title: Utility of managed=False option in Django models
body: <p>In django models we have option named <strong>managed</strong> which can be set <code>True</code> or <code>False</code></p>
  <p>According to documentation the only difference this option makes is whether table will be managed by django or not. Is management by django or by us makes any difference?</p>
  <p>Is there any pros and cons of using one option rather than other?</p>
  <p>I mean why would we opt for <code>managed=False</code>? Will it give some extra control or power which affects my code?</p>
