Example (updated for Rails 3):
# config/routes.rb
..
post "/blog/auto_complete_for_post_title" => "blog#auto_complete_for_post_title"
..
# Controller
class BlogController < ApplicationController
auto_complete_for :post, :title
end
# View
<%= text_field_with_auto_complete :post, :title %>
# stylesheets
(this is not necesary or even the best fit, but a quick working solution if the boxes doesn't fit nicely below the auto complete textbox)
* { margin:0; padding:0; }
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'
