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 = Addr
        fields = '__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 = AddrSerializer
    permission_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 =True
    obj.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 =False
            item.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'),
