It makes sense to me, you get passed a hash with the attributes to update, which could be none.
This is a no-op edge-case similar to append an empty list to a list, etc., and could have use cases where the hash is built programatically. The implementation generally uses iterators, which is the normal way to support these edge-cases with no explicit handling, maybe the exception is raised by update_all(attributes) https://github.com/rails/rails/blob/master/activerecord/lib/active_record/persistence.rb#L312 ? -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Core" group.
