Module: RailsAutocomplete::Autocomplete::ClassMethods

Defined in:
lib/rails-autocomplete/autocomplete.rb

Overview

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

Yajl is used by default to encode results, if you want to use a different encoder you can specify your custom encoder via block

class ProductsController < Admin::BaseController

autocomplete :brand, :name do |items|
  CustomJSONEncoder.encode(items)
end

end
