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
Archive
on your ActiveRecord model.
CopyMyModel.none # returns an empty ActiveRecord::Relation object
For older Rails versions you can use the attached initializer to get a none scope.
By refactoring problematic code and creating automated tests, makandra can vastly improve the maintainability of your Rails application.
