Hi all, Here''s another contribution for anyone interested. In Railscast episode 28, Ryan Bates showed us in_groups_of which allows you to group array members such as >> list = [1, 2, 3, 4, 5, 6, 7] => [1, 2, 3, 4, 5, 6, 7] >> list.in_groups_of(3) => [[1, 2, 3], [4, 5, 6], [7, nil, nil]] This allows you to iterate over the groups and, for example, display a list
