django CreateView doesn't show on ListView until rerun the server

2782 views python

I am trying to create an object using CreateView

class PlayerCreate(CreateView):

    template_name = 'form.html'
    model = Player
    form_class = PlayerForm
    header = "Player"

    def get_context_data(self):
        context = super(PlayerCreate, self).get_context_data()
        context['header'] = self.header
        return context

    def form_valid(self, form):
        valid = super(PlayerCreate, self).form_valid(form)
        if not self.request.user.is_staff or not self.request.user.is_superuser:
            return HttpResponse("Only authorized user can edit or create")
        return valid

It works. However, when I jump into the ListView Part, I need to rerun

python runserver

to make the new item show on the list.

I want to make it work without rerun the server. Thanks!

Below is my ListView code

class PlayerList(ListView):

    template_name = "list.html"
    header = 'Player'
    queryset = Player.objects.all().order_by("-timestamp")

    def get_context_data(self):
        context = super(PlayerList, self).get_context_data()
        context['header'] = self.header
        return context

    def get_queryset(self):
        query = self.request.GET.get("q")
        if query:
            self.queryset = self.queryset.filter(
            return self.queryset
            return self.queryset

In this case, you should only use get_query_set() not queryset in your ListView. queryset only runs the very first time your server starts while get_query_set() works every time a request is made, that's why you only see the new element in the ListView when you rerun python runserver.
