Handles JSONRPC and XMLRPC requests easily with Django

Project description



RPC4Django has been tested on Mac OS, Linux and Windows.

Source Install Method

This is the preferred method for installing RPC4Django.

$> tar xvfz rpc4django-x.y.z.tar.gz
$> cd rpc4django-x.y.z
$> python install

Easy Install Method

$> easy_install rpc4django

Pip Install Method

$> pip install rpc4django

No Installation Method

This method installs RPC4Django only for one specific django project but does not require any special system access.

$> tar xvfz rpc4django-x.y.z.tar.gz
$> cd rpc4django-x.y.z


Usual Setup

  1. First, you need to add new url pattern to your root file. This file should be the one pointed to by ROOT_URLCONF in You can replace r'^RPC2$' with anything you like.

    urlpatterns = patterns('',
        # if installed via no install method
        #(r'^RPC2$', 'YOURPROJECT.rpc4django.views.serve_rpc_request'),
        # if installed via source or easy_install
        (r'^RPC2$', 'rpc4django.views.serve_rpc_request'),
  2. Second, add RPC4Django to the list of installed applications in your

        # if installed via no install
        # if installed via source or easy_install
  3. Lastly, you need to let RPC4Django know which methods to make available. This is done with the decorator @rpcmethod. RPC4Django recursively imports all the apps in INSTALLED_APPS and makes any methods importable via with the @rpcmethod decorator available as RPC methods. You can always write your RPC methods in another module and simply import it in

    # testapp/
    from rpc4django import rpcmethod
    # This imports another method to be made available as an RPC method
    # This method should also have the @rpcmethod decorator
    # from mymodule import myrpcmethod
    # The doc string supports reST if docutils is installed
    @rpcmethod(name='mynamespace.add', signature=['int', 'int', 'int'])
    def add(a, b):
        '''Adds two numbers together
        >>> add(1, 2)
        return a+b

    The decorator @rpcmethod accepts three optional parameters:

    • name - is the name under which the method will be made externally available. It defaults to the method’s real name.
    • signature - is the signature of the method and will be returned by calls to the XMLRPC introspection method system.methodSignature. It is of the form: [return_value, arg1, arg2, arg3, ...]. All of the types should be XMLRPC types (eg. struct, int, array, etc. – see the XMLRPC spec for details). Since python is relatively loosely typed, all types are set to object by default.
    • permission - the Django permission required to execute this method [new in 0.1.5]

Remotely Calling Methods


XMLRPC libraries exist in virtually every major programming language. The usage varies from library to library, but I’ll give a python example using the xmlrpclib standard library:

from xmlrpclib import ServerProxy
s = ServerProxy('http://localhost:8000')


JSONRPC is less mature than XMLRPC and libraries are not as common. However, one of the main benefits of JSONRPC is that it can be used more easily from Javascript or Actionscript since JSON is their native format. There is an older JSONRPC library for python on Here is an example using that library:

from jsonrpc import ServiceProxy
s = ServiceProxy('http://localhost:8000')

For an example of JSONRPC being used from Javascript running in a browser, please see the demo site.
