python - 名称 'member_one' 在 django 中未定义错误

Question

我想从数据库中获取所有 Message_thread_private 实例，但出现错误 NameError: name 'member_one' is not defined

模型.py：

class Message_thread_private(models.Model):
    member_one = models.ForeignKey(User, related_name='member_one_messages', on_delete=models.CASCADE)
    member_two = models.ForeignKey(User, related_name='member_two_messages', on_delete=models.CASCADE)
    content = models.TextField()
    created = models.DateTimeField(auto_now_add=True)
    def __str__(self):
        return self.member_one.username

    def last_10_messages():
        return Message.objects.order_by('-timestamp').all()[:10]

视图.py：

@login_required
def room(request, room_name):
    users = User.objects.filter(is_active=True).exclude(username=request.user.username)
    messages = Message_thread_private.objects.filter(member_one.username==request.user.username)
    return render(request, 'chat/room.html', {
        'room_name_json': mark_safe(json.dumps(room_name)),
        'username': mark_safe(json.dumps(request.user.username)),
        'users': users,
    })

为什么我会收到此错误，我该如何解决？

您的代码中有两个错误。以下是更新后的代码。使用“=”代替“==”和“__”代替“。”

    @login_required
    def room(request, room_name):
        users = User.objects.filter(is_active=True).exclude(username=request.user.username)
        messages = Message_thread_private.objects.filter(member_one__username=request.user.username)
        return render(request, 'chat/room.html', {
            'room_name_json': mark_safe(json.dumps(room_name)),
            'username': mark_safe(json.dumps(request.user.username)),
            'users': users,
        })
