Hi all,
I have tested the method changes in ActiveModel::Dirty but it doesn't return any result.
In my ActiveRecord object I call it as documented:
person.changes
but it returned null
But when I call other methods in the ActiveModel::Dirty module such as `changed` and `changed?`, it returns value(s).
Has the method `changes` been implemented, or do I call the method wrongly?
Kind regards, Joshua
