這篇文章給大家介紹如何正確的使用Restful_framework視圖組件，內容非常詳細，感興趣的小伙伴們可以參考借鑒，希望對大家能有所幫助。
一、基本視圖
寫一個出版社的增刪查改resful接口
要自己事先創建好django項目，并創建好表，添加完記錄
路由：
url(r'^publish/$', views.PublishView.as_view()),
url(r'^publish/(?P<pk>\d+)/$', views.PublishDetailView.as_view()),
視圖：
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)
# 序列化數據
return Response(bs.data) #返回的結果是列表中套字典
def post(self, request):
# 添加一條數據
print(request.data)
bs=PublishSerializers(data=request.data)
if bs.is_valid():
bs.save() # 生成記錄
return Response(bs.data) #返回的是添加成功記錄的字典
else:
return Response(bs.errors)
class PublishDetailView(APIView): #查詢某一條數據
def get(self,request,pk):
publish_obj=models.Publish.objects.filter(pk=pk).first()
bs=PublishSerializers(publish_obj,many=False)
return Response(bs.data) #更新某一條數據
def put(self,request,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) #刪除某一條數據
def delete(self,request,pk):
models.Publish.objects.filter(pk=pk).delete()
return Response("")二、mixins類和generic類編寫視圖
路由：
url(r'^publishes$', views.Publish.as_view()),
url(r'^publish/(?P<pk>\d+)', views.PublishDetail.as_view()),
視圖：
from api import models
from rest_framework import serializers
from rest_framework import mixins
from rest_framework.generics import GenericAPIView
class PublishSer(serializers.ModelSerializer):
class Meta:
model=models.Publish
fields='__all__'
class Publish(GenericAPIView,mixins.ListModelMixin,mixins.CreateModelMixin):
queryset = models.Publish.objects.all()
serializer_class = PublishSer
def get(self,request):
return self.list(request) #在ListModelMixin下有一個list方法，返回的就是查詢的結果:Response(serializer.data)
def post(self,request):
return self.create(request) #已經封裝好了，幫我們做校驗和序列化，返回的是添加成功的記錄
class PublishDetail(GenericAPIView,mixins.DestroyModelMixin,mixins.RetrieveModelMixin,mixins.UpdateModelMixin):
queryset = models.Publish.objects.all()
serializer_class = PublishSer
def get(self,request,*args, **kwargs):
return self.retrieve(request,*args, **kwargs)
def put(self,request,*args, **kwargs):
return self.update(request,*args, **kwargs)
def delete(self,request,*args, **kwargs):
return self.destroy(request,*args, **kwargs)三、使用generic下ListCreateAPIView和RetrieveUpdateDestroyAPIView
路由：
url(r'^publishes$', views.Publish.as_view()),
url(r'^publish/(?P<pk>\d+)', views.PublishDetail.as_view()),
視圖：
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'})),
url(r'^publish/(?P<pk>\d+)', views.Publish.as_view({'get': 'retrieve', 'put': 'update', 'delete': 'destroy'})),
視圖：
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關于如何正確的使用Restful_framework視圖組件就分享到這里了，希望以上內容可以對大家有一定的幫助，可以學到更多知識。如果覺得文章不錯，可以把它分享出去讓更多的人看到。
