You said in your first post that it *didn't* work trying to do a :though on a :has_one. So as far as I can see you have three choices: 1) Fudge it with a :has_many that you manually check only has one associated - messy, as Marnen pointed out. 2) Add the method I suggested to do the collect yourself (I default to using .inject, which is quite verbose... you could do the same thing with .map, which would remove the references to 'memo'). If the functionality *was* in Rails, it would be doing something similar in the background... 3) Patch Rails yourself to support going through a :has_one - look at the source of :has_many and see what it's missing. Personally, I'd do what I suggested (well, I would wouldn't I! ;-) as you can't expect the framework to do *everything* for you, and helpers like :through only come about when loads of people need to do the same thing frequently. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
