Array#sum was added in Ruby 2.4, hence the behavior change you are seeing.
You can pass a block to the association_proxies plugin for control over whether the methods sent to the proxy are forwarded to the array of associated objects (block returns false or nil) or the association dataset (otherwise). See the association_proxies plugin documentation for details. Thanks, Jeremy -- You received this message because you are subscribed to the Google Groups "sequel-talk" group.
