Django-pagination breaks my order_by -

in html-template load list of objects , i'm trying combine django-pagination (from docs) , order_by method.

i tried put ordering-links loads href="/mylist/?order_by=somefield

it works on first page. order seems break when i'm clicking "next page". what's problem here?

"next page" link loads href="mylist/?page={{ results.next_page_number }}

view:

    def mylist(request):          order_by = request.get.get('order_by', 'somedefault')            myobjects_list = mymodel.objects.filter(user=request.user).order_by(order_by)         paginator = paginator(myobjects_list, 5)          page = request.get.get('page')         try:             results = paginator.page(page)         except pagenotaninteger:             results = paginator.page(1)         except emptypage:             results = paginator.page(paginator.num_pages)          context = {'results ': results }         return render_to_response('mylist.html', context, context_instance=requestcontext(request)) 

in view:

context = {'results ': results, 'order_by': order_by} 

in template:

href="mylist/?page={{ results.next_page_number }}&order_by={{ order_by }}"
