Django: How to return a raw response

You shouldn’t return the response from urlopen method directly. Instead your view should return an instance of django’s HttpResponse, where body and the headers should be set to those from the original response:

from django.http import HttpResponse
import urllib2

def my_view(request):
    request = urllib2.Request(url, formData, headers)
    response = urllib2.urlopen(request)

    # set the body
    r = HttpResponse(response.read())

    # set the headers
    for header in response.info().keys():
        r[header] = response.info()[header]

    return r

How to pull a random record using Django’s ORM?

Using order_by('?') will kill the db server on the second day in production. A better way is something like what is described in Getting a random row from a relational database.

from django.db.models.aggregates import Count
from random import randint

class PaintingManager(models.Manager):
    def random(self):
        count = self.aggregate(count=Count('id'))['count']
        random_index = randint(0, count - 1)
        return self.all()[random_index]
