Relation Many to Many Bidirectional Symfony 3 - php

Question

I'm using Symfony 3 with Doctrine. I have 2 entities in my application, User and Role. I need to make a bidirectional relationship many to many.
I consulted the doctrine documentation.Here is the code:
class Rol
{
/**
* #var int
*
* #ORM\Column(name="id", type="integer")
* #ORM\Id
* #ORM\GeneratedValue(strategy="AUTO")
*/
private $id;
/**
* #var string
*
* #ORM\Column(name="nombre", type="string", length=255, unique=true)
*/
private $nombre;
/**
* #var string
*
* #ORM\Column(name="descripcion", type="string", length=255)
*/
private $descripcion;
/**
* #ORM\ManyToMany(targetEntity="Funcionalidad", inversedBy="rolesUsuario")
* #ORM\JoinTable(name="rol_funcionalidad")
*/
private $funcionalidades;
/**
* #ORM\ManyToMany(targetEntity="Usuario", mappedBy="rolesUsuario")
*/
private $usuarios;
public function getAttributes()
{
return get_class_vars(__CLASS__);
}
/**
* Get id
*
* #return int
*/
public function getId()
{
return $this->id;
}
/**
* Set nombre
*
* #param string $nombre
*
* #return Rol
*/
public function setNombre($nombre)
{
$this->nombre = $nombre;
return $this;
}
/**
* Get nombre
*
* #return string
*/
public function getNombre()
{
return $this->nombre;
}
/**
* Set descripcion
*
* #param string $descripcion
*
* #return Rol
*/
public function setDescripcion($descripcion)
{
$this->descripcion = $descripcion;
return $this;
}
/**
* Get descripcion
*
* #return string
*/
public function getDescripcion()
{
return $this->descripcion;
}
/**
* #return string
*/
public function __toString()
{
return $this->getNombre();
}
/**
* Constructor
*/
public function __construct()
{
$this->funcionalidades = new \Doctrine\Common\Collections\ArrayCollection();
$this->usuarios = new \Doctrine\Common\Collections\ArrayCollection();
}
/**
* Add funcionalidade
*
* #param \CECMED\SeguridadBundle\Entity\Rol $funcionalidade
*
* #return Rol
*/
public function addFuncionalidade(\CECMED\SeguridadBundle\Entity\Rol $funcionalidade)
{
$this->funcionalidades[] = $funcionalidade;
return $this;
}
/**
* Remove funcionalidade
*
* #param \CECMED\SeguridadBundle\Entity\Rol $funcionalidade
*/
public function removeFuncionalidade(\CECMED\SeguridadBundle\Entity\Rol $funcionalidade)
{
$this->funcionalidades->removeElement($funcionalidade);
}
/**
* Get funcionalidades
*
* #return \Doctrine\Common\Collections\Collection
*/
public function getFuncionalidades()
{
return $this->funcionalidades;
}
/**
* Add usuario
*
* #param \CECMED\SeguridadBundle\Entity\Usuario $usuario
*
* #return Rol
*/
public function addUsuario(\CECMED\SeguridadBundle\Entity\Usuario $usuario)
{
$usuario->addRolesUsuario($this);
$this->usuarios[] = $usuario;
return $this;
}
/**
* Remove usuario
*
* #param \CECMED\SeguridadBundle\Entity\Usuario $usuario
*/
public function removeUsuario(\CECMED\SeguridadBundle\Entity\Usuario $usuario)
{
$this->usuarios->removeElement($usuario);
}
/**
* Get usuarios
*
* #return \Doctrine\Common\Collections\Collection
*/
public function getUsuarios()
{
return $this->usuarios;
}
}
This is the Usuario Class
class Usuario implements AdvancedUserInterface

The Problem is that, when i generate schema with cli and the CRUD,The Usuario form works fine and it registers the role in database, but the Rol form when I insert a record does not register the user in database

Answer 1

What I have found with my foreign keys in Symfony is #ORM\JoinColumn was redundant. Doctrine can find the column from the #ORM\ManyToMany on its own. It's not clear in the docs in my opinion. I have not tried this with Many to Many relationships, but I have done quite a few Many to Ones. I had several issues until I just deleted all the JoinColumns. Try it out. Let me know how it goes.
