Instance Method Details
#transform_values {|Object| ... } ⇒ Hash, Enumerator
Note:
This will be run in CI on Ruby 2.3, but we only collect coverage from current Ruby
Rails <= 5.2 had a transform_values method, which was added to Ruby in version 2.4.
This method is a backport of that original Rails method for Ruby 2.2 and 2.3.
