below is a simple implementation of bread-crumbs for use in ruby on rails, you can pass in the level separator as the first argument and a boolean to indicate inclusion of home link.

it relies on the requested path to work out how to split the breadcrumbs, it alsoo requires that every component of your path is accessable, should be a good starting block though.

  def breadcrumbs(sep = "Â»", include_home = true)
    levels = request.path.split('?')[0].split('/')
    levels.delete_at(0)

    links = "You are here: "
    links += content_tag('a', "home", :href => "/") if include_home

    levels.each_with_index do |level, index|
      links += " #{sep} #{content_tag('a', level.downcase.gsub(/_/, ' '), :href => '/'+levels[0..index].join('/'))}"
    end

    content_tag("div", content_tag("p", links ), :id => "breadcrumb")
  end
