Django application visible in the home network only if run by root
I have a web app on Django that I'm running with the internal server to make it see on my home network. If I run with my user with python manage.py runserver 0.0.0.0:8080 I can see it work but only within my host. If I try to reach on another PC on the same network I have connection refused. If I run the same command but with root user, so using sudo su, everything works and I can reach the server from any PC on the network.

How to update an instance with fields of related model

Errors with Deploying a Django and React App to Railway
I'm struggling to deploy my django app to railway. The app continues to successfully deploy to Railway, however when visiting the URL of my railway app, I continue to get the error: TemplateDoesNotExist at /index.html. Since I'm using react with Django, I understand the process of serving the static files from react after they are built, and when running this project locally, everything has been working fine, the issue only started once I began to deploy to Railway. For reference, the folder where I've stored my reactapp is called 'reactapp'. Here are the key components of my manage.py file: ALLOWED_HOSTS = ["myprojecturl.railway.app", "127.0.0.1"] CORS_ALLOWED_ORIGINS = [ "http://127.0.0.1:8000/home/", "myprojecturl.railway.app" ] TEMPLATES = [ { 'BACKEND': 'django.template.backends.django.DjangoTemplates', 'DIRS': [ os.path.join(BASE_DIR, 'api/templates/api'), BASE_DIR / 'reactapp/build', ], 'APP_DIRS': True, 'OPTIONS': { 'context_processors': [ 'django.template.context_processors.debug', 'django.template.context_processors.request', 'django.contrib.auth.context_processors.auth', 'django.contrib.messages.context_processors.messages', ], }, }, ] STATIC_ROOT = os.path.join(BASE_DIR, 'staticfiles') STATIC_URL = 'static/' STATICFILES_DIRS = [ BASE_DIR / 'reactapp/build/static', ] My main urls.py file: path('', TemplateView.as_view(template_name='index.html')) I'm confused because this project works fully well locally, but the problems keep arising when deploying to Railway. Any help is appreciated, Thanks! -
how to get current user data from forms.py file in Django application?
Can't figure out how to get user data when getting form data. The idea is that the label and date-attribute('data-word-translate') should store the data obtained from the user's tables.

Disable perfomance measures for some transactions in Sentry
Our application written on stack Django\Postgres\Redis\Celery + Vue. As one of the monitoring tool we are using Sentry. Sentry measures performance for transactions. It's possible to control how many transaction will be covered by Sentry with set up sample rate. Also we can control which transaction could be covered with filtering them by (for example) path. How can i exclude transactions from performance monitoring (but still watch them for issues)? -
How to create *working* data migration using relation ot custom User in Django?
I've just started a new project and I'm using custom User model (from django-authtools). Everything works perfect until I got tired of constantly creating example data after wiping the db and decided to add a data migration for development purposes. Mind you, I specifically don't want to use fixtures for this. I have a ContactPerson model that references settings.AUTH_USER_MODEL and I'm using apps.get_model() calls in the migration. Everything by the books (or so it seems): # clients/models.py ... class Client(models.Model): name = models.CharField(max_length=128) class ContactPerson(models.Model): client = models.ForeignKey(Client, on_delete=models.CASCADE) user = models.ForeignKey( settings.AUTH_USER_MODEL, on_delete=models.CASCADE, related_name="as_contact_person", ) # migration from django.contrib.auth import get_user_model from django.db import migrations def create_example_data(apps, schema_editor): Client = apps.get_model("clients", "Client") ContactPerson = apps.get_model("clients", "ContactPerson") User = get_user_model() jim_user = User.objects.create_user( email="j.halpert@dundermifflin.com", password="*", name="Jim Halpert" ) dunder_mifflin = Client.objects.create( name="Dunder Mifflin, Inc.", ) ContactPerson.objects.create( client=dunder_mifflin, user=jim_user, ) class Migration(migrations.Migration): dependencies = [ ("clients", "0001_initial"), ] operations = [ migrations.RunPython(create_example_data) ] But trying to run the migration I get this error: ValueError: Cannot assign "<User: Jim Halpert j.halpert@dundermifflin.com>": "ContactPerson.user" must be a "User" instance.

Full path is not saved to media when I implement django-tenants in my django project
I am implementing multitenant in a django project with PostgreSQL for this I implemented a library called django-tenants but I have a small problem what I wanted was to save the media files for each scheme in a folder with the same name of the scheme for it in the official documentation It told me that I had to put this configuration in my settings.py.

Can't serve files located in static root with whitenoise
I am trying to serve my static files in my testing environment that's suppose to mirror my production environment that uses Whitenoise. In setting.py, I believe these are the relevant parts of the issue: DEBUG = True INSTALLED_APPS = [ 'whitenoise.runserver_nostatic', 'django.contrib.admin', # the rest of the apps ] STATICFILES_STORAGE = 'whitenoise.storage.CompressedManifestStaticFilesStorage' if not DEBUG: STATIC_ROOT = os.path.join(BASE_DIR, 'static') STATIC_URL = 'static/' else: STATIC_URL = 'static/' STATIC_ROOT = os.path.join(BASE_DIR, "static") # STATICFILES_DIRS = [ os.path.join(BASE_DIR, 'static')] WHITENOISE_USE_FINDERS = False I set WHITENOISE_USE_FINDERS = False to ensure that my development environment is serving files the way Whitenoise would. Regardless, none of the static assets are being served. The only time things seem to work is when I uncomment STATICFILES_DIRS and set STATIC_ROOT = 'static/, but I can't have that for my production environment. This problem has been troubling me for a long while now and if anyone can offer some insight, I'd appreciate it a lot. -

How to send emails in the same thread in Django?
I am wondering how can I send email in the same email thread using django.core.mail. I have an APIView that handles post requests from my contact form. It receives the contact form input and sends it to my email. In case when the email address from form input was already used (e.g. first form was submitted with mistakes), I would like such forms to be sent in the same email thread, rather than in separate emails. So basically every thread should contain submitted forms with the same email address as replies to the original email. views.py from rest_framework.views import APIView from rest_framework.response import Response from .serializers import ContactFormSerializer from rest_framework import status from django.conf import settings from django.core.mail import EmailMultiAlternatives from django.template.loader import render_to_string from django.utils.html import strip_tags class ContactFormAPIView(APIView): def post(self, request): serializer = ContactFormSerializer(data=request.data) if serializer.is_valid(): contact_form = serializer.save() subject = 'New Contact Form Submitted' context = { 'name': contact_form.name, 'email': contact_form.email, 'subject': contact_form.subject, 'message': contact_form.message, 'submitted_at': contact_form.submitted_at, } html_content = render_to_string('api/contact_form.html', context) text_content = strip_tags(html_content) email = EmailMultiAlternatives( subject, text_content, from_email=settings.EMAIL_HOST_USER, to=[settings.EMAIL_HOST_USER] ) email.attach_alternative(html_content, 'text/html') try: email.send() except Exception as e: return Response({'detail': f'Failed to submit the contact form: {str(e)}'}, status=status.HTTP_500_INTERNAL_SERVER_ERROR) return Response({'detail': 'Contact form submitted successfully.'}, … -
