+module RecordTagHelper
+  # Produces a wrapper DIV element with id and class parameters that
+  # relate to the specified ActiveRecord object. Usage example:
+  #
+  #    <% div_for(@person, :class => "foo") do %>
+  #       <%=h @person.name %>
+  #    <% end %>
+  #
+  # produces:
+  #
+  #    <div id="person_123" class="person foo"> Joe Bloggs </div>
+  #
+  def div_for(record, *args, &block)
+    content_tag_for(:div, record, *args, &block)
+  end
+  
+  # content_tag_for creates an HTML element with id and class parameters
+  # that relate to the specified ActiveRecord object. For example:
+  #
+  #    <% content_tag_for(:tr, @person) do %>
+  #      <td><%=h @person.first_name %></td>
+  #      <td><%=h @person.last_name %></td>
+  #    <% end %>
+  #
+  # would produce hthe following HTML (assuming @person is an instance of
+  # a Person object, with an id value of 123):
+  #
+  #    <tr id="person_123" class="person">....</tr>
+  #
+  # If you require the HTML id attribute to have a prefix, you can specify it:
+  #
+  #    <% content_tag_for(:tr, @person, :foo) do %> ...
+  #
+  # produces:
+  #    
+  #    <tr id="foo_person_123" class="person">...
+  #
+  # content_tag_for also accepts a hash of options, which will be converted to
+  # additional HTML attributes. If you specify a +:class+ value, it will be combined
+  # with the default class name for your object. For example:
+  #
+  #    <% content_tag_for(:li, @person, :class => "bar") %>...
+  #
+  # produces:
+  #
+  #    <li id="person_123" class="person bar">...
+  #
+  def content_tag_for(tag_name, record, *args, &block)
+    prefix  = args.first.is_a?(Hash) ? nil : args.shift
+    options = args.first.is_a?(Hash) ? args.shift : {}
+    concat content_tag(tag_name, capture(&block), 
+      options.merge({ :class => "#{dom_class(record)} #{options[:class]}".strip, :id => dom_id(record, prefix) })),
