Question

I’m just getting started with the new(ish) class-based views, and I am wondering what’s the best way to get select_related() in there. Here’s my view:

class PostDetailView(DetailView):
    model = Post

The post comes from the ‘slug’ in the URL. This works fine, but, I would like to get select_related() in there to reduce the number of queries.

Answer 1

Specify a queryset instead of model:

class PostDetailView(DetailView):
    queryset = Post.objects.select_related()

(See the docs).
