Take a look at this:

http://docs.djangoproject.com/en/1.0/ref/models/instances/#how-django-knows-to-update-vs-insert

- after first ns.save() 'ns' receives primary key (id), which in turn
causes any subsequent
ns.save() to UPDATE previously created row. I'm not sure why
'force_insert' is an unexpected
argument, but it doesn't make sense anyway to use it.
You can try ns.id = None; ns.save() instead.
