I think your problem is in the way you've used the AR relationships in constructing the form you have there. Your form is using the has-many-through relationship from Delivery to Product to construct the form. This was all right before you had anything meaningful at the DeliveryItem level, but now the whole form needs to be reworked to stop thinking of Delivery as a bunch of Products and instead as a number of DeliveryItems, each of which is associated with a Product.
I haven't had to do anything like this before, but I would try to solve it as follows: 1. Add an *accepts_nested_attributes_for* call to Delivery for :delivery_items. 2. Add a quantity attribute to DeliveryItem 3. Change the form from a single select with a list of Products to a number of rows, each with a single-item select for Product and a text field for entering quantity.
