XMPP integration for Django app made simple!

Attention!

This application is in early development stage. Every help or feedback is appreciated.

Features

  • ConverseJS web chat integration
  • Support for MUC auto join
  • Support for users query
  • Ejabberd Django authentication using ejabberd_auth management command
  • Single sign on functionality without storing user's credentials (requires using ejabberd_auth)
  • Set avatar using gravatar and vCard during first login

Installation

Install django-xmpp via pip:

pip install django-xmpp

Add xmpp and django_gravatar into INSTALLED_APPS:

INSTALLED_APPS = (
    ...
    'django_gravatar',
    'xmpp',
)

Setup most important variables:

XMPP_DOMAIN = 'example.com'
XMPP_BOSH_SERVICE_URL = 'https://xmpp.example.com:5280/http-bind'

Optionally setup ConverseJS to suit your needs:

XMPP_CONVERSEJS_SETTINGS = {
    'allow_contact_removal': False,
    'allow_contact_requests': True,
    'auto_subscribe': True,
    'allow_logout': False,
    'allow_muc': True,
    'allow_otr': False,
    'allow_registration': False,
    'message_carbons': True,
    'hide_muc_server': True,
    'use_vcards': True,
    'animate': True,
    'play_sounds': True,
    'xhr_user_search': True,
    'sounds_path': '%ssounds/' % STATIC_URL,
    'visible_toolbar_buttons': {
         'call': False,
         'clear': False,
         'emoticons': True,
         'toggle_participants': False,
    }
}

Include xmpp.urls in your urls.py:

urlpatterns = [
    ...
    url(r'^xmpp/', include("xmpp.urls")),
]

Use ConverseJS in your base template:

{% load xmpp_tags %}
{% conversejs_initialize %}

Ejabberd Django authentication

Create ejaberd_auth.sh file that will simply call ejabberd_auth management command. Adjust to suit your environment (eg. virtualenv):

#!/bin/bash
cd <path_to_your_django_project>
python manage.py ejabberd_auth $@

Edit ejabberd.yml and add external auth script, eg.:

host_config:
    "example.com":
        auth_method: external
        extauth_program: "/<path_to_your_project>/ejabberd_auth.sh"

Settings

These are all available settings you may use.

XMPP_BOSH_SERVICE_URL
URL for ConverseJS BOSH connection
XMPP_DOMAIN
Default XMPP domain
XMPP_DOMAIN_MUC
Domain for multi user chats (default converence.<XMPP_DOMAIN>)
XMPP_CONVERSEJS_AUTH
Authentication type for ConverseJS (prebind is not supported so login is the only option)
XMPP_CONVERSEJS_SETTINGS
dictionary of settings passed to converse.initialize. For more list of available options see Converse.js docs
XMPP_ENABLED
Enable or disable XMPP at all
XMPP_UPDATE_VCARD
Enable or disable vCard update
XMPP_UPDATE_VCARD_HOURS
Update vCard every n hours (default False)

A note on usernames

Jabber IDs are case-insensitive (so "MyUser@domain.com" and "myuser@domain.com" are the same account). By contrast, the username field in the default Django User model is case-sensitive (see this Django ticket). This means two separate "MyUser" and "myuser" accounts in Django will have the same JID on the XMPP server. The ejabberd_auth management command will not authenticate such users, and they will both see "Authentication failed" in Converse and other XMPP clients.

To avoid such conflicts, it is recommended to use a custom User model that enforces unique lowercase usernames with a RegexField. Other characters not allowed in a Jabber ID should be excluded as well. See this guide for details.
