title: Rails update_attributes without save?
body: <p>Is there an alternative to <code>update_attributes</code> that does not save the record?</p>
  <p>So I could do something like:</p>
  <pre><code>@car = Car.new(:make =&gt; 'GMC')
  #other processing
  @car.update_attributes(:model =&gt; 'Sierra', :year =&gt; &quot;2012&quot;, :looks =&gt; &quot;Super Sexy, wanna make love to it&quot;)
  #other processing
  @car.save
  </code></pre>
  <p>BTW, I know I can <code>@car.model = 'Sierra'</code>, but I want to update them all on one line.</p>
