Symfony2 array of forms?

Is it possible to create and render and array of forms I know about collections but they don't really fit in my idea?

What I want is something like this

Controller

$data=$em->findAll();
$Forms=$this->createForm(new SomeType,$data);

return $this->render(someView,array("Forms"=>$Forms->createView()));

Twig

  {% for Form in Forms %}
  {{ form(Form)}}
  {% endfor %}

The action :

$forms = [];

foreach ($articles as $article) {
    $forms[$article->getId()] = $this->get('form.factory')->createNamed(
        'article_'.$article->getId(), // unique form name
        ArticleType::class,
        $article
    );
    $forms[$article->getId()]->handleRequest($request);

    if ($forms[$article->getId()]->isValid()) {
        // do what you want with $forms[$article->getId()]->getData()
        // ...
    }
}

And a better way to render :

return $this->render('some_view.html.twig', [
    'forms' => array_map(function ($form) {
        return $form->createView();
    }, $forms),
]);

Symfony3:

$datas = $em->findAll();

foreach ($datas as $key=>$data)
{
   $form_name = "form_".$key;
   $form = $this->get('form.factory')->createNamed( 
      $form_name, 
      SomeType::class, 
      $data
   );
   $views[] = $form->createView();
}
return $this->render(someView, ["forms" => $views]);

Just create your forms in array:

$data = $em->findAll();
for ($i = 0; $i < $n; $i++) {
    $forms[] = $this->container
        ->get('form.factory')
        ->createNamedBuilder('form_'.$i, new SomeType, $data)
        ->getForm()
        ->createView();
}

return $this->render(someView, array("forms" => $forms));

UPDATED

As mentioned by edlouth you can create each form named separately. I updated my code.

Create the forms in an array, but give each one a unique name. I've changed it to formbuilder which might not be ideal for you but hopefully something similar will work. I'm also not certain about putting in new SomeType rather than 'form', see http://api.symfony.com/2.4/Symfony/Component/Form/FormFactory.html#method_createNamedBuilder.

$data = $em->findAll();
for ($i = 0; $i < $n; $i++) {

    $forms[] = $this->container
        ->get('form.factory')
        ->createNamedBuilder('form_'.$i, new SomeType, $data)
        ->getForm()
        ->createView();
}

return $this->render(someView, array("forms" => $forms));
