[RFC] Compatibility with Symfony Flex

[lemoinem]

Symfony FOSUserBundle versions: dev-master

Description of the problem including expected versus actual behavior: When trying to install FOSUB in a Symfony Flex project, the assets:install commands fails, which prevents the bundle from being installed (see log).

I'm not sure what the best solution would be here... As far as I could see, there are no current solutions for interactive configuration via Flex's bundle autoconfiguration system. However, most project rely on the doctrine ORM to store users, AFAIK.

Maybe a solution could be to provide a "dummy" driver that allows the default configuration to go through but prevents actually using the bundle until an actual driver has been configured? What do you think?

Steps to reproduce:

1. Start a Symfony project using Symfony Flex
2. composer require composer require friendsofsymfony/user-bundle

Provide logs (if relevant):

Steps required to be able to install FOSUserBundle in a Symfony Flex project:

• Install symfony/swiftmailer-bundle
• Add the following configuration file in etc/packages/foo.yaml:

framework:
    templating: { engines: [twig] }

fos_user:
    db_driver: orm
    firewall_name: main
    user_class: FOS\UserBundle\Model\User
    from_email: {address: "fosub@localhost", sender_name: FOSUB}
    use_flash_notifications: false

What I would recommend:

1. Provide a dummy Database driver (custom won't cut it as it doesn't work out-of-the-box)
2. Add symfony/swiftmailer-bundle as a required dependency
3. Add a Symfony Flex recipe providing a default configuration working out-of-the-box

What do you think? I'm ready to start opening PRs if you think this is the way to go!

I also had to enable the "session" service

Inside config/packages/framework.yaml

framework:
    session:
        handler_id: session.handler.native_file
        save_path: '%kernel.project_dir%/var/sessions/%kernel.environment%'
    templating:
      engines: ['twig']

and had to create config/packages/fos_user.yaml with:

fos_user:
  db_driver: orm
  firewall_name: main
  user_class: App\Entity\User
  from_email:
      address: "[email protected]"
      sender_name: "Sender Name"

[allemas]

As we can find here, we have to define the mailer service.

On freshly installed SF3.3 with Flex i had to set:

fos_user:
    db_driver: orm # other valid values are 'mongodb' and 'couchdb'
    firewall_name: main
    user_class: App\Entity\User
    from_email:
        address: '%env(MAILER_USER_ADDRESS)%'
        sender_name: '%env(MAILER_USER_NAME)%'
    service:
        mailer: 'fos_user.mailer.noop'
        # mailer: 'fos_user.mailer.twig_swift' # Works as well

worked for me, I hope this will help you.

I don't want to add SwiftmailerBundle as a required dependency, as this would hurt anyone not using it (and Swiftmailer is not the only option to send emails, with the rise of tools like Sendgrid or Mandrill doing all the heavy work). This must stay an optional dependency.

However, I do want to improve the setup with Flex. I just haven't had time to do it yet.

[allucardster]

Thanks @allemas It works for me

Hello,

I am struggling to get this package working with Flex. Finding this issue I assume that it is currently not possible. As such I wont proceed yet until there is some new documentation for this that takes into consideration the new config directory and the service autowiring.

Is there any update?

[jsampedro77]

@tip2tail I am using this following @allemas indications. You just have to create the configuration yaml before doing the composer require.

If using swiftmailer then you have to require it before fos-user.

[covex-nn]

May be fos_user.mailer.twig_swift should be a default fosub mailer service instead of fos_user.mailer.default? Then templating service won't be used any more by default.

See FOS\UserBundle\DependencyInjection\Configuration::addServiceSection

@stof The dependency is optional, but the FOS mailer seems to require a Swift_Mailer instance according to PHPDoc:

/**
 * Mailer constructor.
 *
 * @param \Swift_Mailer         $mailer
 * @param UrlGeneratorInterface $router
 * @param EngineInterface       $templating
 * @param array                 $parameters
 */
public function __construct($mailer, UrlGeneratorInterface  $router, EngineInterface $templating, array $parameters)
{
    $this->mailer = $mailer;
    $this->router = $router;
    $this->templating = $templating;
    $this->parameters = $parameters;
}

Forget my last comment, I read the code too fast.

Any news on this ?
