Este helper facilita la creación de un feed Atom. He aquí un ejemplo de uso completo:

config/routes.rb

resources :articles

app/controllers/articles_controller.rb

def index
  @articles = Article.all
 
  respond_to do |format|
    format.html
    format.atom
  end
end

app/views/articles/index.atom.builder

atom_feed do |feed|
  feed.title("Articles Index")
  feed.updated(@articles.first.created_at)
 
  @articles.each do |article|
    feed.entry(article) do |entry|
      entry.title(article.title)
      entry.content(article.body, type: 'html')
 
      entry.author do |author|
        author.name(article.author_name)
      end
    end
  end
end
