has_attached_file gets read when the class file is first read. It then sets up the various paperclip methods that do there stuff. When it does that, 'instance' is a new/blank record.
What you have below will work (if memory serves me right) if you save the record, reload it, and then reprocess it. Something along those lines... it's been awhile since I ran into this. -philip On Oct 10, 2010, at 1:22 PM, Christian Fazzini wrote: > anyone??
