Module: Shared::BiologicalAssociations

Extended by:
ActiveSupport::Concern
Included in:
Otu
Defined in:
app/models/concerns/shared/biological_associations.rb

Overview

Shared code for extending data classes with an OriginRelationship

How to use this concern:
  1) In BOTH related models, Include this concern (`include Shared::OriginRelationship`)
  2) In the "old" model call "is_origin_for" with valid class names, as strings, e.g.:
     `is_origin_for 'CollectionObject', 'CollectionObject::BiologicalCollectionObject'`
  3) has_many :derived_<foo> associations are created for each is_origin_for()

  !! You must redundantly provide STI subclasses and parent classes if you want to allow both.  Providing
     a superclass does *not* provide the subclasses.
