Easily setup and use batman.js (0.8.0) with rails 3.1

Rails 3.1 setup

This gem requires the use of rails 3.1, coffeescript and the new rails asset pipeline provided by sprockets.

This gem vendors the latest version of batman.js for Rails 3.1 and greater. The files will be added to the asset pipeline and available for you to use.


In your Gemfile, add this line:

gem "batman-rails"

Then run the following commands:

bundle install
rails g batman:install

Layout and namespacing

Running rails g batman:install will create the following directory structure under app/assets/javascripts/:


It will also create a toplevel app_name.coffee file to setup namespacing and setup initial requires.


batman-rails provides 3 simple generators to help get you started using batman.js with rails 3.1. The generators will only create client side code (javascript).

Model Generator

rails g batman:model

This generator creates a batman model and collection inside app/assets/javascript/models to be used to talk to the rails backend.


rails g batman:controller

This generator creates a batman controller for the given actions provided.


rails g batman:scaffold

This generator creates a controller, helper and mode to create a simple crud single page app

Example Usage

Created a new rails 3.1 application called blog.

rails new blog

Edit your Gemfile and add

gem 'batman-rails'

Install the gem and generate scaffolding.

bundle install
rails g batman:install
rails g scaffold Post title:string content:string
rake db:migrate
rails g batman:scaffold Post title:string content:string

You now have installed the batman-rails gem, setup a default directory structure for your frontend batman code. Then you generated the usual rails server side crud scaffolding and finally generated batman.js code to provide a simple single page crud app.
