form_valid() overload

The Django documentation describes how to bind uploaded files when using function-based views. There’s no easy equivalent I could find on how to do the same for generic, class based views like CreateView. The right way to do it is to override the form_valid() method on the view:

def form_valid(self, form):
    file = self.request.FILES["file"]
    self.object = form.save(commit=False)
    self.object.file = file
    self.object.save()
    return HttpResponseRedirect(self.get_success_url())
