passing template render result to another method

Question

i'm trying to assign $this->render() result to a method (this method renders google map's infoWindow/baloon).

I'm using method like this to create this infoWindow:

$infoWindow->setContent(<here goes the template>);

but passing it like this:

$infoWindow->setContent($this->render('WmapFrontBundle:Place:infoWindow.html.twig'));

don't work at all. What's the proper way to assign template to a variable or pass it's content to a method ?

Answer 1

Use renderView(), it returns the rendered template only.

render() returns a Response object (with the rendered template, headers, etc).
