Cómo saltear o ignorar los decoradores de pitón

Question

Hay una función envuelta por un decorador que devuelve el resultado de la función como HTML. Me gustaría llamar a esa función sin el envoltorio HTML del decorador. ¿Es eso posible?

Ejemplo:

class a: 
    @HTMLwrapper 
    def returnStuff(input): 
     return awesome_dict 

    def callStuff(): 
     # here I want to call returnStuff without the @HTMLwrapper, 
     # i just want the awesome dict. 

Answer 1

class a: 
    @HTMLwrapper 
    def return_stuff_as_html(self, input): 
     return self.return_stuff(input) 
    def return_stuff(self, input): 
     return awesome_dict 

me hicieron lo mismo a la espera de una respuesta y funciona muy bien para mí, pero todavía me gustaría saber si hay una mejor manera:) - olofom

Dado que en python las funciones y los métodos son objetos, y dado que un decorador devuelve un llamador, puede establecer un atributo en el método decorado que apunte a la metanfetamina original od, pero una llamada como my_object_instance.decorated_method.original_method() sería más fea y menos explícita.

Beautiful is better than ugly. 
Explicit is better than implicit. 
Simple is better than complex. 
Complex is better than complicated. 
Flat is better than nested. 
Sparse is better than dense. 
Readability counts. 
Special cases aren't special enough to break the rules. 
Although practicality beats purity. 
Errors should never pass silently. 
Unless explicitly silenced. 
In the face of ambiguity, refuse the temptation to guess. 
There should be one-- and preferably only one --obvious way to do it. 
Although that way may not be obvious at first unless you're Dutch. 
Now is better than never. 
Although never is often better than *right* now. 
If the implementation is hard to explain, it's a bad idea. 
If the implementation is easy to explain, it may be a good idea. 
Namespaces are one honking great idea -- let's do more of those! 

Answer 2

Claro:

class Example(object): 
    def _implementation(self): 
     return something_awesome() 

    returnStuff = HTMLwrapper(_implementation) 

    def callStuff(self): 
     do_something_with(self._implementation())

__author__ = 'Jakob' 

class OptionalDecoratorDecorator(object): 
    def __init__(self, decorator): 
     self.deco = decorator 

    def __call__(self, func): 
     self.deco = self.deco(func) 
     self.func = func 
     def wrapped(*args, **kwargs): 
      if kwargs.get("no_deco") is True: 
       return self.func() 
      else: 
       return self.deco() 
     return wrapped 

def spammer(func): 
    def wrapped(): 
     print "spam" 
     return func() 
    return wrapped 

@OptionalDecoratorDecorator(spammer) 
def test(): 
    print "foo" 

test() 
print "***" 
test(no_deco=True)
