who will serve ASGI and WSGI when i add daphne?
when i add daphne in INSTALLED_APPS how will it work ? does it work itself to serve WSGI and ASGI ? or Does it work alone to serve ASGI only ? and Gunicorn still working to serve WSGI ? if daphne works alone to serve ASGI only, and Gunicorn works alone to serve WSGI only... that means i am running two servers in the same time . right ? i have read the document of Channels and ASGI ... but i did not find any thing talks about this thing .. and how will it act >> or if does it take everything and serve them all. if thet so, then i have to deploy my project on a server and run daphne only right? channels document.

Deploying Django project in an Amazon EC2 Ubuntu instance
I have developed a Django website and hosted the application in an Amazon EC2 instance. AMI name: ubuntu/images/hvm-ssd/ubuntu-jammy-22.04-amd64-server-20231207 Instance type: t2.micro I run the project following these steps: SSH into the EC2 instance from my terminal. I locate into the proper django project folder. I run this command: python3 manage.py runserver 0.0.0.0:8000 Now, following these steps, I'm able to run the project and it works fine. But when I close the cmd opened in my local PC that I used to SSH into the EC2 instance and to run the application, then the application doesn't work anymore. My aim would be to simply run the django project from my cmd once (of course after having SSH to the EC2) and then close my laptop and having the application still alive. Do you know how can I do this? -

How to connect xhtml2pdf - pisa with the Cyrillic alphabet?
How to connect xhtml2pdf - pisa with the Cyrillic alphabet? I have a code that generates a PDF document, but if the form fields contain Cyrillic, then black squares are displayed in the PDF document. I read a lot of information on the Internet on how to make friends with the Cyrillic alphabet, but not a single answer saved my situation. I placed a font that supports Cyrillic in the static folder, static/fonts/(font name).ttf. I registered this absolute path according to the instructions. I used call_back, but that didn't help either. Perhaps I'm doing something wrong. Please help! Below is my code, if anyone knows how to fix this situation, please make changes to my code and tell me where my mistake is. I will be very grateful. Thank you in advance! `def convert_to_pdf(template_name, **context): template = get_template(template_name) html = template.render(context) result = BytesIO() pdf = pisa.pisaDocument(BytesIO(html.encode("UTF-8")), result, encoding="UTF-8") result.seek(0) response = HttpResponse(result.getvalue(), content_type="application/pdf; charset=utf-8") response["Content-Disposition"] = 'inline; filename="output.pdf"' return response` The example shows my initial code that generates a PDF document. -
Django Test: how to simulate LookupError for django_app.get_model()
I need help to implement a test for my Django app. This is a snippet code from my serializer, that I want to test: try: app_config = django_apps.get_app_config(BcConfig.name) app_model = django_apps.get_model(app_label=app_config.name, model_name=type_model_name) recording = app_model.objects.create(**recording) except LookupError: recording = None as mentioned in Django docs, Raises LookupError if no such application or model exists. How to simulate the LookupError programmatically? I have tried to remove the listed model using ContentType, but django_apps.get_model() was still working. I have tried to remove the model using SchemaEditor, but not working properly for testing in SQLite. I still can not find how to delete the model or disable the Django app programmatically. I appreciate the help. Thank you. -

Data Fetch Failure from Django REST API using useFetch in Nuxt.js: Different Behaviors on Reload and Code Editing
I'm developing with Nuxt.js and attempting to fetch data from a Django REST API. I'm encountering several issues with the following code: <template> <div> {{ posts }} </div> </template> <script setup lang="ts"> const { data: posts, pending, error, refresh } = await useFetch('https://localhost:8000/api/posts/') console.log(posts, error) </script> Here are the problems I'm facing: When using useFetch to retrieve data from the Django REST API, an error occurs. Specifically, the following log is output: Proxy(Object) {mountains: Error: [GET] "https://localhost:8000/api/posts/": <no response> fetch failed at createError (…} If I edit and save the Vue code while the page is displayed, the data loads correctly, and I can see the requests in the server logs. However, when I reload the page, the data does not load. There is no record of the request in the server logs. If I change the URL to https://fakestoreapi.com/products, the data is fetched correctly even on page reload. Could you advise on why the data doesn't load upon page reload and how I might resolve this? Also, if you have any insights into why the problem doesn't occur with a different URL, that would be very helpful. -

Auth0 - How to get userID ? StatusCode400 Error
Happy Sundays everyone. Note: Setup is Django-Rest. So I was trying to get user ID because I am going to check the user's roles in the login, and decide whether let them in or not. So currently I can get some information as id_token = token.get('id_token') jwk_set = oauth.auth0.fetch_jwk_set() user_info = jwt.decode(id_token, jwk_set) print(user_info) However, this information has 'nickname, name, picture, email' and so on. Therefore I tried, def get_user_id(): import http.client conn = http.client.HTTPSConnection("cageda.eu.auth0.com") headers = { 'authorization': "Bearer {settings.SOCIAL_MANAGEMENT_TOKEN}" } conn.request("GET", "/api/v2/users/USER_ID", headers=headers) res = conn.getresponse() data = res.read() print(data.decode("utf-8"))``` However, this is returning as: {"statusCode":400,"error":"Bad Request","message":"Bad HTTP authentication header format","errorCode":"Bearer"} I am totally stucked. A help would be a lifesaver. -
django web app accessed by multiple users
I'm trying to implement a web based quiz application I'm currently using django and html / JavaScript – only running on localhost so far (python manage.py runserver) For one single user, the quiz is working fine, but multiple users are not able to play individually atm. How do i handle concurrent access to the quiz? I considered using the request.session data structure but storing the complete quiz in there somehow feels wrong. And different users might play a totally different set of questions … Somehow I'd like to start a new thread each time a user access the webpage and starts the quiz (like I'd do it in some offline application), but im not sure if this is the right approach for web dev. I also read that this is maybe done by the real webserver, e.g. apache? Should I try to put the django app on apache? Also considered docker and started a small tutorial this morning. I can post some code ofc, or provide more implementation details if necessary but at the moment I need to get a basic understanding of web development best practices ;-) Scenario: User A starts quiz and answers the first 5 questions. User … -
why does any interaction with the django site direct you to the data addition form?
The task was given to develop a service for working with the restaurant database on django. Clicking on the corresponding buttons /fields of the data table should redirect to pages with edit/add/delete forms, but any interaction with the site redirects only to the page for adding new data. I've been trying to find the reason for this behavior for several hours, but nothing comes out. Below is the html markup of one of the pages, views, forms and URLs for working with one of the database tables. <body> {% include 'main/navbar.html' %} <h1>restaurants</h1> <div class="add"> <form method="post" action="{% url 'create_restaurant' %}"> {% csrf_token %} {{ form.as_p }} <button type="submit" class="btn btn-success">Добавить</button> </form> </div> <table class="table"> <ul></ul> <thead> <tr> <th>Address </th> <th>Phone number</th> <th>Delivery area</th> <th>Menu</th> <th></th> </tr> </thead> <tbody> {% for restaurant in restaurants %} <tr data-id="{{ restaurant.id }}"> <td class="editable-field" data-field="address">{{ restaurant.address }}</td> <td class="editable-field" data-field="phone">{{ restaurant.phone }}</td> <td class="editable-field" data-field="district">{{ restaurant.delivery_code.district }}</td> <td class="editable-field" data-field="menu">{{ restaurant.menu_code.name }}</td> <td> <button class="btn btn-danger" data-toggle="modal" data-target="#confirmDeleteModal{{ restaurant.id }}"> delete </button> <div class="modal" id="confirmDeleteModal{{ restaurant.id }}" tabindex="-1" role="dialog" aria-labelledby="confirmDeleteModalLabel" aria-hidden="true"> <div class="modal-dialog" role="document"> <div class="modal-content"> <div class="modal-header"> <h5 class="modal-title" id="confirmDeleteModalLabel">Confirmation of deletion</h5> <button type="button" class="close" data-dismiss="modal" aria-label="Close"> <span aria-hidden="true">&times;</span> </button> </div> <div … -

Issue with requests from Nuxt.js not adding cookies to Django server
I'm working with a Nuxt.js frontend and a Django backend and encountering an issue where cookies are not being set correctly after JWT authentication. My Nuxt.js app is running on https://localhost:3000 and the Django server is on https://localhost:8000.

Checking the Network tab, I noticed that the client-side isn't sending cookies.

AJAX is only getting data from last form in loop (Django)
I have a for loop that creates a number of forms on the page. I want to be able to submit these forms to another page without refresh using AJAX, however no matter which form I submit it only ever shows the value for the very last form. HTML code {% for post in post_list %} <form class = "f_form" id="f_form" name = "myForm" method="POST"> {% csrf_token %} {{ form.as_p }} <button type="submit" class="add">Submit</button> </form> {% endfor %} Jquery <script type="text/javascript"> $(document).ready(function(){ $(document).on('click','.add',function (event) { event.preventDefault(); var element = $(this); $.ajax({ url: '{% url "webscraper-favorited" %}', method: 'post', data:element.parent('.f_form').serialize(), success: function(data){ $('#message').html(data); } }); return false; }); }); </script> views.py def favorited(request): if request.method == 'POST': favorited = request.POST.get('favorited') favorites.append(favorited) print(favorited) context = { 'favorites' : favorites, } return render(request, 'webscraper/favorited.html', context) Right now the script is outside of the for loop but I previously tried putting it in the for loop as well. Instead of binding the script to the submit button I also tried binding it to the form id. That yielded the same result from my attempts. -

RTCPeerConnection Issue: Uncaught DOMException - Failed to execute 'setRemoteDescription' on 'RTCPeerConnection Django
I am encountering an issue with my WebRTC implementation in Django using Django Channels. The error I am facing is: "Uncaught (in promise) DOMException: Failed to execute 'setRemoteDescription' on 'RTCPeerConnection': Failed to set remote answer sdp: Called in wrong state: stable" After some research, I found a possible explanation for this error on Stack Overflow. It seems to be related to the fact that when a third user joins, it sends an offer to the two previously connected users, resulting in two answers. As a single RTCPeerConnection can only establish one peer-to-peer connection, attempting to setRemoteDescription on the second answer fails. The suggested solution is to instantiate a new RTCPeerConnection for every remote peer. However, I'm unsure how to implement this in my existing code.

How to rreturn a nested serialized data in Django
I created a Registration view in my Django app, but when I tried testing it, I wasn't getting the expected result. I'm trying to test my view with the data below, but I wasn't getting the expected result: { "email": "faruqmohammad@gmail.com", "first_name": "Faruq", "last_name": "Mohahmmad", "phone_number": "08137021976", "password": "#FaruqMohammad1234", "confirm_password": "#FaruqMohammad1234", "vehicle_registration_number": "ABJ145", "min_capacity": 20, "max_capacity": 50, "fragile_item_allowed": true, "charge_per_mile": 1000 } And the response I get is { "data": { "user": { "email": "mohammedfaruq@gmail.com", "first_name": "Mohammed", "last_name": "Faruq", "phone_number": "08137021976" }, "is_available": true, "vehicle_type": "TWO_WHEELER", "vehicle_registration_number": "", "min_capacity": null, "max_capacity": null, "fragile_item_allowed": true, "ratings": null, "charge_per_mile": null }, "message": "Rider registration successful" } {"vehicle_registration_number": "", "min_capacity": null, "max_capacity": null, "fragile_item_allowed": true, "ratings": null, "charge_per_mile": null} These values are set to the default value from the model even when I provided them And below is my model, serializer and views Model: class Rider(models.Model): user = models.OneToOneField( CustomUser, on_delete=models.CASCADE, related_name="rider_profile" ) vehicle_type = models.CharField(max_length=50, default="TWO_WHEELER") vehicle_registration_number = models.CharField(max_length=20, unique=True) is_available = models.BooleanField(default=True) min_capacity = models.PositiveIntegerField(null=True, blank=True) max_capacity = models.PositiveIntegerField(null=True, blank=True) fragile_item_allowed = models.BooleanField(default=True) charge_per_mile = models.DecimalField( max_digits=6, decimal_places=2, null=True, blank=True ) current_latitude = models.DecimalField( max_digits=9, decimal_places=6, null=True, blank=True ) current_longitude = models.DecimalField( max_digits=9, decimal_places=6, null=True, blank=True ) ratings = models.DecimalField(max_digits=3, decimal_places=2, …
