title: Django redirect does not redirect
body: <p>I am a beginner with Django transaction I use this code to manage my transaction manually : </p>
  
  <pre><code>@transaction.commit_manually

  <p>All is Ok, but the redirect doesn't work when my data is saved, it always returns to the same page.</p>
