▌Environment

---

▋Python 3.6.2

▋Django 1.11.5

▌Implement

---

First, create a new folder named settings and move the settings.py to it and rename settings.py to base.py.

Also create the following files,

1.  __init__.py

2.  dev.py

3.  prod.py

 

▋Update the BASE_DIR

▋base.py

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

▋Settings by different environment

Move these settings from base.py to both dev.py and prod.py

 SECRET_KEY = 'XXXXXXXXXXXXXXXX'

 DEBUG = True

 ALLOWED_HOSTS = []

▋dev.py

 from .base import *

 SECRET_KEY = 'XXXXXXXXXXXXX'

 DEBUG = True

 ALLOWED_HOSTS = ['*']

▋prod.py

 from .base import *

 SECRET_KEY = 'XXXXXXXXXXXXXXXX'

 DEBUG = False

 ALLOWED_HOSTS = ['localhost', '127.0.0.1']

PS. The allowed hosts must be updated when deploying to production.

▋Run django with different settings

Open manage.py and change the default DJANGO_SETTINGS_MODULE.

 os.environ.setdefault("DJANGO_SETTINGS_MODULE", "venv.settings.dev")

Where venv is your virtualenv name.

Or you can change directly by the following command.

$  export DJANGO_SETTINGS_MODULE"="venv.settings.dev"

After start the application, the specified settings is used.
