通过课程查询商品信息

1.只需要修改/course/sourse/1/返回的在这里插入代码片数 据即可

1.1 course/serializers.py 添加商品信息序列化

# 添加显示商品字段 
from goods.serializers import GoodsSerializer 
class CourseDeepSerializer(CourseSerializer): 
    goods_set = GoodsSerializer(many=True) 
    chapters = ChaptersSerializer(many=True)

1.2 在 goods/serializers.py 中添加序列化函数

# -*- coding: utf-8 -*- 
from rest_framework import serializers 
from goods.models import Goods class 

GoodsSerializer(serializers.ModelSerializer): 
    class Meta: 
        model = Goods 
        fields = '__all__' # 所有字段

2.测试

{ 
    "id": 1, 
    "goods_set": [ 
        { 
            "id": 2,
