# Choose what kind of storage to use for this uploader:
# storage :file
# storage :s3
# Override the directory where uploaded files will be stored.
# This is a sensible default for uploaders that are meant to be mounted:

"gallery/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"

# Provide a default URL as a default if there hasn't been a file uploaded:
# def default_url
# "/images/fallback/" + [version_name, "default.png"].compact.join('_')
# end
# Process files as they are uploaded:
# process :scale => [200, 300]
#
# def scale(width, height)
# # do something

# version :thumb do
# process :scale => [50, 50]
# end

# Add a white list of extensions which are allowed to be uploaded.
