# 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:

# Process files as they are uploaded:
# process :scale => [200, 300]
#
# def scale(width, height)
# # do something
# end
# Create different versions of your uploaded files:
# version :thumb do
# process :scale => [50, 50]
# end
# Add a white list of extensions which are allowed to be uploaded.
# For images you might use something like this:
# def extension_white_list
# %w(jpg jpeg gif png)
# end
# Override the filename of the uploaded files:
# def filename
# model.filename.force_encoding("UTF-8")
