[Ruby] A to Z only linking to letters with content

2008-01-13T21:10:09+00:00

I wanted A to Z anchor links at the top of the page to include the full alphabet but only to link when there is related content below. Can this be made better somehow?

## Controller
@a_to_z = Service.find(:all,:select=>'SUBSTR(name,1,1) AS letter',:group=>'SUBSTR(name,1,1)',:order=>'name').collect { |d| d.letter }


## View
<ul class="pagination">
<% for letter in 'A'..'Z' %>
	<li><%= @a_to_z.index(letter) ? link_to(letter,:l=> letter) : content_tag(:a,letter,:class=>'f') %></li>
<% end %>
</ul>
