haml - ruby - if string is not contained within an array -

I want to output only one anchor if the current_page is in the array then let me (.html and -nf.html) get. If this is not in the array then I will get many anchors because there are items in the array I

I am using.

- If page_f [[current_indix]]

 If you want your first search to be the only one, you can break each loop. But now it looks a bit weird because you are running on an array again and after breaking the first element, whatever it may be. Am I completely addressing your problem?
