Use the Rails Composer tool instead. The Rails Composer tool creates the example applications for the RailsApps project. The tool gives you a Rails 3.2 starter app you can deploy in minutes.
Before generating your application, you will need:
- The Ruby language (version 1.9.3)
- Rails 3.2
See Installing Rails for detailed instructions and advice.
To build a Rails application, run the command (where myapp is the name of your application):
$ rails new myapp -m https://raw.github.com/RailsApps/rails-composer/master/composer.rb
You can use the -T flag to skip Test::Unit files or the -O flag to skip Active Record files:
$ rails new myapp -m https://raw.github.com/RailsApps/rails-composer/master/composer.rb -T -O
The rails new command creates a new Rails application. If you want to use a template for every Rails application you build, you can set options for the rails new command in a .railsrc file in your home directory. Here’s how to set up a .railsrc file to use a template when you create a new Rails application:
# ~/.railsrc -m https://raw.github.com/RailsApps/rails-composer/master/composer.rb
Problems? Check the issues for the rails_apps_composer gem.
You should review the article Installing Rails to make sure you’ve updated all the components that are required to run Rails successfully.
Are you getting an error “OpenSSL certificate verify failed” when you try to generate a new Rails app from an application template? See suggestions to resolve the error Certificate Verify Failed.
If you get a “segfault” when you try rails new, try removing and reinstalling rvm.
The application templates are assembled from recipes supplied by the rails_apps_composer gem. See the rails_apps_composer project to understand how the application templates work.
If you wish to change a template to generate an app with your own customized options, you can copy and edit the template file. However, it is better to use the rails_apps_composer gem to create a new application template. You’ll find newer versions of the recipes that make up the application template. You may find issues have been identified and (perhaps) fixed. And it will be easier to maintain your application template if you work from the rails_apps_composer gem.
To understand the code in these templates, take a look at Thor::Actions. Your recipes can use any methods provided by Thor::Actions or Rails::Generators::Actions.

You can also try Rails Hotline, a free telephone hotline for Rails help staffed by volunteers.
Please make changes to the rails_apps_composer gem rather than changing the application templates.
