You code is not very clear,
you could make your changes to your view as below:
views
def inventory(request,id):
if request.method =='POST':
staff=Inventory.objects.get(id=id)
form=InventoryForm(request.POST,instance=staff)
if form.is_valid():
form.save()
return render_to_response('display_successful_message.html')
else:
staff=Inventory.objects.get(id=id)
form=InventoryForm(instance=staff)
return render_to_response('inventory.html')
Hope this helps.
Cheers,
Sum
