How to slice last N data Django

For example I have 5 row with data in my db and when I want to show first 3 row in my html, I'm using for loop with slice like {% for x in y|slice:":3" %}. But now my question is how to show last 3 row from db.

Solution

  • I would really advice you not to slice querysets in a template, but in the view. Normally a view decides what to show in the response, and a template decide how to show that in the response.

    You can slice a queryset in the response with .reverse()[:3]. So if your view has a queryset:

    SomeModel.objects.all()

    you can slice the queryset with:

    SomeModel.objects.all().reverse()[:3]
