Setting up environmental variables in Python

Long time creeper, first time caller. I was trying to create and use environ var to send gmail (smtp) from a settings.py file, but clearly I was doing it wrong because when I put in my password it worked, but when I used os.environ.get to hide the password.

I think I didn't call the environmental variable correctly but I have no clue! I got an authentication error

import os

EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'
EMAIL_HOST = 'smtp.gmail.com'
EMAIL_PORT = 587
EMAIL_USE_TLS = True
EMAIL_HOST_USER = '[email protected]'
EMAIL_HOST_PASSWORD = 'Thisworkedfine'

But when I used this it didn't work after defining 'EMAIL_USER' and 'EMAIL_PASS' in my System Properties. 


EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'
EMAIL_HOST = 'smtp.gmail.com'
EMAIL_PORT = 587
EMAIL_USE_TLS = True
EMAIL_HOST_USER = os.environ.get('EMAIL_USER')
EMAIL_HOST_PASSWORD = os.environ.get('EMAIL_PASS')

Error from hell:

SMTPSenderRefused at /password-reset/
(530, b'5.5.1 Authentication Required. Learn more at\n5.5.1  https://support.google.com/mail/?p=WantAuthError c2sm2597974pjs.13 - gsmtp', 'webmaster@localhost')

HALP!

In another file (something like envvar.py) create two variables. One for email and one for password:

email = "[email protected]"
password = "somepassword"

then in your settings file:

import envvar

EMAIL_HOST_USER = envvar.email
EMAIL_HOST_PASSWORD = envvar.password

Then add envvar to your gitignore

I highly recommend using dotenv module for python, I personally found this to be the most hassle free way to deal with environment variables.

Chuck all your evnironment variables in a .env file which is just key value pairs. So the content of your .env file would look something like this:

EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'
EMAIL_HOST = 'smtp.gmail.com'
EMAIL_PORT = 587
EMAIL_USE_TLS = True
EMAIL_HOST_USER = '[email protected]'
EMAIL_HOST_PASSWORD = 'Thisworkedfine'

Then you in whichever python file you want to use your envars you can do this:

import os
from dotenv import load_dotenv

EMAIL_BACKEND = os.getenv('EMAIL_BACKEND')

Then just make sure to include your .env in your .gitignore so that your secrets always stay local.

for more info check out the dotenv github repo here

One way is to set your variables in another python file and import the file.

Create a file say,myEnvVal.py

import os
# Set environment variables
def setVar():
    os.environ['EMAIL_USER'] = '[email protected]'
    os.environ['EMAIL_PASSWORD'] = 'Thisworkedfine'

Now import this file 

import os
import myEnvVal
myEnvVal.setVar()
EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'
EMAIL_HOST = 'smtp.gmail.com'
EMAIL_PORT = 587
EMAIL_USE_TLS = True
EMAIL_HOST_USER = os.environ.get('EMAIL_USER')
EMAIL_HOST_PASSWORD = os.environ.get('EMAIL_PASS')
