hoping for a quick code review of a few simple class-based generic views

I am working on a simple "to do list" app in django (two models: List and Item). Trying to learn and make use of class-based generic views. I have the following three display views working, but am requesting a quick code review to see if there's anything I can do to improve my usage/understanding of django's ListView and DetailView before I move on to creating, updating and deleting. Thanks in advance for any advice.

# class-based generic views for my lists, a list's items, and item detail...

class MyListsView(ListView):

    """Display the current user's Lists"""

    template_name = 'cmv_app/my_lists.html'

    context_object_name = 'my_lists'

    @method_decorator(login_required)

    def dispatch(self, *args, **kwargs):

        return super(MyListsView, self).dispatch(*args, **kwargs)

    def get_queryset(self):

        return List.objects.filter(user=self.request.user).order_by('-last_modified')

class ListItemsView(ListView):

    """Display a list's items"""

    template_name = 'cmv_app/list_items.html'

    context_object_name = 'list_items'

    @method_decorator(login_required)

    def dispatch(self, request, *args, **kwargs):

        self.list = get_object_or_404(List, pk=kwargs['list_id'])

        request = list_valid_for_user(request, self.list) # security check

        return super(ListItemsView, self).dispatch(request, *args, **kwargs)

    def get_queryset(self):

        return Item.objects.filter(list=self.list).order_by('-created_date')

    def get_context_data(self, **kwargs):

        context = super(ListItemsView, self).get_context_data(**kwargs)

        context['list'] = self.list

        return context

class ItemDetailView(DetailView):

    """Display detail for one list item"""

    template_name = 'cmv_app/item_detail.html'

    @method_decorator(login_required)

    def dispatch(self, request, *args, **kwargs):

        self.list = get_object_or_404(List, pk=kwargs['list_id'])

        self.item = get_object_or_404(Item, pk=kwargs['item_id'])

        request = list_valid_for_user(request, self.list)  # security check

        request = item_valid_for_list(request, self.item, self.list)  # security check

        return super(ItemDetailView, self).dispatch(request, *args, **kwargs)

    def get_object(self):

        return self.item

    def get_context_data(self, **kwargs):

        context = super(ItemDetailView, self).get_context_data(**kwargs)

        context['list'] = self.list

        return context
