How to read ruby on rails config values from within the application controller

Question

If i have a configuration file like this

# config/environments/integration.rb config.action_controller.session = {   :domain => ".example.com" } 

How do I get the value from within my application controller, e.g:

# app/controller/application_controller class ApplicationController < Mcc::CoreSupport::FrontendController   def some_method     value = xxx   end end 

Answer 1

In Ruby on Rails 3 and above, you can access the config through Rails.application.config

---

In more recent versions, you can use Rails.configuration instead. For example: Rails.configuration.time_zone. See more in the official manual on configuration

Answer 2

The class method ActionController::Base.session_options returns a hash of the configuration options for the session.

So in your case you want ActionController::Base.session_options[:domain]
