Nuxt Auth 'loginWith' function doesn't send data to DRF
I recently tried to combine Nuxt.js with Django. Nuxt.js has a module called Nuxt Auth (I use @nuxtjs/auth-next), which is pretty straightforward and simple to use. However, I ran into a problem when I tried to get the post data when using $auth.loginWith(...) in a Django APIView. When I print out request.POST, it returns an empty QueryDict. When I log in with the standard DRF forms, I get my token as expected (I use JWT for authentication). I first thought that I did something wrong in my Nuxt.js frontend, so I cloned some repos on GitHub to see how they have done it (tickstudiu, ammezie). I then tried to combine their frontend with my backend. I also watched a tutorial on YouTube. Still the same problem... That's why I think that it is a Nuxt + Django specific problem because otherwise, the other repos would work, right? Or maybe I just do something wrong every time... This is what I get when I log in with standard DRF form: HTTP 200 OK Allow: POST, OPTIONS Content-Type: application/json Vary: Accept { "username": "admin", "token": "eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI1NiJ9.eyJ1c2VybmFtZSI6ImFkbWluIiwiZW1haWwiOiJhbmRyZWFzLmdlcmFzaW1vdzEyQGdtYWlsLmNvbSIsImV4cCI6MTYyMjc5NjQ2N30.XQ58Fo0nOS2C44SRQG5A2vEDT0fOXJTIrHG8XNaxzBo" } Here is my Login API in Django: class LoginAPIView(GenericAPIView): serializer_class = LoginSerializer def post(self, request, … -
How to pull secrets from Kubernetes into GitHub action to run Django migrations for AKS deployment?
I have taken up the challenge of automating the deployment of my company's Django-based application that is done with AKS but I am very new to it. My initial idea is to accomplish it by upgrading the steps in a GitHub workflow that acts on the release of a new version. I have structured it with three jobs. build, migrate and deploy: build: Simply build the Docker image and push it to the container registry on DockerHub - this step is successfully done. migrate: Run the migrations in the production database from python manage.py migrate - here lies the problem. deploy: Deploy the image to the Kubernetes cluster - successfully done. Step 2 is the problem because we store the Postgres database credentials inside the Kubernetes cluster and to run the migrations I need those secrets to pass them as environment variables before I call the migrate command. So I am stuck on how I can pull those secrets from Kubernetes and use them to run a command in a step in GitHub action like this: migrate: needs: build runs-on: ubuntu-latest steps: - uses: actions/checkout@v2 - name: Set up Python 3.8 uses: actions/setup-python@v2 with: python-version: 3.8 - name: psycopg2 prerequisites … -
Stripe "webhook" error with "custom user model" (Django)
I'm trying to configure Django Stripe Subscriptions. And now trying to setup webhook to create a new customer data by below code. views.py import stripe from django.conf import settings from django.contrib.auth.models import User from subscriptions.models import StripeCustomer ... # Get the user and create a new StripeCustomer user = User.objects.get(id=client_reference_id) StripeCustomer.objects.create( user=user, stripeCustomerId=stripe_customer_id, stripeSubscriptionId=stripe_subscription_id, ) print(user.username + ' just subscribed.') I'm getting error at user = User.objects.get(id=client_reference_id) because I'm using "custom user model". therefore I changed the above code to user = settings.AUTH_USER_MODEL.objects.get(id=client_reference_id) But still, it does not work. Is there any other way to write to get "user data"? I'm following this manual to create this app https://testdriven.io/blog/django-stripe-subscriptions/ Below is other codes. My models.py from django.conf import settings from django.db import models class StripeCustomer(models.Model): user = models.OneToOneField(to=settings.AUTH_USER_MODEL, on_delete=models.CASCADE) stripeCustomerId = models.CharField(max_length=255) stripeSubscriptionId = models.CharField(max_length=255) def __str__(self): return self.user.username accounts/models.py from django.contrib.auth.models import AbstractUser class CustomUser(AbstractUser): class Meta: verbose_name_plural = 'CustomUser' My settings.py #used for django-allauth AUTH_USER_MODEL = 'accounts.CustomUser' 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 should I implement email verification using restframework-simple-JWT?
I have been working on custom API token logic, that would allow me to verify users using just their email, but not username and password. How I see it: One user send me credentials (just an email address); Django SMTP server sends an email with verification code; User sends its email address and verification code to the server and then gets access and refresh tokens; I read approximately the same question, but I did not find the answer concrete enough, so I would be glad to hear any suggestion how to solve it. -

Django Admin now showing model list in iframe — what changed?
I have built a Django application with a custom interface. It hasn't been changed in a couple of years. These (previous) servers are running Django 3.0.8. Recently I set up a new server, and the Django Admin interface now shows the model list in a scrolling iframe, and long tables on the right side are also scrolled independently of the page. This server is running Django 3.2.3. I don't like the new interface, but it more importantly it will require an extensive rewrite of our custom admin css. Can anyone point me to information about the change, or tell me if there is a setting to disable it? -
