model模块

from django.db import models

class usermodel(models.model):
    username = models.charfield(max_length=32)
    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)
