Overview

Youtube video hosting, easy place to share videos for You can find at www.youtube.com/ There are a few S3-specific options for has_attached_file:

  • youtube_credentials: Takes a path, a File, or a Hash. The path (or File) must point to a YAML file containing the login_name and login_password and youttube_username

and developer_key that you can got it from your account on Youtube.

You can 'environment-space' this just like you do to your
database.yml file, so different environments can use different accounts:
  development:
    login_name: dr-click...
    login_password: 123...
  production:
    login_name: dr-click...
    login_password: 123...
