Django: How to Retrieve Query String Parameters


3rd October 2010 in Coding Tags: django, programming, python

If you use Django you will surely know that its url routing is quite strict regarding the prettiness of its URLS.

An url that in a php application could be like:


With django would translate:


The nice thing is that this pretty django URLs don't cause significant overhead, at least not as by doing the same with Php, MySQL and Apache (example: Joomla).

So how to retrieve query string params with Django?

There are still cases in we need to handle query string parameters, like when dealing with external services that return a URL like:


Following this example, create the "callback" URL in your urlconf:


from django.conf.urls.defaults import *

# import your view to pass to the URL
from views import callback

urlpatterns = patterns('',
    url(r'^callback$', view=callback, name='callback'),
	# your other URLS

Then create the view that retrieves the parameters:


from django.template import Context, RequestContext
from django.shortcuts import render_to_response, get_object_or_404

# your other views

# callback
def callback(request):

    verification_code = request.GET.get('verification_code')
    userid = request.GET.get('userid')

    context = {
        'verification_code': verification_code,
        'userid': verification_url,

    return render_to_response('callback.html', context, context_instance=RequestContext(request))

And then create the template that shows the result. Be sure to put in one of your TEMPLATE_DIRS.

<!-- callback.html -->

verification_code: {{ verification_code }}<br />
verification_url: {{ userid }}

Very easy indeed and Django takes care of filtering the data to avoid XSS attacks or SQL Injection automatically for you! Isn't that nice?
