Hi All, If you have a has_many association without a defined order on a model and call a method on it through the method_missing method (for example a scope) and then call last on that you''ll get an error. To concretize a bit: Person.posts.active.last NoMethodError: private method `split'' called for nil:NilClass from ./../frontend/vendor/rails/activerecord/lib/active_record/ base.rb:1540:in `reverse_sql_order'' from ./../frontend/vendor/rails/activerecord/lib/active_record/ base.rb:1529:in `find_last'' from ./../frontend/vendor/rails/activerecord/lib/active_record/ base.rb:614:in `find'' from ./../frontend/vendor/rails/activerecord/lib/active_record/ base.rb:1907:in `find_last_by_credits'' from ./../frontend/vendor/rails/activerecord/lib/active_record/ base.rb:1892:in `send'' from ./../frontend/vendor/rails/activerecord/lib/active_record/ base.rb:1892:in `method_missing'' from ./../frontend/vendor/rails/activerecord/lib/active_record/ associations/association_collection.rb:374:in `send'' from ./../frontend/vendor/rails/activerecord/lib/active_record/ associations/association_collection.rb:374:in `method_missing'' from ./../frontend/vendor/rails/activerecord/lib/active_record/ base.rb:2148:in `with_scope'' from ./../frontend/vendor/rails/activerecord/lib/active_record/ associations/association_proxy.rb:206:in `send'' from ./../frontend/vendor/rails/activerecord/lib/active_record/ associations/association_proxy.rb:206:in `with_scope'' from ./../frontend/vendor/rails/activerecord/lib/active_record/ associations/association_collection.rb:370:in `method_missing'' from (irb):5 I have submitted a patch to lighthouse for this bug.
