something like this?
(don't now if you want the form from an instance or not, but assumed so, as
you are trying to change data, not?)
def comp(request, obj_id):
instance = get_object_or_404(Model, obj_id)
form = ItemForm(instance=instance)
if request.method=="POST":
form = ItemForm(request.POST, request.FILES, instance=instance)
if form.is_valid():
if form.price >= instance.price and form.pub_date <=
instance.pub_date:
item = form.save(commit=False)
item.seller = request.user
item.save()
form = ItemForm()
else:
pass
return render_to_response(
"add_item.html",
{"form": form},context_instance=RequestContext(request))
