Module: Rails3JQueryAutocomplete::ClassMethods

Defined in:
lib/rails3-jquery-autocomplete.rb

Overview

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
