Question

我正在尝试构建一个消息传递应用。这是我的模特，

class Message(models.Model):
    sender = models.ForeignKey(User, related_name="sender")
    receiver = models.ForeignKey(User, related_name="receiver")
    msg_content = models.TextField()
    created_at = models.DateTimeField(auto_now_add=True)

这是我在视野中尝试的，

data = Message.objects.filter(Q(sender=request.user) | Q(receiver=request.user))

在模板中，

{% for abc in data %}
    {{ abc.receiver }} <br/>
{% endfor %}

如我们在社交媒体平台上看到的那样，如何根据新消息获取不同用户并重新排序？

Answer 1

你可以试试这段代码

inbox_message = Message.objects.filter.objects.filter(receiver=request.user).order_by('-created_at')

outbox_message = Message.objects.filter.objects.filter(sender=request.user).order_by('-created_at')

Answer 2

这里你需要做的事情，

获取发件人request.user rec - somename
为上述发件人获取receivedMsg，接收者request.user serder - somename

message_queue = Message.objects.filter（Q（receiver = rec_name，sender = request.user），Q（receiver = request.user，sender = rec_name）.order_by（＆＃39; -created_at＆＃39;）< / p>

按创建者的顺序将像链一样随机播放
