Thanks Fred. Considering there is a bit of "wizardry" that needs to be done and that Rails doesn't include helpers to do this simply, does it mean it is not recommended to build such complex forms?
I am not very experienced with Rails, but I love the fact it is very "clean" and I feel a bit cautious having to generate keys manually.
