Ruby loop though arrays

Question

I want to loop through each item in an array, but the last variable could be an array itself:

<% [@in_force_item, @draft_item,@historical_items].compact.each do |item| %>

it seems to fail at this line:

 <td>
  <%= datetime_to_string item.updated_at %>
 </td>

Is it because the historical_items is actually an array?

Yes, you can't call .updated_at on the array. Just flatten the array before your iteration:

<% [@in_force_item, @draft_item,@historical_items].compact.flatten.each do |item| %>

Or just splat it: [@in_force_item, @draft_item, *@historical_items].each ...
