From 817c1825c15013fd0180762ac5c05a2e024a640d Mon Sep 17 00:00:00 2001 From: yui-knk Date: Sun, 15 Nov 2015 23:56:52 +0900 Subject: Except keys of `build_record`'s argument from `create_scope` in initialize_attributes If argument of `build_record` has key and value which is same as default value of database, we should also except the key from `create_scope` in `initialize_attributes`. Because at first `build_record` initialize record object with argument of `build_record`, then assign attributes derived from Association's scope. In this case `record.changed` does not include the key, which value is same as default value of database, so we should add the key to except list.
