Python Decorators and inheritance
- by wheaties
Help a guy out. Can't seem to get a decorator to work with inheritance. Broke it down to the simplest little example in my scratch workspace. Still can't seem to get it working.
class bar(object):
def __init__(self):
self.val = 4
def setVal(self,x):
self.val = x
def decor(self, func):
def increment(self, x):
return func( self, x ) + self.val
return increment
class foo(bar):
def __init__(self):
bar.__init__(self)
@decor
def add(self, x):
return x
Oops, name "decor" is not defined.
Okay, how about @bar.decor? TypeError: unbound method "decor" must be called with a bar instance as first argument (got function instance instead)
Ok, how about @self.decor? Name "self" is not defined.
Ok, how about @foo.decor?! Name "foo" is not defined.
AaaaAAaAaaaarrrrgggg... What am I doing wrong?
