I read and used this http://www.zope.org/Members/Caseman/Dynamic_Hotfix This works great for changing methods and stuff inside classes, but what about stuff that isn't inside the class? (Maybe more of a Python question rather than Zope) --- module.py ---------- def manage_addSomething(self,id): self._setObject(id,Something(id)) class Something(SimpleItem): def __init__(self,id): self.id = id del somemethod(self): return "hello" ---------------------------- This I can HotFix like this: ---- hotfix: __init__.py -------------- # import class from module import Something def myown(self):return "Hello!" Something.somemethod = myown -------------------------------------- But it is this that I can't get to work. Here I need help: ---- buggyhotfix: __init__.py -------------- # import function from module import manage_addSomething def myown(self,id): id = string.upper(id) self._setObject(id,Something(id)) module.manage_addSomething = myown -------------------------------------- it's the "module.manage_addSomething = myown" part that looks like the evil thing. Any hints? Cheers, Peter
