For Rails, how to access or print out config variables (as experiment or test / debugging)

Question

For example, in config/environments/production.rb in a Rails 3 app, there is

config.serve_static_assets = false

and many variables

Answer 1

Like idlefingers pointed out, for newer versions of rails, Rails.application.config.my_variable should get you what you're looking for.

However, if that doesn't work because you're stuck with an older version of Rails (2.3, etc) you can use the ENV constant, like so: ENV['my_variable']
