"go through ZPT" as in "redirect to another page"?

if so, you should override nextURL:


    def nextURL(self):
        return "whatever.html"
	    


Or, if "go though some block of code" means pre-processing the data you
got, you could do something like:


    def handle_edit_action_failure(self, action, data, errors):
        self.status = 'There have been %d errors.' % len(errors)


    @form.action("Button Label", failure='handle_edit_action_failure')
    def handle_edit_action(self, action, data):

        ....preprocessing here...

        if form.applyChanges(self.context, self.form_fields, data):
            notify(ObjectModifiedEvent(self.context))

            ....postprocessing here...

            self.status = 'Object has been updated'
        else:
            self.status = 'Nothing happened'
