Doctrine in laravel, getting all user's roles - laravel

Question

I have a simple project in laravel 5.4 with Doctrine 2.0. I have three tables: users, roles, user_roles. Screenshot from tables schemas from HEIDISQL I show below:
users:
roles:
user_roles:
I have three Entities classes for each table of course:
<?php
namespace TodoList\Http\Entities;
use Doctrine\Common\Collections\ArrayCollection;
use Doctrine\ORM\Mapping as ORM;
/**
* #ORM\Entity
* #ORM\Table(name="users")
*/
class User
{
/**
* #ORM\Id
* #ORM\GeneratedValue
* #ORM\Column(type="integer")
*
*/
private $id;
/**
*
* #ORM\Column(type="string")
*
*/
private $name;
/**
*
* #ORM\Column(type="string")
*
*/
private $email;
/**
* #ORM\OneToMany(targetEntity="Task", mappedBy="user", cascade={"persist"})
* #var ArrayCollection|Task[]
*/
private $tasks;
/**
* #ORM\OneToMany(targetEntity="UserRole", mappedBy="user")
*/
protected $user_roles;
/**
* User constructor
* #param #name
* #param #email
* #param $password
*/
public function __construct($name, $email) {
$this->name = $name;
$this->email = $email;
$this->tasks = new ArrayCollection();
$this->user_roles = new ArrayCollection();
}
/**
*
* #return mixed
*
*
*/
public function getName()
{
return $this->name;
}
/**
* #return mixed
*/
public function getEmail()
{
return $this->email;
}
/**
* #return mixed
*/
public function getTasks()
{
return $this->tasks;
}
public function addTask(Task $task)
{
if(!$this->tasks->contains($task)) {
$task->setUser($this);
$this->tasks->add($task);
}
}
public function getId(){
return $this->id;
}
public function getUserRoles(){
return $this->user_roles;
}
}
<?php
namespace TodoList\Http\Entities;
use Doctrine\Common\Collections\ArrayCollection;
use Doctrine\ORM\Mapping as ORM;
/**
* #ORM\Entity
* #ORM\Table(name="roles")
*
*/
class Role{
/**
* #ORM\Id
* #ORM\Column(type="integer")
* #ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* #var string
*
* #ORM\Column(name="name", type="string")
*/
private $name;
/**
* #var string
*
* #ORM\Column(name="description", type="text")
*/
private $description;
/**
* #ORM\OneToMany(targetEntity="UserRole", mappedBy="role",cascade={"persist"})
*/
protected $user_roles;
public function getId(){
return $this->id;
}
public function getName(){
return $this->name;
}
public function getDescription(){
return $this->description;
}
}
<?php
namespace TodoList\Http\Entities;
use Doctrine\Common\Collections\ArrayCollection;
use Doctrine\ORM\Mapping as ORM;
/**
* #ORM\Entity
* #ORM\Table(name="user_roles")
*/
class UserRole
{
/**
* #var integer
*
* #ORM\Column(name="id", type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
*
* #ORM\ManyToOne(targetEntity="User", inversedBy="user_roles")
* #ORM\JoinColumn(name="user_id", referencedColumnName="id")
*
*/
private $user;
/**
*
* #ORM\ManyToOne(targetEntity="Role", inversedBy="user_roles")
* #ORM\JoinColumn(name="role_id", referencedColumnName="id")
*/
private $role;
public function setUser(User $user)
{
$this->user = $user;
return $this;
}
/**
* Get user
*
* #return \NVC\UserBundle\Entity\User
*/
public function getUser()
{
return $this->user;
}
/**
* Set recipe
*
* #param \NVC\RecipeBundle\Entity\Recipe $recipe
* #return UserRecipeAssociation
*/
public function setRole(Role $role)
{
$this->role = $role;
return $this;
}
/**
* Get recipe
*
* #return \NVC\RecipeBundle\Entity\Recipe
*/
public function getRole()
{
return $this->role;
}
}
I have a problem when I'm trying retrieve roles of particular user by doctrine Entity Managar. I'm trying to do that in that way:
public function showUserRoles(EntityManagerInterface $em){
$userRoles = $em->getRepository('\TodoList\Http\Entities\UserRole');
$userRoles->findBy(['user' => 2]);
//count($userRole);
}
There is an error from method findBy
Error message is:
(1/1) FatalErrorException
Doctrine\Common\Proxy\AbstractProxyFactory::getProxyDefinition():
Failed opening required
'C:\xampp\htdocs\Project\storage\proxies__CG__TodoListHttpEntitiesRole.php'
(include_path='C:\xampp\php\PEAR')
Is anything wrong with my Entities? I don't know how could I solve that problem. Could someone help me with that?
I would be very greateful
Best regards ;)

You need to set folder C:\xampp\htdocs\Project\storage\proxies\ as writable and then you need to generate proxies by console command:
doctrine:generate:proxies
