I'm very new to Symfony2 and I need to be able to test the current route in TWIG so I can display sub-menus in a template that's rendered like:
{% render "CPAdminBundle:Messages:sidebarMenu" %}
{% render "CPAdminBundle:Readings:sidebarMenu" %}
Within the sidebar templates I tried using the following but it throws an error:
path(app.request.attributes.get('_route'))
What's the correct way of doing what I'm trying to accomplish?
The check you want to do doesn't belong to a view. Views should only take care of displaying, not doing any kind of logic.
Do the check in your controller and store it in a variable, pass this variable to your views, and the check the value of this variable in there.
If you want to do this on every action, give the kernel.controller event a look.
If you want to do it in the view anyway, simply compare app.request.attributes.get('_route') to the route you want. I don't understand why you put in path().
{% if app.request.attributes.get('_route') == 'my_route' %}
{% endif %}
$this->getRequest()->attributes->get('_route') in the controller?kernel.controller event, it might be what you need: symfony.com/doc/current/book/internals.html. Use it to check the route before each action. ;)
