@sakshi1499 Can I try this.

[theyashshahs]

@saideepesh000 go for it 👍

[saideepesh000]

@yashshah2820 @sakshi1499, For now, what should I keep in the .env file

[theyashshahs]

@saideepesh000 you can use the env variables used in the README like SECRET_KEY='foobarbaz' and the env variables in base.py and dev.py 😃

[saideepesh000]

@yashshah2820 Ok, what should I keep the database password in env. And a small doubt, why are we not updating production.py with python-decouple, because that's going to be on the hosted part.

@saideepesh000 it's all in the README
