title: Mark ActiveRecord attribute as html_safe
body: <p>We have an ActiveRecord model with an html attribute (say <code>Post#body</code>). Is there a nice way that calling <code>body</code> on a <code>post</code> returns an <code>html_safe?</code> string? E.g.:</p>
  
  <pre><code>class Post &lt; ActiveRecord::Base
    # is_html_escaped :body or somesuch magic
  end
  
  Post.first.body.html_safe? # =&gt; true
  </code></pre>
  
  <p>The problem otherwise is that we have to call <code>raw</code> everything we show that field.</p>
