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 :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">...
