Django Rest Framework 电商项目 9-6 用户留言功能

在views.py中：

from .models import UserFav, UserLeavingMessage

from .serializers import UserFavSerializer, UserFavDetailSerializer, LeavingMessageSerializer

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

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

在serializers.py中：

from .models import UserLeavingMessage

class LeavingMessageSerializer(serializers.ModelSerializer):
    user = serializers.HiddenField(
        default=serializers.CurrentUserDefault()
    )
    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")

配置url：

from user_operation.views import UserFavViewset, LeavingMessageViewset

router.register(r'messages', LeavingMessageViewSet, base_name="messages")

测试。发现file的完整url返回了，这样就有利于前端查看。

将vue中留言相关的host改为

local_host

为model中留言功能的file字段添加

upload_to="message/images/",
