Question

I’m using a form with 2 classes (“ArticleType” and “ArticleHandler“) for my class Article.

I would like to send the id of the article I’ve just created, but I can’t manage to show this id parameter in the view :

In the controller, I send my article’s id :

$handler = new ArticleHandler($form, $request, $em);
if ($handler->process()){
    return $this->redirect($this->generateUrl('myproject_show', array('id' => $article->getId())) );
}

and in the view, I’ve got an error with :

{% block body %}
    <p>the id :</p>
    {{ id }}
{% endblock %}

or entity.id (as in the CRUD) :

Variable “id” does not exist…
Variable “entity.id” does not exist…

Do you know how to fix this?

Thanks

EDIT :
here’s my method :

public function addAction()
{
    $article = new Article();
    $form = $this->createForm(new ArticleType(), $article);
    $request = $this->getRequest();
    $em = $this->getDoctrine()->getEntityManager();

    $handler = new ArticleHandler($form, $request, $em);
    if ($handler->process()){
        return $this->redirect($this->generateUrl('myproject_show', array('id' => $article->getId())) );
    }

    return $this->render('ProjBlogBundle:Blog:add.html.twig', array(
        'form' => $form->createView(),
    ));
}

and here’s the view :

{% extends "ProjBlogBundle::layout.html.twig" %}

{% block title %}
  the title - {{ parent() }}
{% endblock %}

{% block sousbody %}
    <p>here's the article i've just created :</p>
    {{ id }}
{% endblock %}

EDIT N°2 :

myproject_show:
    pattern:  /show/{id}
    defaults: { _controller: ProjBlogBundle:Blog:show, id:5 }

To use a variable in a template you need to pass it when you render your template:

//ProjBlogBundle:Blog:show
public function showAction($id)
{
    return $this->render('ProjBlogBundle:Blog:show.html.twig', array(
        'id' => $id
    ));
}

$this->redirect($this->generateUrl('myproject_show', array('id' => $article->getId())) ); returns only HTTP 302-response without rendering a template, and the browser is redirected to the generated url…
