渲染控制器动作时通过参数更改模板？

Question

I got a simple CRUD-controller with a indexAction() to list all items. Now I want render this action within another template and change the .

{{ render(controller("MyBundle:MyEntity:index")) }}

Is there a predefined parameter to change the template? Sure its easy to pass this value, but I don't want reinvent the wheel.

There is no native parameter to change the template but you can pass an argument to the action defined by the render method ...

{ render(controller('MyBundle:MyEntity:index', { 'template': 'MyBundle:ControllerName:foo.html.twig' })) }}

... and use it inside your controller action to decide which template to render.

class MyEntityController
{
     public function indexAction($template = null)
     {
         // ... some code here

         $template = $template ? $template : 'MyBundle:ControllerName:index.html.twig';

         return $this->render(
             $template,
             array(
               'variable' => $variable,
             )
         );
     }
