Symfony2 - Twig render controller and return array response
Question
Note : What I'm doing here is embedding controllers <--- see that link for a similar (official) example.
I want to call a controller from a twig template, and have that controller return an array that I can then use throughout the rest of my template.
I can do this with individual variables:
Twig
{% set testVar = render(controller('AppBundle:Test:index')) %}
Controller
class TestController extends Controller
{
public function testAction()
{
return new Response('OH HAI');
}
}
However, the following throws an exception: ("The Response content must be a string or object implementing __toString(), "array" given.") with the same twig file .
public function testAction()
{
return new Response(array('test' => 1, 'foo' => 'bar'));
}
This throws the above exception . How can I accomplish that which I seek without creating a dummy, useless extra template for the controller to render ?

The standard way to achieve what you want looks something like that.
Lets assume that you have your regular action. Eg.
class TestController extends Controller
{
public function testAction()
{
return $this->render('AppBundle:Test:index.html.twig');
}
}
And the template:
<html>
<body>
{% block sidebar %}
{{ controller('AppBundle:Test:sidebar') }}
{% endblock %}
{% block content %}
Hello world
{% endblock %}
</body>
</html>
Next you need create some action for the sidebar. Note that in this way you avoid put any logic into your view layer.
class BaseController extends Controller
{
public function sidebarAction()
{
$status = $this->get('some.status.logic')->retrieveStatus();
return $this->render('AppBundle:Base:sidebar.html.twig', array(
'status' => $status,
));
}
}
And your Base/sidebar.html.twig :
<div class="sidebar">
{{ status.showStatusInfo() }}
</div>
And that's all. You're not breaking MVP in that way, because you still don't have any logic in your view layer (the logic for the sidebar is in BaseController ).
