Collections in groups?

Rails

Is there a way to traverse an array and perform an action (like
collect) in sets? I am trying to use an array to populate a table
with three cells per row, so I need to pop in sets of three, then
create a new row.

Thanks,
JB

you need the method in_groups_of. Here’s how I use it

    <table>
      <% @products.in_groups_of(2, '&nbsp;')  do |item| -%>
        <tr class="<%= cycle("item0","item1") %>">
          <% item.each do |item| next unless

item.respond_to?(:product_name) -%>

<%= item.product_name %>

<% end -%>

<% end -%>
