How to map and use a DB View from Doctrine2 - php

Question

I have a view on nomencladores schema called obtenerPaisesPorFabricanteProductoSolicitud. This is the content for the view:
SELECT
ps.id AS psid,
ps.nombre,
fps.id AS fpsid
FROM
(
(
nomencladores.pais ps
JOIN nomencladores.pais_fabricante_producto_solicitud pfps ON ((pfps.pais_id = ps.id))
)
JOIN negocio.fabricante_producto_solicitud fps ON (
(
pfps.fabricante_producto_solicitud_id = fps.id
)
)
);
I'm trying to map the view as follow:
use Doctrine\ORM\Mapping as ORM;
/**
* #ORM\Entity
* #ORM\Table(name="nomencladores.obtenerPaisesPorFabricanteProductoSolicitud", schema="nomencladores")
*/
class ObtenerPaisesPorFabricanteProductoSolicitud
{
/**
* #ORM\Id
* #ORM\Column(name="psid", type="integer", nullable=false, unique=true)
*/
protected $ps;
/**
* #ORM\Column(name="fpsid", type="integer")
*/
protected $fps;
/**
* #ORM\Column(name="nombre", type="string")
*/
protected $nombre;
public function getPs()
{
return $this->ps;
}
public function getFps()
{
return $this->fps;
}
public function getNombre()
{
return $this->nombre;
}
}
But any time I run this code on it:
$ent = $em->getRepository("AppBundle:ObtenerPaisesPorFabricanteProductoSolicitud")->findBy(
array(
"fps" => $entF->getId()
)
);
I got this result:
An exception occurred while executing 'SELECT t0.psid AS psid1,
t0.fpsid AS fpsid2, t0.nombre AS nombre3 FROM
nomencladores.obtenerPaisesPorFabricanteProductoSolicitud t0 WHERE
t0.fpsid = ?' with params [22]:
SQLSTATE[42P01]: Undefined table: 7 ERROR: relation "nomencladores.obtenerpaisesporfabricanteproductosolicitud" does not
exist LINE 1: ...d1, t0.fpsid AS fpsid2, t0.nombre AS nombre3 FROM
nomenclado...
If I remove the annotations then the error transform on this:
"Class
"AppBundle\Entity\ObtenerPaisesPorFabricanteProductoSolicitud"
is not a valid entity or mapped super class."
Why Doctrine2 or Symfony tries to execute the query instead go through the view? How I can execute the view from Symfony2/Doctrine2 side?
EDIT
As a side note I'm using PostgreSQL as DB and it haves several squemas, in this case I wrote the view at nomencladores schemas but I tried putting also in public schema and none works, apparently Doctrine doesn't find the view on the schema
