I would like to to do the following, any ideas

I have a Products model with two fields, both strings.

I would like on the index pages for the products to display the Name in Red if the Positions field is blank in the database.

<span class="<%= product.position.nil? ? "red" : "blue" %>">
  <%= product.name %>
</span>

Update:

Let's say you have code like you provided in comment, modify it to:

<td>
  <%= link_to admin_printer_path(printer), :class => 'ico' do %>
    <b<%= ' class="error"' unless printer.position? %>><%= printer.name %></b>
  <% end %>
</td>

and in css file/section in header add (or modify according to your structure):

.error { color: red; }

Create helper method to check if object is blank?

def set_css_class(object, css_class)
  " #{css_class}" if object.blank?
end

Call it in your View:

<div class="name <%= set_css_class(@poroduct.position, 'red') %>">
  <%= @product.name %>
</div>
