I got this error "KeyError at / ", how to fix it?

@bieehoang

class ItemListView(ListView):

Again, if this is a ListView you won’t have a id on the self.kwargs.
So this code

@bieehoang

    def get_queryset(self):
        return TodoItem.objects.filter(todo_list_id = self.kwargs["list_id"])

And this code

@bieehoang

    def get_context_data(self, **kwagrs):
        context = super().get_context_data()
        context["todo_list"] = ToDoList.objects.get(id = self.kwargs["list_id"])
        return context

Will not work.

You said that wants to filter by some date, but on your views you’re trying to filter by a ID.

@bieehoang

Inside class ItemListView i created 2 just to override get_query(() and get_context_data() to restrict date which I want it return. But really my logic was crash some where

Do you still want to filter by ID or you want to filter by some date?
