I have a model using attachment_fu (via has_attachment) and I'm creating thumbnails for the attached images. I have an extra field 'foo' that I'm validating on create with validates_presence_of :foo.
One problem arises when I upload an image:
The 'foo' is not propogating down to the thumbnails. What should I put in my model to grab the parent's (via parent_id) 'foo' if no foo is provided?
Thanks in advance.
