My first Djangy project (initial testing)

·3 mins

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: david@cloudartisan.com
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

In rightscalefeed/urls.py I have:

from django.conf.urls.defaults import *  
urlpatterns = patterns('',
    (r'^$', 'feed2ws.views.index')
)

In 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 djangy.eggs:

Django
South
feedparser

Now to commit everything, push it to Djangy, and test:

# git add .
# git commit -a -m 'Initial release'
[master fa7b52b] Initial release
    2 files changed, 10 insertions(+), 1 deletions(-)
# git push djangy master

Now I can test the project by visiting http://rightscalefeed.djangy.com in my browser:

Testing rightscalefeed.djangy.com

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.

Stay tuned to see if I’ve bitten off more than I can chew. Follow me on Twitter. It’s free!

Cheers!
