     4NOTE: All credit for this code goes to Crast in irc.freenode.net:#django...
     5
     6This uses SimpleXMLRPCDispatcher which is part of the standard Python lib in 2.4 (And possibly earlier versions).
     7
     8
     9In discussing ways of handling XML-RPC for Django, I realised I really needed a way to do it without patching Django's code.  Crast in #django came up with a great solution, which I have modified and tweaked a bit.
     10
     11I've included it here.  Feel free to fiddle with it and make it your own ... All this code is '''post-mr'''
     12
     13Any crappy & garbage code is completely mine; I'm still learning Python so bear with me.  The hacks I added for self-documentation output are just that; any improvements to them would probably be a good thing.
     14
     15First, setup your urls.py to map an XML-RPC service:
     16
     17
     18{{{
     19#!python
     20urlpatterns = patterns('',
     21    # XML-RPC
     22     (r'^xml_rpc_srv/', 'yourproject.yourapp.xmlrpc.rpc_handler'),
     23)
     24}}}
     25
     26
     27Then, in the appropriate place, create a file called xmlrpc.py
     28
     29
     30{{{
     31#!python
     32# Patchless XMLRPC Service for Django
     33# Kind of hacky, and stolen from Crast on irc.freenode.net:#django
     34# Self documents as well, so if you call it from outside of an XML-RPC Client
     35# it tells you about itself and its methods
     36#
     37# Brendan W. McAdams <brendan.mcadams@thewintergrp.com>
     38
     39# SimpleXMLRPCDispatcher lets us register xml-rpc calls w/o
     40# running a full XMLRPC Server.  It's up to us to dispatch data
     41
     42from SimpleXMLRPCServer import SimpleXMLRPCDispatcher
     43from django.http import HttpResponse
     44
     45# Create a Dispatcher; this handles the calls and translates info to function maps
     46#dispatcher = SimpleXMLRPCDispatcher() # Python 2.4
     47dispatcher = SimpleXMLRPCDispatcher(allow_none=False, encoding=None) # Python 2.5
     48
     49 
     50
     51def rpc_handler(request):
     52        """
     53        the actual handler:

     56        If post data is defined, it assumes it's XML-RPC and tries to process as such
     57        Empty post assumes you're viewing from a browser and tells you about the service.
     58        """
     59
     60        response = HttpResponse()
     61        if len(request.POST):
     62                response.write(dispatcher._marshaled_dispatch(request.raw_post_data))
     63        else:
     64                response.write("<b>This is an XML-RPC Service.</b><br>")
     65                response.write("You need to invoke it using an XML-RPC Client!<br>")
     66                response.write("The following methods are available:<ul>")
     67                methods = dispatcher.system_listMethods()
     68
     69                for method in methods:
     70                        # right now, my version of SimpleXMLRPCDispatcher always
     71                        # returns "signatures not supported"... :(
     72                        # but, in an ideal world it will tell users what args are expected
     73                        sig = dispatcher.system_methodSignature(method)
     74
     75                        # this just reads your docblock, so fill it in!
     76                        help =  dispatcher.system_methodHelp(method)
     77
     78                        response.write("<li><b>%s</b>: [%s] %s" % (method, sig, help))
     79
     80                response.write("</ul>")
     81                response.write('<a href="http://www.djangoproject.com/"> <img src="http://media.djangoproject.com/img/badges/djangomade124x25_grey.gif" border="0" alt="Made with Django." title="Made with Django."></a>')
     82
     83        response['Content-length'] = str(len(response.content))
     84        return response
     85
     86def multiply(a, b):
     87        """
     88        Multiplication is fun!
     89        Takes two arguments, which are multiplied together.

     92        return a*b
     93
     94# you have to manually register all functions that are xml-rpc-able with the dispatcher
     95# the dispatcher then maps the args down.
     96# The first argument is the actual method, the second is what to call it from the XML-RPC side...
     97dispatcher.register_function(multiply, 'multiply')
     98}}}
     99
     100That's it!
     101
     102You can pretty much write a standard python function in there, just be sure to register it with the dispatcher when you're done. 
     103
     104Here's a quick and dirty client example for testing:
     105
     106{{{
     107#!python
     108import sys
     109import xmlrpclib
     110rpc_srv = xmlrpclib.ServerProxy("http://localhost:8000/xml_rpc_srv/")
     111result = rpc_srv.multiply( int(sys.argv[1]), int(sys.argv[2]))
     112print "%d * %d = %d" % (sys.argv[1], sys.argv[2], result)
     113}}}
     114
     115Based on experience, I do recommend that you use Dictionaries for your args rather than long args, but I think that's personal preference (It allows named arguments, eliminates 'out of order' argument issues and it makes the code more self-documenting).
     116
     117Have fun!
