Question

This is my Categorias model: http://pastebin.com/Wk5iw3Hf
and
this is my Proyectos model: http://pastebin.com/LDTpZ3Cy

One Category has many proyects.

In my repository, I´m trying to join this models, like this:

public function findMistareas() {
        $em = $this->getEntityManager();
        $consulta = $em->createQuery('SELECT c, p FROM GestionBundle:Categorias c JOIN c.proyectos p ');
        return $consulta->getResult();
}

but I´m getting this error:

Notice: Undefined index: Categorias in /Users/gitek/www/ges/vendor/doctrine/lib/Doctrine/ORM/Query/SqlWalker.php line 747

any help or clue? Maybe the problem is on the Model? but I can not see where.

Answer 1

/**
 * @ORM\ManyToOne(targetEntity="Categorias",inversedBy="proyectos")
 * @ORM\JoinColumn(name="categoria_id", referencedColumnName="id")
 */
private $categoria;

/**
 * @ORM\OneToMany(targetEntity="Hitos", mappedBy="Proyectos")
 * @ORM\OrderBy({"orden" = "ASC"})
 */
private $hitos;

‘SELECT p, h FROM GestionBundle:Proyectos p JOIN p.hitos h ‘

Your question is about categories but your query uses hitos? The mappedBy and inversedBy are case sensitive so probably need mappedBy=”proyectos” instead of mappedBy=”Proyectos”
