I am trying to understand how it works in the context of twisted.web and
Resources, but I always get an exception on the portal object
Here is the core code:
passwords = {"admin":"password"}
users = {"admin":"Administrator"}
realm = TestRealm(users)
p = portal.Portal(TestRealm(users),(PasswordDictChecker(passwords),))
credentialFactory = BasicCredentialFactory("CorePost")
resource = HTTPAuthSessionWrapper(portal, [credentialFactory])
print "Running..."
factory = Site(resource)
reactor.listenTCP(8084, factory)
reactor.run()
Error:

Attached the full file.
Not sure I understand what I am doing right here. The app starts up fine,
but throws the error on any request.
Also, how do I hook up actual Resources?
Do I do it do the HttpAuthSessionWrapper? It is an IResources, but
complains that it does not have a putChild() on it?
Should my TestRealm extend a Resource and I add my child Resource there?
Sorry for all the questions, but the docs don't really cover the A-Z
scenario of getting a running twisted.web app with Http auth... :-(
