| + | 'username': 'usertest1', | ||
| + | 'email': email, | ||

| + | |||
| + | ====== Articles ====== | ||
| + | |||
| + | ===== N+1 Queries ===== | ||
| + | |||
| + | 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: | ||
| + | <code python> | ||
| + | queryset = Course.objects.all() | ||
| + | courses = [] | ||
| + | for course in queryset: | ||
| + | courses.append({"title": course.title, "author": course.author.name}) | ||
| + | </code> | ||
| + | This is executing one query (for bringing all courses) and N queries more (one for each author). There is the library [[https://github.com/jmcarp/nplusone|nplusone]] to detect this. | ||
