有深度depth的serializers.py

serializers.py

class CartInfoSerializer(serializers.ModelSerializer):
    class Meta:
        model = CartInfos
        fields = '__all__'

        # depth 根据外键关联实现序列化嵌套功能
        depth = 1

 

=》当然，需要restframework的支持

得到的结果为

    "state": "success",
    "msg": "获取成功",
    "data": [
        {
            "id": 1,
