You can use Rails Composer, “the Rails generator on steroids,” to create any of the Rails 4.1 example applications from the RailsApps project. In minutes you get a starter app, ready to customize and deploy.
Here’s the newest starter app you get with Rails Composer:
Devise is for authentication and user management. You might not know Pundit. It’s a great new gem for authorization and access control, simpler than CanCan and easier to use with Rails 4.1. Together with options for Bootstrap or Foundation, you get a powerful starter app in minutes with Rails Composer.
Make sure you have Rails 4.1.0.rc1 installed and run:
$ rails new myapp -m https://raw.github.com/RailsApps/rails-composer/master/composer.rb
You’ll get a menu of starter apps. Choose options for ERB or Haml or Slim, different databases, and Bootstrap or Foundation front-end frameworks.
