title: multiple databases and multiple models in django
body: <p>I have two databases and two models:the Admin and the user.</p>
  
  <p>I want to sync my models to the two databases;
  admin model to database A and user model to database B;</p>
  
  <p>If I am setting the model path to <code>INSTALLED_APPS</code> and <code>syncdb</code>, the two models will sync to the default database.</p>
  
  <p>if I set the database in the <code>syncdb</code> command such as <code>sync --database="B"</code>, and the two models will sync to database B.</p>
  
  <p>So my problem is, how do I sync the two models to two databases?</p>
