It looks like one of the recent updates to attachment_fu has changed the way it names/stores files in the filesystem. I'm guessing it was this one:
* add default ID partitioning for attachments
Anyway, my files used to be stored in directories named after the PK. Now it seems that things have changed and files are stored with a new scheme.
So, anyone have any suggestions as to how I can migrate to the new storage setup? All the images in my app are broken.
