Or something like this:

  def flash_messages     messages =     %w(notice warning error).each do |msg|       messages << content_tag(:div, html_escape(flash [msg.to_sym]), :id => "flash-#{msg}") unless flash[msg.to_sym].blank?     end     messages   end

<%= flash_messages %>

Another similar method...

def show_flash     [:notice, :warning, :message].collect do |key|       content_tag(:div, flash[key], :class => "flash_#{key}") unless flash[key].blank?     end.join end
