In that case, this part of your view won't work:
{{for i in newD:}}
.......processing statements.......
{{pass}}
{{cPickle.dump(newD, open( "my_pkcl.p", "wb" ) )}}
Anything done in the web2py template language has to happen on the server
(before sending the page to the browser), not in the client. cPickle.dump
cannot be called from the browser -- that is strictly a server-side
operation. Anything that happens on the client side has to be done via
Javascript (and/or a standard form submission).

This sounds fine. It's not clear you need to store the data in the session
at all. It sounds like you can just load the data in the view, let the user
make and submit changes, and then simply update the db with those changes.
