Sometimes parsing order is wrong, and files are not updated in the right sequence. This needs to be investigated. A complex example is below, but I have also seen similar issues in simpler cases.

from django.template import RequestContext
from django.shortcuts import render_to_response
from django.contrib.auth import (authenticate, login, logout)

from storageadmin.models import (Appliance, Setup, UpdateSubscription)
from django.shortcuts import redirect
from django.contrib import messages
from django.conf import settings
from rest_framework.renderers import JSONRenderer


def login_page(request):
    return render_to_response('login.html',
                              context_instance=RequestContext(request))
