通过课程信息查询商品信息

 

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)

2. 在goods/serializers.py中添加序列化函数

from rest_framework import serializers
from goods.models import Goods
​
class GoodsSerializer(serializers.ModelSerializer):
    class Meta:
        model = Goods
        fields = '__all__'

3. 测试
