body: <p>I am using python-social-auth. But when I run makemigrations and migrate. The tables "social_auth-*" are not created.</p>
  
  <p>My settings.py looks like this</p>
  
  <pre><code>INSTALLED_APPS += (
      'social.apps.django_app.default',
  )
  AUTHENTICATION_BACKENDS += (

      'social.backends.twitter.TwitterOAuth',
  )
  
  SOCIAL_AUTH_USER_MODEL = AUTH_USER_MODEL
  
  # Rausnehmen wenns Probleme mit der Auth. gibt
  
  SOCIAL_AUTH_PIPELINE = (
      'social.pipeline.social_auth.social_details',
