How to get data from select field Symfony

Hi everyone i have problem. I need to take data from Select field filled by entity class.

This is my entity: It's dictionary with months and first and last day.

Entity

namespace accountant\ReportBundle\Entity;

use Doctrine\ORM\Mapping as ORM;

/**
 * @ORM\Entity
 */
class Calendar
{
    /**
     * @var integer
     *
     * @ORM\Column(name="id", type="integer")
     * @ORM\Id
     * @ORM\GeneratedValue(strategy="AUTO")
     */
    private $id;

    /**
     * @var string
     *
     * @ORM\Column(name="month", type="string", length=255)
     */
    private $month;
}

I load fixtures to this table to db and create formBuilder:

FormType

class ReportFormType extends AbstractType
{
     public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add('month','entity', array(
                'class' => 'ReportBundle:Calendar',
                'property' => 'month',
                'expanded' => false,
                'multiple' => false
            ));
    }
}

Now I want to get data from selected month to, but $data is null:

Controller

 /**
 * @Route("/report", name="report")
 * @Template()
 */
public function indexAction(Request $request)
{
    $form = $this->createForm(new ReportFormType());
    $form->handleRequest($request);
    $data = $form->getData();

    var_dump($data);    // $data is null!       

    return array('form' => $form->createView());
}

TWIG

<form method="get" action="{{ path('report') }}">
    <div class="form-group">
        {{ form_row(form.month, {'label': 'Select Month:', 'attr': {'class': 'form-control'}}) }}
    </div>
    <div class="form-group">
        <input type="submit" value="Show Report" class="btn btn-warning btn-block"/>
    </div>
</form>

UPDATE 1

I add 'data_class' but i still get NULL. 

 public function buildForm(FormBuilderInterface $builder, array $options)
{
    $builder
        ->add('month','entity', array(
            'class' => 'ReportBundle:Calendar',
            'choice_label' => 'month',
            'expanded' => false,
            'multiple' => false,
        ));
}

/**
 * @param OptionsResolver $resolver
 */
public function configureOptions(OptionsResolver $resolver)
{
   $resolver->setDefaults(array(
       'data_class' => Calendar::class
   ));
}

This is my Controller now. 

public function indexAction(Request $request)
{
    $form = $this->createForm(new ReportFormType());
    $form->handleRequest($request);
    $data = $form->get('month')->getData();
    // i check data
    var_dump($data);

    return array(
        'form' => $form->createView());
}

UPDATE 2

I solved my problem i change my form in template for this:

<form method="post" action="{{ path('report') }}" novalidate="novalidate">
{{ form_errors(form) }}
<div class="form-group">
{{ form_row(form.month, {'label': 'Select month', 'attr': {'class': 'form-control'}}) }}
{{ form_rest(form) }}
</div>
<div class="form-group">
    <input type="submit" value="Show report" class="btn btn-warning btn-block"/>
</div>

I change method to post and add form_rest

change your form like :

use accountant\ReportBundle\Entity\Calendar;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolver;

class ReportFormType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add('month','entity', array(
                'class' => 'ReportBundle:Calendar',
                'property' => 'month',
                'expanded' => false,
                'multiple' => false
            ));
    }

    public function configureOptions(OptionsResolver $resolver)
    {
        $resolver->setDefaults(array(
            'data_class'=> Calendar::class,
        ));
    }
}

Keep in mind to have first letter of namespace sections in CAPS (Accountant instead of accountant).

Update

According to OP's comment, you may get month data in your controller:

Symfony 2

public function indexAction(Request $request)
{
    // ...

    $data = $form->get('month')->getData();

    // ...
}

Symfony 3 & 4

public function indexAction(Request $request)
{
    // ...

    $data = $form['month']->getData();

    // ...
}
