Symfony 2 - Delete Forms and CSRF Token

Question

I have a List of entries coming from a database. I would like to have a \"Delete-Button\" at the end of every row, so that the user won\'t have to first go to the edit/show page

The answer of @Lighthart led me to the correct answer:

In your controller generate an array of form views and had it over to the view:

public function indexAction()
{
    $em = $this->getDoctrine()->getManager();

    $entities = $em->getRepository('AppBundle:Entity')->findAll();

    $delete_forms = array_map(
        function ($element) {
            return $this->createDeleteForm($element->getId())->createView();
        }
        , $entities
    );

    return $this->render('AppBundle:Entity:index.html.twig', array(
        'entities' => $entities,
        'delete_forms' => $delete_forms
    ));
}

Now you have to access this in your view. Therefore you can use the form functions and the special loop variables:

{% extends '::base.html.twig' %}

{% block body %}
    {% for entity in entities %}
        {# Access the delete form for this entity using the loop index ... #}
        {% set delete_form = delete_forms[loop.index0] %}

        {# ... and display the form using the form tags. #}
        {{ form_start(delete_form) }}
            
        {{ form_end(delete_form) }}
    {% endfor %}
{% endblock %}

That's it.
