Hi Nerdture, I'm not a core team member, but I believe that there's currently no documented way of accessing a file before the record has been saved (more precisely, before the after_commit callback). There is, however, `attachment_changes` hash, which keeps track of what changes are made. You should be able to access the attachment with `record.attachment_changes[' pv_file']`. Keep in mind that this is undocumented internal api, so it could change in the future.
