Module: AutoComplete::ClassMethods
- Defined in:
- lib/auto_complete/class_methods.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'
For help on defining text input fields with autocompletion, see ActionView::Helpers::JavaScriptHelper.
