Is it possible to save 2 or more related models in one view? in Django?
I don’t know how to save multiple linked models in django, I’m trying to override get_success_url but I’m at a dead end(. I'm trying to make sure that when saving a form, a model with basic information is saved, associated with the model with a phone number, and that is associated with the client's name. This is all so that you can save several numbers for one client; in the future, I also want to connect the client with the client’s address, because there can be several addresses. Here's the code: views.py from .models import Orders, Person, Phone from django.views.generic import ListView, DetailView, CreateView, UpdateView, DeleteView from .forms import OrdersForms, AuthUserForm, RegisterUserForm from django.urls import reverse, reverse_lazy from django.contrib import messages from django.contrib.auth.views import LoginView, LogoutView from django.contrib.auth.models import User from django.contrib.auth import authenticate, login from django.contrib.auth.mixins import LoginRequiredMixin from django.http import HttpResponseRedirect class OrderCreateView(CustomSuccessMessageMixin, CreateView): model = Orders template_name = 'create.html' form_class = OrdersForms success_url = reverse_lazy('data_base') success_msg = 'Заявка дабавлена' def form_valid(self, form): self.object = form.save(commit=False) self.object.author = self.request.user self.object.save() return super().form_valid(form) def get_success_url(self): # phone_number = self.request.POST.get('phones') name = self.request.POST.get('client_name') phone_number = self.request.POST.get('phones') id = self.request.POST.get('id') # ??

IntegrityError NOT caught during Unit Test but other DB errors are caught
I'm using Python 3.7 and Django 3.0.3 I have a unit test that looks like this: class MaintenenceEndpointTest(APITestCase): """Maintenence Endpoint tests """ def test_reset_cost_center_throws_error_if_sales_profile_is_not_in_database(self): """Ensure the database throws an error and the endpoint returns 500 if the sales_profile is not in database""" response = self.client.post('/maintenance/reset_cost_center/', data={"cost_center_code": "test_cost_center_code", "sales_profile": "Fronter SMIA NOT PRESENT"}, format='json', HTTP_ACCEPT='application/json') self.assertEqual(response.status_code, status.HTTP_500_INTERNAL_SERVER_ERROR) and inside the Django endpoint code that gets called by the test, I have this: try: # Call the Database with an Update using the field(s) chosen by the caller (in kwargs now) CostCenter.objects.filter(cost_center_code=cost_center_code).update(**kwargs) except Exception as e: logging.error( f' CostCenterUpdateProfileAndRole:post failed with errors.

Problems configuring my Django project to upload static and media files to DigitalOcean Spaces
I have created a social media app using Django and Vue. My frontend is hosted on Vercel (which is working just fine) and my backend is hosted on DigitalOcean's App Platform (I am NOT using a droplet) and connected to my Github repo. Everything about my app is functioning perfectly well except for my user-uploaded media files. I am using django-storages (S3Boto3Storage) for this purpose and have followed all of the instructions in several tutorials (such as this one, this one, and the documentation). I have even gotten my static files up on DigitalOcean Spaces using this process (as in, when I check my bucket, the correct files appear to be there), but every time I try to deploy, it fails at python manage.py collectstatic. I've tried changing literally every single element of my settings.py file pertaining to static and media variables, creating a new Spaces bucket, messing with STATICFILES_DIRS and STATIC_ROOT, and updating/changing my App-level environment variables in the DigitalOcean App Platform UI. However, I keep getting a few different errors that I've been having trouble debugging. Sometimes I get this error: ?: (staticfiles.W004) The directory '/workspace/backend/static' in the STATICFILES_DIRS setting And other times I get this error: botocore.exceptions.ClientError: … -
Websocket message from Django backend to javascript frontend

The consumers.py and routing.py are in the same app where I want to use the ws = create_connection("ws://127.0.0.1:8080/notifications") My issue is that, if I set a message from the backend with ws = create_connection("ws://127.0.0.1:8080/notifications") ws.send(json.dumps({"message": "Ricevuto"})) ws.close() The frontend which is correctly connected to the same websocket with var socket = new WebSocket("ws://127.0.0.1:8080/notifications") // Creating a new Web Socket Connection // Socket On receive message Functionality socket.onmessage = function(e){ console.log('message', e) console.log(e.data) // Access the notification data } // Socket Connet Functionality socket.onopen = function(e){ console.log('open', e) } seems to no receive the message even if the consumer on DJango correctly receive it consumer.py import json from channels.generic.websocket import WebsocketConsumer class ChatConsumer(WebsocketConsumer): def connect(self): self.accept() self.send(text_data=json.dumps({"message": "Benvenuto"})) def disconnect(self, close_code): pass def receive(self, text_data): print(text_data) text_data_json = json.loads(text_data) message = text_data_json["message"] self.send(text_data=json.dumps({"message": message})) routing.py from django.urls import re_path from . import consumers websocket_urlpatterns = [ re_path(r"notifications", consumers.ChatConsumer.as_asgi()), ] asgi.py application = ProtocolTypeRouter( { "http": django_asgi_app, "websocket": AllowedHostsOriginValidator( AuthMiddlewareStack(URLRouter(websocket_urlpatterns)) ), } ) -

Django ORM group by on primary key mysql
In the django ORM it's easy to group by when using an aggregate function like this: from django.contrib.auth.models import User User.objects.values('id').annotate(Count('id')) However if I want to group by without an aggregation function (in case of a join for example) User.objects.filter(groups__name='foo') You can use distinct function, but it will distinct on all columns. Which is painfully slow. In some other DB you can do DISTINCT ON but not on mariadb/mysql. Is there a way to group by a specific column with the django ORM or do I have to write RawSQL ? -

Life Cycle of Daemon thread and Non Daemon Thread in Django

I have a Django website in production so DEBUG = False There is a setting: SESSION_COOKIE_SECURE = True If it is set to True then I can access the admin and log in, but then I cannot access the website itself and I get a bad gateway error. If the setting is missing or set to False then I can access the website fine but I cannot log into admin. A bit confusing Here are the settings related to domains and CSRF: ALLOWED_HOSTS = ["localhost","102.219.85.91","founderslooking.com","app.founderslooking.com"] CORS_ALLOWED_ORIGINS = [ "http://localhost", "http://127.0.0.1", "http://localhost:file", "http://app.founderslooking.com", ] CORS_ORIGIN_ALLOW_ALL = True CORS_ALLOW_CREDENTIALS = True SESSION_COOKIE_SAMESITE = None SESSION_COOKIE_DOMAIN = "founderslooking.com" SESSION_COOKIE_SECURE = True CSRF_TRUSTED_ORIGINS = ["http://localhost", "http://*.127.0.0.1", "http://app.founderslooking.com",] INTERNAL_IPS = [ "127.0.0.1", ] First time I deploy a Django site so not sure what the settings should be for production.

Confused about details of oauth2 authorization and authentication after reading Django-salesforce documentation
I am trying to integrate Salesforce with a Django application, so users can login into my site and push data themselves into the salesforce database. I have read the django-salesforce github page, and I confirmed that I can make postman calls to the database with oauth2 tokens, but I have some questions which probably stems from my ignorance of this subject. If I hardcode my username and password-concat-token into the django salesforce database settings, then won't all new database entries be authorized under my account? Ideally, shouldn't users authenticate into my application with their salesforce account, and then make API calls under the authorization of their own account? Or does this not matter at all? Also, if I hardcode my username and password-concat-token like above, then do I need a separate authentication and authorization system? If I hardcode my token into the django database information like that, then theoretically any backend call would inject my account's oauth2 information to make API calls. I was hoping users could click on a "Sign in with Salesforce" button and be authenticated on my site that way, going 100% for the social login system and not make my own. Any clarifications on my misunderstandings … -
Is there a way to pass django value to python script?
The python script that I have written fetches ticker data and historical data for the stock. Currently the stock value is hardcoded as you can see below. if __name__ == "__main__": stock = 'TSLA' data = GetData() data.tickerData(stock = stock) data.getHistData(stock = stock, startDate = startDate, endDate = endDate) I would like to know whether it's possible to send the user inputted value [via django forms] to this main function and have this script executed. If someone has come across this scenario, please advise. -

Django not loading static from nginx in docker container
I django server cannot load static files, however they are accessible directly through a URL. I have a django server that is served by gunicorn inside a docker container. My Django static sttings.py: STATICFILES_DIRS = [ (os.path.join(BASE_DIR, "static")), ] STATIC_URL = "/static/" STATIC_ROOT = os.path.abspath(os.path.join(BASE_DIR, "../static")) My Nginx conf: http { sendfile on; server { listen 80; server_name localhost; location / { proxy_pass http://gunicorn:8000; } location /static/ { autoindex on; alias /static/; } } } My nginx docker-compose configuration: nginx: image: nginx:1.19.6-alpine depends_on: - gunicorn ports: - "80:80" expose: - "80" - "443" volumes: - ./nginx.conf:/etc/nginx/nginx.conf - ./certs:/etc/nginx/certs - nginx_static:/static When i start the django server with debug mode on, the files load at localhost:8000 where the gunicorn container is, but they are not avaliable at localhost:80 where my nginx container is. When I start it with debug off, static files arent loaded at all. When I try to access a static file through nginx, e.g. localhost:80/static/my_static.css the file loads I think this may be an issue with my django settings as calling the static in a html template like: {% static 'img/logo.png' %} will load that image, however none of my other css files will load even though {% …
