How do I add an instance method to a class using a metaclass (yes I do need to use a metaclass)? The following kind of works, but the func_name will still be "foo":
def bar(self):
print "bar"
class MetaFoo(type):
def __new__(cls, name, bases, dict):
dict["foobar"] = bar
return type(name, bases, dict)
class Foo(object):
__metaclass__ = MetaFoo
>>> f = Foo()
>>> f.foobar()
bar
>>> f.foobar.func_name
'bar'
My problem is that some library code actually uses the func_name and later fails to find the 'bar' method of the Foo instance. I could do:
dict["foobar"] = types.FunctionType(bar.func_code, {}, "foobar")
There is also types.MethodType, but I need an instance that does'nt exist yet to use that. Am I missing someting here?
