01收货地址模型类和视图定义_哔哩哔哩_bilibili 本博客借鉴至大佬的视频学习笔记

地址信息的管理：增删改查的实现

# 序列化器配置
class AddrSerializer(serializers.ModelSerializer):"""收货地址的模型序列化器"""class Meta:model = Addrfields = '__all__'# view 视图信息
class AddrView(GenericViewSet,mixins.ListModelMixin,mixins.CreateModelMixin,mixins.DestroyModelMixin,mixins.UpdateModelMixin):"""收货地址管理视图"""queryset =  Addr.objects.all()serializer_class = AddrSerializerpermission_classes = [IsAuthenticated,AddrPermissions]# filterset_fields = ('user',)def list(self, request, *args, **kwargs):queryset = self.filter_queryset(self.get_queryset())# 通过请求过来的用户进行过滤queryset = queryset.filter(user=request.user)page = self.paginate_queryset(queryset)if page is not None:serializer = self.get_serializer(page, many=True)return self.get_paginated_response(serializer.data)serializer = self.get_serializer(queryset, many=True)return Response(serializer.data)# url 配置
# 添加地址和获取地址列表的路由
path('address/', AddrView.as_view({'post':'create','get':'list'}), name='address'),
# 删除和修改地址
path('address/<int:pk>/', AddrView.as_view({'delete':'destroy','put':'update'}), name='address'),# 注册过滤器
'django_filters'# 配置过滤器
REST_FRAMEWORK = {# 过滤器信息配置'DEFAULT_FILTER_BACKENDS':['django_filters.rest_framework.DjangoFilterBackend',]
}

默认收货地址的设置

#  如上 AddrView视图中增加默认地址函数
def set_default_addr(self,request,*args,**kwargs):"""设置默认收货地址"""# 将获取的地址设置为默认obj =self.get_object()obj.is_default =Trueobj.save()# 将其他地址进行遍历为非默认queryset = self.get_queryset().filter(user=request.user)for item in queryset:if item !=obj:item.is_default =Falseitem.save()return Response({'message':'设置成功'},status=status.HTTP_200_OK)# url 文件配置
path('address/<int:pk>/default/', AddrView.as_view({'put': 'set_default_addr'}), name='address'),
