How to define environment variable in Looker

[pratlooker]

I have looker project which needs to be deployed in Dev, QA & Prod. I need to define environment specific constants. when code runs in dev it should check for date < 7. After the code deployed in QA, when the code runs in QA it should check for the date < 15. Same with Prod.

My question after the deployment I should not change the code but it should pick up these from environment variable. Can we use Manifest / User Attributes?

One more: Is there any way to know which environment the code runs currently?

You can use manifest file for this
