Django ModelAdmin.save_model() -vs- ModelAdmin.save_formset()

Question

I want to ensure that a user editing a particular model is saved in that models updated_by (FK User) field.

I'm using mostly ModelForms (not necessarily the built in Admin), and wondering:

In what cases would I need to override ModelAdmin.save_model() or ModelAdmin.save_formset()?

Or, is that doing it wrong? If it's just the models' save() method that needs to be overridden, is there a proper way to access the request object there?

This was previously answer by Daniel Roseman over here.

If you want something that will work both in the admin and elsewhere, you should use a custom modelform.
