Constructor Details

#initialize(model_class, model_definition, filter: :all) ⇒ AssociationApplicator

‘filter` controls which associations the applicator iterates:

:all (default) — every YAML association (current behavior, used by
  ModelFactory::Builder for dynamic LCP models).
:managed       — only associations marked `lcp_managed: true`,
  used by Engine.apply_bind_to_managed_associations to declare AR
  macros on bind_to: host classes. Suppresses
  accepts_nested_attributes_for so LCP does not silently install
  <assoc>_attributes= writers that may collide with host-defined
  attribute writers — host opts in by writing it themselves.
