动态设置serializer和permission获取用户信息

获取详情只需要添加一个mixins.RetrieveModelMixin,就行了

用户详情的序列化
users/serializers.py

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

views.py

class UserViewset(mixins.CreateModelMixin, mixins.RetrieveModelMixin, mixins.UpdateModelMixin, viewsets.GenericViewSet):
    '''
    用户信息管理
    create:
        用户注册
    retrieve:
        个人信息
    update:
        修改个人信息
    '''
    queryset = User.objects.all()
    authentication_classes = (JSONWebTokenAuthentication, authentication.SessionAuthentication)

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

        # 注册成功直接生成token,自动登陆
        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)

        # 返回的不是serializer.data,而是我们自己写的re_dict
        return Response(re_dict, status=status.HTTP_201_CREATED, headers=headers)

    # 这里需要动态权限配置
    # 1.用户注册的时候不应该有权限限制
    # 2.当想获取用户详情信息的时候，必须登录才行
    def get_permissions(self):
        if self.action == "retrieve":
            return [permissions.IsAuthenticated(), ]
        elif self.action == "create":
            return []

        return []

    # 这里需要动态选择用哪个序列化方式
    # 1.UserRegSerializer（用户注册），只返回username和mobile，会员中心页面需要显示更多字段，所以要创建一个UserDetailSerializer
    # 2.问题又来了，如果注册的使用userdetailSerializer，又会导致验证失败，所以需要动态的使用serializer
    def get_serializer_class(self):
        if self.action == "retrieve":
            return UserDetailSerializer
        elif self.action == "create":
            return UserRegSerializer

        return UserDetailSerializer

    # 虽然继承了Retrieve可以获取用户详情，但是并不知道用户的id，所有要重写get_object方法
    # 重写get_object方法，就知道是哪个用户了
    def get_object(self):
        return self.request.user

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

用户个人信息修改,只需要继承mixins.UpdateModelMixin就可以了

用户收藏

user_operation/serializer.py

class UserFavDetailSerializer(serializers.ModelSerializer):
    '''
    用户收藏详情
    '''

    # 通过商品id获取收藏的商品，需要嵌套商品的序列化
    goods = GoodsSerializer()

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

views.py

class UserFavViewset(viewsets.GenericViewSet, mixins.ListModelMixin, mixins.CreateModelMixin, mixins.DestroyModelMixin):
    '''
    list:
        获取用户的所有收藏
    create:
        添加收藏
    destroy:
        取消收藏
    '''
    # permission是用来做权限判断的
    # IsAuthenticated：必须登录用户；IsOwnerOrReadOnly：必须是当前登录的用户
    permission_classes = (IsAuthenticated, IsOwnerOrReadOnly)
    # auth使用来做用户认证的
    authentication_classes = (JSONWebTokenAuthentication, SessionAuthentication)
    # 搜索的字段
    lookup_field = 'goods_id'

    def get_queryset(self):
        # 只能查看当前登录用户的收藏，不会获取所有用户的收藏
        return UserFav.objects.filter(user=self.request.user)

    # 动态选择serializer
    def get_serializer_class(self):
        if self.action == "list":
            return UserFavDetailSerializer
        elif self.action == "create":
            return UserFavSerializer
        return UserFavSerializer

用户留言功能

user_operation/serializers.py

class LeavingMessageSerializer(serializers.ModelSerializer):
    '''
    用户留言
    '''
    # 获取当前登录的用户
    user = serializers.HiddenField(
        default=serializers.CurrentUserDefault()
    )
    # read_only:只返回，post时候可以不用提交，format：格式化输出
    add_time = serializers.DateTimeField(read_only=True, format='%Y-%m-%d %H:%M')

    class Meta:
        model = UserLeavingMessage
        fields = ("user", "message_type", "subject", "message", "file", "id", "add_time")

views.py

class LeavingMessageViewset(mixins.ListModelMixin, mixins.DestroyModelMixin, mixins.CreateModelMixin,
                            viewsets.GenericViewSet):
    """
    list:
        获取用户留言
    create:
        添加留言
    delete:
        删除留言功能
    """

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

    # 只能看到自己的留言
    def get_queryset(self):
        return UserLeavingMessage.objects.filter(user=self.request.user)

urls.py

# 配置用户留言的url
router.register(r'messages', LeavingMessageViewset, base_name="messages")

用户收获地址

user_operation/serializers.py

class AddressSerializer(serializers.ModelSerializer):
    user = serializers.HiddenField(
        default=serializers.CurrentUserDefault()
    )
    add_time = serializers.DateTimeField(read_only=True, format='%Y-%m-%d %H:%M')

    class Meta:
        model = UserAddress
        fields = ("id", "user", "province", "city", "district", "address", "signer_name", "add_time", "signer_mobile")

views.py

class AddressViewset(viewsets.ModelViewSet):
    """
    收货地址管理
    list:
        获取收货地址
    create:
        添加收货地址
    update:
        更新收货地址
    delete:
        删除收货地址
    """
    permission_classes = (IsAuthenticated, IsOwnerOrReadOnly)
    authentication_classes = (JSONWebTokenAuthentication, SessionAuthentication)
    serializer_class = AddressSerializer

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

urls.py

router.register(r'address',AddressViewset , base_name="address")
