I've been converting some of my code to the new Django 1.3 class-based views recently, and I must say that overall, it's been quite a frustration. I see the merits of class based views. It has resulted in some shorter code in certain places, and helped avoid some duplication (that I previously avoided equally well with functional views).

Anyway, that aside, there's one thing I found impossible to find any reference to online, and that is how to set an instance on a model form through class-based views. The best solution (that I can see) seems to be to override the get_form_kwargs function in your View class, like this:

    def get_form_kwargs(self):
        kwargs = super(YourView, self).get_form_kwargs()
        kwargs['instance'] = self.request.user
        return kwargs

This will give the kwargs to the model form an 'instance' key, that contains the model that should prefill all the fields. It's a clean and short solution, but it might have helped had the documentation told me from the onset that there is no straight-forward variable or function for this goal. Or is there? If there is, please let us know in the comments.
