一.准备环境
1>.创建一个apps
python manage.py startapp idcs
2>. 创建一个apps的包，以后将创建的项目都移动至改目录中并配置相应的环境目录。这样做的目录是便于管理，否则随着项目的增多，咱们的根目录的文件夹也越多
import sys sys.path.insert(0,os.path.join(BASE_DIR,"apps")) #我们需要使用sys模块将BASE_DIR下的“apps”加入环境变了的第一个位置！
3>.检查idcs.apps.IdcsConfig中的name的值是否正确，如下图所示：
4>.安装与配置Django rest framework框架
bogon:~ yinzhengjie$ pip3.6 install djangorestframework Collecting djangorestframework Downloading https://files.pythonhosted.org/packages/ef/13/0f394111124e0242bf3052c5578974e88e62e3715f0daf76b7c987fc6705/djangorestframework-3.9.1-py2.py3-none-any.whl (950kB) 100% |████████████████████████████████| 952kB 18kB/s Installing collected packages: djangorestframework Successfully installed djangorestframework-3.9.1 You are using pip version 19.0.2, however version 19.0.3 is available.

5>.修改idcs.models.py配置文件
from django.db import models # Create your models here. class Idc(models.Model): name = models.CharField("机房名称",max_length=32) address = models.CharField("机房地址",max_length=256) phone = models.CharField("联系人",max_length=15) email = models.EmailField("邮件地址",default="null") letter = models.CharField("IDC简称",max_length=5) def __str__(self): return self.name class Meta: db_table = "resources_idc"
6>.查看数据库的表结构

二.序列化模型
1>.在idcs的apps中创建序列化文件，并编写序列化代码，如下图所示

五.总结
1>.序列化
1.1>.拿到queryset
1.2>.将queryset给序列化类
serializer = IdcSerializer(idc) #序列化一条数据 serializer = IdcSerializer(idc,many=True) #序列化多条数据
1.3>.转JSON格式
JSONRenderer().render(serializer.data)
2>.反序列化
from rest_framework.parses import JSONParser data = JSONParser().parse(BytesIO(content)) serializer = IdcSerializer(data=data) serializer.is_valid() serializer.save()
