Module: Waves::Layers::ORM::Sequel

Defined in:
lib/layers/orm/providers/sequel.rb

Overview

The Sequel ORM layer sets up the Sequel connection and configures AutoCode on Models, so that constants in that namespace get loaded from file or created as subclasses of Models::Default. The dataset for models is set to the snakecased version of the model’s class name.
