Returning an empty ActiveRecord scope

Returning an empty scope can come in handy, e.g. as a default object. In Rails 4 you can achieve this by calling none on your ActiveRecord model.

MyModel.none # returns an empty ActiveRecord::Relation object

For older Rails versions you can use the attached initializer to get a none scope.

Once an application no longer requires constant development, it needs periodic maintenance for stable and secure operation. makandra offers monthly maintenance contracts that let you focus on your business while we make sure the lights stay on.
