In your particular case, one solution you might consider is
Javascript. Have the partial output some inline javascript which
generates a random number and inputs it into the desired place (hidden
form field, etc). I have used this approach successfully to get a
random image to show up on an otherwise cached page.
Another more general solution to this problem might be to split your
view into 2 partials-- one for the stuff that will be cached
(_show.php), and the other existing one for the comment box
(_addcomment.php). Simply have the template pass along the needed info
to the _show.php partial, and turn on caching for that partial. This
means that the view will still need to be rendered (minimal overhead),
but the partial will be cached, so no need for the DB queries. The
downside to this approach is just in the messiness of adding an extra
layer of view code. But it should still be much faster than running
with the cache turned off entirely.
