Module: JqueryAutocomplete::ClassMethods

Defined in:
lib/jquery_autocomplete.rb

Overview

Example:

# Controller
class BlogController < ApplicationController
  auto_complete_for :post, :title
end

# View
<%= text_field_with_auto_complete :post, title %>

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'
 def auto_complete_for(object_name, method_name, options = {})
