sorry to bother to help me again.I invoke create action using ajax.The
variant and it's associations are put in a transaction.When both are
saved successfully,render create_variant using ajax.When anyone
unsuccessfully,rallback all the saving manipulation,rescue exception,and
render the new_variant using ajax,which has <%=error_messages_for
:variant-%> to display invalidations.
But when inputtings are invalid,i always get something like
attachment.It seems the exception is not handled at all,the error
meassages are not displayed as expected.can you help me? thank!

def create
@product=Product.find_by_id(params[:product_id])
@variant=Variant.new(params[:variant])
@product.variants<<@variant
@base_option=Option.new(:name=>params[:base_option][:name],:price=>0)
@variant.options<<@base_option
Variant.transaction do
begin
@variant.options.each{|option|option.save!}
@variant.save!
flash.now[:notice]='variant created successfully'
render :action=>:create_variant,:layout=>false
