models.Manager

I still don't get why are we using PostManager(models.Manager) and his method live() instead of keep using directly get_queryset() from PublishedPostsMixin(object). What is the advantage? At least to me it seems just less self-explicable when reading the code

It's less explicit if you don't ever read the models.py, yes.

What's important, though, is it keeps you from repeatedly typing that .filter() every time, potentially fat-fingering something or forgetting it.

You could also have done something like:

class PostListView(ListView):
    model = Post
    queryset = Post.objects.live()

but I prefer the explicitness of overriding get_queryset() in the mixin.
