title: Question about batch save objects in Django
body: <p>I haven't seen any thing on this topic in Django's online documents. </p>
  
  <p>I am trying to save a list of objects to database, but what I can do is loop through the list and call save() on every object. </p>
  
  <p>So does Django hit database several times? Or Django will do one batch save instead?  </p>
