Question

There are certain variables I would like to have in the development environment, and certain variables for the production environment. For example, in production mode, I might want to use a cache to speed up performance. I have couple of open-ended questions about this:

Question: What is the easiest and fastest way to set environment variables in a rails app? For example, ENV["USE_CACHE"] = true in production, and = false in development.

If you could point to a specific gem, and/or the specific files I'd need to touch, that would be most helpful. Thanks!

I learnt few things about ENV variables this discussion

You can set ENV varaibles by just appending

export USE_CACHE=true

to your .bashrc file.

...and in your application you can use

ENV["USE_CACHE"]

, you can also check out figaro and dotenv which are application specific.

For your purpose just use

if Rails.env.eql?("development")
 #do stuff
end

Its upto you choose easiest and fastest way!
