django query get last n records

Question

Lets say I am implementing a message stream, records sort by ID ascending order, each fetch request, I want to only allow to fetch the most latest 10 records.

I trie

Answer 1

If you want last X records sorted in descending order by id , Then I don't think you need since filter

last_ten = Messages.objects.all().order_by('-id')[:10]

Using -id will sort in descending order. Hope this was helpful !!

Answer 2

Or use [::-1] instead of reversed:

last_ten = Messages.objects.filter(since=since).order_by('-id')[:10][::-1]

Answer 3

You can pass your queryset to reversed:

last_ten = Messages.objects.filter(since=since).order_by('-id')[:10]
last_ten_in_ascending_order = reversed(last_ten)
