That all looks fine. It should work.

That suggests state.name is the empty string, possibly.

Hmm ... are you sure "state" is really a State object? Because if it
was, say, a string, then state.get_absolute_url would return an empty
string to the template (as the get_absolute_url attribute or method
doesn't exist).
You can test out what should be happening by opening up an interactive
prompt (python manage.py shell) and testing it out manually. Something
like this:
>>> st = State.objects.get(pk=1)
...
>>> st.name
u"fred"
>>> st.get_absolute_url()
"/slug/foo/"
You could also simplify your template or view and make it work with just
a single state object first (instead of the list). Make sure that when
you pass in a hard-coded State instance, it displays something. Then
move onto dynamically working out which State instances to display.
