No, it's a separate class. Put it wherever you like - it's often put
in a separate forms.py, but it just needs to be somewhere you can
import it.
BTW, I missed off a line - there should be
model=Poll
at the end, at the same indentation level as exclude.

That does make it tricky. You can pass the form in as a parameter via
the URL, but that won't help with the post-save customisation.
One possibility is to 'wrap' the generic view in a custom view. James
Bennett wrote a good blog post about this a couple of years ago:
