Django频道：将邮件保存到数据库

问题描述

我是频道的新手，并且按照他们的官方文档提出了聊天室申请。现在，我正在尝试保存聊天消息。我所知道的是我可以创建一个模型，但是Idk如何将其从consumers.py保存到我的数据库中。我在消息中添加了用户名。会有所帮助。

我的Consumers.py：

import json
from channels.generic.websocket import AsyncWebsocketConsumer

class ChatConsumer(AsyncWebsocketConsumer):
    async def connect(self):
        self.room_name = self.scope['url_route']['kwargs']['room_name']
        self.room_group_name = 'chat_%s' % self.room_name

        # Join room group
        await self.channel_layer.group_add(
            self.room_group_name,self.channel_name
        )

        await self.accept()

    async def disconnect(self,close_code):
        # Leave room group
        await self.channel_layer.group_discard(
            self.room_group_name,self.channel_name
        )

    # Receive message from WebSocket
    async def receive(self,text_data):
        username = self.scope["user"].first_name
        name = self.scope['user'].username
        text_data_json = json.loads(text_data)
        message = text_data_json['message']
        message = (username + '(' + name + ')' + ':\n' + message)

        # Send message to room group
        await self.channel_layer.group_send(
            self.room_group_name,{   
                'type': 'chat_message','message': message
            }
        )

    # Receive message from room group
    async def chat_message(self,event):
        username = self.scope["user"].username
        message = event['message']
        name = self.scope["user"].username

        # Send message to WebSocket
        await self.send(text_data=json.dumps({
            'message': message,"username": username,"name": name
        }))

我要保存消息的模型：

class Message(models.Model):
    author = models.ForeignKey(User,related_name='messages',on_delete=models.CASCADE)
    context = models.TextField()
    timestamp = models.DateTimeField(auto_Now_add=True)

解决方法

仅定期创建消息有什么问题？

message = Message.objects.create(context=message,author=self.scope['user'])
