title: How do I clone a Django model instance object and save it to the database?
body: <pre><code>Foo.objects.get(pk="foo")
  &lt;Foo: test&gt;
  </code></pre>
  
  <p>In the database, I want to add another object which is a copy of the object above.</p>
  
  <p>Suppose my table has one row. I want to insert the first row object into another row with a different primary key. How can I do that?</p>
