This document discusses migrating from Symfony 1 to Symfony 2. It covers key differences like Symfony 2's use of the Dependency Injection Container and lack of sfContext. It provides examples of implementing models, controllers and views in Symfony 2. Recommended bundles for common Symfony 1 features are also mentioned, along with caching and the HTTP layer.

3. cosa non è Symfony 2

4. cosa non è Symfony 2

5. cosa è Symfony2

6. Dependency Injection Container

7. come funziona il DIC
<?php
$mailer = $this->get('mailer');

8. come funziona il DIC
<?php
$mailer = $this->get('mailer');
niente più sfContext!

9. come funziona il DIC
<?php
$mailer = $this->get('newsletter');
<?php
namespace AcmeMyBundle;
class Newsletter
{
protected $mailer;
public function __construct(Swift_Mailer $mailer)
{
$this->mailer = $mailer;
}
}

10. come funziona il DIC
<?php
namespace AcmeMyBundle;
use DoctrineORMEntityManager;
class Newsletter
{
protected $mailer, $em;
public function __construct(Swift_Mailer $mailer, EntityManager $em)
{
$this->mailer = $mailer;
$this->em = $em;
}
}

11. test

12. model

13. model
$ app/console doctrine:mapping:import AcmeMyBundle annotation
$ app/console doctrine:generate:entities AcmeMyBundle --no-backup

14. model
<?php
namespace AcmeMyBundleEntity;
use DoctrineORMMapping as ORM;
/**
* @ORMTable(name="category")
* @ORMEntity
*/
class Category
{
/**
* @ORMColumn(name="id", type="integer")
* @ORMId
* @ORMGeneratedValue(strategy="AUTO")
*/
private $id;
/**
* @ORMColumn(name="name", type="string", length=255)
*/
private $name;
}

15. alcuni bundle da aggiungere
stof/doctrine-extensions-bundle
friendsofsymfony/user-bundle
sonata-project/doctrine-orm-admin-bundle

16. alcuni bundle da aggiungere
stof/doctrine-extensions-bundle
(sf1: behaviours)
friendsofsymfony/user-bundle
(sf1: sfGuardPlugin)
sonata-project/doctrine-orm-admin-bundle
(sf1: admin generator)

17. controller
<?php
/**
* Lists all Category entities.
*
* @Route("/", name="category")
* @Template()
*/
public function indexAction()
{
$em = $this->getDoctrine()->getManager();
$entities = $em->getRepository('AcmeMyBundle:Category')->findAll();
return array(
'entities' => $entities,
);
}

18. controller
/**
* @Route("/{id}/show", name="category_show")
* @Template()
*/
public function showAction($id)
{
$em = $this->getDoctrine()->getManager();
$entity = $em->getRepository('AcmeMyBundle:Category')->find($id);
if (!$entity) {
throw $this->createNotFoundException('Unable to find Category entity.');
}
$deleteForm = $this->createDeleteForm($id);
return array(
'entity' => $entity,
'delete_form' => $deleteForm->createView(),
);
}

19. /**
* @Route("/create", name="category_create")
* @Method("POST")
controller
* @Template("AcmeMyBundle:Category:new.html.twig")
*/
public function createAction(Request $request)
{
$entity = new Category();
$form = $this->createForm(new CategoryType(), $entity);
$form->bind($request);
if ($form->isValid()) {
$em = $this->getDoctrine()->getManager();
$em->persist($entity);
$em->flush();
return $this->redirect($this->generateUrl('category_show', array('id' =>
$entity->getId())));
}
return array(
'entity' => $entity,
'form' => $form->createView(),
);
}

20. view
{% extends 'AcmeMyBundle::layout.html.twig' %}
{% block content %}
<h1>Category list</h1>
<table class="table table-striped table-hover table-bordered records_list">
<tbody>
{% for entity in paginator %}
<tr>
<td><a href="{{ path('category_show', { 'id': entity.id }) }}">{{ entity.id
}}</a></td>
<td>{{ entity.name }}</td>
<td class="btn-group">
{# ... #}
</td>
</tr>
{% endfor %}
</tbody>
</table>
{% endblock %}
