返回值类型是否必须说明order_idint是订单iduserstr是用户名total_countint是商品总量total_amountint是总价freightint是运费pay_methodint是支付方式statusint是订单状态create_timedate是订单日期skus数组是订单商品信息 后端实现

class OrdersView(ModelViewSet):
    serializer_class = OrderSeriazlier
    queryset = OrderInfo.objects.all()
    pagination_class = PageNum

序列化器的定义，在返回数据时涉及到三张表的嵌套返回，订单基本信息表，订单商品表，商品sku表

from rest_framework import serializers
from orders.models import OrderInfo, OrderGoods
from goods.models import SKU
from .skus import SKUGoodsSerializer


class SKUSerializer(serializers.ModelSerializer):
    """
        商品sku表序列化器
    """

    class Meta:
        model = SKU
        fields = ('name', 'default_image')


class OrderGoodsSerializers(serializers.ModelSerializer):
    """
        订单商品序列化器
    """
    # 嵌套返回sku表数据
    sku = SKUGoodsSerializer(read_only=True)

    class Meta:
        model = OrderGoods
        fields = ('count', 'price', 'sku')


class OrderSeriazlier(serializers.ModelSerializer):
    """
        订单序列化器
    """
    # 关联嵌套返回 用户表数据和订单商品表数据
    user = serializers.StringRelatedField(read_only=True)
    skus = OrderGoodsSerializers(many=True, read_only=True)

    class Meta:
        model = OrderInfo
        fields = '__all__'
