Class Method Details

.add_extensions(*modules) ⇒ Object

Add one or more extension modules to the receiving class. This allows subsystems like Orders, etc. to decorate models outside of their purview without introducing unnecessary dependencies.

Each one of the given modules will be included in the receiving model class, and if it also contains a constant called ClassMethods, the model class will be also be extended with it.

Examples:

Add order methods to Webhookdb::Customer


module Webhookdb::Orders::CustomerExtensions

    # Add some associations for Order models
    def included( model )
        super
        model.one_to_many :orders, Sequel[:app][:orders]
    end

    def first_order
        self.orders.first
    end

end
