Symfony2 form processing

Question

I'm having trouble processing my contact form, a simple one though. I have spent much time trying to figure out what is wrong with my code but I've not been able to find a way out. My object is not receiving data. I'm having the following exception:

An exception occurred while executing 'INSERT INTO contact (email, name, message, date) VALUES (?, ?, ?, ?)' with params [null, null, null, "2016-09-19 00:08:48"]:

SQLSTATE[23000]: Integrity constraint violation: 1048 Column 'email' cannot be null

Below is my code:

 
    
        
            
                Email
                
                {{ form_errors(form.email) }}
            
        
        
            
                Nom 
                
                {{ form_errors(form.name) }}
            
        
    
    
        Message
        
        {{ form_errors(form.message) }}

The controller:

public function contactAction(Request $request)
{
    // Retrieving POST data
    //$postData = $request->request->get('email');

    $contact = new Contact();

    $form = $this->createForm(new ContactType(), $contact);

    if ($form->handleRequest($request)) {

        /*if ($this->get('ap_platform.antispam')->isSpam($contact->getMessage())) {
            throw new \Exception('The field email is either empty or its content is too short');
        }*/

        $em = $this->getDoctrine()->getManager();
        $em->persist($contact);
        $em->flush();

        //var_dump($contact->getEmail());exit;

        $request->getSession()->getFlashBag()->add('notice', 'Votre message a été envoyé !');

        $mailer = $this->get('mailer');

        $message =  \Swift_Message::newInstance()
            ->setSubject('Message venant du formulaire de contact de chyqat.com')
            ->setFrom('chyqat@chyqat.com')
            ->setTo('patrickbassoukissa@yahoo.fr')
            ->setBody("Nouveau message provenant de ".$contact->getName()."
  Adresse Email : ".$contact->getEmail()." 
Son message:
 ".$contact->getMessage()."")
        ;

        $mailer->send($message);
    }

    return $this->render("APPlatformBundle:Public:contact.html.twig", array(
        'form' => $form->createView()
    ));
}

ContactType.php file:

class ContactType extends AbstractType
{
    /**
     * @param FormBuilderInterface $builder
     * @param array $options
     */
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder
            ->add('email',       'email')
            ->add('message',     'textarea')
            ->add('name',        'text')
        ;
    }

/**
 * @param OptionsResolverInterface $resolver
 */
public function setDefaultOptions(OptionsResolverInterface $resolver)
{
    $resolver->setDefaults(array(
        'data_class' => 'Advertproject\PlatformBundle\Entity\Contact'
    ));
}

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

Contact object:

date = new \Datetime();
    }

    /**
     * Set email
     * @Assert\NotBlank()
     * @param string $email
     * @return Contact
     */
    public function setEmail($email)
    {
        $this->email = $email;

        return $this;
    }

    /**
     * Get email
     *
     * @return string 
     */
    public function getEmail()
    {
        return $this->email;
    }

    /**
     * Set name
     *
     * @param string $name
     * @return Contact
     */
    public function setName($name)
    {
        $this->name = $name;

        return $this;
    }

    /**
     * Get name
     *
     * @return string 
     */
    public function getName()
    {
        return $this->name;
    }

    /**
     * Set message
     *
     * @param string $message
     * @return Contact
     */
    public function setMessage($message)
    {
        $this->message = $message;

        return $this;
    }

    /**
     * Get message
     *
     * @return string 
     */
    public function getMessage()
    {
        return $this->message;
    }

    /**
     * Set date
     *
     * @param \DateTime $date
     * @return Contact
     */
    public function setDate($date)
    {
        $this->date = $date;

        return $this;
    }

    /**
     * Get date
     *
     * @return \DateTime 
     */
    public function getDate()
    {
        return $this->date;
    }

    /**
     * Get id
     *
     * @return integer 
     */
    public function getId()
    {
        return $this->id;
    }
}

Can anyone help me finding out what is wrong with my code?

Below is what I got after running var_dump($form->getData()) before calling flush() method

object(Advertproject\PlatformBundle\Entity\Contact)#1955 (5) { ["id":protected]=> NULL ["email":protected]=> NULL ["name":protected]=> NULL ["message":protected]=> NULL ["date":protected]=> object(DateTime)#1956 (3) { ["date"]=> string(26) "2016-09-18 20:49:32.000000" ["timezone_type"]=> int(3) ["timezone"]=> string(13) "Europe/London" } }

you should use following code in your html.twig page

     
         {{ form_start(form) }}
         {{ form_errors(form) }}
         {{ form_widget(form) }}
         {{ form_end(form) }}

check following Symfony Documentation for more ways to render forms.
