No, but isn't the key element doing the db query? It would be something
similar to this from the Simple Wiki example:
def search():
"""an ajax wiki search page"""
return dict(form=FORM(INPUT(_id='keyword',_name='keyword',
_onkeyup="ajax('callback', ['keyword'], 'target');")),
target_div=DIV(_id='target'))
I think that when Massimo was last presenting in SoCal, he did a simple
tagging demonstration, so you might look to see if he has that in one of
the video examples, but now that you've done the star ratings, I think
you've got the tools you need.
