Who am I?

Why a talk on WTF?

why a talk on WTF?

symfony 1 was focused on
Rapid Application Development

the (old) times?

Symfony2 is focused on
Application Development

the shiny new thing

create-project symfony/framework-standard-edition ./foo 2.3.0

installation

php app/console cache:clear

cache/log permissions

cache all the things (in dev too)!

http://symfony.com/doc/current/book/templating.html

cache all the things (in dev too)!

config.yml:
twig:
cache:

false

user session in cache!

capifony?
idephix? :-P


config.yml:
framework:
session:
save_path: "%kernel.root_dir%/sessions/"

symfony2 needs a writable filesystem
symfony2 uses some restricted functions
you can warmup cache, but paths are absolute
the problem is not only limited to symfony (eg: assetic)

@ParamConverter

do you need everything?

/**
* @ParamConverter("post", class="SensioBlogBundle:Post")
*/
public function showAction(Post $post)
{
...
}


/**
*/
{
...
}
{
...
}


/**
*/
{
...
}
{
...
}
public function showAction(Post $post, Comment $comment)
{
...
}


/**
*/
{
...
}
{
...
}
public function showAction(Post $post, Comment $comment)
{
...
}

kill the magic?

public function showAction($post_id)
{
$post = $this->getRepository(‘Posts’)
->findOneById($post_id);
}

explicit vs implicit

use DoctrineDBALTypesType;
use DoctrineDBALPlatformsAbstractPlatform;

/**
* NewObject datatype
*/
class NewObjectType extends Type
{
public function convertToPHPValue($value, AbstractPlatform $platform)
{
$listeners = $platform -> getEventManager() -> getListeners('getContainer');

$listener = array_shift($listeners);
$container = $listener -> getContainer();

return $container -> get('service');
}
}

if u can it doesn’t mean you have to

class A
{
protected $first_service;
protected $second_service;
public function __construct(ContainerInterface $container)
{
$this->first_service = $container->get(‘firstService’);
$this->second_service = $container->get(‘secondService’);
}
}

passing around the DIC is bad

class A
{
protected $first_service;
protected $second_service;
public function __construct(FirstService $first, SecondService $second)
{
$this->first_service = $first;
$this->second_service = $second;
}
}

in services.yml:
services:
my.service:
arguments:
- "@first_service"
- "@second_service"
class: MyClassA

passing around the DIC is bad

configuration (FosUserBundle)...

configuration is just another way of
programming

configuration...

is there a way to create decoupled,
maintainable code?

configuration...

ddd, code first, ...

after all Symfony2 is just a
framework

Wrap up

framework != architecture

Wrap up

do you need that feature?

Wrap up

keep things decoupled

Wrap up

Thank you!
