Hello,

Assuming you're after a way of paginating by first letter, here are a few lines of code which I wrote to do this:

routes.rb:

   map.customers 'customers/:letter', :controller => 'customers', :letter => /[a-zA-Z]/

customers_controller.rb:

   def index      # Paginate alphabetically by surname.      if params[:letter] =~ /^[A-Z]$/i        letter = params[:letter].upcase      else        letter = 'A'      end      @customers = Customer.all_by_name "contacts.last_name like '#{letter}%'" # My customers table is joined to my contacts table    end

customers_helper.rb:

   def glossary_index(params)      result = "<p class='glossary-index'>"      ('A'..'Z').to_a.each { |letter|        result << link_to_unless_current(letter, url_for(params.merge(:letter => letter))) {          "<span>#{letter}</span>"        }      }      result << '</p>'    end

stylesheet.css:

   p.glossary-index a { margin: 0.6em; }    p.glossary-index span { margin: 0.6em; }

index.rhtml:

   <%= glossary_index :controller => 'customers' %>

   <% for customer in @customers %>      ...    <% end %>

Hope that helps.
