What I would like to do is something like this:
class testObj(object):
_rules = list()
def evalRules(self):
for r in _rules:
r()
def rule(func):
if not func in func.__class__._rules:
func.__class__._rules.append(func)
print testis._rules
return func
@rule
def arule(self):
print a
Of course it doesn't work. Is there a way to make it work? What I am
trying to do is make a collection of validation rules that can be
iterated and capture raised exceptions to be returned at the end of
eval rules.
I am trying to replace somethng that looks like this:
class testObj(object):
def _init__(self):
self._rules = list((self.arule,
self.anotherrule))
def evalRules(self):
for r in self._rules:
r()
It would be too easy to add a rule twice or forget to add the rule to
the list in a subclass. I thought that using a decorator would make it
obvious.
Thanks!
