Excellent, that (expire, refresh) works. Thank-you very much.
Is there a reason why it sometimes works?

oh sorry, i missed this one. when you say "r.cancelled_user_id =
u.id", that will send the right SQL to the database but isnt going to
change the "r.cancelled_user" property to anything unless you refresh
