# Mix this module into an Uploader to make it mimic Paperclip's storage paths
|
|
# This will make your Uploader use the same default storage path as paperclip
|
|
# does. If you need to override it, you can override the +paperclip_path+ method
|
|
# and provide a Paperclip style path:
|
|
#
|
|
# class MyUploader < CarrierWave::Uploader::Base
|
|
# include CarrierWave::Compatibility::Paperclip
|
|
#
|
|
# def paperclip_path
|
|
# ":rails_root/public/uploads/:id/:attachment/:style_:basename.:extension"
|
|
