HAML and "each" last index by Vivien Leroy and wrote 30 September 2012
Still coding my blog, I just encountered a quite simple problem. How to distinguish the last element from a Ruby each loop.
Well it's quite simple in fact and here's how to do it :
- @posts.each_with_index do |post, index| = render post - if index != @posts.size - 1 %hr
So you replace each by each_with_index and now you get the index along with the object and you can easily check if it's last object by querying the size of the array.
Update (as @Kaoo pointed out there's an even more clean solution) :
- @posts.each do |post| = render post - if post != @posts[-1] %hr
Now you're good to go !
