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
rescue Exception
raise
render :action=>:new_variant,:layout=>false

I tested using non-ajax call,but the problem was same,the exception was not handled like the attachment and new_variant template was not rendered as expected.The render should not be used in the rescue block? can you help me? -- Posted via http://www.ruby-forum.com/. -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
