You only need some files included in the template:

    stylesheet_link_tag 'default'
    stylesheet_link_tag 'alert'
    javascript_include_tag :defaults
    javascript_include_tag 'window'
    

And then you can call the helpers in your views

link_to_prototype_dialog( 'Link', 'Hello world', 'alert' ) -- Link

link_to_prototype_confirm_url( 'Link', 'Go to google?', 'http://google.com', nil, { :windowParameters => {:className => 'alphacube'} } ) -- Link

link_to_prototype_window( 'Link', 'window_id', { :title => 'Window title', :left => 200, :top => 200 }) -- Link

You can get the helper here (v0.11.0)
