Rails - Aug 2010 - Paperclip - possible to modify file and load file content as string?

Wanted to see if anyone knows of a way - or the preferred way - to do these
three tasks with Paperclip:

1) Access the content of an uploaded file before save. I did find that the
following works before save, but is there a clearer way to do this:

self.uploaded_file.queued_for_write[:original].open.read

2) Access the content of a file after save while my AR model instance is
still alive and/or when I load a record and need the file content. i.e. do I
just need to manually read the file into my object from the Paperclip path,
or is there a direct method in Paperclip to do this?

3) (if #2 above is possible), is there a way I can modify the file content
and if so, does calling object.save on the Paperclip enabled object after a
change save the changes?

Paperclip seems to make everything easy but I can''t seem to find a
direct
way to do these tasks. Maybe it was not really designed for what I am trying
to do but is gets me pretty far along.

Thanks in advance,

David
