Instance Method Details

#backend(backend, options = {}) ⇒ Object

Add a backend to load configuration from.

You can define several backends; they will all be loaded and the configuration hashes will be merged.

Configure with either:

Global.backend :filesystem, path: 'config', environment: Rails.env

or:

Global.backend YourConfigurationBackend.new

backend configuration classes MUST have a ‘load` method that returns a configuration Hash
