My first Djangy project will be an application called
rightscalefeed. It will pull down a user's RightScale event feed. Ideally, I'd like to transform the feed into a WebSocket, suitable for continuous updates, perhaps for display in a data centre or network operations centre.
I may have bitten off more than I can chew, as I'm not sure Django (or Djangy's environment) has WebSocket support yet, but we'll see...
First, I need Djangy:
# sudo easy_install djangy
I need a work environment for the project. Djangy uses git for releases, so:
# mkdir -p Projects/djangy/rightscalefeed # cd Projects/djangy/rightscalefeed # git init .
Next, I get started creating the Djangy application:
# djangy create Please enter your application name: rightscalefeed Enter your email address: firstname.lastname@example.org Please enter your password: Using /home/david/.ssh/id_rsa.pub as your public key... Application created. Now you can run 'git push djangy master'.
That's the Djangy side of things, but before I push the project I need to take care of the Django side of things (ie, write some code).
# django-admin.py startproject rightscalefeed # cd rightscalefeed # django-admin.py startapp feed2ws
rightscalefeed/urls.py I have:
from django.conf.urls.defaults import * urlpatterns = patterns('', (r'^$', 'feed2ws.views.index') )
rightscalefeed/feed2ws/views.py I have:
from django.http import HttpResponse def index(request): return HttpResponse('testing')
I intend to use
feedparser, so I have added it to
Django South feedparser
Now to commit everything, push it to Djangy, and test:

Now I can test the project by visiting http://rightscalefeed.djangy.com in my browser:
Awesome! It worked.
I haven't done anything interesting with RightScale feeds yet, but I've shown how easy it can be to deploy a simple Django project to Djangy.
