ciao \*,  
da un oggetto activerecord, invocando il metodo .destroy, è  
possibile eliminare anche tutti i figli (ricorsivamente) di tale  
oggetto?  
cioè, ad esempio, avendo  
A:  
has\_many B

B:  
belongs\_to A  
has\_many C

C:  
belongs\_to B

io vorrei un qualcosa del genere  
a=A.find(:first)  
a.destroy che mi elimini anche tutti i B figli di a, e i C figli dei  
B figli di a.

è possibile fare ciò, senza usare le FK (on delete cascade) del db?

grazie,  
stefano
