Integrate Select2 javascript library with Rails asset pipeline

Select2 for rails asset pipeline

Select2 is a jQuery based replacement for select boxes. It supports searching, remote data sets, and infinite scrolling of results.

The select2-rails gem integrates the Select2 jQuery plugin with the Rails asset pipeline.

Usage

Install select2-rails gem

Add select2-rails to your Gemfile and run bundle install:

gem "select2-rails"

Include select2-rails javascript assets

Add the following to your app/assets/javascripts/application.js:

//= require select2

To add select2-full.js instead of select2.js, add the following instead :

//= require select2-full

Include select2-rails stylesheet assets

Add to your app/assets/stylesheets/application.css:

*= require select2

If you are using Twitter Boostrap you need to also require the bootstrap theme CSS in addition to the above require.

*= require select2-bootstrap

To apply the theme, tell Select2 to do so by passing bootstrap to the theme option when initializing Select2:

$( "#dropdown" ).select2({
    theme: "bootstrap"
});

Internationalization (i18n)

The select2-rails now supports multiple languages.

Add the following to your app/assets/javascripts/application.js:

//= require select2_locale_"any possible language"

Possible languages:

ar, az, bg, ca, cs, da, de, el, en, es, et, eu, fa, fi, fr, gl, he, hi, hr, hu, id, is, it, ja, km, ko, lt, lv, mk, ms, nb, nl, pl, pt, pt-BR, ro, ru, sk, sr, sr-Cyrl, sv, th, tr, uk, vi, zh-CN, zh-TW

Fix

IE8 Invalid Character

IE8 doesn't support some unescaped Unicode character and need to quote keys in object literals You need some configurations for Uglifier to do the work. Add to your config/environments/production.rb

   require 'uglifier'
   config.assets.js_compressor = Uglifier.new(output: {ascii_only: true, quote_keys: true})

Version

From v2.1.0 on, select2-rails's version will match the version of Select2 it uses.

The last number of the version is the patch version specific to the gem. For example, for a version of the form 2.x.y, 2.x is the release of Select2 we should be compatible with, and y is the patch version specific to the gem (ie. to resolve any gem-specific issues that crop up).
