title: Django Tutorial - Writing your first Django app, part 2, I'm trying to migrate but it shows "No migrations to apply."
body: <p>I just started learning Django through the tutorial from Djangoproject.
  I'm trying to migrate but it shows "No migrations to apply" in terminal where it supposed to show "Applying polls.0001_initial... OK."
  And don't know where I made mistakes, could you please help?
  Thank you.</p>
