APIView单一资源的查看更新删除

APIView单一资源的查看更新删除

一、构建路由

re_path("author/(/d+)",AuthorDetailView.as_view)),

二、视图类
在views.py中添加AuthorDetailView类

class AuthorDetailView(APIView):def get(self, request, pk):author = Author.objects.get(pk=pk)serializer = AuthorSerializer(instance=author,many=False)return Response(serializer.data)def put(self, request, pk):author = Author.objects.get(pk=pk)serializer = AuthorSerializer(instance=author, data=request.data)if serializer.is_valid():serializer.save()return Response(serializer.data)else:return Response(serializer.errors)def delete(self, request, pk):Author.objects.get(pk=pk).deletereturn Response()

三、修改序列化器类

在serializers.py中添加update方法

class AuthorSerializer(serializers.Serializer):name = serializers.CharField(max_length=32)age = serializers.IntegerField()def create(self,validated_data):author_obj = Author.objects.create(**validated_data)return author_objdef update(self, instance, validated_data):Author.objects.filter(pk=instance.pk).update(**validated_data)return instance

四、代码测试，用浏览器或者Postman
