After upgrading our application from Rails 2.3.2 to 2.3.4 all our error messages appeared as "{{attribute}} {{message}}" (literally). Since we noticed this problem short before a release and hadn''t enough time to look deeper into it we fixed it by using the "old" full_messages method that was present in 2.3.2 So today I started reading up on what exactly has changed, but currently I''ve hit the wall and have no idea what it was. I''ve read a couple of bug reports and looked at the commits but I couldn''t make anything out of it. Our applications uses I18n and I know the recent changes might have something to do with that. Is there anybody that could explain to me what has changed between 2.3.2 and 2.3.4 concerning error messages on your models? We could go with the "fix" we have now, but I really would like to understand the changes and do it the "right" way. We are using Rails for a reason after all.. Thanks a lot, Jeroen redstorm.be
