Challenge #1 of 1

Your colleague installed KnpTimeBundle into your app to use |ago Twig filter in templates. You also want to leverage this "ago" format but inside a controller. In the bundle's docs you found that you can do it by calling formatDiff() method on the time.datetime_formatter service.

How could you inject that service into your controller if the output of bin/console debug:autowiring command is the next:

Autowirable Types
=================

 The following classes & interfaces can be used as type-hints when autowiring:

 App\Kernel (kernel)

 EntityManager interface
 Doctrine\ORM\EntityManagerInterface (doctrine.orm.default_entity_manager)
 Doctrine\ORM\EntityManagerInterface $defaultEntityManager (doctrine.orm.default_entity_manager)

 Knp\Bundle\TimeBundle\DateTimeFormatter (time.datetime_formatter)

 PaginatorInterface
 Knp\Component\Pager\PaginatorInterface (knp_paginator)

 Describes a logger instance.
 Psr\Log\LoggerInterface (monolog.logger)

 Interface for mailers able to send emails synchronous and/or asynchronous.
 Symfony\Component\Mailer\MailerInterface (mailer.mailer)

 Symfony\Component\Serializer\SerializerInterface (debug.serializer)

 Stores the Twig configuration and renders templates.
 Twig\Environment (twig)

 ...

 725 more concrete services would be displayed when adding the "--all" option.

use Knp\Bundle\TimeBundle\DateTimeFormatter;
use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\Routing\Annotation\Route;

class UserController extends AbstractController
{
    #[Route('/newsletter', name: 'app_newsletter')]
    public function newsletter(/* @time.datetime_formatter */ $dateTimeFormatter)
    {
    }
}

use Knp\Bundle\TimeBundle\DateTimeFormatter;
use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\Routing\Annotation\Route;

class UserController extends AbstractController
{
    #[Route('/newsletter', name: 'app_newsletter')]
    public function newsletter(DateTimeFormatter $dtFormatter)
    {
    }
}

You can't autowire this service in the controller's methods.

use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\Routing\Annotation\Route;

class UserController extends AbstractController
{
    #[Route('/newsletter', name: 'app_newsletter')]
    public function newsletter(DateTimeFormatter $dateTimeFormatter)
    {
    }
}
