Django | Set up environment variables in Django
1. Install Django Environ
In your terminal, inside the project directory, type:
$ pip install django-environ
2. Import environ in settings.py
import environ
3. Initialise environ
Below is your import in settings.py:
import environ # Initialise environment variables env = environ.Env() environ.Env.read_env()
4. Create your .env file
In the same directory as settings.py, create a file called ‘.env’
5. Declare your environment variables in .env
Make sure you don’t use quotations around strings.
SECRET_KEY=h^z13$qr_s_wd65@gnj7a=xs7t05$w7q8!x_8zsld# DATABASE_NAME=postgresdatabase DATABASE_USER=alice DATABASE_PASS=supersecretpassword
6. Replace all references to your environment variables in settings.py
DATABASES = {
‘default’: {
‘ENGINE’: ‘django.db.backends.postgresql_psycopg2’,
‘NAME’: env(‘DATABASE_NAME’),
‘USER’: env(‘DATABASE_USER’),
‘PASSWORD’: env(‘DATABASE_PASS’),
}
}
And
SECRET_KEY = env(‘SECRET_KEY’)
