Django REST framework基础：视图和路由

在原来modelserializers基础上进行了一次封装方便了使用# author


class AuthorModelSerializers(serializers.ModelSerializer):
    class Meta:
        model = models.Author
        fields = "__all__"


from rest_framework import mixins
from rest_framework import generics


class AuthorView(mixins.ListModelMixin, mixins.CreateModelMixin, generics.GenericAPIView):
    # queryset serializer 这两个方法一定要定义成这个不然取不到值
    queryset = models.Author.objects.all()
    serializer_class = AuthorModelSerializers

    def get(self, request, *args, **kwargs):
        return self.list(request, *args, **kwargs)

    def post(self, request, *args, **kwargs):
        return self.create(request, *args, **kwargs)


class AuthorDetaiView(mixins.RetrieveModelMixin, mixins.DestroyModelMixin, mixins.UpdateModelMixin,
                      generics.GenericAPIView):
    # queryset serializer 这两个方法一定要定义成这个不然取不到值
    queryset = models.Author.objects.all()
    serializer_class = AuthorModelSerializers

    def get(self, request, *args, **kwargs):
        return self.retrieve(request, *args, **kwargs)

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

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

使用通用的基于类的视图（封装第三次减少了代码量）

# author
class AuthorModelSerializers(serializers.ModelSerializer):
    class Meta:
        model = models.Author
        fields = "__all__"


from rest_framework import mixins
from rest_framework import generics


# 封装了3层
class AuthorView(generics.ListCreateAPIView):
    # queryset serializer 这两个方法一定要定义成这个不然取不到值
    queryset = models.Author.objects.all()
    serializer_class = AuthorModelSerializers


# 封装了3层
class AuthorDetaiView(generics.RetrieveUpdateDestroyAPIView):
    # queryset serializer 这两个方法一定要定义成这个不然取不到值
    queryset = models.Author.objects.all()
    serializer_class = AuthorModelSerializers使用视图集viewsets.ModelViewSet原理：
