* allow the relationship's serializer key to be a Proc * fixes * specifically test the relationship name and the resource type * support object blocks without a serializer defined * stop validation gracefully if the relationship is polymorphic * improve performance by using instance variables instead of accessor methods * force initialization up front to avoid the iterative calls * serializer procs should act like polymorphic when determining the id_method_name * specs for serializer procs * updated with more details and examples for relationship serializer options * adjust specs to define the serializers * avoid extra method calls for performance * name change * one less function call for better performance * do not require lazy loaded relationships to resolve the serializer * give polymorphic precedence for backwards compatibility * move serializer inference into ObjectSerializer to allow for overriding * move method for better diff * fix race condition in multi-threaded environments
