Symfony: how to assign data to a template in an inheritating controller-action?

I have TheParentController and the inheritating TheChildController, which should assign $moreData to the template, but the render() method should be called in TheParentController.

Is there any function/service for this case? I expect anything like

$this->get('templating')->assignDataForTemplate('moreData', $moreData);

class TheParentController 
{
    public function myAction($param1) {
        return $this->render('template.html.twig', array(
            'someData' => $someData
        ));
    }

}

-

class TheChildController 
{
    public function myAction($param1) {
        // !
        // Is there any function like "assignDataForTemplate"?
        $this->get('templating')->assignDataForTemplate('moreData', $moreData);
        // /!
        return parent::myAction($param1);
    }
}

I would like to avoid something like 

// ...
public function myAction($param1, $moreData = null) {
    return $this->render('template.html.twig', array(
            'someData' => $someData,
            'moreData' => $moreData
        ));
    }
}

You could try something like this, so that the parent is unaware of the child.

<?php    
class TheParentController {

    public function myAction () {
        $data = $this->getMyActionData();
        return $this->render('template', $data);
    }

    protected function getMyActionData () {
        return [
             'someDefault' => 5
        ];
    }
}

class TheChildController extends TheParentController {

    // If using annotation based routing override myAction
    // with call to parent function and new @Route tag in doc block

    protected function getMyActionData () {
        $parentData = parent::getMyActionData();
        return array_merge($parentData, [
            'childData' => 11  
        ]); 
    }
}

As far as I'm aware, there is no such way to do this currently. If you go through the sources, you'll see that calling $templating->render() is actually calling TwigEngine->render().That calls Twig_Template->render() which outputs the template to the client.

I fully understand why you might be using HMVC but I believe this approach might be overcomplicating things for you. If you have common code between controllers - just create a static class which can be called directly. Afterwards move your common logic/code there and call it whenever you need it.

Otherwise, you might need to stick with the code you're trying to avoid (or similar workaround) for now.
