### 案例-使用GenericAPIView改写RestAPI ###

# views.py from rest_framework.generics import GenericAPIView from rest_framework import status from booktest.serializers import BookInfoSerializer from booktest.models import BookInfo # /books/ class BookListView(GenericAPIView): """ 获取所有图书、增加图书 """ # 指定视图所使用的序列化器类 serializer_class = BookInfoSerializer # 指定视图所使用的查询集 queryset = BookInfo.objects.all() def get(self, request): """ 获取所有的图书数据 """ queryset = self.get_queryset() # 序列化所有图书数据 serializer = self.get_serializer(queryset, many=True) return Response(serializer.data) def post(self, request): """ 新增一个图书数据 """ # 反序列化-数据校验 serializer = self.get_serializer(data=request.data) serializer.is_valid(raise_exception=True) # 反序列化-数据保存(save内部会调用序列化器类的create方法) serializer.save() return Response(serializer.data, status=status.HTTP_201_CREATED) # /books/(?P<pk>\d+)/ class BookDetailView(GenericAPIView): """ 获取、修改、删除指定图书 """ # 指定视图所使用的序列化器类 serializer_class = BookInfoSerializer # 指定视图所使用的查询集 queryset = BookInfo.objects.all() def get(self, request, pk): """ 获取指定图书 """ instance = self.get_object() # 将图书数据进行序列化 serializer = BookInfoSerializer(instance) return Response(serializer.data) def put(self, request, pk): """ 修改指定图书 """ instance = self.get_object() # 反序列化-数据校验 serializer = BookInfoSerializer(instance, data=request.data) serializer.is_valid(raise_exception=True) # 反序列化-数据保存(save内部会调用序列化器类的update方法) serializer.save() return Response(serializer.data) def delete(self, request, pk): """ 删除指定图书： """ instance = self.get_object() instance.delete() return Response(status=status.HTTP_204_NO_CONTENT)
