How to structure a layout template in Haml

This solution is for Ruby on Rails only:

You can use yield(:location) and the content_for(:location) methods. "Using the content_for Method" has more information.

layout.haml:

!!!
%html
  %head
    %title= yield(:title)
    = yield(:head)
  %body
    = yield

view.haml:

- content_for(:title, 'My title')
- content_for(:head) do
  = javascript_include_tag :foo

%h1 My view!

I use partials:

!!!
%html
  = partial('trst_sys/shared/html-head')

  %body{:id => "srv",:'data-lang' => current_lang}
  #main.wrap
    %header#header
      = partial('trst_sys/shared/header')
    %nav#menu
      = partial('trst_sys/shared/menu')
    %section#content
      %article#xhr_content
        = yield
      %article#xhr_msg.hidden
    %section#sidebar
      = partial('trst_sys/shared/sidebar')
    %section#main_footer.wrap
  %footer#footer.wrap
    = partial('trst_sys/shared/footer')
