Symfony2 - get main request's current route in twig partial/subrequest - php

Question

In Twig partial rendered by separate controller, I want to check if current main route equals to compared route, so I can mark list item as active.
How can I do that? Trying to get current route in BarController like:
$route = $request->get('_route');
returns null.
Uri is also not what I'm looking for, as calling below code in bar's twig:
app.request.uri
returns route similar to: localhost/_fragment?path=path_to_bar_route
Full example
Main Controller:
FooController extends Controller{
public function fooAction(){}
}
fooAction twig:
...some stuff...
{{ render(controller('FooBundle:Bar:bar')) }}
...some stuff...
Bar controller:
BarController extends Controller{
public function barAction(){}
}
barAction twig:
<ul>
<li class="{{ (item1route == currentroute) ? 'active' : ''}}">
Item 1
</li>
<li class="{{ (item2route == currentroute) ? 'active' : ''}}">
Item 2
</li>
<li class="{{ (item3route == currentroute) ? 'active' : ''}}">
Item 3
</li>
</ul>

pabgaran's solution should work. However, the original problem occurs probably because of the request_stack.

Since you are in a subrequest, you should be able to get top-level (master) Request and get _route. Something like this:
public function barAction(Request $request) {
$stack = $this->get('request_stack');
$masterRequest = $stack->getMasterRequest();
$currentRoute = $masterRequest->get('_route');
...
return $this->render('Template', array('current_route' => $currentRoute );
}
Haven't run this but it should work...

I think that the best solution in your case is past the current main route in the render:
{{ render(controller('FooBundle:Bar:bar', {'current_route' : app.request.uri})) }}
Next, return it in the response:
public function barAction(Request $request) {
...
return $this->render('Template', array('current_route' => $request->query->get('current_route'));
}
And in your template compares with the received value.
Otherwise, maybe is better to use a include instead a render, if you don't need extra logic for the partial.

in twig you can send request object from main controller to sub-controller as parameter:
{{ render(controller('FooBundle:Bar:bar', {'request' : app.request})) }}
in sub-controller:
BarController extends Controller{
public function barAction(Request $request){
// here you can use request object as regular
$country = $request->attributes->get('route_country');
}
}
