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.

I'm not sure if this is what you're looking for, but I had a similar problem giving a thumbnail the foreign key of its parent. Try this in the model that's using attachment_fu: before_thumbnail_saved do |record, thumbnail| thumbnail.foo = record.foo end
