Thanks super, Greg, for helping me out. I'm dense, 'cause I couldn't
figure out the syntax for 'whatever'. I did get this to work in
the .erb file:
<% if Item.find( item ).orders.size > 0 %>
<%=h "Found #{item.title} in Orders" %>
<% end %>
But I'm just wondering... is that the most efficient way to do it? Is
there a more efficient way?
Thanks for putting in the time to help this noob out,
Craig
