Config in rails

For general application configuration that doesn't need to be stored in a database table, I like to create a config.yml file within the config directory. For your example, it might look like this:

defaults: &defaults

  audiocast_uri_format: http://blablalba/blabbitybla/yadda

development:

  <<: *defaults

test:

  <<: *defaults

production:

  <<: *defaults

This configuration file gets loaded from a custom initializer in config/initializers:

APP_CONFIG = YAML.load_file("#{RAILS_ROOT}/config/config.yml")[RAILS_ENV]

You can then retrieve the value using:

uri_format = APP_CONFIG['audiocast_uri_format']
