Answer 1

Here is a plugin for creating sitemaps in Ruby on Rails: Ruby on Rails sitemap plugin. It takes care of most of the sitemap logic and generation. The plugin is from my homepage.

Example configuration:

Sitemap::Map.draw do

  # default page size is 50.000 which is the specified maximum at http://sitemaps.org.
  per_page 10

  url root_url, :last_mod => DateTime.now, :change_freq => 'daily', :priority => 1

  new_page!

  Product.all.each do |product|
    url product_url(product), :last_mod => product.updated_at, :change_freq => 'monthly', :priority => 0.8
  end

  new_page!

  autogenerate  :products, :categories,
                :last_mod => :updated_at,
                :change_freq => 'monthly',
                :priority => 0.8

  new_page!

  autogenerate  :users,
                :last_mod => :updated_at,
                :change_freq => lambda { |user| user.very_active? ? 'weekly' : 'monthly' },
                :priority => 0.5

end
