title: How do you set the property of a model instance while using generic view to create it?
body: <p>Let's say trying to use django.views.generic.create_update.create_object to allow the user to a blog entry instance.  On the Entry model, there is a required field for the user, that I don't want to show up as an editable field on the blog entry form.  So, I would include it into the EntryForm.Meta.exclude tuple.  </p>
  
  <p>Where should I set the value for the user property on the resulting model instance?  Would I have to stop using the create_object generic view and write my own?</p>
