Django Channels'ProgramConsumer'对象没有属性'reply_channel'

Question

我将基于类的函数用于Django通道，当我尝试获取与websocket_connect连接的客户端的Reply_channel时，会收到此错误。

我对频道比较陌生

Consumer.py

import asyncio
import json
from django.contrib.auth import get_user_model
from channels.consumer import AsyncConsumer
from channels.db import database_sync_to_async

from .models import  Thread, ChatMessage

class ProgramConsumer(AsyncConsumer):
    async def websocket_connect(self, message):
        print("connected", message)

        #What does this do??? Is it accepting the connection that is sent from the client html page
        await self.send({
                "type": "websocket.accept"
        }) #Execute that code and wait


        await self.reply_channel.send({
                "text": json.dumps({
                    "action": "reply_channel",
                    "reply_channel": message.reply_channel.name,
                })
            }
        )

我正在尝试复制下面的代码，但是要使用基于类的函数。

@channel_session
def ws_connect(message):
    message.reply_channel.send({
        "text": json.dumps({
            "action": "reply_channel",
            "reply_channel": message.reply_channel.name,
        })
    })

下面是我的HTML页面上的JQuery

JQuery

$(function() {
    console.log(window.location)
    var loc = window.location

    //var formData = $("#form") //Grabs the form element above
    //var msgInput = $("#id_message")
    //var chatHolder = $("#chat-items")
    //var me = $("#myUsername").val()

    var wsStart = 'ws://'
    if (loc.protocol == 'https:'){
        wsStart = 'wss://'
    }

    // Define endpoint
    var endpoint = wsStart + loc.host + loc.pathname

    // methods that come in the socket

   console.log("Connecting to " + endpoint)
   // Use endpoint
   var socket = new WebSocket(endpoint)

   // RECIEVING
   socket.onmessage = function(message) {
       console.log("Got message: " + message.data);
       var data = JSON.parse(message.data);
       // if action is started, add new item to table
       if (data.action == "started") {
           var task_status = $("#task_status");
           var ele = $('<tr></tr>');
           ele.attr("id", data.program_id);
           var item_id = $("<td></td>").text(data.program_id);
           ele.append(item_id);
           var item_name = $("<td></td>").text(data.program_name);
           ele.append(item_name);
           var item_status = $("<td></td>");
           item_status.attr("id", "item-status-"+data.program_id);
           var span = $('<span class="label label-primary"></span>').text(data.program_status);
           item_status.append(span);
           ele.append(item_status);
           task_status.append(ele);
       }
       // if action is completed, just update the status
       else if (data.action == "completed"){
           var item = $('#item-status-' + data.program_id + ' span');
           item.attr("class", "label label-success");
           item.text(data.program_status);
       }
   };
   // SENDING
   // Takes form data and stringifys it inso JSON action and program_name
   $("#taskform").on("submit", function(event) {
       var message = {
           action: "start_sec3",
           program_name: $('#task_name').val()
       };
       socket.send(JSON.stringify(message));
       $("#task_name").val('').focus();
       return false;
   });
});
