Vue+Django REST framework 打造生鲜电商项目9-1~

9-1 drf文档的功能

开始我文档一直报错,是因为我viewset有写错了,报的错也是viewset里面的

现在好用了,木哈哈

9-2 动态设置serializers和permissions获取用户信息

mixins.RetrieveModelMixin是对应网址 XXX/id

用一个viewset增删改查
user/views.py

动态serializers,因为在一个viewset中涉及注册,修改,获取,注册当然不能要求登录等权限.所以要分开写serializers,create和获取detail不是一个.
创建是userserializers,获取是userDetailserializers
user/serializers.py

class UserDetailSerializer(serializers.ModelSerializer):
    """
    用户详情序列化类
    """
    class Meta:
        model = User
        fields = ("name", "gender", "birthday", "email", "mobile")

user/views.py

class UserViewset(CreateModelMixin, mixins.RetrieveModelMixin, viewsets.GenericViewSet):
    """
    用户
    """
    serializer_class = UserRegSerializer
    queryset = User.objects.all()
    authentication_classes = (JSONWebTokenAuthentication, authentication.SessionAuthentication )

    def get_serializer_class(self):
        if self.action == "retrieve":
            return UserDetailSerializer
        elif self.action == "create":
            return UserRegSerializer

        return UserDetailSerializer

    # permission_classes = (permissions.IsAuthenticated, )
    def get_permissions(self):
        if self.action == "retrieve":
            return [permissions.IsAuthenticated()]
        elif self.action == "create":
            return []

        return []

    def create(self, request, *args, **kwargs):
        serializer = self.get_serializer(data=request.data)
        serializer.is_valid(raise_exception=True)
        user = self.perform_create(serializer)

        re_dict = serializer.data
        payload = jwt_payload_handler(user)
        re_dict["token"] = jwt_encode_handler(payload)
        re_dict["name"] = user.name if user.name else user.username

        headers = self.get_success_headers(serializer.data)
        return Response(re_dict, status=status.HTTP_201_CREATED, headers=headers)

    def get_object(self):
        return self.request.user

    def perform_create(self, serializer):
        return serializer.save()

运行结果,请求users/2/

这样请求走的是UserDetailSerializer.py

9-4 修改用户信息

就是简单的在views里面加入继承的mixins.UpdateModelMixin
接受put请求

9-5 用户收藏功能

用户收藏的serializers里面只返回了id,需要进一步解析货物的其他字段
还是把UserFavViewset分解成两个动作,一个是list,请求所有收藏,需要详细的字段
一个是创建和取消create只需要id和user_id.这样要在UserFavViewset里面做一个判断,来判断分别使用具体的哪个serializers.
体现在代码上就是viewset加一个判断,serializers里面加一个detal

user_operation/views.py

class UserFavViewset(mixins.CreateModelMixin, mixins.ListModelMixin, mixins.RetrieveModelMixin,
                     mixins.DestroyModelMixin, viewsets.GenericViewSet):
    """
    list:
        获取用户收藏列表
    retrieve:
        判断某个商品是否已经收藏
    create:
        收藏商品
    """
    permission_classes = (IsAuthenticated, IsOwnerOrReadOnly)
    authentication_classes = (JSONWebTokenAuthentication, SessionAuthentication)
    lookup_field = "goods_id"

    def get_queryset(self):
        return UserFav.objects.filter(user=self.request.user)

    # def perform_create(self, serializer):
    #     instance = serializer.save()
    #     goods = instance.goods
    #     goods.fav_num += 1
    #     goods.save()

    def get_serializer_class(self):
        if self.action == "list":
            return UserFavDetailSerializer
        elif self.action == "create":
            return UserFavSerializer

        return UserFavSerializer

user_operation/serializers.py

class UserFavDetailSerializer(serializers.ModelSerializer):
    goods = GoodsSerializer()

    class Meta:
        model = UserFav
        fields = ("goods", "id")

运行效果:

9-6 用户留言功能

urls

#留言
router.register(r'messages', LeavingMessageViewset, base_name="messages")

留言功能没有新鲜事情
还是view-serializers-url这一套.

user_operation/views.py


class LeavingMessageViewset(mixins.ListModelMixin, mixins.DestroyModelMixin, mixins.CreateModelMixin,
                            viewsets.GenericViewSet):

    """

    permission_classes = (IsAuthenticated, IsOwnerOrReadOnly)
    authentication_classes = (JSONWebTokenAuthentication, SessionAuthentication)
    serializer_class = LeavingMessageSerializer

    def get_queryset(self):
        return UserLeavingMessage.objects.filter(user=self.request.user)

    """
    收货地址管理
