Another option that doesn't need subclassing is to pass a callable for
the options. Because cherrypy.request is thread-local and has all the
parameters bound to it, you can then build the options-list based on that.
def calc_options():
return model.Thing.select(model.Thing.q.attribute ==
cherrypy.request.params['the_param'])
