, is that even possible? What yould I have to send to the renderfunction?

Answer 1

Try to explicitely define your field job in your form :
->add('job','entity',array(
'class'=>'AppBundle:Job',
'property'=>'id',
)

Answer 2

The problem is that find() returns array, not a Job. Use findOne().
$job = $em->getRepository("AppBundle:Job")->find($form->getData()->getJob());
// $job is and Array
do instead
$job = $em->getRepository("AppBundle:Job")->findOne($form->getData()->getJob());
// $job is Job

Answer 3

You have add('job', 'text') and must have a entity type, not text
First you need have a 'jobs' in the DB. Then you can change to
$form = $this->createFormBuilder($file)
->add('file')
->add('job','entity', array('class' => 'YourBundle:Job'))
->add('save', 'submit', array('label' => 'Create Task'))
->getForm();
or short
$form = $this->createFormBuilder($file)
->add('file')
->add('job')
->add('save', 'submit', array('label' => 'Create Task'))
->getForm();
you will receive select box on the job-field
