Sankofa Journal Step 7: Real Queries

Replace the hard-coded lists in your views with real queries. The index shows published posts newest first, the tag and author views filter accordingly, and the detail view uses get_object_or_404. Then install Django Debug Toolbar and look at the query count on the index page. Fix whatever N+1 you find with select_related or prefetch_related, and write down the before and after numbers. That measurement is the whole point of the exercise.
