我可以'；t在我的数据库symfony 2.4和条令中插入数据

当我检查数据库时，我找不到任何行，也找不到数据im使用symfony 2.4和doctrine2我不知道的错误在哪里

这是我的位置类型

<?php
namespace carRental'MainBundle'Form;
use Symfony'Component'Form'AbstractType;
use Symfony'Component'Form'FormBuilderInterface;
use Symfony'Component'OptionsResolver'OptionsResolverInterface;
class LocationType extends AbstractType {
    /**

     * @param array $options
     */
public function buildForm(FormBuilderInterface $builder, array $options) {
    $builder
            ->add('fullName', 'text', array(
                'attr' => array(
                    'class' => 'form-control'
                )
            ))
            ->add('email', 'email', array(

            ->add('phone', 'number', array(
                'attr' => array(
                    'class' => 'form-control'
        )))
            ->add('placeLivrai', 'text', array(

                )
            ))
            ->add('country', 'country', array(

            ->getForm();
}
/**

public function setDefaultOptions(OptionsResolverInterface $resolver) {
    $resolver->setDefaults(array(

    ));
}
/**
 * @return string
 */
public function getName() {
    return 'carrental_mainbundle_location';
}

}

这是我的位置Action

 public function locationAction() {
    // Reservation Form
    $em = $this->getDoctrine()->getManager();
    $location = new Location();
    $form = $this->createForm(new LocationType(), $location);
    $request = $this->getRequest();
    if ($request->isMethod('POST')) {
        $form->handleRequest($request);
        if ($form->isValid()) {
            $em->persist($form->getData());
            $em->flush();
             $this->get('session')->getFlashBag()->add('Reservation', 'Votre réservation a été bien envoyé');
             /* return $this->redirect($this->generateUrl('home_main_homepage')); */
        }
    }
    return $this->render('carRentalMainBundle:Main:location.html.twig', array(
                'form' => $form->createView(),
    ));
}

这是我的观点

    {% extends 'carRentalMainBundle::layout.html.twig' %}
{% block body %}
<div class="container">
{% for flashMessage in app.session.flashbag.get('Reservation') %}
    <ul><li class="alert-success">
    {{flashMessage}}
        </li></ul>
{% endfor%}
    <br/>
    <div class="col-md-4">
