model模块

from django.db import models

class UserModel(models.Model):

    age = models.IntegerField()

    class Meta:
        db_table = 'user'

serializers模块

# 创建序列化类
from rest_framework import serializers
from App.models import UserModel

class UserSerializer(serializers.ModelSerializer):
    class Meta:
        model = UserModel
        fields = ('username', 'age')

views模块

from django.http import HttpResponse, JsonResponse

from django.views import View
from App.models import UserModel
from App.serializers import UserSerializer

class UserResource(View):
    def get(self, request):
        user = UserModel.objects.first()
        serializer = UserSerializer(user)
        return JsonResponse(serializer.data)

    def post(self, request):
        users = UserModel.objects.all()
        '对多个对象进行序列化时注意many'
        serializers = UserSerializer(users, many=True)
        '忽略安全性'
        return JsonResponse(serializers.data, safe=False)
