Hello,
Before starting, let me show some sample codes so I can explain:
class A(object):
def __init__(self):
super(A, self).__init__()
x = type("X", (A, ), {})()
This works fine, but suppose I have several classes like A and I would
like to create a decorator to call super. First I tried this:
def init(func):
def _init(inst):
super(inst.__class__, inst).__init__()
func(inst)
return _init
class A(object):
@init
def __init__(self): pass
This works when I create a instance by doing A(), but I get
"RuntimeError: maximum recursion depth exceeded" when I create a new
type doing type("X", (A, ), {}) and then create an instance of it.
To "solve" this problem, I changed the init function to this then:
def init(func):
def _init(inst):
super(inst.__class__.__mro__[-2], inst).__init__()
func(inst)
return _init
It works if A is a direct subclass of object, if it is not I have to
adapt the index [-2].
So, is there a better way to do this ?
