I'd go with orders.empty?
You will want to do your find in the controller. Set the results to
an instance variable.
@item = Item.find(...)
Then that instance variable is available in your view:
<%= debug @item %>

Depends on your app. You might want that :include => :items or you
might not. It'll save a bunch of smaller queries later if you leave
it off, but then what if you needed all those items? It's up to you.
