Order in list

I have this code:

<% form_for(@repair_ticket) do |f| %>
  <p>
  <%= text_field_with_auto_complete :rp_part, :name %>
   <p>
   <b>Client</b><br />
  <select name="repair_ticket[client_id]">
   <% @clients.each do |client| %>
       <option value="<%= client.id %>"
         <%= ' selected' if client.id == @repair_ticket.client_id %>>
         <%= client.name %>
       </option>
   <% end %>
  </select></p>

How can I ;order => client.name all the results in the list ?
