+module ActionView

+      # Produces a wrapper DIV element with id and class parameters that
+      # relate to the specified Active Record 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 Active Record object. For example:
+      #
+      #    <% content_tag_for(:tr, @person) do %>
+      #      <td><%=h @person.first_name %></td>
+      #      <td><%=h @person.last_name %></td>
+      #    <% end %>
+      #
+      # would produce the 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 <tt>:class</tt> 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.extract_options!
+        options.merge!({ :class => "#{dom_class(record)} #{options[:class]}".strip, :id => dom_id(record, prefix) })
+        content_tag(tag_name, options, &block)
+      end
