class Athena::ORM::Events::PreUpdateEventArgs(T)
inherits Athena::ORM::Events::LifecycleEventArgs

Emitted during AORM::EntityManager#flush for each managed entity with changes, right before its UPDATE.

Lifecycle callbacks annotated with AORMA::PreUpdate receive it. Changes they make to the entity's fields are written by the same UPDATE. Changes to collections aren't.

@[AORMA::Entity]
class Article < AORM::Entity
  # ...

  @[AORMA::PreUpdate]
  def set_updated_at : Nil
    @updated_at = Time.utc
  end
end

Todo

The event doesn't expose the entity's change set yet; AORM::UnitOfWork#entity_changeset returns it in the meantime.
