There is no need for an ID in the form because you are probably POSTing to the same URL with ID there. Check the following code: def view(request, pk): instance = get_object_or_404(MyModel, pk=pk) if request.method == "POST": form = MyModelForm(request.POST, request.FILES, instance=instance) if form.is_valid(): form.save() else: form = MyModelForm(instance=instance) return render_to_response("mytemplate.html", { "form": form, }, context_instance=RequestContext(request)) -- Brian Rosner http://oebfare.com --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Django users" group.
