Hello everyone
I have this model
class DetailPurchase < ActiveRecord::Base
belongs_to :purchase, :foreign_key => ''purchase_id''
belongs_to :product, :foreign_key => ''product_id''
belongs_to :buy_order_detail, :foreign_key =>
''buy_detail_id''
def before_create
Storage.create!(:product_id => self.product_id, :current_quantity
=> self.quantity, :stg_data => purchase.prc_data)
end
end
as you can see I''m using "before_create" callback. It was
working just
fine two weeks ago, but today I realize it wasn''t. I don''t
know why.
The only change is that now I''m using jquery instead of prototype

The callback is not working. When I call to "Storage.create!" it should create a new Storage, but now the storage is never create. Thanks for your help, I''ll try debugging.

If you assign the result of Storage.create! to a variable and break after that then you will be able to inspect that object. Have you got any validations on Storage that could prevent it from saving?

Add an extra line after the debugger statement (i=0 for example) to give it something to break on. On a separate issue, looking at the message you get, are you using ruby 1.9.1? If so then upgrade to 1.9.2 or go back to 1.8.7, ruby 1.9.1 does not work reliably with rails. This may have nothing to do with your problem.
