Is there any way to get the exception

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?

morderlist.errors
