Problem accessing paperclip file attributes in a callback (observer)

I'm having trouble accessing paperclip file attributes in an after_destroy callback on my attachment model. I can't seem to access the paperclip-managed attributes but I can access non-paperclip attributes. Here's an example:

class AttachmentObserver < ActiveRecord::Observer   def after_destroy(attachment)     attachment.logger.info "Deleted #{attachment.user.username} :: # {attachment.name}"   end end

The log message will say "Deleted Jsmith :: ". No attachment name though. Thanks for any help.

Here's a gist if you need it.
