We have 2 models:
- Order
- OrderItems
So when saving the related OrderItems I need to check some attributes from the parent Order.
Order has attributes: "time_begin" and "time_end" and OrderItem has its own "time_begin" and "time_end". So the rule is that times of the OrderItem must be between times of the parent Order.
For example, I have the following situation:
- user changes the "time_end" of the Order to the bigger value and changes the "time_end" of OrderItem to bigger value too
- try to save all the related data (Order and all its Items)
- Order validations pass successfully
- but when the OrderItem trying to validate its "time_end", it takes the old value of Order->time_end property and gives an validation error!!!
Any solution??? How to let OrderItem to know that Order has changed?
