Efficient way to continuously consume messages from Redis Streams while being connected to Websockets through Django Channels
I have written a Django application to receive updates of long running tasks. I am using Redis as a channel layer for web-sockets and also making use of Redis Streams to store the updates of the tasks that are currently running. I have spawned a thread from connect method of WebSocket Consumer to run an infinite loop to continuously check for updates from Redis Consumer. This seems to be a hackish solution for what I am trying to achieve i.e. to remain connected to the websocket and also simultaneously receive updates from Redis Streams. This is my code for Websocket Consumer. As you can see, I am running an infinite loop to check for any new messages in the stream through Redis Consumer. import json from threading import Thread from asgiref.sync import async_to_sync from channels.generic.websocket import WebsocketConsumer from django.utils import timezone from redis import ConnectionPool, Redis from redis_streams.consumer import Consumer class ProgressStateConsumer(WebsocketConsumer): def __init__(self): self.task_id = self.task_group_name = None connection_pool = ConnectionPool( host="localhost", port=6379, db=0, decode_responses=True, ) self.redis_connection = Redis(connection_pool=connection_pool) self.messages = [] super().__init__() def connect(self): task_id = self.scope["url_route"]["kwargs"]["task_id"] self.task_id = task_id self.stream = f"task:{self.task_id}" self.task_group_name = ( f"task-{self.task_id}-{round(timezone.now().timestamp())}" ) async_to_sync(self.channel_layer.group_add)( self.task_group_name, self.channel_name ) thread = Thread(target=self.send_status) thread.start() self.accept() def … -

django-channels - group send does not call the function defined in "type"
I have this Consumer: class TableConsumer(AsyncWebsocketConsumer): async def connect(self): self.table_name = f'table_test' self.channel_name = f'channel_test' await self.accept() await self.channel_layer.group_add( self.table_name, self.channel_name ) await self.manage_new_game_video() async def manage_new_game_video(self): await self.channel_layer.group_send( self.table_name, {"type": "chat_message", "message": "message"} ) # Receive message from room group async def chat_message(self, event): print("test") message = event["message"] # Send message to WebSocket await self.send(text_data=json.dumps({"message": message})) for some reason, the print statement is never executed and I don't understand why. Why can that happen? Thanks. -

How to re-deploy Django changes in linux
My application is up and running on my server. I'm using linux Nginx and Gunicorn. I'm logging in to the server using ssh with private key.

Django: Is it a good idea to have two caches on one memcached instance?
I would like to have two caches with different timeouts on one memcached instance in my django 3 instance: CACHES = { 'default': { 'BACKEND': 'django.core.cache.backends.memcached.MemcachedCache', 'LOCATION': '127.0.0.1:11211', 'CACHE_KEY_PREFIX': 'default_cache', 'TIMEOUT': 300, }, 'custom': { 'BACKEND': 'django.core.cache.backends.memcached.MemcachedCache', 'LOCATION': '127.0.0.1:11211', 'CACHE_KEY_PREFIX': 'custom_cache', 'TIMEOUT': 3600 * 24, }, } I did not find an example which does this, so I`m not sure if something could go wrong with this. What do you think? Could there e.g. be a problem with django["cachename"].clear() command? -
proper way to import django base settings in production settings
I have seen alot of articles and videos about the best practices when it comes to managing django settings file. And almost of them talks about having a base settings base_settings.py and then environment settings, like development_settings.py, production_settings.py etc. usually in the dev and prod settings the base setting is imported into it like from project.settings.base import * I have also read that import * is a bad practice, so the question is WHAT IS THE RIGHT WAY TO IMPORT THE SETTINGS WITHOUT MESSING UP THE NAMESPACE. One of the warnings I get when running my test with pytest is the namespace warning, which I presume come from the * import see warning below when I run pytest ..\..\..\..\Miniconda3\envs\salary\Lib\site-packages\pkg_resources\__init__.py:2804 C:\Users\seven\Miniconda3\envs\salary\Lib\site-packages\pkg_resources\__init__.py:2804: DeprecationWarning: Deprecated call to `pkg_resources.declare_namespace('ruamel')`.

setting up Celery with RabbitMQ

How to implement login with Axios for multiple types of users?
I am building a web application ( with VueJs) that allows multiple types of users to login (e.g., regular users and administrators). I am using Axios to handle HTTP requests, but I am not sure how to implement login for multiple types of users. Certainly, here is the code with the provided section added to it: async submitForm() { const formData = { email: this.email, password: this.password } axios.defaults.headers.common["Authorization"] = ""; localStorage.removeItem("token"); await axios .post('http://127.0.0.1:8000/login', formData) .then(response => { console.log('response :', response.data) const token = response.data.auth_token this.$store.commit('setToken', token); axios.defaults.headers.common["Authorization"] = "Token " + token; localStorage.setItem('token', token); const toPath = this.$route.query.to || '/admin'; this.$router.push(toPath); }) .catch(error => { if (error.response) { for(const property in error.response.data) { this.errors.push(`${property}: ${error.response.data[property]}`); } } else { this.errors.push('Something went wrong. Please try again'); console.log(JSON.stringify(error.response.data)); } console.log(this.errors); }) }, Can someone provide guidance on how to achieve this with Axios? Any examples or code snippets would be greatly appreciated. Thank you! -
