变量“沙龙”不存在 - （树枝错误） - 获取salon_id

Question

In my layout I would like to get the view of the salon_edit by the id salon. Here is the symfony2 error "Variable "salon" does not exist" at the lign 61 -> <a href="{{ path('salon_edit', { 'id':salon.id }) }}" class="link_pink">Mon compte salon</a>

Could you help me please ?

Here is the twig's portion with this lign

<ul class="nav navbar-nav navbar-right">
                        <li>
                            {% if is_granted('ROLE_SALON') %}
                                <a href="{{ path('salon_edit', { 'id':salon.id }) }}" class="link_pink">Mon compte salon</a>
                            {% elseif is_granted('ROLE_USER') %}
                                <a href=# class="link_pink">Mon compte</a>
                            {% endif %}
                        </li>
                    {% if is_granted("IS_AUTHENTICATED_REMEMBERED") %}
                        <li>
                            <a href="{{ path('fos_user_security_logout') }}" class="link_rouge">Se déconnecter</a>
                        </li>
                    {% else %}
                        <li>
                            <a class="link_pink" href="{{ path('user_inscription') }}">S'inscrire</a>
                        </li>
                    {% endif %}
                </ul>

Here is my function from saloncontroller

    /**
 * Displays a form to edit an existing salon entity.
 *
 * @Route("/{id}/edit", name="salon_edit")
 * @Method({"GET", "POST"})
 */
public function editAction(Request $request, Salon $salon)
{
    $deleteForm = $this->createDeleteForm($salon);
    $editForm = $this->createForm('SalonBundle\Form\SalonType', $salon);
    $editForm->handleRequest($request);

    if ($editForm->isSubmitted() && $editForm->isValid()) {
        $this->getDoctrine()->getManager()->flush();

        return $this->redirectToRoute('salon_edit', array('id' => $salon->getId()));
    }

    return $this->render('@Salon/salon/edit.html.twig', array(
        'salon' => $salon,
        'edit_form' => $editForm->createView(),
        'delete_form' => $deleteForm->createView(),
    ));
}

Answer 1

You're passing an array of salons called salons. If you wanna have access to have you have to go through a twig for a loop. So in your:

{% if is_granted('ROLE_SALON') %}
    <a href="{{ path('salon_edit', { 'id':salon.id }) }}" class="link_pink">Mon compte salon</a>
{% elseif is_granted('ROLE_USER') %}
    <a href=# class="link_pink">Mon compte</a>
{% endif %}

you have to modify to:

{% if is_granted('ROLE_SALON') %}
    {% for salon in salons %}
        <a href="{{ path('salon_edit', { 'id':salon.id }) }}" class="link_pink">Mon compte salon</a>
    {%endfor%}
{% elseif is_granted('ROLE_USER') %}
    <a href=# class="link_pink">Mon compte</a>
{% endif %}

EDIT 1: Can you provide the Request Attributes section's content in the profiler
