I was wondering how to add custom configuration variables to a rails application and how to access them in the controller, for e.g I want to be able to define an upload_directory in the configuration files say development.rb and be able to access it in one of my controllers.
Secondly I was planning to have S3 support for uploads in my application, if I wanted to add a yaml file with the s3 access, secret key, how do I initialize it in my Rails App and how do I access the values that I have defined in that config file.
