Isn't that where it would be best?

but of course, we all know that relying solely on JS for validation is
a sure method for letting duff data get into your DB (because not
every browser has JS enabled or supported)
By all means, use the JS to enhance the front end; but if you have to
ensure there's no more than a certain amount of associations, you
*have* to check that in the model.
You could also check the params array coming into the controller, and
see what the size is there (unfortunately, I don't have time right
this second to try it out, but if you haven't sorted it yourself
later, re-post for help and I'll have a play)
