How to detect client disconnects on StreamingHttpResponse (Server Side Events) using Django/Django-Ninja?
We want to add Server Side Events in our application, but currently the while True loop runs indefinitely and client disconnect is not causing the task to stop. Reproducible example: @api.get("/events") async def get_events(request: ASGIRequest) -> StreamingHttpResponse: async def generate_message() -> AsyncGenerator[str, None]: while True: await asyncio.sleep(1) yield 'data: {"test": "testvalue"}\n\n' print("Working...") return StreamingHttpResponse( generate_message(), content_type="text/event-stream", headers={ "X-Accel-Buffering": "no", "Cache-Control": "no-cache", "Connection": "keep-alive", }, ) Above example will print Working... until server is closed (even if client closes connection and is not receiving the data). Any way to detect client disconnect to stop the while True loop? Already tried to return simple HttpResponse, putting code in try..except, creating def close, async def close methods on StreamingHttpResponse. django-ninja==0.22.2 django==4.2.13 uvicorn[standard]==0.29.0 -
How do I generate a PDF using pyppeteer in Django? Got error signal only works in main thread of the main interpreter

How to use LangChain to generate AI-based quiz questions in a specific JSON format in a Django application? [closed]
I'm new to LangChain and I'm working on creating a Django quiz generator app that uses AI to generate quiz questions. I want the generated questions to be in a specific JSON format as shown below: [ { "id": 1, "question": "What common aspect do physics and chemistry share?", "choices": { "a": "Laws of motion", "b": "Laws governing matter and energy", "c": "Laws of thermodynamics", "d": "Laws of electromagnetism" }, "answer": "b", "explanation": "Physics and chemistry share fundamental laws governing matter and energy, making it the correct choice." }, { "id": 2, "question": "What common aspect do physics and chemistry share?", "choices": { "a": "Laws of motion", "b": "Laws governing matter and energy", "c": "Laws of thermodynamics", "d": "Laws of electromagnetism" }, "answer": "b", "explanation": "Physics and chemistry share fundamental laws governing matter and energy, making it the correct choice." } ] Requirements: Input Parameters: The input to the model will have three parameters along with the text that the questions need to be generated from and I want it to return a response based on that. Output Format: The output should strictly be in the JSON format without any additional conversational text (e.g., no "Here are the questions you … -
Domain resolution fails for python requests-package in multithreading scenario
I am having a microservice hosted as an Azure Web App that sends outbound HTTP-POST calls based on various events. The calls have the characteristics of "fire-and-forget". Thus, I start a thread for each performed HTTP-request as follows: t = threading.Thread(target=self.perform_call, args=(target_url, notification_dto), daemon=True) t.name = f'notification_sending_{notification_dto.id}' t.start() The request itself is executed via the requests-package as follows (without any explicit session-management etc.): response = requests.post(target_url, timeout=5, headers=headers_dict, data=data_str) Sporadically, I see the following error in my log-file: Traceback (most recent call last): File "/agents/python/urllib3/connection.py", line 203, in _new_conn sock = connection.create_connection( ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/agents/python/urllib3/util/connection.py", line 60, in create_connection for res in socket.getaddrinfo(host, port, family, socket.SOCK_STREAM): ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ File "/opt/python/3.11.8/lib/python3.11/socket.py", line 962, in getaddrinfo for res in _socket.getaddrinfo(host, port, family, type, proto, flags): ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ socket.gaierror: [Errno -2] Name or service not known The above exception was the direct cause of the following exception: Traceback (most recent call last): File "/agents/python/urllib3/connectionpool.py", line 790, in urlopen response = self._make_request( ^^^^^^^^^^^^^^^^^^^ File "/agents/python/urllib3/connectionpool.py", line 491, in _make_request raise new_e File "/agents/python/urllib3/connectionpool.py", line 467, in _make_request self._validate_conn(conn) File "/agents/python/urllib3/connectionpool.py", line 1096, in _validate_conn conn.connect() File "/agents/python/urllib3/connection.py", line 611, in connect self.sock = sock = self._new_conn() ^^^^^^^^^^^^^^^^ File "/agents/python/urllib3/connection.py", line 210, in _new_conn raise NameResolutionError(self.host, self, … -
Docker build . hangs indefinitely without feedback on MacOS Big Sur
I'm new to Docker, and following along a course. I went step by step creating some basic files to start a Django project on Docker, which are the following: My DockFile is this one: FROM python:3.9-alpine3.13 LABEL maintainer="user" ENV PYTHONUNBUFFERED 1 COPY ./requirements.txt /tmp/requirements.txt COPY ./app /app WORKDIR /app EXPOSE 8000 RUN python -n venv /py && \ /py/bin/pip install --upgrade pip && \ /py/bin/pip install -r /tmp/requirements.txt && \ rm -rf /tmp && \ adduser \ --disabled-password \ --no-create-home \ django-user ENV PATH="/py/bin:$PATH" USER django-user Then, my .dockerignore file is this: # Git .git .gitignore # Docker .docker #Python app/__pycache__/ app/*/__pycache__/ app/*/*/__pycache__/ app/*/*/*/__pycache__/ .env/ .venv/ venv/ Finally, the requirements reads: Django>=3.2.4,<3.3 djangorestframework>=3.12.4,<3.13 After that I'm supposed to run docker build ., but when I do it hangs and does nothing. I had to shut it down a couple of times. Any idea of what I am doing wrong or at least have some feedback? -

My Django project is opening very slowly on the server
Please check out my site: pyterminator.com The site opens very late. I don't know what the reason is. I used dj-static package in wsgi file.

Django authentication testing failure: Authentication credentials were not provided
I am working on the user logic of my Django project.

Changing just the name of the django settings file causes error
I ran into a problem trying originally to use cookiecutter-django when using the docker compose production.yml vs the local.yml files Managed to shrink it down to this: https://github.com/xmclej/django-testing-01 The code is currently defaulted to use "config.settings.base" See the README.md file for the very minimal setup and instructions The problem is that when I change only the DJANGO_SETTINGS_MODULE value from "config.settings.base" to "config.settings.trial". Noting that the two files are identical inside. Get error.. ModuleNotFoundError: No module named 'config.settings.trial' Any thoughts?

Is there a way to restrict users to only see children of a parent element they belong to in Django Rest?
I have built a Django REST app for a client that allows users to join communities. The Community model has 20+ models that link back to it in some way (things like events, event dates, meetings, messages etc). I need a way to restrict users to only being able to perform CRUD operations on elements belonging to communities they are a part of. For example if user "John Smith" is a member of the "Animal Rescue Volunteers" community, he should only be able to read messages for that community and should not be able to create/edit messages in other communities. I have seen people use the get_queryset method of a ViewSet to restrict RUD processes like so: class MessageView(viewsets.ModelViewSet): queryset = Message.objects.all() serializer_class = MessageSerializer def get_queryset(self): return self.queryset.filter(message__community__in=self.request.user.communities) However this doesn't solve the problem with Creates and needs to be applied to each ViewSet to work. Is there a better way to do this? -
Only able to upload PNG images with django-ckeditor-5
I am building a simple blog application in Django and istalled django-ckeditor-5. I am able to upload PNG images with no problem, but when I try to upload JPG image of any size (or any other format), the browser throws an alert localhost:8000 says Couldn't upload file: filename.jpg I didn't include any restrictions in the models or in the settings. I basically copied the ckeditor configurations from their documentation. I didn't have this problem with the previous version of ckeditor, but apparently it has some vulnerability issues... Any ideas how I can enable other file formats for images? -

Django cannot find page with multiple similar URL paths
I am trying to create a Django site with different views/models spanning from the same level of the URL structure. Here is the URL structure I am trying to create: HOME PAGE -- Country --- State ---- City --- Topic ---- Article I am using the following code in urls.py: urlpatterns = [ path( "<slug:country_slug>/<slug:state_slug>/<slug:city_slug>/", CityIndex.as_view(), name="city_index", ), path( "<slug:country_slug>/<slug:topic_slug>/<slug:article_slug>/", ArticleDetail.as_view(), name="article_detail", ), path( "", HomeIndex.as_view(), name="home", ), The City Index path works fine. The issue I have is trying to access an article. Django only seems to attempt to match the first URL path. I enter a URL: "example-country/example-topic/example-article" Django returns the following error message: Page not found (404) No Destination matches the given query. Request Method: GET Request URL: http://127.0.0.1:8000/example-country/example-topic/example-article/ Raised by: content.views.destinations.CityIndex It seems that, because the pattern is similar to the URL pattern for "city_index", it attempts to match this, then return a 404 error. It doesn't move on to check the next URL pattern for "article_detail", which would then match an article and return a template. I tried switching the "article_detail" URL path to come first, above "city_index". This causes "article_detail" to return a template correctly, but now "city_index" does not. Effectively, Django will match … -

How i can implement this with the Button Click handler in DJANGO? <div class="card-body"> <img src="{{object.car_image.url}}" class="card-img-top" alt="..."> <div class="card-body"> <h5 class="card-title fw-bold text-uppercase gap-2"> {{object.car_name}} </h5> <p class="card-text btn btn-sm btn-light disabled">Brand : {{object.car_brand}}</p> <div class="d-flex gap-2"> <p class="btn btn-sm btn-primary disabled">Quantity :{{object.quantity}}</p> <p class="btn btn-sm btn-warning disabled ">Price :{{object.price}}</p> </div> <p class="card-text">{{object.description }}</p> {% if user.is_authenticated %} <button class='btn btn-sm btn-success'>Buy Car</button> {% endif %} </div> -

Lock file "postmaster.pid" contains wrong PID
I started my app with docker-compose.yml. Everything starts fine and works, but after a few minutes container database stops with lock file "postmaster.pid" contains wrong PID: 7834 instead of 1. I tried to delete postmaster.pid inside docker and containers, but this didn't help. I also did this procedure: How do I fix stale postmaster.pid file on Postgres?. But the problem persists. I don't understand what to do.

Django Update on UniqueConstraint
I'm trying to work with UniqueConstraint but I've been facing some issues trying to update it the way I want. I have the following model class QueryModel(models.Model): id = models.AutoField(_("query id"), primary_key=True) user = models.ForeignKey(UserModel, on_delete=models.CASCADE) name = models.CharField(_("query name"), max_length=150) status = models.CharField( _("query status"), choices=QueryStatus.choices, default=QueryStatus.ACTIVE, ) is_favorite = models.BooleanField(_("favorite"), default=False) date_created = models.DateTimeField(_("date created"), auto_now_add=True) class Meta(object): app_label = "app" db_table = "query" constraints = [ models.UniqueConstraint( fields=("user",), condition=Q(is_favorite=True), name="unique_favorite_per_user", ) ] So in my system, users can create queries and set them as favorites, but each user can only have 1 favorite query, so I created the UniqueConstraint to enforce that business rule. Then I would have an endpoint to set a query as favorite, but is there a way for me to update that field without having to check all is_favorite fields of each user and manually setting them to False? I found this StackOverflow post from 2 years ago that proposes a solution, but this solution is not working for me, I would really appreciate some help -
