hi people I have something strange here, and I would like to share it with you, to find a solution or at least, different opinion. I have a rails 3.0.9 app. I''m trying to store historical data so I made the following. I have 3 tables "invoices", "purchases", "detail_purchases". I''m using "nested_attributes" (not nested form) in 2 levels deep (invoices builds purchases and then purchases builds detail_purchases). Due to this I have to use some callbacks, because I don''t have controllers for "purchases" nor "detail_purchases". In the historical table I store - user_id (user who made the change) - object_id (in this case, the id of the invoice, id of purchase, etc. depending on which one is changed or created) - class_name - action_name (create, update, destroy, etc.) - datetime so, when I create an invoice, the logic order should be: 1. create purchase 2. create detail_purchase 3. update purchase 4. create invoice but get the following, instead 1. update purchase 2. create detail_purchase 3. create purchase 4. create invoice I check datetime, the order is correct, the registers are stored in the database... but I still don''t understand how can I "update" something that is not yet created.
