Get data in twig function

Is it bad practice to get data from db in twig function or I should pass it to view in controller?

My function is some kind of interface widget that is used on all pages of site admin section. Then on data change I will have to make changes in all actions. But when I get data directly in extension class our teamlead tells that it's bad MVC.

Your team leader is right. What you can do is create an action specific to render that widget. I.e create a custom widget, let's say you want to show the number of current active users:

class WidgetController extends Controller
{
    public function usersCountWidgetAction()
    {
        return $this->render('widget/usersCount.html.twig', array(
            "usersCount" => $this->getUsersCount();
        ));
    }

    public function getUsersCount() 
    {
        // call the manager and get the result
    }
}

Now in all your other twigs you can use 

{{ render(controller('AppBundle:Widget:usersCountWidget')) }}

It would be best if you pass it to a view from a controller.
