You can always override the .save() method to check to see if the pk field is None, and refuse to save if it is not:

https://docs.djangoproject.com/en/1.4/topics/db/models/#overriding-predefined-model-methods

That being said, this kind of thing is *much* better done at the DB level, so that you can be certain that there are no other paths that allow data to be updated.
