Challenge 1 / 1

You have an ImageUploader service. And you need to inject a correct path where to store the images. Your boss said the images should be stored in the public/media/uploads/ folder according to the project root directory, and you need to inject the full path to that dir as the 1st argument of that service. The bin/console debug:container --parameters output is:

 Symfony Container Parameters
 ============================

 --------------------------------
  Parameter                Value
 --------------------------------
  fragment.path            /_fragment
  image_uploads_dir        media/uploads
  kernel.logs_dir          /Users/sfcasts/www/starshop/var/log
  kernel.project_dir       /Users/sfcasts/www/starshop
  kernel.secret            %env(APP_SECRET)%

How can you inject that path into the service?

# config/services.yaml
services:
    App\Service\ImageUploader:
        arguments:
            - "public/%image_uploads_dir%"

# config/services.yaml
services:
    App\Service\ImageUploader:
        arguments:
            - "%kernel.project_dir%public%image_uploads_dir%"

# config/services.yaml
services:
    App\Service\ImageUploader:
        arguments:
            - "%kernel.project_dir%/public/%image_uploads_dir%"

# config/services.yaml
services:
    App\Service\ImageUploader:
        arguments:
            - "kernel.project_dir%/public/%image_uploads_dir"
