Django消息应用程序-将消息显示为对话

问题描述

我从Django开始，对Django-messages应用程序一目了然。我决定遵循他们的方式。感谢 parent_message 和 timestamp ，我们可以显示视图对话（发送者和接收者）。

在我的message_view.html中，我得到了最后一条消息（实际上是来自用户的消息），并且由于回复视图，我有可能回答该消息。

任何人都没有关于如何显示整个对话的想法。我进入了模板的前两个步骤：

• 最后一条消息（message.id，实际上是来自用户的消息）
• 回答形式（）
• 所有对话（message.id的parent_messages和时间戳）

message / models.py

class Message(models.Model):
     sender = models.ForeignKey(User,on_delete=models.CASCADE,related_name='sender')        
     receiver = models.ForeignKey(User,related_name='receiver')        
     message = models.CharField(max_length=1000)
     parent_message = models.ForeignKey('self',related_name='next_messages',null=True,blank=True,on_delete=models.SET_NULL)
     timestamp = models.DateTimeField(auto_Now_add=True)
     read_at = models.DateTimeField(_("read at"),blank=True)
     replied_at = models.DateTimeField(_("replied at"),blank=True)     
     #is_read = models.BooleanField(default=False)
     
     def new(self):
         if self.read_at is not None:
             return False
         return True

     def replied(self):
         if self.replied_at is not None:
             return True
         return False
     
     def __str__(self):
           return self.message
     class Meta:
           ordering = ('timestamp',)
           
     def inBox_count_for(user):
         return Message.objects.filter(receiver=user,read_at__isnull=True).count()

            return HttpResponseRedirect(success_url)
    else:
        form = form_class(initial={
            'message': quote_helper(parent.sender,parent.message),'receiver': [parent.sender,]
            })
    return render(request,{
        'form': form,})
