Python Version: 2.7.10
Django Version: 1.9
REST framework 3.3.2
安装
pip install django
pip install djangorestframework
settings.py INSTALLED_APPS中引入rest_framework
INSTALLED_APPS = [ 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', 'app01', 'rest_framework', ]
创建model, 修改mdels.py
class Book(models.Model): name=models.CharField(max_length=100) title=models.CharField(max_length=100) author=models.CharField(max_length=100)
创建serializers.py
from app01.models import *
from rest_framework import serializers
class BookSerializer(serializers.Serializer):
name = serializers.CharField(max_length=100)
title = serializers.CharField(max_length=100)
author = serializers.CharField(max_length=100)
def create(self, validated_data):
return Book(**validated_data)
def update(self, instance, validated_data):
instance.email = validated_data.get('name', instance.name)
instance.content = validated_data.get('title', instance.title)
instance.created = validated_data.get('author', instance.author)
return instance
restore_object() 3.0以上版本不支持已经被create()和update()方法代替,源码如下：
( 'Serializer `%s.%s` has old-style version 2 `.restore_object()` ' 'that is no longer compatible with REST framework 3. ' 'Use the new-style `.create()` and `.update()` methods instead.' % (self.__class__.__module__, self.__class__.__name__) )
创建基于类和函数的视图
from django.shortcuts import render_to_response
from django.http import HttpResponse
from app01.forms import *
from rest_framework.views import APIView
from app01.serializers import BookSerializer
from app01.models import *
from rest_framework.response import Response
from rest_framework import generics
from rest_framework import status
# Create your views here.
class BookList(APIView):
def get(self,request,format=None):
books=Book.objects.all()
ser=BookSerializer(books, many=True)
return Response(ser.data)
def post(self,request,format=None):
ser=BookSerializer(data = request.data)
if ser.is_valid():
ser.create(ser.validated_data).save()
return Response(ser.data,status = status.HTTP_201_CREATED)
return Response(ser.errors)
class BookDetail(APIView):
def get(self,request,num,format=None):
b=Book.objects.get(id=num)
ser=BookSerializer(b)
return Response(ser.data)
class GenericBookList(generics.ListCreateAPIView):
queryset = Book.objects.all()
serializer_class = BookSerializer
def post(self,request,format=None):
ser=BookSerializer(data = request.data)
if ser.is_valid():
ser.create(ser.validated_data).save()
return Response(ser.data,status = status.HTTP_201_CREATED)
return Response(ser.errors)
def index(request):
return render_to_response('index.html')
def hello(request):
if request.method == 'POST':
form = BookForms(request.POST)
if form.is_valid():
data = form.cleaned_data
title = data["title"]
return HttpResponse(title)
form = BookForms()
return render_to_response('1.html', {'form':form})
urls.py配置
from django.conf.urls import url from django.contrib import admin from app01.views import * urlpatterns = [ url(r'^admin/', admin.site.urls), url(r'^$', index), url(r'^hello/$', hello), url(r'^book/$', BookList.as_view()), url(r'^genericbook/$', GenericBookList.as_view()), url(r'^book/(\d+)', BookDetail.as_view()), ]
APIView
generic通用视图
RESTful Request：GET/PUT/DELETE/POST/HEAD/OPTIONS
POST请求被定义为创建“从属资源”(拥有父资源的资源) (add)
