What is the right way to iterate over nested array in Twig - php

Question

I have this function on a repository:
public function getSolicitudes($usuario_id)
{
$qb = $this->getEntityManager()->createQueryBuilder();
$qb
->select('su.id, su.fecha_creacion, tt.nombre AS tipo_tramite, tr.nombre AS tipo_registro, es.nombre AS estado_solicitud')
->from("ComunBundle:SolicitudUsuario", "su")
->where('su.usuario = :usuario_id')
->join('su.tipo_tramite', 'tt', \Doctrine\ORM\Query\Expr\Join::INNER_JOIN)
->join('su.tipo_registro', 'tr', \Doctrine\ORM\Query\Expr\Join::INNER_JOIN)
->join('su.estado_solicitud', 'es', \Doctrine\ORM\Query\Expr\Join::INNER_JOIN)
->orderBy('su.fecha_creacion', 'DESC')
->setParameter('usuario_id', $usuario_id);
return $qb->getQuery()->getResult();
}
In Twig template I have this:
{{ entities|ladybug_dump }}
And the output is something like image show:
I'm trying to iterate over the result in Twig template as follow:
{% for solicitud in entities %}
<tr>
<td></td>
<td>{{ solicitud.tramite }}</td>
<td>{{ solicitud.id }}</td>
<td>{{ solicitud.solicitud }}</td>
<td>{{ solicitud.estado }}</td>
<td>{{ solicitud.fecha }}</td>
<td></td>
</tr>
{% endfor %}
But I got this error:
Key "tramite" for array with keys "id, fecha_creacion, tipo_tramite,
tipo_registro, estado_solicitud" does not exist in
/var/www/html/src/RPNIBundle/Resources/views/Listado/index.html.twig
at line 25
What I'm missing here?

Answer 1

It's obvious, you're using the wrong key, as the exception suggests:
Key "tramite" for array with keys "id, fecha_creacion, tipo_tramite, tipo_registro, estado_solicitud" does not exist in /var/www/html/src/RPNIBundle/Resources/views/Listado/index.html.twig at line 25
Your object has a tipo_tramite key, not tramite. You should change the output statements.
