Ruby on Rails

Ok, thanks a lot !

But, these objects are not already saved in the database, so I can not
save the ids !

I have to check a lot of things before doing that.........a solution
could be to use transactions.
How can I rollback after have saved objects ?

One more time, thank you Frederick !
