Symfony2\Doctrine - Retrieving User Roles - php

Question

I'm trying to set up my User entity to use roles, and following the documentation at http://symfony.com/doc/current/cookbook/security/entity_provider.html
Users work fine, and if I hardcode the $roles value everything works as expected, log in/out is good, etc. But, if I try and retrieve the roles through a many-to-many relationship as outlined in the documentation I get back null.
I should also mention that after creating the entities when I ran 'php app/console doctrine:schema:update --force' it created the role table, but not the 'user_role' table as it said it would. I went ahead and created it manually and entered a row for the user I was testing with, but that was my first clue something wasn't working. It's really frustrating because I followed the documentation and it looks like it should work.
The error I get back while trying to log-in is:
FatalErrorException: Error: Call to a member function toArray() on a non-object
Which points to return $this->roles->toArray() in the user entity.
My User Entity (the relevant bits):
use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\Security\Core\User\UserInterface;
/**
*
* #ORM\Table()
* #ORM\Entity(repositoryClass="ACME\MyBundle\Entity\UserRepository")
*
*/
class User implements UserInterface, \Serializable
{
...
/**
* #ORM\ManyToMany(targetEntity="Role", inversedBy="users")
*
*/
private $roles;
...
/**
* Constructor
*/
public function __construct()
{
$this->roles = new ArrayCollection();
}
public function getRoles()
{
return $this->roles->toArray();
}
...
}
My Role Entity:
use Symfony\Component\Security\Core\Role\RoleInterface;
use Doctrine\Common\Collections\ArrayCollection;
use Doctrine\ORM\Mapping as ORM;
/**
* #ORM\Table(name="role")
* #ORM\Entity()
*/
class Role implements RoleInterface
{
/**
* #ORM\Column(name="id", type="integer")
* #ORM\Id()
* #ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* #ORM\Column(name="name", type="string", length=30)
*/
private $name;
/**
* #ORM\Column(name="role", type="string", length=20, unique=true)
*/
private $role;
/**
* #ORM\ManyToMany(targetEntity="User", mappedBy="roles")
*/
private $users;
public function __construct()
{
$this->users = new ArrayCollection();
}
/**
* #see RoleInterface
*/
public function getRole()
{
return $this->role;
}
/**
* Get id
*
* #return integer
*/
public function getId()
{
return $this->id;
}
/**
* Set name
*
* #param string $name
* #return Role
*/
public function setName($name)
{
$this->name = $name;
return $this;
}
/**
* Get name
*
* #return string
*/
public function getName()
{
return $this->name;
}
/**
* Set role
*
* #param string $role
* #return Role
*/
public function setRole($role)
{
$this->role = $role;
return $this;
}
}
Does anybody see a problem in my code or have experience with this same issue? I'm stuck at the moment.

Answer 1

In your entity Role you have
* #ORM\Table(name="role")
change it to
* #ORM\Table(name="user_role")
because your table name is user_role not role

Answer 2

I had the same probleme and i removed the toArray methode
use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\Security\Core\User\UserInterface;
/**
*
* #ORM\Table()
* #ORM\Entity(repositoryClass="ACME\MyBundle\Entity\UserRepository")
*
*/
class User implements UserInterface, \Serializable
{
...
/**
* #ORM\ManyToMany(targetEntity="Role", inversedBy="users")
*
*/
private $roles;
...
/**
* Constructor
*/
public function __construct()
{
$this->roles = new ArrayCollection();
}
public function getRoles()
{
return $this->roles;//return $this->roles->toArray();
}
...
}
