Sorry, I missed an "if" in the code that makes it clearer.
class MyCrazyController(TGController):
def __init__(self, is_shouting=False):
self.is_shouting = is_shouting
self.default_engine = self.index.decoration.engine['text/
html']
def shouting(self, *args, **kw):
if self.is_shouting:
current_engine = self.index.decoration.engine['text/html']
self.index.decoration.engine['text/html'] =
['genshi','shouting_template'].extend(current_engine[:2])
self.default_engine = current_engine
def default_voice(self, *args, **kw):
self.index.decoration.engine['text/html'] =
self.default_engine
@before_render(shouting)
@after_render(default_voice)
@expose('genshi:regular_template')
def index(self, *args, **kw):
return dict(john_wayne="you got that right, kid")
