I didn't test it, but in your example above class deco seems to be a
decorator factory
(because __call__ is an instance method, not a class method, and
calling a class always returns a new instance of this class).
So you should probably call it like this:
class deco(object):
def __init__(self, func):
self.func = func
def __call__(self, *args, **kwargs):
return self.func(*args, **kwargs)
@deco()
def myaction(self):
return 'results'
As I said, I haven't tested it :-)
