you may run into some trouble here constructing that query
in urls.py.
but really the view that you're composing here is pretty
simple without
generic views:

# views.py
def myview(request, year):
    return render_to_response('foo.html',
        { 'list': Event.objects.filter(date__year=year) })

this is probably another really simple view.  you can use
HttpResponseRedirect - or if you really want to end up using
a generic
view remember that you can call them within your own views
also.

# views.py
from django.views.generic.simple import redirect_to
def myview(request):
    # something
    return redirect_to(url=mycalculatedurl)

by the way here's a great txt by james bennett about doing
this kind of
wrapping:
