How to set environment variables in heroku-django project?

问题

I have this code in my settings.py..

EMAIL_HOST = 'smtp.sendgrid.net'
EMAIL_HOST_USER = os.environ.get('EMAIL_HOST_USER')
EMAIL_HOST_PASSWORD = os.environ.get('EMAIL_HOST_PASSWORD')

I tried setting environment variable using this in heroku bash

export EMAIL_HOST_USER=xxx

and also

heroku config:set EMAIL_HOST_USER=xxx

None of the both method worked for me. How can i set environment variable in heroku?

回答1:

okk.. found the answer!!

instead of

heroku config:set EMAIL_HOST_USER=xxx

writing

heroku config:add EMAIL_HOST_USER=xxx

solves problem..
