Module Waves::Layers::ORM::Sequel
In: lib/layers/orm/providers/sequel.rb

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.

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

Public Class methods

included(app)

On inclusion, this module:

  • creates on the application module a database method that establishes the Sequel connection
  • arranges for autoloading/autocreation of missing constants in the Models namespace
  • defines Sequel-specific helper methods on Waves::Controllers::Base

The controller helper methdods are:

  • all
  • find(name)
  • create
  • delete(name)
  • update(name)
