From 0991c4c6fc0c04764f34c6b65a42adce190440c3 Mon Sep 17 00:00:00 2001 From: Sean Griffin Date: Thu, 12 May 2016 22:19:17 -0400 Subject: Give more context from `AssociationMismatchError` The error message that we give today makes this error difficult to debug if you receive it. I have no clue why we're printing the object ID of the class (the commit doesn't give context), but I've left it as it was deliberate. --- activerecord/lib/active_record/associations/association.rb | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) (limited to 'activerecord/lib') diff --git a/activerecord/lib/active_record/associations/association.rb b/activerecord/lib/active_record/associations/association.rb index f7edfbfb5f..62e867a353 100644 --- a/activerecord/lib/active_record/associations/association.rb +++ b/activerecord/lib/active_record/associations/association.rb @@ -217,7 +217,8 @@ module ActiveRecord unless record.is_a?(reflection.klass) fresh_class = reflection.class_name.safe_constantize unless fresh_class && record.is_a?(fresh_class) - message = "#{reflection.class_name}(##{reflection.klass.object_id}) expected, got #{record.class}(##{record.class.object_id})" + message = "#{reflection.class_name}(##{reflection.klass.object_id}) expected, "\ + "got #{record.inspect} which is an instance of #{record.class}(##{record.class.object_id})" raise ActiveRecord::AssociationTypeMismatch, message end end -- cgit v1.2.3
