Websocket not receiving messages from Django Channels server websocket
I'm currently working on a project using Django Channels for WebSocket communication. However, I'm facing an issue where the WebSocket connection is established successfully, but messages are not being received on the client side. WebSocket connection is established without errors. I've verified that the Django Channels server is sending messages. However, the client-side WebSocket does not seem to receive any messages. my asgi.py is import os from django.core.asgi import get_asgi_application from channels.routing import ProtocolTypeRouter, URLRouter from channels.auth import AuthMiddlewareStack from channels.security.websocket import AllowedHostsOriginValidator import transposys_main.routing import django os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'transposys_main.settings') django.setup() application = ProtocolTypeRouter({ "http": get_asgi_application(), "websocket": AllowedHostsOriginValidator( URLRouter( transposys_main.routing.websocket_urlpatterns ) ), }) my consumer.py is import json from channels.generic.websocket import AsyncWebsocketConsumer import logging logger = logging.getLogger(_name_) logger.setLevel(logging.DEBUG) class DepartmentCreatedConsumer(AsyncWebsocketConsumer): async def connect(self): logger.info(f"WebSocket connected: {self.channel_name}") await self.accept() async def disconnect(self, close_code): logger.info(f"WebSocket disconnected: {self.channel_name}") async def receive(self, text_data): logger.info(f"WebSocket message received: {text_data}") try: text_data_json = json.loads(text_data) message_type = text_data_json.get('type') message = text_data_json.get('message') if message_type == 'department.created': logger.info(f"New Department: {message}") except json.JSONDecodeError as e: logger.error(f"Error decoding JSON: {e}") async def department_created(self, event): try: logger.info(f"Department created event received: {event['message']}") await self.send(text_data=json.dumps({ 'type': 'department.created', 'message': event['message'], })) except Exception as e: logger.error(f"Error sending WebSocket message: {e}") routing is from django.urls import re_path from … -

Creating a table to display rows from a database
I'm trying to create a table that will display the rows of a database called patients and I have created this using Django as the back-end and react as the Front-End. When I try to implement the code I have created thus far the only thing I'm seeing on the webpage is my table header. It should be noted that I have checked sqlite studio and there is data stored in the table. I've checked on PostMan and my Get, POST,PUT, and DELETE methods are all working fine and do what I intend them to do. I'm using Firefox as my browser and I've checked the network tab under inspection, but nothing is being sent to the back-end. I will attach my initial attempt at the front-end webpage import React, {Component} from 'react' export class ViewPatients extends Component{ constructor(props){ super(props); this.state = { patient: [], }; } fetchPatients = () => { fetch('http://127.0.0.1:8000/patient') .then(response => response.json()) .then(data=> { this.setState({patient:data}); }) .catch(error => { console.error("Error Fetching Patients") }); }; componentDidMounted(){ this.fetchPatients(); // this.refreshList(); } render(){ const { patient } = this.state; return( <div> <table> <thead> <tr> <th>ssn</th> <th>address</th> <th>age</th> <th>gender</th> <th>race</th> <th> medical history </th> <th>occupation</th> <th>phone number</th> <th>username</th> </tr> </thead> … -
How to update Django url (to include data/param) after POST
I have a search form (place names) on my home page with an auto-complete dropdown on the search input field. When the user presses enter after selecting an item in the search box the form does a post. When the results return I still have the same url (https://mywebsite.com). How do I get the selected search entry (a location name) to appear in the url so users can book mark it for later use? eg https://mywebsite.com/mylocation I have got the GET code working to get the location in the url - just don't know how to update the url to add the location string after the search form post. I am new to Django so really winging it. Have searched but found no discussion on this even in the Django docs. -
Removing user tags in django
I have been using taggit feature in django for hobbies . Each user can add his hobbies in his profile and tags will be created like tennis or watching movies. I have created a cloud to show him the tags that he has already added : <div class="rounded-tag-container"> {% tag_edit person_id=person.id %} </div> this is also html for this cloud: {% for tag in tags %} <span class="rounded-tag"> <a href="#" style="color:blue;"> {{ tag.name }} </a> <span class="close-button" onclick="removeTag(this, '{{ tag.name }}')"> <strong>×</strong></span> </span> {% endfor %} <script> function removeTag(element, tag_name) { element.parentNode.remove(); $.ajax({ type: 'POST', url: '/hobbies/' + person_id + '/', data: { tag_name: tag_name, csrfmiddlewaretoken: csrftoken }, success: function(response) { console.log(response); }, error: function(error) { console.error('Error deleting tag:', error); } }); } also In my hobbies view I defined tag_name: tag_name = request.POST.get('tag_name') if tag_name : try: person.tags.remove( tag_name) messages.success(request, 'Tag deleted successfully') except Tag.DoesNotExist: messages.error(request, 'Tag not found') else: messages.error(request, 'Tag name not provided') when the user clicks on the close button of each tags,it will be removed from the client side and then clicks on submit,it must remove the tag in post request from db, but it does not remove it from database! -

Celery redis reduce freqeuncy of BRPOP messages

Django "request.user" always returns "AnonymousUser" even though sessionid gets added and is valid
So I made a discord oauth2 login without using a User model like AbstractUser or AbstractBaseModel, when I first made it a month ago, it worked fine and the login worked flawlessly! (Profile loaded, username shown, etc.) I don't know what I changed a week ago, but it no longer works. The custom authentication works and authenticate() returns a new DiscordUser model, then it gets passed to login() with the custom backend argument. The sessionid gets saved in the cookie storage when I check it. When I also check the DB, the sessionid is there and therefore a valid sessionid. Yet when I print out the request.user or request.user.is_authenticated I always get AnonymousUser and False. I don't understand.

Sending the output of two filters in one querystring to filter a django model
I have two filters. I have used pokemon as the example: Filter A: filters the pokemon trading card sets e.g. Base set, Fossil, Jungle Filter B: Filters the pokemon stats, e.g. pokemon types, name of pokemon. Those two filters have two submit buttons, I want them to work together. If I hit the submit for filter B it sends: ?name=Bulbasaur&type= If I hit the submit for filter A it sends: ?sets=Jungle What I want is: ?name=Venusaur&type=&sets=Fossil I'm using the module django-filters, I construct a FilterSet class for each filter that I initiate in the view. pokemon_sets = PokemonSets.objects.all() pokemon_filter = PokemonSetsFilter(request.GET, queryset=pokemon_sets) sets = pokemon_filter.qs.values_list('key_id', flat=True) pokemon = PokemonDatabase.objects.filter(sets__in=sets) pokemon_filter = PokemonFilter(request.GET, queryset=listings) Any insight will help greatly!

How to dynamically set the access token expiration in Django Rest Framework Simple JWT?
I am working on a restful web application using Django Rest Framework and need to implement a mechanism to check every 15 minutes if the user has been active in order to extend their token expiration. If the user has not been active, their access token should become invalid. I am using Djoser in conjunction with Simple JWT as the authentication backend. Can someone provide guidance on how to achieve this? Thank you. I have tried creating a custom middleware to track the user's activity for the last 15 minutes but do not know how to effectively manage the user's jwt access token based on the user activity. -

But I got a blank screen when I made an API call using postman -
Failed authentication for Google Sheet and Django running in Apache server
I'm implementing a Django application that uses a Google Sheet as database, and is hosted with Apache in a Rocky Linux server. To test the integration between Django and Google Sheet, I have followed Tom Dekan Tutorial. And to configure the Django application to run with Apache, I have followed the official Django Tutorial.
