Somewhere in the environ, there's the Routes stuff. You can use that
to figure out which action was executed. I usually just print out the
environ and start poking around. Once you know what action was
executed, get the actual method via "getattr(self, action_name)".
>From there, you can do "getattr(action_method, 'validation_handler',
None)". Make sense?
