Question

Is there a shorthand for doing the following:

  <% @ticket.notes.each do |n| %>
    <% if n != @ticket.notes.last %>
      <div class="note">
        <p class="author">Note by <b>n.user.name</b></p>
        <p class="time"><%= time_ago_in_words(n.created_at) %></p>
        <p class="copy"><%= n.content %></p>
      </div>
    <% end %>
  <% end %>

So that there is no need to check if the item is the last item.

Answer 1

You should slice the array beforehand:

<% @ticket.notes[0..-2].each do |n| %>
  <div class="note">
    <p class="author">Note by <b>n.user.name</b></p>
    <p class="time"><%= time_ago_in_words(n.created_at) %></p>
    <p class="copy"><%= n.content %></p>
  </div>
<% end %>
