Views.py

You didn't define the model name on the view.Add the model name and try to add custom context_object_name. For reference check this

class BookListView(generic.ListView):
    model = Book
    context_object_name = 'my_book_list'   # your own name for the list as a template variable
    queryset = Book.objects.filter(title__icontains='war')[:5] # Get 5 books containing the title war
    template_name = 'books/my_arbitrary_template_name_list.html'  # Specify your own template name/location

You have to specify which model to create ListView. Here in your case define model=Post as

from django.views.generic.list import ListView

class PostList(ListView):
    model = Post
    template_name = 'blog/index.html'
    queryset = Post.objects.filter(status=1).order_by("-created_on")

Or you can also use get_queryset() as

from django.views.generic.list import ListView

class PostList(ListView):

    # specify the model
    model = Post
    template_name = 'blog/index.html'

    def get_queryset(self, *args, **kwargs):
        qs = super(PostList, self).get_queryset(*args, **kwargs)
        qs = qs.filter(status=1).order_by("-created_on")
        return qs
