title: What is a "Manager" in django?
body: <p>I have read the definition in the official Django <a href="https://docs.djangoproject.com/en/dev/topics/db/managers/" rel="noreferrer">documentation</a>, and I am still confused by what a <code>Manager</code> does.</p>
  <p>The documentation says that they allow you to operate on database tables/models, but I still don't understand this.</p>
  <p>Can someone explain managers and their role to me? An answer with an example would be preferable.</p>
