Error while persisting data into database in symfony2 - php

Question

I have created an update password form and whenever I try to submit the data I got error like The class XXX was not found in the chain configured namespaces. What am I doing wrong in here? The error occurs when I try to save the data in the database. I have tried the answer from implementing update password
Here are my codes.
This is my ChangePasswordType.php
<?php
namespace RetailMapping\Bundle\UserBundle\Form;
use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;
use Symfony\Component\OptionsResolver\OptionsResolverInterface;
class ChangePasswordType extends AbstractType
{
/**
* #param FormBuilderInterface $builder
* #param array $options
*/
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder->add('oldPassword', 'password');
$builder->add('newPassword', 'repeated', array(
'type' => 'password',
'invalid_message' => 'The password fields must match.',
'required' => true,
'first_options' => array('label' => 'Password'),
'second_options' => array('label' => 'Repeat Password'),
));
}
/**
* #param OptionsResolverInterface $resolver
*/
public function setDefaultOptions(OptionsResolverInterface $resolver)
{
$resolver->setDefaults(array(
'data_class' => 'RetailMapping\Bundle\UserBundle\Form\Model\ChangePassword',
));
}
/**
* #return string
*/
public function getName()
{
return 'retailmapping_bundle_userbundle_password_chnage';
}
}
This is my ChangePassword.php
<?php
namespace RetailMapping\Bundle\UserBundle\Form\Model;
use Symfony\Component\Security\Core\Validator\Constraints as SecurityAssert;
use Symfony\Component\Validator\Constraints as Assert;
class ChangePassword
{
/**
* #SecurityAssert\UserPassword(
* message = "Wrong value for your current password"
* )
*/
protected $oldPassword;
/**
* #Assert\Length(
* min = 6,
* minMessage = "Password should by at least 6 chars long"
* )
*/
protected $newPassword;
public function setOldPassword($oldPassword)
{
$this->oldPassword = $oldPassword;
}
public function getOldPassword()
{
return $this->oldPassword;
}
public function setNewPassword($newPassword)
{
$this->newPassword = $newPassword;
}
public function getNewPassword()
{
return $this->newPassword;
}
}
This is my UserController.php
<?php
namespace RetailMapping\Bundle\UserBundle\Controller;
use Symfony\Bundle\FrameworkBundle\Controller\Controller;
use RetailMapping\Bundle\UserBundle\Form\ChangePasswordType;
use Symfony\Component\HttpFoundation\Request;
use RetailMapping\Bundle\UserBundle\Form\Model\ChangePassword;
class UserController extends Controller
{
public function editPasswordAction(Request $request)
{
$form = $this->createForm(new ChangePasswordType(), new ChangePassword());
$form->handleRequest($request);
if ($form->isSubmitted() && $form->isValid()) {
$data = $form->getData();
$form->getData();
$em = $this->getDoctrine()->getManager();
$em->persist($data);
$em->flush();
dump($form->getData());
die;
}
return $this->render('User/editPassword.html.twig', [
'form' => $form->createView(),
]);
}
}

By default your entity is mapped to Entity namespace.
DoctrineExtension code on github
protected function getMappingObjectDefaultName()
{
return 'Entity';
}
You need to place your ChangePassword.php within Entity folder.
