Question about auto completion field

rubyonrails-talk

Dear all

I am reading a rails cookbook about the auto_complete_for function, the code as below

app/controllers/musicians_controller.rb:

class MusiciansController < ApplicationController

  auto_complete_for :musician, :name

  def index   end

  def add     # assemble a band...   end end

app/views/musicians/index.rhtml:

<h1>Musician Selection</h1>

<% form_tag :action => :add do %>   <%= text_field_with_auto_complete :musician, :name %>   <%= submit_tag 'Add' %> <% end %>

My question is that, if the name attribute consists lots of duplicated values, how can I distinct them before pass to auto_complete_for? I afraid the performance would be affected if not to distinct it.

Thank you very much.

Valentino
