  • how do i set up a grails environment variable

    - by TripWired
    I'm uploading images in a grails app I'm developing and I want to be able to have an environment variable the determines where these images are.

I'm assuming i can set up my config.groovy with the variables i'm just not sure how i switch between them or use them in code.
