Dockerized Django-React-PostgreSQL App Not Serving Frontend Despite Successful Build and Container Rebuild
I have a Dockerized application setup that includes a React frontend and a Django backend service. Despite successfully building the Docker container and ensuring the backend is running as expected, when I attempt to access the frontend, I'm met with the following message: 'This URL is only accessible after you've built the React frontend.' I've attempted to rebuild the Docker container from scratch to ensure there are no caching issues, but the problem persists. Environment: Operating System: Win10 -- Using Ubuntu through WSL for building the container Docker Version: Docker version 25.0.3, build 4debf41 Node Version: 10.5.0 Steps Taken: Rebuilding the Docker Container: I used the command docker build --no-cache -t mycontainer:latest . to ensure a fresh build without using any cached layers. Running the Container: After rebuilding, I ran the container using docker run -d -p 8000:80 --name mycontainer mycontainer:latest. Verifying Backend Functionality: I can confirm the backend services are running as expected, responding to API calls. Dockerfile: # Stage 0: Build React Frontend FROM node:16 AS build-frontend WORKDIR /app/frontend COPY frontend/package\*.json ./ RUN npm install COPY frontend/ . RUN npm run build # Stage 1: Build Django Application FROM tiangolo/uwsgi-nginx:python3.9 # Set environment variables ENV PYTHONDONTWRITEBYTECODE=1 \ PYTHONUNBUFFERED=1 … -
Django Reuse Model Serializers Custom Validators
I have below serializer.py file. I have validate_semester() present in SubjectSerializer(), I want to reuse the same method in my StudentSerializer() class.

importing via Pandas CSV into Django model manytomanyfield

Issue with Django's LoginView after customizing User Model
I've encountered an issue after customizing Django's built-in User model (AbstractUser). I've created a custom user model named TheUser which inherits from AbstractUser.

Second celery task in chain executing before database updates from first task are completed
I have a a chain of celery tasks and the second task needs to run, not just after the first task is complete, but after the database updates from the first task are complete.

Using django signals to update status of multiple models
I'm currently working on a Django project where I have models for ClientOrders, DesignerJob, and PrinterJob. I want to implement a functionality where changes in the status of DesignerJob and PrinterJob models trigger updates to the status of the associated ClientOrders model. For example, when the status of a DesignerJob changes from "new" to "in_progress," I want the status of the corresponding ClientOrders model to be updated to a specific status. Similarly, when the status of a PrinterJob changes, I want the associated ClientOrders status to be adjusted accordingly. I'm planning to use Django signals to achieve this, but I want to make sure I follow best practices and avoid potential pitfalls.Here are my specific questions: Signal Handling Approach: Should I use one signal for each model and implement all the conditions in that signal or make separate signals for each case? Circular Signal Calling: If I have a case where say PrinterJob signal updates DesignerJob status, will it cause circular calling? But this case is very unlikely. class ClientOrders(models.Model): franchise = models.ForeignKey( Franchise, on_delete=models.CASCADE, null=True) order_id = models.CharField(max_length=100, default=0 , unique=True) order_type = models.CharField(max_length=50, default='shop') payment_method = models.CharField(max_length=50, default='cash') card_no = models.CharField(max_length=16, default='', blank=True) expiry = models.CharField(max_length=50, default='', blank=True) … -

How do I load a django template using absolute paths?
I have a template xyz.html stored in the path /doc-templates/ so the full path is /doc-templates/xyz.html I'm trying to load the template using my_template = get_template('/doc-templates/xyz.html') But this raises the TemplateDoesNotExist exception. Any ideas before I roll out my own template loader? PS: Yes I know where Django templates should be, I just want to see if this is possible now that everything is being "dockerized" I have explicitly enabled django.template.loaders.filesystem.Loader and set the DIRS to a non empty list as documented but it seems to be ignoring the absolute path (possibly appending it to the DIRS list) -

Issue with Google login using Django allauth: Not prompted to select Google account in Incognito mode or certain browsers (opera, Edge)
I'm using Django allauth for Google login in my web application. Everything works fine, but I've encountered an issue where when users try to log in using Google in Incognito mode or with certain browsers like Opera or Edge, they are not prompted to select a Google account. Instead, it automatically logs in with the previously logged-in Google account. Here's a snippet of my settings in settings.py: SITE_ID = 1 SOCIALACCOUNT_ADAPTER = 'microdistribution.users.adapters.CustomSocialAccountAdapter' ACCOUNT_USER_MODEL_USERNAME_FIELD = None ACCOUNT_EMAIL_REQUIRED = True ACCOUNT_USERNAME_REQUIRED = False ACCOUNT_AUTHENTICATION_METHOD = 'email' SOCIALACCOUNT_LOGIN_ON_GET=True ACCOUNT_LOGOUT_ON_GET = True SOCIALACCOUNT_EMAIL_AUTHENTICATION = True ACCOUNT_SESSION_REMEMBER = False SOCIALACCOUNT_PROVIDERS = { 'google': { 'AUTH_PARAMS': {'access_type': 'online'}, } } MIDDLEWARE = [ 'django.middleware.security.SecurityMiddleware', 'django.contrib.sessions.middleware.SessionMiddleware', 'django.middleware.common.CommonMiddleware', 'django.middleware.csrf.CsrfViewMiddleware', 'django.contrib.auth.middleware.AuthenticationMiddleware', 'allauth.account.middleware.AccountMiddleware', #new 'microdistribution.utils.middleware.DynamicSiteMiddleware', #new ] INSTALLED_APPS = [ 'django.contrib.sites', 'allauth', 'allauth.account', 'allauth.socialaccount', 'allauth.socialaccount.providers.google', ] Custom Adapter im using class CustomSocialAccountAdapter(DefaultSocialAccountAdapter): def save_user(self, request, sociallogin, form=None): user = sociallogin.user # Check if the user already exists existing_user = self.get_existing_user(user) if existing_user: return existing_user # If the user doesn't exist, create a new one try: new_user = super().save_user(request, sociallogin, form) new_user.name = sociallogin.account.extra_data.get('name') new_user.client_uid_id = User.objects.get(id = settings.CLIENT[request.META['HTTP_HOST']].client_uid_id) new_user.save() return new_user except Exception as e: print(f"Error While Creating User: {e}") return None def get_existing_user(self, user): existing_user = None try: … -
React & Django - WARNING:django.request:Forbidden: /api/user - SessionAuthentication
I'ved created this Django & React project (https://github.com/axilaris/docker-django-react-celery-redis), and I'm having difficulties with accessing API with SessionAuthentication. You can easily spin off with: docker-compose build docker-compose up I keep getting access issue with accessing /api/user (you can test with register, login) backend_container | Forbidden: /api/user backend_container | WARNING:django.request:Forbidden: /api/user You can look more the logs here: https://gist.github.com/axilaris/7b7a5c50f4f7112b440eaf8ef8100d9d In my django api code (backend/user_api/views.py): class UserView(APIView): permission_classes = (permissions.IsAuthenticated,) authentication_classes = (SessionAuthentication,) def get(self, request): serializer = UserSerializer(request.user) return Response({'user': serializer.data}, status=status.HTTP_200_OK) In settings.py: CORS_ALLOWED_ORIGINS = [ 'http://localhost', 'http://127.0.0.1', 'http://0.0.0.0', ] CORS_ALLOW_CREDENTIALS = True INSTALLED_APPS = [ ..

I feel the CORS are setup correctly and credentials are set true on both backend and frontend. -
