AtomFeedHelper

Makes it easier to create atom feeds through Builder.

Example

from PostsController

def index @posts = Post.find(:all, :limit => 25)

respond_to do |format|
  format.html
  format.atom
end

end

from posts/index.atom.builder

atom_feed(:url => formatted_people_url(:atom)) do |feed| feed.title("Address book") feed.updated(@people.first ? @people.first.created_at : Time.now.utc)

for post in @posts
  feed.entry(post) do |entry|
    entry.title(post.title)
    entry.content(post.body, :type => 'html')

    entry.author do |author|
      author.name(post.creator.name)
      author.email(post.creator.email_address)
    end
  end
end

end

...returns:
