I decided to go through the tutorial. After I create a new app and add new user:string email:string and then perform rake db:migrate in the app directory, I get this output:

rake aborted! 
undefined method `task' for #<DemoApp::Application:0x00000100e49e08>

I am using RVM too ruby 1.9.2 and rails 3.0.7 as in the tutorial. Any thoughts?

This is happening because the latest version of Rake (0.9.0) is broken on Rails 3.0 applications and we are currently awaiting a solid fix.

Right now, a way around this error is to add this line above the load_tasks line in your application's Rakefile:

<AppName>::Application.send :include, ::Rake::DSL if defined?(::Rake::DSL)

Another solution is to require rake 0.8.7 in your Gemfile before starting a new rails project.

# Gemfile
gem 'rake', '0.8.7', :require => 'rake'

then run bundle install
