Django ORM .distinct() seems to return duplicate results
I have an Event model that represents an Event happening. I have another EventShow model which represents a date and time that the event is taking place. Each event can have multiple shows, so I have a ForeignKey from EventShow to Event as follows - class Event(models.Model): name = models.CharField(max_length=32) # ... and more class EventShow(models.Model): event = models.ForeignKey(Event, on_delete=models.CASCADE, related_name='shows') start_date = models.DateTimeField() I want to get a list of events which have at least one show happening in the future, so in my view I'm calling the ORM like this - events = Event.objects.filter(shows__start_date__gt=now()).prefetch_related('shows').distinct().order_by('shows__start_date') However, I still get the same event showing up multiple times if it has multiple shows. How can I fix this? I looked at the SQL that was being generated by this call - SELECT DISTINCT "core_event"."id", "core_event"."name", "core_eventshow"."start_date" FROM "core_event" INNER JOIN "core_eventshow" ON ("core_event"."id" = "core_eventshow"."event_id") WHERE ("core_eventshow"."start_date" > 2023-08-16 02:48:46.063093) ORDER BY "core_eventshow"."start_date" ASC I'm using SQLite for development. -
Gunicorn & Django: Handle timeout
We run a Django REST API behind Gunicorn (on a Kubernetes Cluster in EKS exposed via AWS ALB). The Gunicorn command: gunicorn config.wsgi --timeout 20 (...) When a request takes over 20 seconds to be processed by Django (due to various reasons), gunicorn will timeout by emitting a SigAbt signal and restart the gunicorn worker. However, this causes an issue in tracking the error in various tools such as Datadog or Sentry which are not able to track the error correctly. Instead, we would like to emit an explicit error (customer error) called TimeoutError. After a thorough investigation, we want to find the best way to raise this TimeoutError at Django Level when the request takes 20 seconds to complete. What would be a recommended solution? -
Django slice then filter queryset
I'm trying to use pgvector to find similar products by name, I've built the embedding on the name, now, when I try to use the method that is stated on the docs for pgvector in order to get the products with a certain distance using ALIAS the query never executed, I tried the other method using group_by which worked the get top 10 for example, but in some cases, top 10 might be too far from being similar to the product, That's why I want to order_by then filter based on the distance only for the 100 in order to ensure that I'm getting similar items, The problem with Django is I can't filter after slicing the queryset, I have a workaround which is: Getting the top 100 ordered by distance and then using their id to filter for the next query which will cause more executing time. (More than 100K records) Is there a better way of doing it, thanks. Slice then filter: result = self.get_queryset().order_by(L2Distance('name_embedding', entry_vector))[:100].alias(distance=L2Distance('name_embedding', entry_vector)).filter(distance__lt=threshold) -

I am getting AnonymousUser for request.user after loggin out in Django. How can I fix this?
I have a view called LogoutView that is decorated with the @permission_classes([IsAuthenticated]) decorator. When I call the get() method on this view, I am getting AnonymousUser for request.user after logging out. I have tried the following things to fix this, but none of them have worked: I have checked the request.user.is_authenticated attribute to make sure that the user is authenticated before logging them out. I have returned a 401 Unauthorized response if the user is not authenticated. I have called the logout() method to log the user out. from rest_framework.views import APIView from rest_framework.response import Response from rest_framework import status from myapp.models import User from django.contrib.auth import authenticate, login, logout import requests from django.shortcuts import get_object_or_404 from django.http import JsonResponse from rest_framework.decorators import api_view, permission_classes from rest_framework.permissions import IsAuthenticated, AllowAny from .models import ChatRoom, UserChatRoom from myapp.serializers import ChatRoomSerializer, UserSerializer from django.contrib.sessions.models import Session from django.contrib.auth import login, authenticate from rest_framework.response import Response from rest_framework.views import APIView from rest_framework import status import requests from .models import User # Make sure you import your User model correctly from rest_framework.permissions import AllowAny class GoogleLoginView(APIView): permission_classes = [AllowAny] def post(self, request): credential = request.data.get('credential') google_response = requests.get(f'https://www.googleapis.com/oauth2/v3/tokeninfo?id_token={credential}') if google_response.status_code == 200: google_data = … -
How can I access templates from an imported Django application?
I want to pip install a Django application and be able to access its templates when adding it to the "INSTALLED_APPS" section in Django project's "settings.py" file. I followed the tutorial here to build a Django app and export it as an installable package, then installed this package into the virtual environment of another Django project. Everything works fine when I add the app's name in INSTALLED_APPS and when I include the urls of the imported app in the project's urls.py file. However, when I run the lightweight server of the Django project and try to access one of the imported app's page, I get a "django.template.exceptions.TemplateDoesNotExist" error. Why would Django allow to access the urls and views of an imported app, but not its templates or templatetags? When running the server and sending a request to it for a specific web page, I was expecting to get this web page (located in the templates of the imported app) to load on my browser. -

Running R code in Python using rpy2 - Kernel dying
I want to run a R code in my pythons jupyter notebook, My plan is to run the model with both R code and python combined in Django server to publish the ML model(I myself din't make the model so I dont know anything about it). People who made the ML model have used both python varaibles in R code and R varibles in python code. So it would be better if I have all of the programs in a single django server. Due to which I want to run the R code in my python jupyter notebook as the first step. I came accros rpy2 and tried using rpy2 for this. But whenever I try to import something from rpy2 my kernel just dies I just did "pip install rpy2" as suggested to install rpy2. Do I need to set a path like this to for the import to work, But I dont know where to set the path of R to set to since I dont have R folder in my libs even after I installed rpy2 using pip Optional Quetion: Also on the side note is it possible to do what I am thinking on running the … -

Microsoft Teams integration for Django self-hosted in AWS
I already spent several hours on Microsoft docs making very little progress for what I believe should be a trivial integration, but apparently it's not. I've a Slack integration (via Slack app, built in Django and hosted on AWS) that works this way: our client installs the app and we receive a single token with the token we can pull all slack workspace accounts once that's done, our app sends 2 types of messages using that same token: a message to a public slack channel a 1-to-1 message to an individual I need to replicate this behaviour for Microsoft Teams. I don't want to use Azure, nor node.js, ideally if I could spin up few endpoints to exchange tokens on Django and some logic to send the messages that would be gold. At this point I will take any wisdom from Teams experts ... Thanks -

How can I add taggit tags to a newly created Django model instance?
I'm unable to add Taggit tags to a newly created Django model instance from within a DRF serializer. When attempting to do use the new instance, the operation fails with list object has no attribute add. class ThingSerializer(serializers.ModelSerializer): def create(self, validated_data): # fails with `list object has no attribute add` thing = Thing.objects.create(**validated_data) custom_tags = validated_data.pop("custom_tags", []) for custom_tag in custom_tags: thing.custom_tags.add( custom_tag.pop("name"), tag_kwargs=custom_tag ) thing.save() def create_with_hack(self, validated_data): # works after fetching the record from DB thing = Thing.objects.create(**validated_data) thing_ = Thing.objects.get(pk=thing.id) custom_tags = validated_data.pop("custom_tags", []) for custom_tag in custom_tags: thing_.custom_tags.add( custom_tag.pop("name"), tag_kwargs=custom_tag ) thing_.save() As noted above, I'm able to work around this by first explicitly fetching record from the database but that is undesirable.

Update the text entry widget in a django_jsonform JSONField
I'm using a JSONField from django_transform for a json column in my DB. On the admin page Django renders a nice form that allows users to add entries to the json according to the schema. I want to switch out the text entry input field (a Textinput, I think) for string inputs in the JSONField form with a rich text entry widget. I've tried overwriting the JSONField widget with a rich text widget (I'm using TinyMCE) but that replaces the whole thing and just prints the dumped json string in it. Is it possible to override internal widgets of the JSONField form? -

Django - How to fix multiple pks in url?
I currently have a live search functionality built out mostly working how I want. Functionality works like this: A user searches a word on the search bar. Then the user gets a display of suggested searches that includes text and an image. The user clicks on the text/image from the suggested searches that they want and then the user goes to the template page that includes the primary key in the url. The Problem: When the user is on the template page that includes the primary key and another form submission is made. An additional pk gets added to the URL. Example: http://127.0.0.1:8000/1/2/ This results in Page Not Found 404. How do i fix this? After a user makes another submission I just need the url updated with the new primary key. So this: http://127.0.0.1:8000/1/2/ needs to be this http://127.0.0.1:8000/2/ Any help is gladly appreciated. Thanks! Code Below: urls.py: urlpatterns = [ path('', account_view_home, name='home'), # Below are the urls where the live search is enabled # path ('game_details/', search_results_view, name="game_details"), path ('<pk>/', search_detail_view, name="detail") ] views.py def search_detail_view(request,pk): obj = get_object_or_404(Game_Info, id=pk) user_prices = Shopping_Prices.objects.all() game_leaderboard = User_Info.objects.all() # return render(request, 'detail.html', {'obj':obj}) if request.user.is_authenticated: user_profile = User_Info.objects.filter(user=request.user) context … -

Is there a way to know what triggered the beforeunload?
I have a page on my Django app with a form. I would like to alert users if they try to exit the page without submitting their form. I implemented this with the beforeunload method, written below: window.addEventListener('beforeunload', function (e) { e.preventDefault(); e.returnValue = ''; }); However, this also raises an alert when a user submits a page. Is there a way to identify which event is triggering the beforeunload (either submit or exiting, refreshing,etc.)? -
Form Validation Errors Not Displayed in my HTML Template
I developed a login and registration system using Django on a single HTML page with a tabbing system. But, I encountered an error: upon registering, the page just refreshes. To troubleshoot, I debugged by printing errors to the console. It printed that the form is invalid. I intentionally provided invalid details to troubleshoot, like entering a password similar to the username or a password that isn't longer than 8 characters. It printed that in the console, but I want it to show the errors in the HTML template for each field. So, I wrote a login-register view. Everything seems to be okay in the view, but it still isn't showing the errors in the HTML template.
