Paperclip Duplicate Checker
|Version||1.0 (Apr 20, 2012)|
|License||Released under the MIT license.|
This class extends Paperclip, adding a feature that forgoes uploading a replacement for an existing attachment file if the replacement is identical to the existing file.
In order for this to work, your model _must_have an
column, since MD5 fingerprints are used for comparison. To use, simply follow
class MyModel < ActiveRecord::Base include CheckForDuplicateAttachedFile :note check_for_duplicate_attached_file :note end
Et voila! You save on bandwidth costs if your code re-uploads a lot of the same files.
