Rails - take(4) but the bottom not the top?

Question

I have @comments which lets say has 17 records

What I want is the last 4: 14,15,16,17

I tried:

<% @comments.take(4).each do |comment| %>

But that returns the first 4.. How can I grab the last 4 comments, not the first 4

Thanks

Answer 1

You could also do:

@comments.last(4)...

Answer 2

<% @comments.reverse.take(4).each do |comment| %>
