This error comes when there is a {% url %} tag that is not set up properly -
like the views.py line highlighted below. So, I suspect you have such a tag say
tied to a button on the html page, but it isn’t included in this thread.
There’s another error in the code not related to your reverse error - the view
passes in ‘posts’ as the context name but the template processes ‘post’:
post.title, post.xxxx, etc. Those have to match in order for the DB values to
be displayed.
I’d go back through the djangogirls tutorial again and be positive everything
is typed in correctly. That should fix it.

Below, post is a DB row, not an ID as the URL.py requires.
Change the view as:
return render(request, ‘blog/post_details.html’, {‘pk’: posts[‘id’]})
