      <div class='lecture-list-wrapper'>

            <% name = lecture.id + "th - "+ lecture.title %>
            <span><%= link_to name, lecture, class: 'btn-lightgreen' %></span>
            <span><%= link_to 'Edit', edit_lecture_path(lecture), class: 'btn-darkyellow' %></span>
            <span><%= link_to 'Destroy', lecture, method: :delete, class: 'btn-darkorange', data: { confirm: 'Are you sure?' } %></span></p>

OJ1987 answer is fine, though I prefer using interpolation in such cases:

<% name = "#{lecture.id}th - #{lecture.title}" %>

Instead of:

<% name = lecture.id + "th - "+ lecture.title %>

Try: Note: If you want it as variable, ideally use _ underscore not - dash. As code below.

<% name = lecture.id.to_s + "th_"+ lecture.title %>
