创建用户角色Symfony2时出现问题

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
{
/**
 * @var integer
 */
private $id;

/**

 */
private $username;

/**

 */
private $password;

/**
 * @var string
 */
private $created_date;

/**
 * @ORM\ManyToMany(targetEntity="roles", inversedBy="users")
 * @ORM\JoinTable(name="user_roles")
 */
private $userroles;


public function __construct()
{
    $this->userroles = new ArrayCollection();
}

/**

public function getId()
{
    return $this->id;
}

Answer 1

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.
