This plugin provides a auto-complete method for your controllers to be used
with Dylan Verheul's jquery autocomplete plugin. This jQuery plugin is not
included, and can be obtained from:
This auto_complete_jquery plugin is just a modified version of the standard
Rails auto_complete plugin. It provides the same auto_complete_for method
for your controllers, but eliminates the various view helper methods, as
those are not needed when using jQuery and Unobtrusive JavaScript.
To use this, you need to have jQuery and the autocomplete plugin mentioned
above (as well as appropriate CSS). Then, there are four aspects of setting
up an auto-complete field:
1) Create the text field in your view, which is just a regular form text
field as you'd create in a Rails erb view:
<%= post.text_field :title, :autocomplete =>"off" %>
2) Include the appropriate JS files and CSS in your layout or similar:
<%= stylesheet_link_tag 'jquery.ui.autocomplete' %>
<%= javascript_include_tag 'jquery.min', 'jquery.dimensions.min', 'jquery.templating', 'jquery.ui.autocomplete.ext', 'jquery.ui.autocomplete', :cache => 'jquery' %>
3) Use the auto_complete_for controller macro to generate the appropriate
auto-complete method in your controller, such as:
# Controller
class BlogController < ApplicationController
auto_complete_for :post, :title
4) Hook up the text field's autocomplete event in your JavaScript file
using jQuery and the jquery-autocomplete plugin mechanism, for example:
$(document).ready(function() {
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'
