Django app on Cloud Run infinite redirects (301)
I am trying to deploy a Django app in a container to Cloud Run. I have it running well locally using Docker. However, when I deploy it to Cloud Run, I get infinite 301 redirects. The Cloud Run logs do not seem to show any meaningful info about why that happens. Below is my Dockerfile that I use for deployment: # Pull base image FROM python:3.9.0 # Set environment variables ENV PIP_DISABLE_PIP_VERSION_CHECK 1 ENV PYTHONDONTWRITEBYTECODE 1 ENV PYTHONUNBUFFERED 1 # Set work directory WORKDIR /code # Install dependencies COPY requirements.txt requirements.txt RUN pip install -r requirements.txt && \ adduser --disabled-password --no-create-home django-user # Copy project COPY . /code USER django-user # Run server CMD exec gunicorn -b :$PORT my_app.wsgi:application I store all the sensitive info in Secrets Manager, and the connection to it seems to work fine (I know because I had an issue with it and now I fixed that). Could you suggest what I might have done wrong, or where can I look for hints as to why the redirects happen? Thank you! -

Why is my web service trying to redirect to a url that does not exist?
Basically, I have a web service that I am trying to build using Django. While working on the user LogIn, I ran into a confusing error. If the user is None (in my code, this means that the password or username does not match an existing one), then the user should be redirected to the LogIn page again, wich has a url path of /accounts/login, however, is instead sent to /accounts/login/login This is the code that controls the user LogIn def logIn(request): if request.method == 'POST': username = request.POST['username'] password = request.POST['password'] user = auth.authenticate(username=username, password=password) if username is not None: auth.login(request, user) return redirect('/') else: return redirect('/accounts/register/') else: return render(request, 'logIn.html') This is the urls file inside the app from django.urls import path from . import views urlpatterns = [ path('', views.Empty), path('register/', views.register), path('login/', views.logIn) ] and this is the main urls file in the project from django.contrib import admin from django.urls import path, include urlpatterns = [ path('admin/', admin.site.urls), path('', include('ControlApp.urls')), path('accounts/', include('Accounts.urls')) ] Here's the full code in case it helps I tried changing removing completely the redirect instruction from the logIn function, however, evenm then the user was getting redirected to /accounts/login/login I assume there … -
Django template with forloop. Exception Type: IndexErrorm, Exception Value: pop from empty list
I have a web page with essays. Each essay (on its own sub-page) can have multiple videos from another model (linked with many-to-many relations). When I had - in the past - one video in a subpage with a particular essay (with a different column related to the video, in the same model: 'one-to-many model', now hashed in my models.py) then I used to be able to invoke the video in my essay page with: <p>{% video essay_videos.video.video_item_url %}</p> But now when I try to invoke a list of videos, with this code: <ul> {% for vid in essay_videos %} <li>{{ vid.video_item_url }}</li> {% endfor %} </ul> I'm getting a list of URLs - that's ok, but, when I try to use the embed-video tag (like before): <ul> {% for vid in essay_videos %} <li>{% video %}{{ vid.video_item_url }}{% endvideo %}</li> {% endfor %} </ul> or <ul> {% for vid in essay_videos %} {% video %} <li>{{ vid.video_item_url }}</li> {% endvideo %} {% endfor %} </ul> or <ul> {% video %} {% for vid in essay_videos %} <li>{{ vid.video_item_url }}</li> {% endfor %} {% endvideo %} </ul> ...In all cases, I've got Exception Type: IndexErrorm, Exception Value: pop from empty … -
django-money object not limiting decimal fields
I'm using django-money for all currency fields in an app I'm building. According to the documentation the default CURRENCY_DECIMAL_PLACES is 2, and I am explicitly calling it in my settings.py file as well. However, when I am checking a remaining balance on an order it is returning a Money object, but showing all the decimal places instead of just 2. In [2]: order.remaining_balance Out[2]: Money('0.002500000000', 'USD') Is there a reason it isn't restricting it to only the 2 decimal places that I am wanting? In the templates it is only showing two decimal places, but in my views.py file or the shell it renders the full decimal places. I've set the CURRENCY_DECIMAL_PLACES to 2, but I'm getting back more than 2 decimal places. -

Django Websocket is not sending instant within group
I have a websocket that should send messages very x seconds. I am connecting to the socket from two clients. THe socket should send the message to both when one of them sends a start message but only the one which doesnt started is getting the message every x seconds. The one which send is getting all messages after all the time passed This is the loop. The normal send is getting send instant to one that initialized the send (i used this for now as a half fix). My problem is that the send to the group is not send every x second as it should. Only the other connected client are getting it every seconds.

Django Allauth Email Verification ( not effective after signup ) .. works after first login

DJStripe create subscription for user after logging in
When a user signs up for the service, a stripe subscription should be automatically created when the user logs in. To achieve this, I added the following code snippet to my middleware. stripe_customer, _ = Customer.get_or_create(subscriber=user) user.update_stripe_customer(update_name=True) subscription = stripe.Subscription.create( customer=stripe_customer.id, items=[{"price": "price_id"}], metadata={ "user_id": user.id, "product_type": "type1", }, trial_period_days=trial_period_days, cancel_at_period_end=True, currency="eur", ) # Option 1 Subscription._get_or_retrieve(subscription.id) # Option 2 Subscription.sync_from_stripe_data(subscription) Both options work locally, also another option using djstripe. In the moment, I deploy my app to the staging enviroment, the subscription is being created but not saved into the database. As the staging enviroment uses transactions, I also tried to call the signup action after the transaction has been finished but the problems continues. What happens, stripe is being called, a customer and a subscription created but not saved into the database. -

Django Form fields changing after page refresh

When pressing F5 to reload the page, the unsolicited fields do not appear. I suspected cache, but disabling the caches did not cause changes.

javascript fetch request(PUT) for formdata doesnt work when i specify the Content-type in the headers param
this is the request: let form = document.querySelector('form') let data = new FormData(form) fetch("http://127.0.0.1:8000/products/", { method: 'PUT', body: data, headers: { 'X-CSRFToken': "{{ csrf_token }}", } }) .then((response) => response) .then((data) => console.log(data)); So when I specify the Content-type in the headers param(doesnt matter if multipart/form-data, urlencoded etc. I tried it all) it doesnt work, but when I omit the content-type my backend(django) can process the request and the image is uploaded to the server and the rest of the formdata is being processed too. I looked at the network tab in ChromeDev Tools and the header is set to multipart with a strange ending: "multipart/form-data; boundary=----WebKitFormBoundary1QDdcJugTKrSMnto", does someone know the reason for this strange behavior? enctype is not set in the form element Thanks in advance <3 the content type header is set automatically. -

Access django url without apache http basic authentication
I'm working on a Django 3.2 project which is hosted using Apache 2.4 server. The user authentication in this project is handled using HTTP Basic Authentication configured using LDAP. I have implemented a sign up feature for new users. For that I have created the necessary form, view, template and url pattern in the Django project. The urlpattern to visit the sign up form is /signup. My goal is to make the sign up urlpattern accessible to anyone i.e. prevent the Basic Authentication from showing when the sign up urlpattern is requested by user in the browser. JFI, the complete Apache configuration is already complete and works already. To achieve this, I have used the "LocationMatch" directive in the Apache configuration within the VirtualHost directive: ... <LocationMatch "^/signup$"> Require all granted </LocationMatch> ... With this the Basic Authentication is removed when /signup URI is requested, but the server always redirects to another url which ultimately requires authentication hence giving the basic auth pop-up. $ curl -I https://*****.com/signup HTTP/1.1 302 Found ... I have tried to redirect the request explicitly to /signup whenever the is /signup. This ends up in an endless loop of redirections. RewriteEngine on ... RewriteRule ^/signup$ /signup … -

Control an asynchronous routine elegantly in Django
Using Django, I need to poll updates from a GraphQL subscription and being able to turn the updates on and off. My implementation uses websockets package wrapped in an async function to poll updates from a local container providing a GraphQL subscription and stores them in Django database. I need to find a way to control this polling feature with an on/off GraphQL mutation that would start or stop the readings and database updates. I've tried using celery by starting a celery task upon Django apps.py ready() method, but I think it became overkill and I ended up having multiple tasks being too hard to manage.
