We are currently building an EC site and are creating a purchase history screen.
As shown in the orders table below, it is assumed that Mr. A (user_id = 1) will buy two products at one time.
If i purchase two or more products at once, I want to display them together in the view (a case often seen on Amazon etc.).

In the case of DB design column, those with ids 4,5,6 in the Orders_Products table are displayed together.
I want to display the one with id 7 separately from 4,5,6 (= purple part becomes two)

Items purchased at the same time as shown in the photo will also be displayed separately.
I want to display items purchased at the same time.

In the show action of controller
① Pull the record where user_id in the orders table is the logged-in user (id: 8,9 in this case)
(2) Turn each record with the each method. (This time it will be turned twice)
③ Since there is one or more order_id for each time in each method, turn it again with each method (this time, order_id: 8 is 3 times, order_id: 9 is 1 time).
I'm thinking of implementing it in the flow, but it didn't work.

↓ Current bad example

(users_controller.rb)
def show
    @user = User.find (params [: id])
    @orders = Order.where (user_id: current_user)
 end
