Hi everyone,

From Django Series: Part 2 - Designing and Implementing a Shopping Cart API - 5 - Getting a Cart,

when I paste UUID previously generated in page url, this message is returned:

# Page not found (404)

| Request Method: | GET |
| --- | --- |
| Request URL: | [http://127.0.0.1:8000/store/carts/7fd7585f-49f3-4009-83c6-49a97aba16f3](http://127.0.0.1:8000/store/carts/7fd7585f-49f3-4009-83c6-49a97aba16f3) |

I don’t understand why I can’t reach the cart instance.

Thank you for your help.

Mosh’s video cut off the beginning of the solution where he adds “RetrieveModelMixin” to the CartViewSet so it becomes:

```auto
class CartViewSet(CreateModelMixin, RetrieveModelMixin, GenericViewSet):
    queryset = Cart.objects.all()
    serializer_class = CartSerializer

```

You see that he added it at timestamp 8:36 of the lesson 5 video.

I found it from these smart people on the forum here and here:

> I implemented an api, which can create a cart with UUID. When I tried to get a cart using a url like [http://localhost:8001/store/carts/b4ff4b1b9fdc4c2d8ad09a8323c805dc/](http://localhost:8001/store/carts/b4ff4b1b9fdc4c2d8ad09a8323c805dc/), the browser returned 404 page not found. I’m sure this cart\_id:b4ff4b1b9fdc4c2d8ad09a8323c805dc is stored in the store\_cart table in the database. I checked the generated url patterns from django and I found out the cart url patterns were not included cart\_details pattern. Anyone knows what cause this issue?

> Edit I’ve solved my bug, I didn’t add (RetrieveModelMixin) to the cart view set expressionless so make sure you add this model to the cart view set , see 8:30 of the lesson 5 getting card Thank you so much @ariel.robaldo I appreciate your reply.
