this is the view code...

The lines starting with `venue_form.user` and `venue_form.slug` aren't doing what you intend. They aren't setting the value of the form's fields to anything - they are just setting arbitrary attributes on the form, which are ignored.

What you mean to do is this:

        venue_form = VenueForm(request.POST) 

        if venue_form.is_valid(): 
            venue = venue_form.save(commit=False) 

            venue.user = u 
            venue.slug = slugify(venue.name) 

            venue.save()

To make this work, you'll probably need to add the user and slug fields to the form's `exclude` tuple.

I don't know what this has to do with "chained FKs", though.
