How to make bookmarks based on session and cookies in Django?

Question

Django

Good day, I am new to Django and have not come across this before, the bottom line is that I do not have a personal account and authorization in the project, but I need the bookmark functionality.
There is such a code, please help me to make it work for session.

class Addbookmark(View):
    def post(self, request, pk,):
        child = Child.objects.get(id=pk)
        new_bookmark = BookmarksModel.objects.create(child=child)
        return redirect('/bookmarks/all-bookmarks/')


class BookmarksListView(ListView):
    model = BookmarksModel
    context_object_name = 'bookmarks'
    template_name = 'bookmarks/bookmarks.html'

class Addbookmark(View):
    def post(self, request, pk):
        child = Child.objects.get(id=pk)
        new_bookmark = BookmarksModel.objects.create(child=child)
        session_bookmarks = request.session.get("bookmarks_id", [])
        session_bookmarks.append(new_bookmark.id)
        request.session['bookmarks_id'] = session_bookmarks
        return redirect('/bookmarks/all-bookmarks/')
    

class BookmarksListView(ListView):
    model = BookmarksModel
    context_object_name = 'bookmarks'
    template_name = 'bookmarks/bookmarks.html'
    
    def get_queryset(self):
        return self.model.objects.filter(id__in=self.request.session.get("bookmarks_id", []))
