    <p>I have the following models in my Django app where An <strong>Order</strong> is related to a <strong>Cart</strong>, a <strong>cartItem</strong> is related to a <strong>Cart</strong> and a <strong>product</strong>. Now in my tastypie api when i GET an order i also want to get all the products associated with the order's cart.</p> <pre><code>class Order(models.Model): objects = OrderManager() order_number = models.CharField(max_length=20, editable=False,unique=True, default=get_unique_order_number) user = models.ForeignKey(User, blank=True, null=True) cart = models.ForeignKey(Cart, blank=True, null=True) ... class Cart(models.Model): user = models.ForeignKey(User) is_check_out = models.BooleanField(default=False) ... class CartItem(models.Model): objects = CartItemManager() cart = models.ForeignKey(Cart) product = models.ForeignKey(Product) ... class CartRelatedResource(ModelResource): class Meta: queryset = Cart.objects.all() allowed_methods = ['get'] excludes = ['is_check_out', 'session', 'creation_date', 'modification_date'] include_resource_uri = False authentication = SessionAuthentication() class OrderResource(ModelResource): cart = fields.ForeignKey(CartRelatedResource, 'cart',full=True) class Meta: queryset = Order.objects.all() resource_name = 'order' fields = ['cart_id','delivery_time','shipping_address_id','billing_address_id', 'tip','phone','delivery_instructions'] include_resource_uri = False allowed_methods = ['post','get'] authentication = SessionAuthentication() authorization = OrderAuthorization() </code></pre> <p>I don't think using ToManyField will work in this case. Will it? What is the best way to achieve what i want?</p>

    1. COMaybe in `CartRelatedResource` you could define a field like this: `orders = fields.ToManyField(OrderResource, 'cart__order_set', related_name='cart')` I'm not a tastypie guy so not sure if it's gonna work..

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
