#new_record? ⇒ Boolean
Use inverted form of #persisted?
Returns true if a remote resource has not been assigned an identity.
This was added for a ActiveRecord like feel but has been outdated by ActiveModel API using #persisted?

#persisted? ⇒ Boolean
Returns true if a remote resource has been assigned an identity and we can assume it has been persisted.
