This is an excellent thread. I came here with the same questions as Marc. My revelation seems to be that forms are for data, and saving is control. And these two have separate concerns/goals. Such that fields shouldn't be in forms for the sole reason to make control of the form function properly.
So you can put the id in you forms with a hidden, or in the action="" attribute, or using some sort of JavaScript, or whatever. So, I understand that the key should be controlled outside the scope of the Django form support. But, I wonder if something like {{ form_set.management_form }} for formsets could be used here. Perhaps something like {{form.indentifier_key}} on a template in the form could by default write out a hidden field of the pk of the instance. It would just be shorthand for putting the instance in the context, and typing <input type="hidden" name="pk" value="{{instance.id}}"..../> But, it could make your view work like this, so you don't have to query up the model instance yourself. f = your_modelform(request.POST) f.instance # would be the read from the DB and set for you.
