3通过课程查询商品信息

只需要修改/course/course/1/返回的数 据即可

1.1 course/serializers.py 添加商品信息序列化

from goods.serializers import GoodsSerializer
class CourseDeepSerializer(CourseSer):
    goods_set = GoodsSerializer(many=True)
    chapters = ChaptersSer(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
