Question

I have a typical model setup:

Store has_many Items
Orders has_many Items :through OrderItems
OrderItems

However, on the OrderItems I have a field called “quantity” to tell me how many of each item is on the order. I can’t figure out how to properly retrieve this information.

ex. Order.find(1).order_items # has the list of items, but no "quantity" field

Any thoughts?

Answer 1

I had the same situation.I had used another association for this.Like

Store has_many Items
Orders has_many Items :through OrderItems
Orders has_many OrderItems

It will use the same order_id to map and then

Order.find(1).order_items # has the list of order_items, with "quantity" field in there
