Django CSRF token not saving to browser cookies in Production environment, but working in Development environment
We have created a Django application to create a Shopify Application. We are having issues with out production environment we AJAX calls to the Django application are failing because the CSRF token is not being saved to cookies and therefore nothing gets parsed in the AJAX call headers. We have followed the Django documentation and added {% csrf_token %} in the <head> tag of our base.html file which all other html files reference. Because this is a Shopify App, this app is embedded into a iFrame in Shopify but I am not sure this is the culprit as its the same in our development environment. There does seem to be cookies in the browser from our domain, just not the csrf token: We can't find a solution to why this is happening. We have had to mark our functions dispatch with @csrf_exempt which we don't want to have to do moving forward. For example: @csrf_exempt def dispatch(self, *args, **kwargs): return super().dispatch(*args, **kwargs) -

Django - CSRF verification failed in Cloud Run
I am following this tutorial from Google codelabs. When trying to login to the admin panel, I am getting a CSRF verification failed. The tutorial is about deploying a fresh empty django project to Cloud Run. There's already a provided settings.py and I tried replacing it with this block to no avail: # SECURITY WARNING: It's recommended that you use this when # running in production. The URL will be known once you first deploy # to Cloud Run. This code takes the URL and converts it to both these settings formats. CLOUDRUN_SERVICE_URL = env("CLOUDRUN_SERVICE_URL", default=None) if CLOUDRUN_SERVICE_URL: ALLOWED_HOSTS = [urlparse(CLOUDRUN_SERVICE_URL).netloc] CSRF_TRUSTED_ORIGINS = ['https://django-cloudrun-yd43yjf7ya-uc.a.run.app'] SECURE_SSL_REDIRECT = True SECURE_PROXY_SSL_HEADER = ("HTTP_X_FORWARDED_PROTO", "https") else: ALLOWED_HOSTS = ["*"] I've also tried hardcoding the CLOUDRUN_SERVICE_URL to the url provided on deployment, https://django-cloudrun-yd43yjf7ya-uc.a.run.app but it didn't work. With and without the slash at the end. Also did a sanity check by writing a simple hello world view to check if my changes are really getting through. -

why the django custom middleware not able to catch the exception?

How to use Django's GeneratedField to keep count of related objects?
Let's say I have the following models: class Shop(models.Model): ... @property def products_count(self): return Product.objects.filter(shop=self).count() class Product(models.Model): shop = models.ForeignKey(Shop, on_delete=models.CASCADE) ... The products_count property is being used to get the number of products in a shop. With the release of Django 5 and generated fields, is there a way to use this to store the count instead? Or am I misunderstanding the use of generated fields? -

How to define factory with specific random choice for Django model?
i would like to define a factory class for a User django model like this : class User(models.Model): name = models.CharField(null=True, blank=True) created_date = models.DateField(null=True, blank=True) but for all fields, i would like to have a fake value from Faker or None because the model allow null. Ideally, the choice between fake value and None is made by probability for example 90% for fake value and 10% for none. i guess a factory like this class UserFactory(factory.django.DjangoModelFactory): name = factory.Faker("random_choice", elements=[factory.Faker("name"), None], p=[0.90, 0.10])) created_date = factory.Faker("random_choice", elements=[factory.Faker("date"), None], p=[0.90, 0.10])) -

Django login username label not being overwritten
I added email to be used as an alternative input for the default Django login form and wish to change the label to Username/Email but the common solution I find isn't working. I tried variations on the following and some other solutions with no change to the default Username label. Create a custom login form extending the normal one. class CustomLoginForm(AuthenticationForm): username = forms.CharField( label="Your Custom Label", widget=forms.TextInput(attrs={'autofocus': True}) ) Configure a view to use the custom form with the custom login template. # views.py from django.contrib.auth.views import LoginView from .forms import CustomAuthenticationForm class CustomLoginView(LoginView): authentication_form = CustomAuthenticationForm template_name = 'login.html' Configure the url. # urls.py from django.urls import path from .views import CustomLoginView urlpatterns = [ path('login/', CustomLoginView.as_view(), name='login'), # other URL patterns ] I'm using crispy forms if that matters so in my template I'm using {{ form|crispy }}. I simply want to change the label but am usually getting doubled up labels with common solutions if I include another {{ form.username|as_crispy_field }} in addition to a label tag. Can I remove the label from this latter implementation somehow as a potential solution? I also tried: class CustomAuthenticationForm(AuthenticationForm): def __init__(self, request=None, *args, **kwargs): super().__init__(request, *args, **kwargs) self.fields['username'].label = … -
Is it possible to deploy a Django application that has no frontend component (i.e. is just a backend API)?
Question I have an app that uses Next.js in the frontend and a Django backend. I was able to get the frontend deployed simply enough but I am not sure how to deploy the backend. There is quite a lot of magic happening when using the Vercel deploy so I am not sure how to debug this. According to the Vercel CLI the deploy has completed successfully (I just used the no-arg vercel tool directly from the Django project root directory). The deploy tool appears to have figured out the project was based on Django/python and installed the missing dependencies and such. But now what? When you run a Django server it listens on port 8000 by default. Does Vercel set up a reverse proxy that forwards :80 and :443 connections on to the right place? As far as I am aware, Django does not itself natively support SSL connections (but the default deploy sets up certs and uses it). I suppose this is managed somehow? The behavior I see is that the deployment appears to complete successfully but when I try to hit the domain name in a browser I just see the NOT_FOUND error page: 404: NOT_FOUND Code: …
