title: django, difference between _base_manager and objects
body: <p>django internal code uses <code>_base_manager</code> instead of <code>objects</code></p>
  
  <p>There is also <code>_default_manager</code></p>
  
  <p>I'm more accustomed to using <code>objects</code></p>
  
  <p>What's the difference?</p>
