我有一個QuerySet，我需要將它發(fā)送到我的模板，因為我需要操縱它的值來生成一個JS數(shù)組。但在我看來，我使用： order_items = json.dumps(order_items)我明白了：Object of type QuerySet is not JSON serializable視圖：import jsondef thanks_deposit_payment(request):    order_number = Order.objects.latest('id').id    total = Order.objects.latest('id').total    costo_despacho = Order.objects.latest('id').shipping_cost    order_items = OrderItem.objects.filter(order=Order.objects.latest('id'))    # order_items = json.dumps(order_items)    response = render(request, 'thanks_deposit_payment.html', dict(order_number=order_number, total=total,                                                                   order_items=order_items, costo_despacho=costo_despacho))    return responsemodels.py：class OrderItem(models.Model):    order = models.ForeignKey(Order, on_delete=models.CASCADE)    product = models.CharField(max_length= 200)    quantity = models.CharField(max_length= 200)    size = models.CharField(max_length=200)    price = models.DecimalField(max_digits=10, decimal_places=2, verbose_name= 'PEN Price')    file = models.FileField(upload_to='files', blank=True, null=True)    comment = models.CharField(max_length=200, blank=True, null=True, default='')    uploaded_at = models.DateTimeField(auto_now_add=True)    class Meta:        db_table = "OrderItem"我需要使用從后端發(fā)送的order_items中的項來生成products數(shù)組： <script>        window.dataLayer = window.dataLayer || [];        window.dataLayer.push({            event: 'eec.purchase',            ecommerce: {                currencyCode: 'PEN',                purchase: {                    actionField: {                        id: {{ order_number }},                        affiliation: 'Stickers Gallito E-Commerce',                        revenue: {{ total }},                        shipping: {{ costo_despacho }},                        coupon: 'SUMMER2019'                    }                },                products: [
