justchat's Introduction

The Definitive Django Learning Platform.

Django Channels Tutorial Series

This tutorial is for how to build a chat application with Django Channels. The tutorial series can be watched here

To run the backend, run:

virtualenv env
source env/bin/activate
pip install -r requirements.txt
python manage.py runserver

To run the frontend:

npm i
npm start

To develop locally:

1. Change the `DEBUG` flag in `src/settings.js`
2. Create two users (easiest way might be to run `python manage.py createsuperuser` twice)
3. Using django admin, create a `Contact` object for each user.
4. Make sure you have an instance of redis running.

To build for deployment:

npm run build

Please note this is a demo project of the concepts used in building a chat app. It is simply not production ready. For example, when the backend receives a message, it'll broadcast to everyone in the room including the sender. This means when you demo the sender role, be aware you'll see every outbound message duplicated. The project is setup for deployment on Heroku however you'll need to follow tutorials on how to get this up and running

justchat's Issues

Duplicate Messages in React

Greetings;

I have just downloaded your project, which is great by the way, and i have noticed an issue;

When you send messages, the show up as duplicates in React Page, and they go away after refresh, is there a possible way to solve this issue ?

Request failed with status code 404

Whenever i try to create a chat it shows its shows 404 error`

Cannot import ASGI_APPLICATION module

raise ImproperlyConfigured("Cannot import ASGI_APPLICATION module %r" % path)
django.core.exceptions.ImproperlyConfigured: Cannot import ASGI_APPLICATION module 'justchat.routing'

Chat application between user and customersCppBuzz | Forum

Hi ,

I want to create a chat application with the help of Django-channels. Here I have two models users and customers.where user has credentials and customers don't have credentials...I want to establish a connection between users and customers

So can I create an application without logging in from the customer side?

django.db.utils.OperationalError: no such table: chat_contact

Hi. I made models.py by watching your video, but I'm not sure how to solve this problem.
First of all, when I access to 127.0.0.1:8000/admin/chat/chat/add,
It shows

django.db.utils.OperationalError: no such table: chat_contact

This is my models.py, and I migrated and deleted this models.py for several times.

from django.contrib.auth import get_user_model
from django.db import models

User = get_user_model()


# Create your models here.
class Contact(models.Model):
    user = models.ForeignKey(User, related_name='friends', on_delete=models.CASCADE)
    friends = models.ManyToManyField('self', blank=True)

    def __str__(self):
        return self.user.username


class Message(models.Model):
    contact = models.ForeignKey(Contact, related_name='messages', on_delete=models.CASCADE)
    content = models.TextField()
    timestamp = models.DateTimeField(auto_now_add=True)

    def __str__(self):
        return self.contact.user.username


class Chat(models.Model):
    participants = models.ManyToManyField(Contact, related_name='chats')
    messages = models.ManyToManyField(Message, blank=True)

    def last_10_messages(self):
        return self.messages.objects.order_by('-timestamp').all()[:10]

    def __str__(self):
        return "{}".format(self.pk)

And this is the Error Occurs.

Message port closing before response received

Hi,
I have written all the code and imported the .js, .html, and .css files from the repository. The only thing I havent done is change the WebSocket for a ReconectingWebSocket. I understood that it was an improvement, but since the WebSocket worked before adding all the "html styling", it should work after that as well. Granted I expected it might suffer from disconnects every now and then, but it simply doesn't start. Why is it that it works on the simple html version of rooms.html but once we stylize it, it stops working? I am tryin to understand the bottom of it.

error running the app

Tried to run the code and am getting an error template not found, changed the BASE_DIR in settings.py file from build to public where the index.html template is and when I run the server it just shows the page title 'justchat' nothing else am really stuck please help me

Websocket are not authenticated

As far as I understand, the WebSocket consumer does no authentication. So Any WebSocket connection will be accepted and can send messages, am I right?

So, any middleman with the chatId and username can connect and send messages on behalf of that user.

Can not access the chat page....

Can not access the chat page....whenever I get git clone I can not access the chat only the Django Rest Framework page and not the chat itself.
