Issue in creating User Roles Symfony2 - php

Question

Simple process,
Need to create Users with mapped Roles.
I followed the step from link
http://symfony.com/doc/current/cookbook/security/entity_provider.html
User and Roles table generated but users_roles table is not generated in MySql...
Will i need to create it manually?
Second
I have configured with User table for Authentication
After login it redirects to Error page,
FatalErrorException: Error: Call to a member function toArray() on a non-object in /var/www/vibilling_3/src/ViBillingPortal/AuthenticationBundle/Entity/users.php line 130
I searched, but i cant find any solutions... Below my code
Bill/PortalBundle/Entity/users.php
namespace ViBillingPortal\AuthenticationBundle\Entity;
use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\Security\Core\User\UserInterface;
use Doctrine\Common\Collections\ArrayCollection;

class users implements UserInterface, \Serializable
{
/**

private $id;

You should use a ManyToMany relation, not a ManyToOne if you want to use a join table : http://docs.doctrine-project.org/en/2.0.x/reference/association-mapping.html#many-to-many-bidirectional
For the second error, it's strange as you initialize usersroles as an ArrayCollection in your construct method, it should work.
Could you add a var_dump to look what is stored in this property ?
Why don't you get any setter/getter for usersroles ?
I think you should also read Symfony coding standards : http://symfony.com/doc/current/contributing/code/standards.html. You coding style is not consistent.
