any and none

Anthon_Mur · October 12, 2015, 5:21pm

Hello. My question is about the methods mentioned in the subject.

[fact] Rails mixes in any? and none? from Enumerable.
[fact] Rails overrides any? to use nice feature of testing with COUNT query. rails/relation.rb at a419a4d9ade48e777166ff956dd7bb24e37b2181 · rails/rails · GitHub
[problem] Rails does not override none? method, instead it relies on empty?.

Why not alias none? to empty?

none? is currently overridden


      
          def none?
            return super if block_given?
            empty?
          end

On the other hand, none? cannot be aliased to empty? because empty? does not accept an optional block.
