I noticed that DRF mentions N+1 problems briefly in a note under get_queryset(), but it doesn’t give any proper explanation or examples.
I added a new section about performance and N+1 queries. It explains why the issue happens and how to use
select_relatedandprefetch_relatedinget_queryset()for generic views and viewsets. I also included short examples.The goal is to make it clearer for new people and avoid confusion.
