In this video, we finish up our order details page by displaying each of the ordered product variations and their details. We start by iterating through all the product variations in the current order and show info like the product image, formatted price, product title, quantity, and the specifics of the variant (like size and color) using the variation's ancestors.
To make sure everything looks right, we place a new order with multiple products so we have more data to work with. Then, we update the UI so you can actually see all those details for every single variation in the order.
Along the way, we also pay attention to performance. We check the database query count and see there are way too many duplicate queries happening. To fix this, we add eager loading to our controller so all the required related data—like the product, media, and variant ancestors—gets pulled in efficiently, cutting way down on those database hits. After a bit of tweaking to include every relation we need, we confirm that the n+1 query problem is gone, and our orders page loads all its data much more efficiently.
By the end, we've got a complete, performant order details page displaying all the info we want. Next up, we'll take care of the order status sections!
