Django REST framework basis: view and routing

We conducted a package is easier to use on the basis of the original modelserializers

 #author


classAuthorModelSerializers (serializers.ModelSerializer):
    classMeta -:
        Model=models.Author
        Fields="__all__ is"


fromrest_frameworkImportas mixins
fromrest_frameworkImportgenerics


classAuthorView (mixins.ListModelMixin, mixins.CreateModelMixin, generics.GenericAPIView):
    #QuerySet Serializer these two methods must be defined as a value that otherwise fail to
    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)

Generic class-based view (third package reduces the amount of code)

# Author 
class AuthorModelSerializers (serializers.ModelSerializer):
     class Meta -: 
        Model = models.Author 
        Fields = " __all__ is " 


from rest_framework Import as mixins
 from rest_framework Import generics 


# encapsulated layer 3 
class AuthorView (generics.ListCreateAPIView):
     # QuerySet both Serializer the method must be defined as the value otherwise fail to 
    QuerySet = models.Author.objects.all () 
    serializer_class = AuthorModelSerializers 


# encapsulated layer 3
class AuthorDetaiView (generics.RetrieveUpdateDestroyAPIView):
     # QuerySet Serializer these two methods must be defined as a value that otherwise fail to 
    QuerySet = models.Author.objects.all () 
    serializer_class = AuthorModelSerializers 

use viewset 
viewsets.ModelViewSet 

principle:

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 the Serializer both of these methods must be defined as a value that otherwise fail to 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 these two methods must be defined as a value that otherwise fail to
 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)
