# 写序列化类

首先自己得写好model

from django.db import models

# Create your models here.

class Person(models.Model):
    first_name = models.CharField(max_length=30)
    last_name = models.CharField(max_length=30)

在app中新建一个ser.py

from rest_framework.serializers import ModelSerializer
from demo1.models import Person

class PersonModelSerializer(ModelSerializer):

    class Meta:
        model = Person
        fields = "__all__"

from django.shortcuts import render
from .ser import PersonModelSerializer
from .models import Person
from rest_framework.viewsets import ModelViewSet

# Create your views here.

class PersonViewSet(ModelViewSet):
    queryset = Person.objects.all()
    serializer_class = PersonModelSerializer

# 写路由关系

from django.contrib import admin
from django.urls import path

from demo1 import views
from rest_framework.routers import DefaultRouter

router = DefaultRouter()  # 可以处理视图的路由器
router.register('persons', views.PersonViewSet)  # 向路由器中注册视图集

# 将路由器中的所有路由信息追到django的路由列表中

urlpatterns = [
    path('admin/', admin.site.urls),
]
urlpatterns += router.urls
