How to connect 2 views in the same Django app? (ListView and EditView)
I have 2 apps called Prospecto(which means Prospect) and Cliente(which means Customer). When you see a register in EditView and click on its checkbox, you can indicate whether the register is still in Prospecto or Cliente If you don't click on the checkbox, that record is still in the Propsecto If you click the checkbox, that record becomes a Cliente and is no longer a Prospect In the code I did, when I clicked the checkbox, it turns into record in Customer(that's ok), but I can't delete it from Prospecto(in ProspectoListView). **views.py class ProspectoListView(ListView): model = Prospecto template_name = 'prospectos.html' context_object_name = 'prospectos' def get_queryset(self): queryset = super().get_queryset() fecha_inicio = self.request.GET.get('fecha_inicio') fecha_fin = self.request.GET.get('fecha_fin') if fecha_inicio and fecha_fin: queryset = queryset.filter(fecha__range=[fecha_inicio, fecha_fin]) elif fecha_inicio: queryset = queryset.filter(fecha__gte=fecha_inicio) elif fecha_fin: queryset = queryset.filter(fecha__lte=fecha_fin) return queryset def ProspectoEditar(request, pk): prospecto = get_object_or_404(Prospecto, pk=pk) if request.method == 'POST': form = ProspectoForm(request.POST, instance=prospecto) if 'es_cliente' in request.POST: cliente = Cliente(nombre=prospecto.nombre) cliente.save() prospecto.es_cliente = True prospecto.delete() if form.is_valid(): form.save() return redirect('prospectos:prospectos_list') else: form = ProspectoForm(instance=prospecto) return render(request, 'prospectos-editar.html', {'form': form}) I try with this solution, adding delete() but it doesn't work class ProspectoListView(ListView): model = Prospecto template_name = 'prospectos.html' context_object_name = 'prospectos' def get_queryset(self): fecha_inicio … -

Docker Compose Up - Received Permission Denied
I am unable to start a new django/python app with docker. I received permission denied. I recently bought a new computer and my app I had previously used with docker is working fine. I then recently tried to build a flask/carmen app but deleted everything that I had loaded. Im not sure if that is effecting my docker containers but my previous app will still do docker compose up and down. I tried this weekly-finances docker-compose config name: weekly-finances services: web: build: context: /Users/eleahburman/Desktop/code/weekly-finances dockerfile: Dockerfile command: - python - manage.py - runserver - 0.0.0.0:3000 networks: default: null ports: - mode: ingress target: 3000 published: "3000" protocol: tcp volumes: - type: bind source: /Users/eleahburman/Desktop/code/weekly-finances target: /code bind: create_host_path: true networks: default: name: weekly-finances_default and the docker compose seems correct.

I have no clue what's going on
I just got to finishing a tutorial with the following link: https://www.youtube.com/watch?v=eOVLhM6_6t0&t=572s and the last step is to check that the server is running properly using python manage.py runserver however when I try to do this, the usual error pops up: [Errno 2] No such file or directory which I was able to solve with the absoulte path solutions provided online. However my problem is not that the problem comes when I finally reach the right cd to be in and all of this errors appear in the terminal: https://docs.google.com/document/d/1PJB2rRQ-Lyd8GQd3Hl9krkTlHD9C60WeakNk-9tM5y0/edit It was so long I couldn't even copy it all here without the computer bugging I have no clue what even is going on here or how could I solve it. I've been stuck here for the past hour. Thanks for the help. -
404 Not Found nginx/1.18.0 (Ubuntu) on running django rest framework with EC2 along with gunicorn, nginx and Supervisor
So I hosted my django rest framework project on AWS EC2. I integrated nginx, gunicorn and Supervisor along with it. After it shows successful configuration, the only link that works is the default one. Example http://35.154.109.114/ works but any other URL say http://35.154.109.114/test isn't working How ever these links work when I use a standard gunicorn --bind 0.0.0.0:8000 DemoProject.wsgi:application command. Please let me know how to work this out. -

Link from Django Model's "absolute url" to its admin page
According to the docs, you can specify a get_absolute_url in your Django Model for a "View on site" button to show up on Django Admin. However, how would you do the opposite? A link on the above defined "absolute url" that takes you to the admin page for that instance? I can think of ways to hardcode the admin url and fill in just the instance ID, but I was hoping for a pythonic way (e.g. instance.get_admin_url()) Thanks for the help! -
I am Trying to create my first Django Project on VS Code and I cant figure out how properly install the packages needed
I am a begginer programmer who was trying to create his first project in VS Code. I installed in the Windows Powershell Django and activated a virtual environment as followed through the following pages: https://docs.djangoproject.com/en/4.2/howto/windows/ And also tried to install it on VS Code directly following this tutorial on YT: https://www.youtube.com/watch?v=Wfu5dPbiyKA however the following problems occur when I check the files in VS Code wsgi.py: from django.core.wsgi import get_wsgi_application This line throws the following warning: Import "django.core.wsgi" could not be resolved from source and the same error is thrown in the urls.py file and asgi.py file for the following: Asgi: from django.core.asgi import get_asgi_application Urls: from django.contrib import admin from django.urls import path After some research I discovered that either I installed incorrectly Django into my computer or VS Code or either I can install them individually, however neither have worked as when I try to check the status of django it says that the module doesnt exist. Please help, thanks -
Celery does not find models when performing the task
I'm writing an Api for a telephone newsletter, my code accepts dispatch requests and when it's time to start the newsletter it sends a request to an external Api, which in turn sends the messages themselves. If you run everything outside of docker, it works fine, but when you run it in docker-compose, the src.newsletter.models.Dispatch.DoesNotExist: Dispatch matching query does not exist. I'm pretty sure models with this index exist, but celery gives the error tasks.py from celery import shared_task from src.newsletter.models import Dispatch, Client, Message from config.settings.development import API_SENDING_URL, API_JWT_TOKEN import requests @shared_task def send_message_to_client(dispatch_id, client_id): dispatch = Dispatch.objects.get(id=dispatch_id) client = Client.objects.get(id=client_id) url = f"{API_SENDING_URL}{client.id}" headers = {"Authorization": f"{API_JWT_TOKEN}"} data = { "id": client.id, "phone": client.phone_number, "text": dispatch.text_message, } try: response = requests.post(url, headers=headers, json=data) print(response.status_code) if response.status_code == 200: message = Message.objects.create( status='S', dispatch=dispatch, client=client ) elif response.status_code == 401: message = Message.objects.create( status='F', dispatch=dispatch, client=client ) elif response.status_code == 400 or response.elapsed.total_seconds() > 10: # Повторная попытка отправки try: response_retry = requests.post(url, headers=headers, json=data) if response_retry.status_code == 200: message = Message.objects.create( status='S', dispatch=dispatch, client=client ) else: message = Message.objects.create( status='F', dispatch=dispatch, client=client ) except requests.exceptions.RequestException: message = Message.objects.create( status='F', dispatch=dispatch, client=client ) else: message = Message.objects.create( status='F', dispatch=dispatch, … -
Django Redirecting to custom prefilled form
So I have the following issue regarding a custom project. I made a page with different pets which are ready for adoption. Each one has a button for Details. I want when a user is Logged In to see a button which indicates that saying "Adopt". When the button is pressed I want to redirect him to a new page with some prefilled fields from the Pet model (the pet which is ready for adoption) and I want the user to fill few new fields. When he press another button (Send...etc.) to tell him that the request is send out. I tried and see that the pk of the first ready for adoption animal is 1, but when I go the url it is saying that no URL is found.

https forced in development by django. Problem with DJANGO_SECURE_HSTS_SECONDS?
Something in my Django code is forcing development server (runserver) redirection from http to https.

Django: aggregate django fields to avoid N + 1 problem
I have 3 tables/classes that are relevant to each other: CourseStudent - represents Student signed up to the course Presence - represents the attendance list of the CourseStudent CourseStudentPayment - represents the payments list for CourseStudent In the code it looks like this: class CourseStudentPayment(models.Model): course_student = models.ForeignKey( "CourseStudent", on_delete=models.CASCADE, related_name="course_student_payments", ) start_date = models.DateField(db_index=True) # other fields: price, currency, etc price = models.DecimalField(default=0, max_digits=10, decimal_places=2) def lessons_complete(self) -> int: return ( Presence.objects.filter( course_student=self.course_student, ) .filter(date__gte=self.start_date) .count() ) class Presence(models.Model): course_student = models.ForeignKey("CourseStudent", on_delete=models.CASCADE) date = models.DateField() # some other fields class CourseStudent(models.Model): # some course-related information student = models.CharField(...) def last_payment(self) -> CourseStudentPayment: return CourseStudentPayment.objects.filter(course_student=self).order_by("-start_date").first() So lessons_complete function calculates the number of the attendances since the payment date. Both CourseStudentPayment and Presence objects have CourseStudent pk. I want to render a list of payments for the students with lessons_complete in an efficient way. The dumb solution would be: get list of payments. course_payments = CourseStudentPayment.objects.all() for each payment I call lessons_complete. This solution creates N+1 problem, where for each payment I do Presence lookup. In SQL I would just join two tables (pseudocode): SELECT csp.*, count(p.id) from CourseStudentPayment csp JOIN Presence p ON scp.course_student_id = p.course_student_id WHERE p.date > … -
Why it can't pass a validation with the django form when set data after initializing
Why it can't pass a validation when I set data like this (form.data=request.POST) @login_required def add_delivery_view(request): user = request.user delivery = (Delivery.objects.filter(user=user) or [None])[0] form = AddDeliveryForm(instance=delivery) if request.method == 'POST': form.data = request.POST if form.is_valid(): delivery = form.save(commit=False) delivery.user = request.user form.save() return redirect('/') return render(request, 'order/add_delivery.html', {'form':form}) But when I set data like this, it works just fine ... if request.method == 'POST': form = AddDeliveryForm(data=request.POST, instance=delivery) if form.is_valid(): delivery = form.save(commit=False) ... I guess it something with initialization of form. Maybe I should add some method after form.data=request.POST Question is: What is the difference underneath the hood? Thanks in advance -
response.set_cookie() vs response.cookies[] in Django
I could set the cookies with response.set_cookie() and response.cookies[] as shown below: # "my_app1/views.py" from django.http import HttpResponse def test(request): response = HttpResponse('Test') response.set_cookie('first_name', 'John') # Here response.cookies['last_name'] = 'Smith' # Here return response Then, I could only delete response.set_cookie()'s cookie first_name rather than response.cookies[]'s cookie last_name with response.delete_cookie() as shown below: # "my_app1/views.py" from django.http import HttpResponse def test(request): response = HttpResponse('Test') response.delete_cookie('first_name') # Deleted response.delete_cookie('last_name') # Undeleted return response So, what is the difference between response.set_cookie() and response.cookies[] in Django? -
Django - Model - Is it possible to use dict key value in UniqueConstraint combined with other attributes
Short version of the question: Is it possible to use dict key value in UniqueConstraint. If not, advice on implementing the logic described; *I use postgreSql In django, I have a model which; has a name attribute which is an I18nCharField meaning, on the form, for the name attribute there are two inputs, one for english and one for portuguese. Other attributes are like below. Unique Constraints: (second one is the problem here) Acronym and Code can be null. This is why I have these UniqueConstraints with query in here. But the involvement of the name should be based on only the portuguese version. English one can be even blank. (name is mandatory but only the portuguese one) What my problem is; this name field is being saved as: {"en": "record5-level3", "pt": "registro5-nível3"} meaning, I cannot use this in the Unique Constraints as it is because someone can just use the same portuguese name and put random stuff in the english input. I cannot keep uniqueness on the pt name with other attributes. What I want to do is; customize this unique constraints in order to consider name as its pt value inside, or use the UniqueConstraints with name.pt Is … -
Simple audio player with <audio> tag not able to control time progress in chrome running on python server (but works on safari and node server)
Very basic audio player, running on python server locally. If I run it on safari, it works fine. If I run it on a node server, it works fine on chrome and safari. But ultimately this will be apart of a django project and needs to run on python server.

Lookup JSONField from DB without loading it as an object
I have a JSONField in one of my django models. I now want to write a very fast view function that is just meant to return that field as application/json content.

Django Multitenant - Populate connection list using default database
I have a Django Project with multitenant. Each client has is own database. I want to create a table in the default database containing the client. Something like this: class Tenant(models.Model): name = model.CharField(max_length=20) I want to use this model so that I can populate DATABASES setting or django connections and to avoid writing more code. How can I do it? -
Retrieve function for viewset without model
I am using object without RDS entry. Model class MyDummy(object): def __init__(self, **kwargs): for field in ('id', 'detail'): setattr(self, field, kwargs.get(field, None)) mydummys = { 1: MyDummy(id=1, detail={"test":"test"}), 2: MyDummy(id=2,detail={"test2":"test2"}) } Serializer class MyDummySerializer(serializers.Serializer): id = serializers.IntegerField(read_only=True) detail = serializers.JSONField(allow_null=True) def create(self, validated_data): return MyDummy(id=None, **validated_data) def update(self, instance, validated_data): for field, value in validated_data.items(): setattr(instance, field, value) return instance list function works well for now class MyDummyViewSet(viewsets.ViewSet): serializer_class = s.MyDummySerializer def list(self, request): serializer = s.MyDummySerializer( instance=m.mydummys.values(), many=True) return Response(serializer.data) However now I want to make retreive for url like api/mydummy/1 class MyDummyViewSet(viewsets.ViewSet): serializer_class = s.MyDummySerializer def list(self, request): serializer = s.MyDummySerializer( instance=m.mydummys.values(), many=True) return Response(serializer.data) def retrieve(self, request, pk=None): serializer = s.MyDummySerializer( instance=m.mydummys.values(), many=False) return Response(serializer.data) It returns, { "detail": null } I think I should narrowing by id in retrieve. How can I make it ?
