Lets imagine you are creating a view for returning all the courses with some of their authors data. If you run a code like this:

queryset = Course.objects.all()
courses = []
for course in queryset:
  courses.append({"title": course.title, "author": course.author.name})

This is executing one query (for bringing all courses) and N queries more (one for each author). There is the library nplusone to detect this.
