Let’s talk about comparing elements in an array. As it is, the map{} is already somewhat irrelevant to the test and adding clutter, I’d prefer to not add even more. Well, that … Read more
Assuming the staging environment, as your example points to. You’ll want to load the console by prepending the RAILS_ENV environment variable to the rails console command. RAILS_ENV=staging rails console That should get you in. Once you’re in, you can just access the ENV variable directly. 2.2.2 (main):0 > ENV And that will dump out the … Read more
