一、基本视图
写一个出版社的增删查改resful接口
要自己事先创建好django项目,并创建好表,添加完记录
路由:
url(r'^publish/$', views.PublishView.as_view()),
url(r'^publish/("htmlcode">from api import modelsfrom rest_framework import serializersfrom rest_framework.response import Responsefrom rest_framework.views import APIView class PublishSerializers(serializers.ModelSerializer): class Meta: model=models.Publish fields='__all__' class PublishView(APIView): #查询出版社表中所有记录 def get(self, request): publish_list = models.Publish.objects.all() bs = PublishSerializers(publish_list, many=True) # 序列化数据 return Response(bs.data) #返回的结果是列表中套字典 def post(self, request): # 添加一条数据 print(request.data) bs=PublishSerializers(data=request.data) if bs.is_valid(): bs.save() # 生成记录 return Response(bs.data) #返回的是添加成功记录的字典 else: return Response(bs.errors) class PublishDetailView(APIView): #查询某一条数据 def get(self,request,pk): publish_obj=models.Publish.objects.filter(pk=pk).first() bs=PublishSerializers(publish_obj,many=False) return Response(bs.data) #更新某一条数据 def put(self,request,pk): publish_obj = models.Publish.objects.filter(pk=pk).first() bs=PublishSerializers(data=request.data,instance=publish_obj) if bs.is_valid(): bs.save() # update return Response(bs.data) else: return Response(bs.errors) #删除某一条数据 def delete(self,request,pk): models.Publish.objects.filter(pk=pk).delete() return Response("")二、mixins类和generic类编写视图
路由:
url(r'^publishes$', views.Publish.as_view()),
url(r'^publish/("htmlcode">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下有一个list方法,返回的就是查询的结果:Response(serializer.data) def post(self,request): return self.create(request) #已经封装好了,帮我们做校验和序列化,返回的是添加成功的记录 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$', views.Publish.as_view()),
url(r'^publish/("htmlcode">from api import models from rest_framework import mixins from rest_framework.generics import GenericAPIView from rest_framework.generics import ListCreateAPIView,RetrieveUpdateDestroyAPIView from rest_framework import serializers class Publishser(serializers.ModelSerializer): class Meta: model=models.Publish fields='__all__' class Publish(ListCreateAPIView): queryset = models.Publish.objects.all() serializer_class = Publishser class PublishDetail(RetrieveUpdateDestroyAPIView): queryset = models.Publish.objects.all() serializer_class = Publishser四、使用ModelViewSet
路由:
url(r'^publish$',views.Publish.as_view({'get':'list','post':'create'})),
url(r'^publish/("htmlcode">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以上就是本文的全部内容,希望对大家的学习有所帮助,也希望大家多多支持。
