title: Tables not showing up and migrations not visible after `python manage.py migrate`
body: <p>I'm following the official tutorial on Django and have run <code>python manage.py migrate</code> in <a href="https://docs.djangoproject.com/en/1.11/intro/tutorial02/" rel="nofollow noreferrer">https://docs.djangoproject.com/en/1.11/intro/tutorial02/</a> . After this, I'd expect some files to show up in polls/migrations, but there is just an empty <code>__init__.py</code> there, and when I run <code>sqlite3</code> and type <code>.tables</code> or <code>.schema</code>, nothing is output. Still, the <code>python manage.py migrate</code> command seems successful:</p>
  
  <pre><code>$ python manage.py migrate
  Operations to perform:
    Apply all migrations: admin, auth, contenttypes, sessions
  Running migrations:
    Applying contenttypes.0001_initial... OK
    Applying auth.0001_initial... OK
    Applying admin.0001_initial... OK
    Applying admin.0002_logentry_remove_auto_add... OK
    Applying contenttypes.0002_remove_content_type_name... OK
    Applying auth.0002_alter_permission_name_max_length... OK
    Applying auth.0003_alter_user_email_max_length... OK
    Applying auth.0004_alter_user_username_opts... OK
    Applying auth.0005_alter_user_last_login_null... OK
    Applying auth.0006_require_contenttypes_0002... OK
    Applying auth.0007_alter_validators_add_error_messages... OK
    Applying auth.0008_alter_user_username_max_length... OK
    Applying sessions.0001_initial... OK
  </code></pre>
  
  <p>What's going wrong here?</p>
  
  <p>EDIT: </p>
  
  <p>Added <code>'polls',</code> to my <code>INSTALLED_APPS</code>. Then:</p>
  
  <pre><code>$ python manage.py makemigrations
  Migrations for 'polls':
    polls/migrations/0001_initial.py
      - Create model Choice
      - Create model Question
      - Add field question to choice

  Enter ".help" for usage hints.

  Use ".open FILENAME" to reopen on a persistent database.

  <p>Same problem.</p>
  
  <p>EDIT2: Upon running <code>python manage.py dbshell</code>, <code>.schema</code> and <code>.tables</code> finally produced output. </p>
