Hi, The first form saves fine but the second still dosn't. I can't seem to pass the poll object to the save method of the form properly.
Since i'm using nonrel once i've passed the poll object I can append the comment using something like poll.comments.append(comment) but I just don't seem to be able to get it going. I've re-written the form quite a few times without any luck and have looked at a few similar examples but can't quite piece it together. Any chance you could show me how its done?
