How to make will_paginate loop back to first on last entry?

If on the l开发者_运维知识库ast item of a collection, I'd like a "next" link that displays the first item again.

Not too sure about Ruby, but in php you would have a count of your rows. You could then make some kind of if statement to change the next link to the beginning of your results..

$base_url = 'http://google.com/paging?p=';
$count = 100;
$per_page = 10;
$page = $_GET['p'];

if($page > $count/$per_page){

   $prev_link = $page - $per_page;
   $next_link = $base_url;

}

Let me know if that helps.
