Here is tow model:

class Morder \< ActiveRecord::Base  
has\_many :morderlists  
end

class Morderlist \< ActiveRecord::Base  
belongs\_to :morder

def validate  
#some validate  
end  
end

And the method in controller :

class MorderController \< ApplicationController  
def create  
morder=Morder.new(:code=\>‘001’)  
morderlist1=Morderlist.new  
morderlist2=Morderlist.new  
morder.morderlists \<\< [morderlist1,morderlist2]  
morder.save!  
end  
end

If the morderlist1 or morderlist2 is not correct,I just get the errors  
like 'morderlist invalid".Is there any way to get the detail  
information?
