Accessing config from application.rb in Controller (Rails 3)

Question

I\'m trying to add two extra config options to my application.rb so I can read them out in controllers.

# Extra
config.twitter.key = \'foo\'
config.twitter.s

I've tried this and seems to be working, you can use ::Rails.application.config.

For example I'm using it to get the correct time_zone set in the application like this:

Rails.application.config.time_zone

I found it thanks to the less-rails code: https://github.com/metaskills/less-rails/blob/master/lib/less/rails/helpers.rb

So you can declare this in your application.rb or in any enviroment file:

config.twitter_key = 'foo'

And then read it like so anywhere in your code:

Rails.application.config.twitter_key
