Auto_complete is a project mainly written in ..., it's free.
Fork of rails auto_complete plugin to work with edge
Example:
class BlogController < ApplicationController auto_complete_for :post, :title end
<%= text_field_with_auto_complete :post, title %>
By default, auto_complete_for limits the results to 10 entries, and sorts by the given field.
auto_complete_for takes a third parameter, an options hash to the find method used to search for the records:
auto_complete_for :post, :title, :limit => 15, :order => 'created_at DESC'
