This is the sixth part of the Twisted tutorial :doc:`Twisted from Scratch, or The Evolution of Finger <index>` .
In this part, we demonstrate adding a web frontend using
simple :py:class:`twisted.web.resource.Resource`
objects: UserStatusTree , which will
produce a listing of all users at the base URL (/ ) of our
site; UserStatus , which gives the status
of each user at the location /username ;
and UserStatusXR , which exposes an XMLRPC
interface to getUser
and getUsers functions at the
URL /RPC2 .
In this example we construct HTML segments manually. If the web interface was less trivial, we would want to use more sophisticated web templating and design our system so that HTML rendering and logic were clearly separated.
