I'm trying to call SetName on an object to prevent me from ever having to call
it explictly again on that object. Best explained by example.
def setname(cls):
'''this is the proposed generator to call SetName on the object'''
try:
cls.SetName(cls.__name__)
finally:
yield cls
class Trial:
'''class to demonstrate with'''
def SetName(self, name):
print 1, 1
@setname
class Test(Trial):
'''i want SetName to be called by using setname as a decorator'''
def __init__(self):
print 'Yay! or Invalid.'
if __name__ == '__main__':
test = Test()
How can i fix this?
I am not sure what exactly you want to achieve, but I see 2 problems here:
1. Your setname operates on a class, but your SetName() is an instance
function.
2. I don't really understand the try...finally yield stuff. As others
already said, you probably just want to return. I don't see what a
generator would be useful for here...
def setname(cls):
'''this is the proposed generator to call SetName on the object'''
try:
cls.SetName(cls.__name__)
finally:
return cls
and
class Trial(object):
'''class to demonstrate with'''
@classmethod
def SetName(cls, name):
print 1, 1
should solve your problems.
