Move the settings.py to settings folder and rename as base.py

And create the following new files for development/production environments.

1. dev.py
2. prod.py

Move the follwoing settings to dev.py and prod.py.

• SECRET_KEY = '!&r6$4bw+yhf6_+z0bfay%t%s051e=!*0kii0+dev_5!wwea46'
• DEBUG = True
• ALLOWED_HOSTS = ['*']

*dev.py

SECRET_KEY = 'XXXXXXXX'
DEBUG = True
ALLOWED_HOSTS = ['*']

*prod.py

SECRET_KEY = 'yyyyyyyyyy'
DEBUG = False
ALLOWED_HOSTS = ['localhost', '127.0.0.1']

Notice that when DEBUG is disabled, the ALLOWED_HOSTS is required.

While we move the settings file to /settings, we have to modify the BASE_DIR as following.

BASE_DIR = os.path.dirname(os.path.dirname(os.path.dirname(__file__)))

$ python manage.py migrate auth

• Original

MIDDLEWARE = [
    'django.middleware.security.SecurityMiddleware',
    'django.contrib.sessions.middleware.SessionMiddleware',
    #...
]

• After update

MIDDLEWARE_CLASSES = [
    'django.middleware.security.SecurityMiddleware',
    'django.contrib.sessions.middleware.SessionMiddleware',
    #...
]

$ python manage.py createsuperuser

1. WSGIRequest object has no attribute 'user' Django admin

• Error message

"WSGIRequest" object has no attribute 'user' Django admin

Go to settings.py and replace MIDDLEWARE=[...] with MIDDLEWARE_CLASSES=[...].
