A gem to automate using jQuery with Rails 3

README.md

jquery-rails

jQuery! For Rails! So great.

This gem provides:

  • jQuery 1.11.0
  • the jQuery UJS adapter
  • assert_select_jquery to test jQuery responses in Ruby tests

Versions

Starting with v2.1, the jquery-rails gem follows these version guidelines to provide more control over your app's jquery version from your Gemfile:

patch version bump = updates to jquery-ujs, jquery-rails, and patch-level updates to jquery
minor version bump = minor-level updates to jquery
major version bump = major-level updates to jquery and updates to rails which may be backwards-incompatible

See VERSIONS.md to see which versions of jquery-rails bundle which versions of jQuery.

Installation

Apps generated with Rails 3.1 or later include jquery-rails in the Gemfile by default. So just make a new app:

rails new myapp

If upgrading from an older version of rails, or for rails 3.0 apps, add the jquery-rails gem to your Gemfile.

gem "jquery-rails"

And run bundle install. The rest of the installation depends on whether the asset pipeline is being used.

Rails 3.1 or greater (with asset pipeline enabled)

The jquery and jquery-ujs files will be added to the asset pipeline and available for you to use. If they're not already in app/assets/javascripts/application.js by default, add these lines:

//= require jquery
//= require jquery_ujs

For jQuery UI, we recommend the jquery-ui-rails gem, as it includes the jquery-ui css and allows easier customization.

As of v3.0, jquery-rails no longer includes jQuery UI. Use the jquery-ui-rails gem above.

Rails 3.0 (or greater with asset pipeline disabled)

This gem adds a single generator: jquery:install. Running the generator will remove any Prototype JS files you may happen to have, and copy jQuery and the jQuery-ujs driver for Rails to the public/javascripts directory.

This gem will also hook into the Rails configuration process, removing Prototype and adding jQuery to the javascript files included by the javascript_include_tag(:defaults) call. While this gem contains the minified and un-minified versions of jQuery, only the minified versions will be included in the :defaults when Rails is run in production or test mode (un-minified versions will be included when Rails is run in development mode).

To invoke the generator, run:

rails generate jquery:install

You're done!

As of v3.0, jquery-rails no longer includes jQuery UI, you will need to install it by yourself as needed.

Contributing

Feel free to open an issue ticket if you find something that could be improved. A couple notes:

  • If it's an issue pertaining to the jquery-ujs javascript, please report it to the jquery-ujs project.

  • If the jquery scripts are outdated (i.e. maybe a new version of jquery was released yesterday), feel free to open an issue and prod us to get that thing updated. However, for security reasons, we won't be accepting pull requests with updated jquery scripts.

Acknowledgements

Many thanks are due to all of the jquery-rails contributors. Special thanks to JangoSteve for tirelessly answering questions and accepting patches, and the Rails Core Team for making jquery-rails an official part of Rails 3.1.
