I'd recommend using the Browser class of python mechanize:
http://wwwsearch.sourceforge.net/mechanize/
Should make most operations a lot easier, plus you can check for links
etc, then just "click" on them which is rather handy.
I'm using it to monitor a few sites (not, unfortunately, written in
django), and it is rather nice being able to just click round the place
and get data out again when needed. Mechanize + BeautifulSoup is
a very nice combination indeed.
Thanks,
