變量“ salon”不存在-（樹枝錯誤）-get salon_id

Question

在我的布局中，我想獲得id salon的salon_edit視圖。 這是在61行處出現symfony2錯誤“變量“ salon”不存在“-> <a href="{{ path('salon_edit', { 'id':salon.id }) }}" class="link_pink">Mon compte salon</a>

請問你能幫幫我嗎 ？

這是這枝木的樹枝部分

<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>

這是我發廊控制器的功能

    /**
 * 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

您正在通過一系列稱為沙龍的沙龍。 如果您想訪問，則必須通過樹枝進行循環。 因此，在您的：

{% 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 %}

您必須修改為：

{% 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 %}

編輯1：可以在探查器中提供“請求屬性”部分的內容嗎

Answer 2

如果您嘗試訪問父模板的變量，請嘗試此操作，也許可行

{％set salonParentVar =沙龍％}
