title: Django - request.session not being saved
body: <p>I have a pretty simply utility function that gets an open web order if their is a session key called 'orderId', and will create one if there is no session key, and the parameter 'createIfNotFound' is equal to true in the function. Stepping through it with my debugger I can see that the piece of code that sets the session key after an order has been created does get hit with no exceptions, but when I check the Http request object' session field, it does not have that attribute ? </p>
  
  <p>Utility</p>
  
  <pre><code>def get_open_web_order(request, createIfNotFound=False):
      # Check for orderId in session
      order_id = request.session.get('orderId')
      web_order = None
  
      if None != order_id:
          try:
              web_order = WebOrder.objects.get(id=order_id, status='O')
              logging.info('Found open web order')
          except WebOrder.DoesNotExist:
              logging.info('Web order not found')
  
      if (None == web_order) and (createIfNotFound == True):
          logging.info('Creating new web order')
  
          web_order = WebOrder()
          web_order.status = 'O'
  
          web_order.save()
          request.session['orderId'] = web_order.id
  
          # Assign logged in user and default billing and shipping
          if request.user.is_authenticated() and hasattr(request.user, 'customer'):
              customer = request.user.customer
              web_order.customer = customer
              web_order.set_defaults_from_customer()
              web_order.save()
  
      return web_order
