Heroku Django websocket connection Failed
Heroku / Django / Channels Expert help needed. I am running a web app that uses websockets. Works great locally but fails on Heroku I am using ACM (Automated Cert Management) for SSL, it came with my dyno. Now the web console log says "websocket connection failed and log is saying ssl.SSLCertVerificationError so i tried to deal with it by adding following in my remote settings file: ssl_context = ssl.SSLContext() ssl_context.check_hostname = True CHANNEL_LAYERS = { "default": { "BACKEND": "channels_redis.core.RedisChannelLayer", "CONFIG": { "hosts": ({ 'address': 'rediss://some url', # 'ssl': ssl_context # }) } } } any ideas how i can run my code without the websocket failing -
Django test not returning proper status code
I was writing some tests for the authentication of my website to check to see if a user already exists a particular username or not. In my main code, it is supposed to return a status code of 409 and I tried to use that status code to assert the status code that I get from my response from the tests but the tests always give me a status code 200. In short, I can't get the response to have a status code of anything other than 200 while running tests, however when I try using it from the manage.py shell it works as expected. Here's the view: views.py def sign_up(request): if request.method == "POST": username = request.POST["username"] email = request.POST["email"] password = request.POST["password"] if User.objects.filter(username=username).count() != 0: messages.add_message(request, messages.ERROR, "An account already exists with that username") return render(request, "authentication/sign_up.html", status=409) else: user = User.objects.create( username=username, email=email, password=password) user.save() return render(request, "authentication/sign_up.html") Here's the test file. class SignUpTests(TestCase): def test_account_with_username_already_exists(self): response = self.client.post(reverse("authentication:sign_up"), { "username": "yasa.zaheen", "email": "yasazaheen728@gmail.com", "password": "12345678" }) self.assertEqual(response.status_code, 409) Here is the assertion error: D:\Aurora\aurora>manage.py test Creating test database for alias 'default'...

How to render Buy now view in django?

I have done that for cart means, when user will add products in cart only then he will be able to purchase products. But i wanna add a feature that will allow a user to buy a single product from the product_detail page, so without adding the product to cart he will be able to purchase.

How to test Django Querysets are equal using pytest-django
What's the best / most readable way to assert two querysets are equal? I come up with a few solutions: # option 1 assert sorted(qs1.values_list("pk", flat=True)) == sorted(qs2.values_list("pk", flat=True)) # option 2 (need to assert length first because set might remove duplicates) assert len(qs1) == len(qs2) assert set(qs1) == set(qs2) I know Django has a method django.test.TransactionTestCase.assertQuerysetEqual. Does pytest-django have something similar? I don't see it in the documentation. -

Stripe Webhook does not work when I changed it to my domain and https
I'm trying to configure Django App with Stripe. Webhook works well When setting the Endpoint URL using "IP address" and "http". Here is the Endpoint URL. http://3.129.xx.xxx/subscriptions/webhook/ But when I changed it to my domain and add "https", It does not work. Here is the Endpoint URL with my domain. https://mysite12345.com/subscriptions/webhook/ 1.HTTP statas code is "time out". 2.Event type is "checkout.session.completed" 3.The log is "200 OK" but "Webhook event" is failed, it retries again and again but still failed. 4.Of course, the domain is valid(I can access other pages) I wonder why IP address and "http" Endpoint URL works well but a domain name and "https" do not. When I changed "http" to "https" do I need to adjust something or am I missing something? I just mentioned the above settings in this question but still if more code is required then tell me I'll update my question with that information. Thank you -

How to implimanet backend of a Quiz Webiste?
I am planning to make a Quiz app using Django as a backend. Users would be able to make their own quizzes (mostly MCQ questions) and I needed help in figuring out the backend for it. So far my plan was to Have Users, Quiz, and Questions table. And use foreign Keys to connect Users to Their Quizzes and Quizzes to the Question. But this would result in way too many rows in the question table as Number of quizzes increases. Currently, I plan to use Django to make tables. I wanted to know if there is a way to probably make Tables dynamically or some other way to store quizzes data like JASON or some other way? If yes how would I be able to do so using django. I am open to any other suggestions. (not sure if required but I plan to use React for frontend) -
Why am I unable to migrate when other files use my models in Heroku?
For context, I have an application that works perfectly fine locally, after some fiddling with the database. It uses a react frontend, with a django backend for internal api calls. However, on a new, fresh download, with a new, fresh database, I always get an error saying relation "claims" does not exist, where Claims is the name of a table in my database, in the form of a model. I have been able to bypass this error by commenting out all code that uses the model, then slowly migrating every single table, one at a time, then uncommenting out the code that uses the model. This is incredibly tedious, but it works in a local environment. However, as I attempt to push this into production, I am using Heroku, and I am unable to make multiple commits in the same way, as it seems the database gets reset everytime there is a new update. Am I missing something? I feel as though there must be something I am doing incorrectly here, but I have not been able to find anything other than posts saying to reset all my migrations, and redoing the makemigrations command. This method hasn't worked for me … -

django live videos and real time chat with node js integration
I plan to build a web application that supports live, video, and real-time chatting Since I've never done anything like this before, I had to understand it well But with studying the topic, the situation became very complicated about what technique to use. I usually work with Django and React But with the research, people say this is very difficult. It is necessary to use Node I went to search for the integration of Node with Django and here I found a greater complexity. People say that you must use redis Pub/sub or that you work with the same database in both sides. Now I'm so distracted I don't see any document on what I want to reach The main question is: how can I integrate Node with Django to implement these functions You can help even with an untested idea or article, literally anything Thanks in advance -

Django running in kubernetes does not load jquery files
I have a django application which I am running using docker container inside kubernetes cluster.
