Rails: How do I have a zero if there is no data? -

-

currently if user sells see box witha price. if haven't sold box disapears , see sales. how leave number $0 if user didn't sell instead of clear blank?

thanks

<% if current_user %>               <sold>                <li><%= link_to "sales", current_user %>               <% @sales.each |sale| %>             <div class="sold-count">$<%= sale.amount / 100 %></ %></div>  </li> </sold>         <% end %>

right you're iterating on sales each sale, if size of container zero, loop going skipped.

you need add conditional check see if sales empty, @sales.empty? , if is, show 0. 

<% if @sales.empty? %>     <div class="sold-count"> $0 </div>  </li> </sold> <% end %>
