Different type expected in Symfony - php

Question

I am trying to create a form using Symfony and Doctrine.
I created a Job class, and a table in mysql which relates to it, using Doctrine. It also made the JobType and JobController, and Routing facility.
I can access the index page, where the jobs are listed, but can't access the new entry page.
Here are the files used for creating the forms.
JobController.php
<?php
namespace AppBundle\Controller;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Method;
use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;
use AppBundle\Entity\Job;
use AppBundle\Form\JobType;
/**
* Job controller.
*
* #Route("/job")
*/
class JobController extends Controller
{
/**
* Lists all Job entities.
*
* #Route("/", name="job_index")
* #Method("GET")
*/
public function indexAction()
{
$em = $this->getDoctrine()->getManager();
$jobs = $em->getRepository('AppBundle:Job')->findAll();
return $this->render('job/index.html.twig', array(
'jobs' => $jobs,
));
}
/**
* Creates a new Job entity.
*
* #Route("/new", name="job_new")
* #Method({"GET", "POST"})
*/
public function newAction(Request $request)
{
$job = new Job();
$jobType = new JobType();
$form = $this->createForm($jobType, $job);
$form->handleRequest($request);
if ($form->isSubmitted() && $form->isValid()) {
$em = $this->getDoctrine()->getManager();
$em->persist($job);
$em->flush();
return $this->redirectToRoute('job_show', array('id' => $job->getId()));
}
return $this->render('job/new.html.twig', array(
'job' => $job,
'form' => $form->createView(),
));
}
/**
* Finds and displays a Job entity.
*

public function showAction(Job $job)
{
$deleteForm = $this->createDeleteForm($job);
return $this->render('job/show.html.twig', array(
'job' => $job,
'delete_form' => $deleteForm->createView(),
));
}
/**

public function editAction(Request $request, Job $job)
{
$deleteForm = $this->createDeleteForm($job);

}
/**

public function deleteAction(Request $request, Job $job)
{
$form = $this->createDeleteForm($job);
$form->handleRequest($request);
if ($form->isSubmitted() && $form->isValid()) {
$em = $this->getDoctrine()->getManager();
$em->remove($job);
$em->flush();
}
return $this->redirectToRoute('job_index');
}
/**

*/
private function createDeleteForm(Job $job)
{
return $this->createFormBuilder()
->setAction($this->generateUrl('job_delete', array('id' => $job->getId())))
->setMethod('DELETE')
->getForm()
;
}
}
JobType.php
namespace AppBundle\Form;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolver;
class JobType extends AbstractType
{
/**
* #param FormBuilderInterface $builder
* #param array $options
*/
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder
->add('category', 'string')
->add('type', 'string')
->add('company', 'string')
->add('logo', 'string')
->add('url', 'string')
->add('position', 'string')
->add('location', 'string')
->add('desciption', 'text')
->add('how_to_apply', 'text')
->add('token', 'string')
->add('is_public', 'boolean')
->add('is_activated', 'boolean')
->add('email', 'string')
->add('expires_at', 'datetime')
->add('created_at', 'datetime')
->add('updated_at', 'datetime')
;
}
/**
* #param OptionsResolver $resolver
*/
public function configureOptions(OptionsResolver $resolver)
{
$resolver->setDefaults(array(
'data_class' => 'AppBundle\Entity\Job'
));
}
/**
* Mandatory in Symfony2
* Gets the unique name of this form.
* #return string
*/
public function getName()
{
return 'add_job';
}
}
This is the error I receive
Thanks!
EDIT:
The content of app/config/services.yml
parameters:
# parameter_name: value
services:
# service_name:
# class: AppBundle\Directory\ClassName
# arguments: ["#another_service_name", "plain_value", "%parameter_name%"]

$editForm = $this->createForm(new JobType(), $job);
This is no longer possible in Symfony 3. In Symfony 3, you always have to pass the fully-qualified class name for form types:
$editForm = $this->createForm(JobType::class, $job);
Also, in your form type you're passing the type name instead of the FQCN of the type classes.
Symfony 3 has just released its first BETA, which means it's very bleeding edge. Also, there are almost zero tutorials for Symfony 3 yet (as it's so extremely bleeding edge). You're reading a Symfony 2 tutorial, so I recommend you to install Symfony 2 instead of 3.
