  # Choose what kind of storage to use for this uploader:
  storage :file

  # Override the directory where uploaded files will be stored.
  # This is a sensible default for uploaders that are meant to be mounted:
  def store_dir

  # Add a white list of extensions which are allowed to be uploaded.
  # For images you might use something like this:

    %w(jpg jpeg png pdf)
