一、基本檢視

寫一個出版社的增刪查改resful介面

要自己事先建立好django專案，並建立好表，新增完記錄

路由：

url(r'^publish/$',views.PublishView.as_view()),
url(r'^publish/(?P<pk>\d+)/$',views.PublishDetailView.as_view()),

檢視：

from api import modelsfrom rest_framework import serializersfrom rest_framework.response import Responsefrom rest_framework.views import APIView
class PublishSerializers(serializers.ModelSerializer):
  class Meta:
    model=models.Publish
    fields='__all__'

class PublishView(APIView):
　　#查詢出版社表中所有記錄
  def get(self,request):
    publish_list = models.Publish.objects.all()
    bs = PublishSerializers(publish_list,many=True)
    # 序列化資料

    return Response(bs.data)  #返回的結果是列表中套字典
　　
  def post(self,request):
    # 新增一條資料
    print(request.data)

    bs=PublishSerializers(data=request.data)
    if bs.is_valid():
      bs.save() # 生成記錄
      return Response(bs.data)  #返回的是新增成功記錄的字典
    else:

      return Response(bs.errors)

class PublishDetailView(APIView):　　 #查詢某一條資料
  def get(self,request,pk):
    publish_obj=models.Publish.objects.filter(pk=pk).first()
    bs=PublishSerializers(publish_obj,many=False)
    return Response(bs.data)　　 #更新某一條資料
  def put(self,pk):
    publish_obj = models.Publish.objects.filter(pk=pk).first()

    bs=PublishSerializers(data=request.data,instance=publish_obj)
    if bs.is_valid():
      bs.save() # update
      return Response(bs.data)
    else:
      return Response(bs.errors)　　 #刪除某一條資料
  def delete(self,pk):
    models.Publish.objects.filter(pk=pk).delete()

    return Response("")

二、mixins類和generic類編寫檢視

路由：

url(r'^publishes$',views.Publish.as_view()),
url(r'^publish/(?P<pk>\d+)',views.PublishDetail.as_view()),

檢視：

from api import models
from rest_framework import serializers
from rest_framework import mixins
from rest_framework.generics import GenericAPIView
class PublishSer(serializers.ModelSerializer):
  class Meta:
    model=models.Publish
    fields='__all__'
class Publish(GenericAPIView,mixins.ListModelMixin,mixins.CreateModelMixin):
  queryset = models.Publish.objects.all()
  serializer_class = PublishSer
  def get(self,request):
    return self.list(request)  #在ListModelMixin下有一個list方法，返回的就是查詢的結果:Response(serializer.data)
  def post(self,request):
    return self.create(request) #已經封裝好了，幫我們做校驗和序列化，返回的是新增成功的記錄
class PublishDetail(GenericAPIView,mixins.DestroyModelMixin,mixins.RetrieveModelMixin,mixins.UpdateModelMixin):

  queryset = models.Publish.objects.all()
  serializer_class = PublishSer
  def get(self,*args,**kwargs):
    return self.retrieve(request,**kwargs)

  def put(self,**kwargs):
    return self.update(request,**kwargs)

  def delete(self,**kwargs):
    return self.destroy(request,**kwargs)

三、使用generic下ListCreateAPIView和RetrieveUpdateDestroyAPIView

路由：

url(r'^publishes$',

檢視：

from api import models
from rest_framework import mixins
from rest_framework.generics import GenericAPIView
from rest_framework.generics import ListCreateAPIView,RetrieveUpdateDestroyAPIView
from rest_framework import serializers
class Publishser(serializers.ModelSerializer):
  class Meta:
    model=models.Publish
    fields='__all__'

class Publish(ListCreateAPIView):
  queryset = models.Publish.objects.all()
  serializer_class = Publishser

class PublishDetail(RetrieveUpdateDestroyAPIView):
  queryset = models.Publish.objects.all()
  serializer_class = Publishser

四、使用ModelViewSet

路由：

url(r'^publish$',views.Publish.as_view({'get':'list','post':'create'})),views.Publish.as_view({'get': 'retrieve','put': 'update','delete': 'destroy'})),

檢視：

from rest_framework.viewsets import ModelViewSet
from api import models
from rest_framework import serializers
class Publishser(serializers.ModelSerializer):
  class Meta:
    model=models.Publish
    fields='__all__'
class Publish(ModelViewSet):
  queryset = models.Publish.objects.all()
  serializer_class = Publishser
