I've been running into an increasing need for JS push notifications and have played with a few ways of doing it. Recently ran across Pusher API. They use a combo of HTML5 websockets & flash fallbacks. Much easier than Comet, etc.

But their python library didn't support presence. Here's everything you need to make presence work in Django, including an updated library.

My JS


var pusher = new Pusher('MY_PUBLIC_KEY');
Pusher.channel_auth_endpoint = '/api/pusher/auth/'
var channel = pusher.subscribe('presence-meeting-1')

an easy way to get django to send emails direct to stdout ( and avoid connection refused errors )

in settings.py:

and at a shell:

I am frequently running ./manage.py runserver SOME_IP:8000 , so I can run django dev on my local IP address, so it can be accessed by other computers on the network for testing. Here's a shell script to automate the steps it takes to do that:


#!/bin/bash

# virtualenv
source bin/activate

# get the local IP
IP=`ifconfig | grep 'inet addr:'| grep -v '127.0.0.1' | cut -d: -f2 | awk '{ print $1}'`;

# write the IP for use in settings module
echo "IP='$IP'" > local_settings_ip.py

# launch window in firefox ( will need to refresh )
firefox http://$IP:8000

It's easy to run multiple versions of django for python development. Let's say you already have an existing django project in a directory called "chat", but it needs a different django version than the one installed globally on your machine.


# get dependency package
sudo apt-get install python-virtualenv
# set up a new virtual environment for the "chat" directory
virtualenv --no-site-packages chat
cd chat
# create a requirements.txt file that will list the python modules you need, eg
nano requirements.txt
# use pip to install the packages
