Adds helpers for Rails views and controller in order to manage 'dynamic select'. It uses jQuery UI as support for inobtrusive use in forms. It's not the classic Autocompleter, its use is limited to belongs_to reflections.

Rails 3.0

ComboBox requires the gem jquery-rails, so if you don't already use it:

rails generate jquery:install --ui

Then install combo_box in your app like jquery-rails:

rails generate combo_box:install

Then the javascript and/or stylesheet files must be included in the application layout:

<%= javascript_include_tag('combo_box') -%>
<%= stylesheet_link_tag('combo_box') -%>

Rails 3.1

Nothing to install. With the asset pipeline, there is no need to run generators or copy files. So for stylesheets:

# app/assets/stylesheets/application.css
*= require combo_box

And for javascripts:

# app/assets/javascripts/application.js
//= require combo_box


Classic usage in resource forms:

# app/controllers/orders_controller.rb
class OrdersController < ApplicationController
  search_for :client

# app/views/orders/_form.html.haml
combo_box :order, :client

Usage in non-resource forms with personalized controller method:

# app/controllers/orders_controller.rb
class OrdersController < ApplicationController
  def search_for_orders
    orders = Order.find_all_by_number(params[:term])
    render orders.collect{|r| {:label=>r.number, :id=>}}.to_json

# app/views/orders/search.html.haml
combo_box_tag "search", :search_for_orders

Contributing to ComboBox

  • Check out the latest master to make sure the feature hasn't been implemented or the bug hasn't been fixed yet

  • Check out the issue tracker to make sure someone already hasn't requested it and/or contributed it

  • Fork the project

  • Start a feature/bugfix branch

  • Commit and push until you are happy with your contribution

  • Make sure to add tests for it. This is important so I don't break it in a future version unintentionally.

  • Please try not to mess with the Rakefile, version, or history. If you want to have your own version, or is otherwise necessary, that is fine, but please isolate to its own commit so I can cherry-pick around it.
