module Rails3JQueryAutocomplete
# Inspired on DHH's autocomplete plugin
#
# Usage:
#
# class ProductsController < Admin::BaseController
# autocomplete :brand, :name
# end
#
# This will magically generate an action autocomplete_brand_name, so,
# don't forget to add it on your routes file
#
# resources :products do
# get :autocomplete_brand_name, :on => :collection
# end
#
# Now, on your view, all you have to do is have a text field like:
#
# f.text_field :brand_name, :autocomplete => autocomplete_brand_name_products_path
#
#
