#method_missing

Constructor Details

#initialize(hash_or_file = self.class.source) ⇒ Settingslogic

Initializes a new settings object. You can initialize an object in any of the following ways:

Settings.new(:application) # will look for config/application.yml
Settings.new("application.yaml") # will look for application.yaml
Settings.new("/var/configs/application.yml") # will look for /var/configs/application.yml
Settings.new(:config1 => 1, :config2 => 2)

Basically if you pass a symbol it will look for that file in the configs directory of your rails app, if you are using this in rails. If you pass a string it should be an absolute path to your settings file. Then you can pass a hash, and it just allows you to access the hash via methods.
