Bundle to add View Model capabilities to Symfony2

This bundle is not receiving any more support.




In your project root:

composer require aequasi/view-model-bundle ~4.0.0

In your app/AppKernel.php

public function registerBundles()
    $bundles = array(
        // ...
        new Aequasi\Bundle\ViewModelBundle\AequasiViewModelBundle(),
    // ...


To make a view model, create a new class that implements the ViewModelInterface. There are some other classes in that namespace that make it easy to make your own view model. I heavily suggest extending the AbstractViewModel. There are also two classes in that namespace that extend the abstract class:

  • HtmlViewModel - Sets a content type of text/html and doesnt do anything fancy to build the view
  • JsonViewModel - Sets a content type of application/json and doesnt do anything fancy to build the view



namespace Acme\DemoBundle\View\Index;

use Aequasi\Bundle\ViewModelBundle\View\Model\HtmlViewModel;

class IndexViewModel extends HtmlViewModel
  protected $template = 'AcmeDemoBundle:Index:index.html.twig';

  public function buildView($data)
    // Do some stuff with data, and then return what you want in the view
    return $data; // Does this by default in the ViewModel

You don't have to follow the same namespace structure, but it allows for a cleaner structure. This view model would be the view model for the IndexController's indexAction.

To Use the View Model

Use the @ViewModel Annotation in your action OR you can use the @ViewModelFactory Annotation:

namespace Acme\DemoBundle\Controller;

use Aequasi\Bundle\ViewModelBundle\Annotation\ViewModel;
use Aequasi\Bundle\ViewModelBundle\Service\ViewModelService;
use Aequasi\Bundle\ViewModelBundle\Controller\ViewModelControllerInterface;

class IndexController

   * @var ViewModelService
  private $view;

   * @ViewModel("Acme\DemoBundle\View\Model\Index\IndexViewModel")
   * OR
   * @ViewModel("")
   * @ViewModelFactory("", {"argumentOne", "argumentTwo"}) // You can also use a class name. The arguments are for you to decide what view model to use
  public function indexAction()
    $this->view = $this->container->get('aequasi.view_model.service.view');
    $this->getView()->add('someParameter', 'someValue');
    return $this->getView()->render(/*$templatName, $response*/);
    // You can also not return anything and it will create the response for you
    // It will also let you return an array that gets set as your view parameters
    return array('someParameter', 'someValue');
  public function setView(ViewModelService $service)
    $this->view = $service;
  public function getView()
    return $this->view;
A ViewModelFactory must implement ViewModelFactoryInterface and the create method must return a ViewModelInterface.
