...> "Something Else" ).save i.save Fine, now I have two records in the items_things table. Now if I say t = Thing.find_by_value ''Something'' i.things.delete t i.save Then I have only one record in the items_things table. Which is correct.

If so, where''s the best place to report it? bye John

When I try this in irb the second statement works but the first does not and does not give any error messages. What...
