Best way to get last n items?

[sturdy zenith]

This works but it seems weird that I'm doing reverse in python. Is there a more idiomatic way to get last n but keep them in the right order?

last_n = list(queryset.order_by('-time_created')[:n])[::-1]

why not queryset.order_by("time_created")[:n]?

i.e., flip around the ordering

if you also need the stuff in the reverse order, do a second query. That could be more efficient than grabbing the list once, and reversing it in memory

last_n = list(queryset.order_by('time_created')[:n])
first_n = list(queryset.order_by('-time_created')[:n])

also you might not need the list
