Module: Ditty::Services::Settings

Defined in:
lib/ditty/services/settings.rb

Overview

This is the central settings service Ditty. It is used to get the settings for various aspects of Ditty, and can also be used to configure your own application.

It has the concept of sections which can either be included in the main settings.yml file, or as separate files in the ‘config` folder. The values in separate files will be used in preference of those in the `settings.yml` file.
