instance method
test_to_key
Ruby on Rails 5.1.7
Since v3.0.20Signature
test_to_key()Passes if the object’s model responds to to_key and if calling this method returns nil when the object is not persisted. Fails otherwise.
to_key returns an Enumerable of all (primary) key attributes of the model, and is used to a generate unique DOM id for the object.
