title: Django manually select multiple databases
body: <p>Well, after reading the doc <a href="https://docs.djangoproject.com/en/1.6/topics/db/multi-db/" rel="nofollow">https://docs.djangoproject.com/en/1.6/topics/db/multi-db/</a></p>
  
  <p>I understand the way that developer can manually select database for selecting, saving and deleting. My question is that is there a more easy way for doing that?</p>
  
  <p>I mean does django have something like its transaction management? </p>
  
  <pre><code>with transaction.atomic():
      do_something()
  </code></pre>
  
  <p>So all the code under a particular section are in one transaction that talking to one particular database, like</p>
  
  <pre><code>with using(default):
      do_something()
  </code></pre>
  
  <p>If django doesn't have this kind of wrapper, is there any good way to achieve what I described?</p>
