Question

Currently I have

    <b>Step 1</b>    
      <%= @recipe_records.instruct_1 %>
     </p>   
    <p> 
    <b>Step 2</b>       
      <%= @recipe_records.instruct_2 %>
      </p>
    .....
    <b>Step 30</b>      
      <%= @recipe_records.instruct_30 %>
      </p>

How do I put it in a loop instead of listing all 30 steps and to not display empty steps?

    <% 30.times do |n|%>
        <% ri = @recipe_records.instruct_#{n+1}%>
        <%= if !ri.empty? %>
            <p>
            <%= ri %>
        <% end%>
    <% end %>

Tried but unable to work.

After some fidling, I’ve got the following working codes:

<% 30.times do |n|%>
    <% ri = @recipes.send("instruct#{n+1}")%>
    <% unless ri.blank? %>
        <p>
        <b><%= "Step #{n+1}"%></b>
        <%= ri %>
        <p/>
    <% end%>
<% end %>
