Doctrine Association Mapping OneToMany Bidirectional do not work

Question

i use doctrine ORM for generate a association one-to-many bidirectional, but when i execute the orm:validation-scheme command, this shows me the mesaje below:

"C:\\xampp\\htdocs\\Gestor\\vendor\\bin>doctrine-module orm:validate-schema [Mapping] FAIL - The entity-class 'Empleados\\Entity\\TipoDocumento' mapping is i nvalid: * The association Empleados\\Entity\\TipoDocumento#empleados refers to the owning side field Empleados\\Entity\\Empleado#tipodocumento which does not exist.

[Database] FAIL - The database schema is not in sync with the current mapping fi le."

The code: Empleado class (many to one side)

<?php
namespace Empleados\Entity;

use Doctrine\Common\Collections\ArrayCollection as Collection;
use Empresas\Entity\Empresa;
use Empleados\Entity\TipoDocumento;
use Doctrine\ORM\Mapping as ORM;
use Documentos\Entity\Documentacion_Empleado;

/**
 * @ORM\Entity
 * @ORM\Table(name="empleado")
 * 
 */

 class Empleado
 {
     /**
      * @ORM\Id
      * @ORM\GeneratedValue(strategy="AUTO")
      * @ORM\Column(type="integer")
      */
     private $id;

     /**
      * @ORM\Column(type="string",length=30,nullable=false,unique=true)
      */
     private $nro_documento;

    /*
     * @ORM\ManyToOne(targetEntity="Empleados\Entity\TipoDocumento",inversedBy="empleados")
     * @ORM\JoinColumn(name="tipodocumento_id", referencedColumnName="id")
     */
    private $tipodocumento;

 //...

 }

The TipoDocumento class (one to many side):

<?php
// yes, the class are in the same namespace "Empleados"
namespace Empleados\Entity;

use Doctrine\Common\Collections\ArrayCollection;
use Doctrine\ORM\Mapping as ORM;
use Empleados\Entity\Empleado;

/**
 * @ORM\Entity
 * @ORM\Table(name="tipo_documento")
 */

class TipoDocumento
{

    /**
     * @ORM\Id
     * @ORM\GeneratedValue(strategy="AUTO")
     * @ORM\Column(type="integer")
     */
    private $id;

    /**
     * @ORM\OneToMany(targetEntity="Empleados\Entity\Empleado", mappedBy="tipodocumento"))
     */
    private $empleados;

 //.....
    public function __construct()
    {
        $this->empleados = new ArrayCollection();
    }

 }

I'm based on the Doctrine documentation example in http://docs.doctrine-project.org/projects/doctrine-orm/en/latest/reference/association-mapping.html

Answer 1

In class TipoDocumento , private $empleados; should be private $empleado; .

Edit Sorry that's right, I was looking at the wrong place in the documentation.

The Many-to-one has the plural there. It also contains something like:

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

I can't tell if your class contains this function.

Answer 2

jmarkmurphy thanks for your help. The problem was in the camelcase of the "TipoDocumento" class, for some reason Doctrine does not like the camelcase ... What I did was rename the class to Tipo_documento and with that change everything started to work fine.
