Template Languages

Haml

get '/' do
  haml :index
end

This will render ./views/index.haml

Sass

get '/' do
  sass :styles
end

This will render ./views/styles.sass

Erb

get '/' do
  erb :index
end

This will render ./views/index.erb

Builder

get '/' do
  builder :index
end

This will render ./views/index.builder

get '/' do
  builder do |xml|
    xml.node do
      xml.subnode "Inner text"
    end
  end
end

This will render the xml inline, directly from the handler.

Atom Feed

RSS Feed

Assume that your site url is http://liftoff.msfc.nasa.gov/.

get '/rss.xml' do
  builder do |xml|
    xml.instruct! :xml, :version => '1.0'
    xml.rss :version => "2.0" do
      xml.channel do
        xml.title "Liftoff News"
        xml.description "Liftoff to Space Exploration."
        xml.link "http://liftoff.msfc.nasa.gov/"
        
        @posts.each do |post|
          xml.item do
            xml.title post.title
            xml.link "http://liftoff.msfc.nasa.gov/posts/#{post.id}"
            xml.description post.body
            xml.pubDate Time.parse(post.created_at.to_s).rfc822()
            xml.guid "http://liftoff.msfc.nasa.gov/posts/#{post.id}"
          end
        end
      end
    end
  end
end

This will render the rss inline, directly from the handler.

Layouts

Layouts are simple in Sinatra. Put a file in your views directory named "layout.erb", "layout.haml", or "layout.builder". When you render a page, the appropriate layout will be grabbed (of the same filetype), and used.

The layout itself should call yield at the point you want the content to be included.

An example haml layout file could look something like this:

%html
  %head
    %title SINATRA BOOK
  %body
    #container
      = yield

avoiding a layout

Sometimes you don't want the layout rendered. In your render method just pass :layout => false, and you're good.

get '/' do
  haml :index, :layout => false
end

In File Views

This one is cool:

get '/' do
  haml :index
end
