I am trying to open a websocket connection from my angular 2+ app with my Django backend using Django Channels. I went through this tutorial: [this video] and managed to get everything working with the javascript portion written inline in a Django html template. But I am having issues simply opening a websocket connection when I migrated the front-end chat form to a separate angular 2 app. Both font-end and backends are hosted locally. Front End - Chat Form Template <div *ngFor="let message of thread.messages"> <div>{{message.message}}</div> </div> <form #formData [formGroup]="form"> <div class="form-group"> <input formControlName="messageInput" #msgInput type="text" class="form-control" id="newM

There's no way to do this with django out of the box. You can achieve this using django-channels and a client side app that connect to the websocket. If you need help with this, try to watch and follow this video: [this video]
Recommends some nooby questions · 2021-10 · Stack Overflow · on “self.scope['user'] always shows me the same user, Django Channels”
I am a beginner in Django Channels and I try to make a chat app. I think everything works fine, but the problem is that the message is not send to both of users connected to the room, just to the one of theme. I think the problem is inside consumer.py in user = self.scope['user'] becuase if I print the user it shows me every time only the first user that wrote something. So if I have two users: user1 and user2 and if user2 write something as first, it user = self.scope['user'] will always give me the second user. I am using Redis by WSL2. Based on this tutorial: [this video] an example console log if one of the user send something: receive {'type': 'websocket.receive', 'text': '{"message":"abc"}'

I am new to Django channels and I am following this tutorial on youtube [this video] All the setup is working great, but now I have been bowled by a conflict in the video and the shared git hub code. In the video if you exactly freez on 47:44 it will show you a screen where 2 browser windows are open with the following urls, 127.0.0.1:8000/messages/jmitchell3/ 127.0.0.1:8000/messages/cfe/ Here note that cfe is the user logged into the django admin. Now the model manager code says the following, class ThreadManager(models.Manager): def by_user(self, user): qlookup = Q(first=user) | Q(second=user) qlookup2 = Q(first=user) & Q(second=user) qs = self.get_queryset().filter(qlookup).exclude(qlookup2).d

I have React-Django application (I am using Django Rest Framework) and I am trying to integrate websockets with the channels & channels-redis package from django.
