AttributeError：“帐户”对象没有属性“排除”

Question

我建立了通知系统，我想在给自己的帖子添加赞时排除帖子的作者，所以收到通知，我遇到了这个问题

我的看法

def add_remove_like(request, pk):
data = {}
video = Video.objects.get(pk=pk)

if request.method == "POST":
    user = request.user
    if video.likes.filter(id=user.id).exists():
        liked = False
        video.likes.remove(user)
    else:
        video.likes.add(user)

        instance = video.author
        content_type = ContentType.objects.get_for_model(instance)

        try:
            notify = Notify.objects.create(from_user=request.user.exclude(from_user=instance), target=instance, content_type=content_type,
                                           redirect_url=f"{settings.BASE_URL}/video/account/video/{video.pk}",
                                           object_id=instance.pk,
                                           verb=f"{request.user} added like to your video"
                                           )
            notify.timestamp = timezone.now()
            notify.save()

request.user 是一个对象，而不是查询集。所以exclude 在这里不起作用。所以你可以像这样更新代码：

from_user = request.user if request.user != instance else None
notify = Notify.objects.create(
    from_user= from_user,
    target=instance,
    content_type=content_type,
    redirect_url=f"{settings.BASE_URL}/video/account/video/{video.pk}",
    object_id=instance.pk,
    verb=f"{request.user} added like to your video",
    timestamp=timezone.now()
)

我已经删除了像 notify.save() 这样的其他代码，因为如果您在查询集的 create 方法中添加时间戳，它是重复的。
