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
  #
  #
