S3/Cloud Creates wrong public path when using separate thumbnail class

[mpetnuch]

If you have a separate thumbnail class the wrong public_filename is show when using S3/Cloud.

Examples:

photo = Photo.find(328)
=> #<Photo id: 328, parent_id: nil, size: 2078, width: 33, height: 48, content_type: "image/gif", filename: "Hollowbody_1.gif", thumbnail: nil, caption: nil, position: 43, picturable_id: 14, picturable_type: "Topic", created_at: "2010-07-30 15:05:02", updated_at: "2010-07-30 15:05:03">

File System:

photo.public_filename
=> "/photos/0000/0328/Hollowbody_1.gif"
photo.public_filename(:thumb)
=> "/thumbnails/0000/0328/Hollowbody_1_thumb.gif"

S3/Cloud:

photo.public_filename
=> "http://XXX.cloudfront.net/photos/328/Hollowbody_1.gif"
photo.public_filename(:thumb)
=> "http://XXX.cloudfront.net/photos/328/Hollowbody_1_thumb.gif"

Here is a patch that fixes it:

  1.7.2

[bacrossland]

If you're running this under ruby 1.9.2 you have to make an additional change to the s3_backend.rb because of the way ruby 1.9.2 handles arrays to string.

Your public_filename method needs to change to look like the following:

      def public_filename(*args)
           if args.empty?
              clean_args = nil
           else
              clean_args = args.join  
           end

          if attachment_options[:cloudfront]
             cloudfront_url(clean_args)
         else
             s3_url(clean_args)
         end
      end
