#source(filename, options = {}) ⇒ Object

a name of the file to read as it’s argument. We can also pass in some options, but at the moment it’s being used to allow per-environment overrides in Rails

Example Load without environment

Load with environment

> Settings.load!(

"#{Rails.root}/config/appdata/env-example.yml",
:env => Rails.env)
