I'm building a class hierarchy that needs to keep as a class variable a reference to a (non-member) function, so that different subclasses can use different generator functions. But it seems Python is treating the function as a member function because the reference to it is in class scope....
Here's a simple case of what I'm trying (in the real code, fn is a function that returns a database connection relevant to that subclass): > def foo(): > print "foo called" > > class S(object): > fn = foo > > def bar(cls): > cls.fn() > bar = classmethod(bar) > > def foo2(): > print "foo2 called" > > class D(S): > fn = foo2 > > D.bar() [I'm on python 2.3.4 so no @classmethod decorator! ] When I run this: > Traceback (most recent call last): > File "t_o.py", line 19, in ? > D.bar() > File "t_o.py", line 10, in bar > cls.fn() > TypeError: unbound method foo2() must be called with D instance as first > argument (got nothing instead) This shows it is trying to do what I expect (call foo2()) but somehow the type is all wrong. I've tried playing with staticmethod() but I can't quite get it all worked out... -- http://mail.python.org/mailman/listinfo/python-list
