Websocket 404 error after deploying to the domain
I setup websockets (chat module) in my Django application, it is working fine on my local machine but when I deployed my app to amazon ec2 instance with containerization it says 404 Not Found while testing via the postman. My ASGI container logs also say the same: WARNING Not Found: /chat/1/ IP:47942 - - [XX:XX:XX] "GET /chat/1/" 404 4479 Note that there is no problem with Docker containers - I tried on containers too on my local machine, and it worked. I have asgi.py import os from django.core.asgi import get_asgi_application from channels.routing import ProtocolTypeRouter, URLRouter from django.urls import path os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'cruze_development.settings') application = get_asgi_application() from cruze_development.middleware import JWTAuthMiddleware from cruze_development.consumers import ClubFeedConsumer, RideLocationConsumer application = ProtocolTypeRouter({ "http": application, "websocket": JWTAuthMiddleware( URLRouter([ path('ws/chat/<str:room_name>/', ClubFeedConsumer.as_asgi()), path('ws/location/<str:ride_id>/', RideLocationConsumer.as_asgi()), ]) ), }) wss://mydomain.com/ws/chat/1/ I am trying with both ws and wss Help me solve it, man! -
ODBC Driver 18 Heroku Django connection
I have database (Azure SQL) which I need to interact with on my Django backend and also I do have credentials like client id, client secret, tenant id. So basically I'm connecting via Azure App to this database. I run into a problem when Heroku on its side doesn't have ODBC Driver 18 installed so I followed https://github.com/matt-bertoncello/python-pyodbc-buildpack the buildpack which pre-installs ODBC Driver 17 however I faced another issue with that where my openssl version is 3.0 or something but it requires maximum of 1.1, anyway if this issue is settled I still left with ODBC Driver 17 version which makes impossible to connect via Azure APP credentials, so only ODBC Driver 18 would work for me. My question is simple, does anyone tried to do the same with heroku and Azure SQL, can you just share steps you take to connect to this database, also are you using VPN for backend? Cuz it seems like proxies can't handle the connection for db as well. Lmao, so many questions asked sorry about that, hope to find the answer here. Stackoverflow seems to be almost empty on that sort of questions, read around 10 posts related to this topic none … -

Account Merging with Google Login and Normal Registration
In my Django project, I have both normal registration and Google login. If a user registers normally and provides their email, and then tries to log in with Google using the same email, the classic login screen appears. What I want is this: If a user logs in with Google first and then tries to log in with the same email via normal registration, or if they register normally and later try to log in with Google using the same email, I want both methods to lead to the same account. In other words, regardless of whether they log in with Google or normal registration, the user's information should be merged and they should access the same account in both cases. socal login sections in settings.py: SOCIAL_AUTH_GOOGLE_OAUTH2_KEY = '<722444511487-2i7e9u3urlugcp2cp6slp09jjg7kgdg3.apps.googleusercontent.com>' SOCIAL_AUTH_GOOGLE_OAUTH2_SECRET = '<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>' SOCIALACCOUNT_LOGIN_ON_GET=True ACCOUNT_UNIQUE_EMAIL = True EMAIL_VERIFICATION_METHOD = 'email' # settings.py EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend' EMAIL_HOST = 'smtp.gmail.com' EMAIL_PORT = 587 # TLS GENELLİKLE 587 PORTUNU KULLANIR SSL İSE GENELLİKLE 465 PORTUNU KULLANIR EMAIL_USE_TLS = True # TLS SSL'E GÖRE DAHA MODERN VE GÜVENLİDİR EMAIL_HOST_USER = '' EMAIL_HOST_PASSWORD = '' views.py: def loginUser(request): if (request.user.is_authenticated): messages.error(request,"Giriş Yapılıyken Giriş Yapamazsın!") return redirect("index") form = LoginForm(request.POST or None) if (form.is_valid()): login(request,form.cleaned_data["user"]) messages.success(request,"Başarıyla Giriş … -

How Can a Beginner Web Developer Start Getting Clients Without Prior Experience?
I'm a 16-year-old self-taught web developer. I’ve been learning technologies like UI/UX, Bootstrap, and Django. I want to start earning money by getting clients, but I’m facing some challenges: Lack of Experience: Many freelancing sites require prior experience, but I don’t have any yet. How can I overcome this chicken-and-egg problem? Finding Clients: I don’t know where to look for my first client or how to convince someone to hire me without a portfolio of work. I’ve been trying various freelancing platforms, but I keep running into the same issue: most clients want experienced developers. For those who’ve been in this situation, how did you find your first client? Do you have advice for someone like me who is just starting out? Thank you in advance! -

Django or Different Framework?
I currently have a Django application, which is using Datatables. I'm thinking about creating views to load data into the datatable but load different data on the same page (into that same datatable). This way the page doesn't have to keep refreshing for each category. My question is, doing this, I won't have much need for the Django Template other then some basic things. Is this normal to do in Django or should I be using a different framework? -
Inconsistent URL error in Django from following along to Beginner YT tutorial
As you can see in the first screenshot, /products/new isn't showing up as a valid URL although I followed the coding tutorial from YouTube exactly. For some reason there's a blank character before "new" but no blank space in the current path I'm trying to request. I don't know if that's normal or not. I'm using django version 2.1 if that matters The URL does work for products/salt/. What's weird is the URL used to be products/trending/ but I got the same error so I randomly changed the URL to salt and it started working for me.

Django throwing a 403 error (CSRF Cookie not set) despite token being passed in request header from React/Vite app
So my situation is that I have a form in a react frontend trying to post some data to a Django backend. When the Django view is CSRF exempt, all functionality is fine. However, when I remove the exemption decorator, Django always throws a 403 error - CSRF cookie not set. I have verified that there is indeed a token being passed in the request header, but for some reason the 403 error is still being thrown. I found a similar thread with a similar issue (Django and React: csrf cookie is not being set in request header), however from what I saw, I was already using the suggested fixes. Firstly, I have a route set up to initially pass the CSRF token to the frontend, as follows: @ensure_csrf_cookie def get_csrf_token(request): csrf_token = get_token(request) return JsonResponse({'csrfToken': csrf_token}) Along with the following JS to request the token: const getCSRFToken = async () => { const apiUrl = import.meta.env.VITE_API_URL; const response = await fetch(`${apiUrl}getCSRFToken/`, { method: "GET", credentials: "include", }); const data = await response.json(); return data.csrfToken; }; useEffect(() => { // Fetch CSRF token on component mount getCSRFToken().then((csrfToken) => { Cookies.set("csrftoken", csrfToken); // Store the token in a cookie }); }, … -
Django SMTP Email Issue: Gmail App Password Not Working + Model Not Updating
I am working on a Django project where I need to send emails using Gmail’s SMTP server. However, even though I have set up the SMTP settings correctly and used the App Password from Google, I’m still encountering issues when trying to send emails. Additionally, the model where I store the review replies isn't updating, even after I attempt to save data to it. Here’s the full setup: What I’ve Tried: 1.SMTP Settings in settings.py: EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend' EMAIL_HOST = 'smtp.gmail.com' EMAIL_PORT = 587 EMAIL_USE_TLS = True EMAIL_HOST_USER = 'myemail@gmail.com' EMAIL_HOST_PASSWORD = 'myapppassword' # Gmail App Password DEFAULT_FROM_EMAIL = 'myemail@gmail.com' Views: In my view, I allow vendors to reply to product reviews. When a vendor replies, the reply is saved in the ProductReview model and an email should be sent to the customer.

Can I create a many to many relation using a junction table with a junction table
I want to create a m2m relation between two tables and one of the table is a junction table for m2m relation. So basically, I have 3 tables and 2 can be joined using a m2m. But in order to join three tables, I have two options, one is to create a m2m with the third table and the already created junction table and the other approach is to create a table which has foreign key of all the three tables. Which of the above approach is suitable. The two approaches to implement table with relation to three tables are: CREATE TABLE PromoPrizeScreen ( id SERIAL PRIMARY KEY, prize_cap INTEGER DEFAULT NULL, prize_used INTEGER DEFAULT NULL, promo_prize_id INTEGER NOT NULL, screen_id INTEGER NOT NULL, FOREIGN KEY (promo_prize_id) REFERENCES PromoPrize (id) ON DELETE CASCADE, FOREIGN KEY (screen_id) REFERENCES Screen (id) ON DELETE CASCADE ); CREATE TABLE PromoPrizeScreen2 ( id SERIAL PRIMARY KEY, prize_cap INTEGER DEFAULT NULL, prize_used INTEGER DEFAULT NULL, promo_id INTEGER NOT NULL, prize_id INTEGER NOT NULL, screen_id INTEGER NOT NULL, FOREIGN KEY (promo_id) REFERENCES Promo (id) ON DELETE CASCADE, FOREIGN KEY (prize_id) REFERENCES Prize (id) ON DELETE CASCADE, FOREIGN KEY (screen_id) REFERENCES Screen (id) ON DELETE CASCADE ); I … -
