Atom Feed Helper

Makes it easier to create atom feeds through Builder.

Example

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

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

   end

1. 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)
end

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

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

...returns:
