AttributeError位於/ notify/notify /'UserNotifications'對象沒有屬性'user'

我試圖製作通知應用程序。我有一個收集關於用戶應該被通知的動作的信息的中間部分，並且在處理動作的視圖中，它會自動在UserNotification模型中創建一個實例。這一切都工作。現在，如果用戶的帖子被其他用戶所喜歡，那麼這些操作需要顯示在通知頁面上。但是，我顯然不希望任何人使用它來查看網站上正在創建的每個通知，而只是看到他們發佈的通知。AttributeError位於/ notify/notify /'UserNotifications'對象沒有屬性'user'

我遇到了視圖和基於當前用戶篩選通知的問題。更具體地講，我收到此錯誤：

AttributeError at /notify/notify/ 
'UserNotifications' object has no attribute 'user'

隨着回溯：

Traceback (most recent call last):

    response = get_response(request)

    File "/Users/garrettlove/Desktop/evverest/notify/views.py", line 30, in get_queryset 
    return UserNotification.objects.filter(user=request.user)

這是我的看法有關本：

// Bunch of imports are all here 

User = get_user_model() 

class UserNotifications(LoginRequiredMixin,ListView): 
    login_url = 'account_login' 
    model = UserNotification 
    template_name = 'notify/usernotification_list.html' 
    context_object_name = 'notifies' 
    paginate_by = 25 

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

這裏是我的UserNotification型號：

from django.db import models 
from django.contrib.auth import get_user_model 
from django.db.models.signals import post_save 
from django.dispatch import receiver 

User = get_user_model() 

# Create your models here. 
class UserNotification(models.Model): 
    user = models.ForeignKey(User,related_name='user',null=True) 
    post = models.ForeignKey('feed.UserPost',related_name='post') 
    timestamp = models.DateTimeField(auto_now_add=True) 
    notify_type = models.CharField(max_length=6) 
    read = models.BooleanField(default=False) 

    def __str__(self): 
     return str(self.user)
