Ruby on Rails Configuration Environments in Rails


Example

Configuration files for rails can be found in config/environments/. By default rails has 3 environments, development, production and test. By editing each file you are editing the configuration for that environment only.

Rails also has a configuration file in config/application.rb. This is a common configuration file as any settings defined here are overwritten by the config specified in each environment.

You add or modify configuration options within the Rails.application.configure do block and configuration options start with config.
