I should add that you *can* be more creative, and construct each mapper
with a MapperExtension at the beginning which later can be "enabled" with
a "hello world" callable. i.e.
class MyExt(MapperExtension):
def __init__(self):
self.func = None
def after_insert(self, ...):
if self.func:
self.func()
extension = MyExt()
mapper(foo, bar, extension=extension)
mapper(foo2, bar2, extension=extension)
mapper(foo3, bar3, extension=extension)
... do stuff ...
def helloworld():
print "hello world"
extension.func = helloworld
... do stuff ...
