And what about something like this:
Field('image_filename', readable=False, writable=False, compute = lambda
row: request.post_vars.image.filename + next_id())
def next_id():
last_row = db().select(db.table.id).last()
last_id = int(last_row[`table.id`])
return last_id + 1
This was written from my cel phone and dont test it but hope that helps ;-)
