How to properly runserver on different settings for Django?

Question

I have a basic django rest API. I want to separate some of my settings for dev and prod just for organizational purposes. I\'m also just learning about separating environments.

Answer 1

For example I open SQL log in dev settings

1. My file structure:
   create settings folder and mv original settings.py to settings/defaults.py

2. load defaults in init.py

# proj/proj/settings/__init__.py

from .defaults import *

3. Edit dev.py

# proj/proj/settings/dev.py

from .defaults import *
DEBUG = True

# print sql to the console
LOGGING = {
    'version': 1,
    'disable_existing_loggers': False,
    'handlers': {
        'console': {
            'class': 'logging.StreamHandler',
        }
    },
    'loggers': {
        'django.db.backends': {
            'handlers': ['console'],
            'propagate': True,
            'level': 'DEBUG',
        }
    },
}

4. run in the python env

./manage.py runserver --settings proj.settings.dev
