Unable to fetch model data in Django Async conusmers . working in channels and websockets

Asked 2022-Mar-21 at 17:10

I am working on a chat application with channels and websockets using async programming. I am unable to get the model data / object in consumers.py but able to create one .

As someone in the group sends the message , it is echoed to the whole group but not saved and thus is flushed after the page is refreshed . I want to save the message in the database as the message is sent to the group using websockets . But I am facing problem.

This is my consumers.py

ANSWER

Answered 2022-Mar-21 at 17:10

Actually there was no problem in the program . The problem was in the return data type of the json data via websockets . When the messsage was sent via websockets , it was sent in the form of json data , and the key value pair had string type in it . Thus , when the data was sent , the extra quotes were also taken in account and the data instead of being just a username of type string , was actually in the form of a string with extra quotes at the end . For example -> The username of the current user is xyz123 , then it was sent in the form of "xyz123" . The solution was just to truncate the last two quotes , and we done .

here's the working code.

Asked 2021-Dec-22 at 08:43

I use djangorestframework-simplejwt.

I have two Django Projects sharing the same database.

One is django-restframework

One is django-channels

django-restframework login will get JWT

I cannot verify successfully in django-channels

I wrote the test function

restframework verify ok ...

ANSWER

Answered 2021-Dec-22 at 08:43

Because i don't know how jwt verifies

Now I found that the verification method is SECRET_KEY in settings.py

As long as different projects use the same SECRET_KEY.

There is no problem with JWT authentication.

Django app using Graphql and Channels package throws Exception inside application: 'NoneType' object has no attribute 'replace'

Asked 2021-Aug-23 at 14:46

I've got a Django app that uses graphene to implement GraphQL and I've got everything setup and working but I now have an error in the console which has popped up suddenly and although it doesn't break anything, at least from as far as what I can tell, it does keep showing up in the console and I'd like to fix it.

I'm quite new to Django so I'm not able to figure out where this is coming from. It looks like it's coming from the channels package.

This is the error in its entirety that happens immediately after the server runs and then again after every request is made.

...

ANSWER

Answered 2021-Aug-23 at 14:46

TlDR - Upgrade the channels package to 3.0.4.

Details:-

I've narrowed down the issue to it being caused by ALLOWED_HOSTS having anything other than ['*']. So if I had a specific list of allowed domains such as ['localhost', '0.0.0.0'], it throws an exception and it actually prevents subscriptions from working.

The culprit is the use of 'AllowedHostsOriginValidator' of the channels package that somehow breaks when using Python 3.8. The issue is documented here

Fix has been added to version 3.0.4 of the channels package. Just upgrade the package it should work just fine.

QUESTION

Django Channels TokenAuthMiddleware Unable to find Token in Database

Asked 2021-Jul-20 at 13:56

I'm so confused why my middleware isn't correctly getting a user based token query by key.

First I checked in my consumer, however the user in self.scope was an AnonymousUser (seen below in the code). This is reiterated when I set a foreign key in my receiver function, which raises the error: ValueError: Cannot assign "": "ChatMessage.user" must be a "User" instance.

Hence, I'm assuming the error is my middleware. I experimented with putting a print statement in middleware.TokenAuthMiddleware.__call__ after the get_user function is awaited and called, however, unexpectedly, the function returns an AnonymousUser. Both the user and the associated Token are created in the testcase's setUp and it's that token's key which is passed to the function.

Is the token string becoming malformed in format_querystring? The function is tested and passed, so I do not believe the token is becoming malformed there.

One thought is because the user and the token are being created in setUp, which is not async, it somehow is not aligned with the processes of the database look up in get_user. However changing that to async and wrapping the database calls in database_sync_to_async did not fix it, so I don't believe it's that either.

One idea is that not setting up my application correctly in the test, however based on their tests, it seems correct.

using Django's TransactionTestCase solved the issue. TransactionTestCase is further explained here.

The questions Database errors in Django when using threading, Test database not keeping data during Django Channels Pytest test, and Django channels 2, accessing db in tests led me to a working solution.

I don't fully understand why forcing transactions to be atomic is the solution, but oh well.

QUESTION

Django Channels - Websocket connection failed

Asked 2021-Jun-21 at 16:46

I am currently trying to setup my Django Channels chat app, and I have followed the Docs to the best of my understanding - Obviously when something doesn't go right, there's always a solution, but I am just having difficulties working out where I've gone wrong with getting this to work.

So far I have installed Django Channels, correctly configured my channel_layer within settings.py, I have referenced the docs and other online tutorials with creating my consumer.py file, utils.py, views.py and chat.html template file.

I have also configured nginx, gunicorn, daphne and redis and I can confirm that all of these services are running. I have installed LetsEncrypt and have allowed the SSL port (443 for https connections).

I am currently accessing my Django website on a live production server like this: https://mydomain:8001 and the direct link to my chat is configured as https://mydomain:8001/messenger

(I have allowed port 8001 through my firewall)

Here are the status messages I am getting from the chat page:

I think the issue is in the configuration. In the nginx, you have to specify the URL prefix, not the protocol, there is also no need to add both ws and wss. The nginx config must look similar to this
