I would recommend you put this in a separate decorator like this:
@turbogears.expose(...)
@exception_flash({Exception: 'generic msg'})
def mymethod(self):
... etc ...
It may be cool to have an exception_flash decorator built in to
turbogears. Though I really wish cherrypy had an event system or better
filtering system so we didn't have to push all of this functionality
into decorators.
