Module: Tdc::Generators::DefinitionSourcable

Extended by:
ActiveSupport::Concern
Included in:
StandardGenerator
Defined in:
lib/tdc/generators/definition_sourcable.rb

Overview

Creates ghost methods for use in generators.

All ghost methods are named ‘key’_definition or ‘key’_definition_optional where ‘key’ is a key into the instance_definition hash.

Choose optional if the key may not be present in the instance_definition.

Example:

If an instance definition had “line” and “replenishment_parameters” keys then the following ghost methods could be used to refer to the value associated with those keys:

line_definition
line_definition_optional
replenishment_parameters_definition
