"""Dynaconf django extension
|
|
|
|
In the `django_project/settings.py` put at the very bottom of the file:
|
|
|
|
# HERE STARTS DYNACONF EXTENSION LOAD (Keep at the very bottom of settings.py)
|
|
# Read more at https://www.dynaconf.com/django/
|
|
import dynaconf # noqa
|
|
settings = dynaconf.DjangoDynaconf(__name__) # noqa
|
|
# HERE ENDS DYNACONF EXTENSION LOAD (No more code below this line)
|
|
|
|
Now in the root of your Django project
|
|
(the same folder where manage.py is located)
|
|
|
|
Put your config files `settings.{py|yaml|toml|ini|json}`
|
|
and or `.secrets.{py|yaml|toml|ini|json}`
|
|
|
|
On your projects root folder now you can start as::
|
|
|
|
DJANGO_DEBUG='false' \
|
|
DJANGO_ALLOWED_HOSTS='["localhost"]' \
|
|
python manage.py runserver
