#change_set_iter(change_set, &block) ⇒ Object

Allows you to iterate over a given Audit#change_set. Given a block, each time yield is called, it will return the attribute, the old version and the new version as arguments. If the Audit is a message audit, it will set the new attribute to the audit message.

Example:

<% change_set_iter(audit.change_set) do |attr, old, new| %>
  <p class="audit"><strong><%=h attr %></strong>
    <% if audit.message %>
      <em><%= new %></em>
    <% else %>
      changed from <em><%=h old %></em> to <em><%=h new %></em>.
    <% end %>
  </p>
<% end %>
