Is there a solution to type hint a django annotation?
I have a django project which I am trying to type and add type checking through mypy. I want to use django annotations to get more informations about an object. This operation adds properties to a class already declared. The package django-stubs already provides a typing class WithAnnotations that should do the work but it doesn't. To be clear, I simply want this code to pass mypy from django.db import models class User(models.Model): first_name: models.CharField() last_name: models.CharField() class Team(models.Model): users: models.ManyToManyField(User) class House(models.Model): inhabitants: models.ManyToManyField(User) users = User.objects.all() for user in users: print(user.first_name) users_with_teams = Users.objects.all().annotate(teams_ids=ArrayAgg(...)) users_with_teams_and_houses = users_with_teams.annotate(houses_ids=ArrayAgg(...)) for user in users_with_teams: print(user.first_name) print(user.teams_ids) print(user.houses_ids) If I try to run it I get errors object User has no attribute teams_ids or object User has no attribute houses_ids I thought it would be nice to have it in functions: from typing import TypeVar T = TypeVar("T") def annotate_teams(query: QuerySet[T]) -> QuerySet[SomethingElseButWhat]: return query.annotate(teams_ids=ArrayAgg(...)) but I don't know which type my function should return. Does any of you know if what I am looking for is possible ? -
What's the proper way to conclude the OAuth2 flow in Django?
To keep the story short, I've acquired all the necessary tokens from Google using the "auth code" flow. So currently, I have the following tokens at my disposal: 1. access_token 2. refresh_token 3. id_token 4. verified JWT token The next step is to log in the user using the provided login() method from django.contrib.auth. This creates a sessionId which is then used to "verify" that a user is logged in. In my current development setup, I'm just using the email from the JWT token to create the session: from django.contrib.auth import login from django.contrib.auth.models import User def login_provider(request): # 1. Get the user info from JWT token (assume I have it) user_obj = jwt_token.user # 2. Create a Django user instance user, created = User.objects.get_or_create(email=user_obj.email) # 3. Log the user in login(request, user) # 4. Redirect the user somewhere else return redirect("somewhere-else/") I've taken all the necessary steps to ensure the Google OAuth2 flow part is secure but am I correct in assuming that this way of logging the user in isn't secure since I'm basically using just the users email? What's the correct way to do this? -
Logs not getting sent to Datadog when running Django shell inside a container
The logs that are created by the code running inside the container do get sent to Datadog, but when I'm in a shell session inside the container those logs get outputted in the terminal, but not sent to Datadog. Therefore, once I leave the session (if I don't copy and paste the logs into a file), they are forever lost. TL;DR; Datadog Agent runs inside the container, but not inside the shell session inside the container How can I make it so that the logs produced inside the shell session also get sent to Datadog ? -
How to add element in Django QuerySet?
I have model Report and GroupReport. They have many-to-many relation. I can easily get QuerySet[GroupReport] for all GroupReport instance: Group Name 1: Report Name 1 Report Name 2 Group Name 2: Report Name 2 Report Name 10 ... and etc. But i need to add entry "Total Reports" to QuerySet[GroupReport]: Group All reports: Report Name 1 Report Name 2 Report Name 5 ... and another reports from QuerySet[Report] I can't store group "Total Reports" in database because using object permissions for QuerySets. It is necessary to generate the group dynamically. My Serializer expect correct queryset. How can i do this? I tried to do it something like this: def get_queryset(self): groups = get_objects_for_user( user=self.request.user, perms=view_reportgroup, klass=ReportGroup.actived_objects, accept_global_perms=False ) reports = get_objects_for_user( user=self.request.user, perms=view_report, klass=Report.actived_objects, accept_global_perms=False ) total = ReportStorage(id=None, name='Total Reports') total.reports.set( Report.actived_objects.filter( Q(id__in=reports) | Q(groups__in=groups) ).distinct() ) return (groups | total).prefetch_related( Prefetch( 'reports', queryset=ReportStorage.prefetch_related( Prefetch( 'reportstorage', queryset=super().get_queryset() ) ) ) ) But got expected error: "needs to have a value for field 'id' bla-bla..." for total.reports.set. I was also thinking about adding ReportStorage to groups._result_cache. But I don't understand how it should look. Maybe there are more correct ways such as custom SQL, converting QuerySet to List? -

Create non existing tag with Django-select2
I am using django-select2 to autocomplete a tag field on a model. I would like to let user write any tag in the field, and create it if the tag doesn't exists... # models.py class Version(models.Model): ... tags = models.ManyToManyField(Tag, blank=True) class VersionTagWidget(s2forms.ModelSelect2TagWidget): search_fields = [ "nom__icontains", ] class VersionEditViewForm(forms.ModelForm): def __init__(self, *args, **kwargs): ... class Meta: model = Version widgets = { "tags": VersionTagWidget, } I can autocomplete value (and select in a dynamic dropdown), but if type in a non-existing (in my example, I entered 'DoesNotExist') value and submit the form, I get : Exception Value: Field 'id' expected a number but got 'DoesNotExist'.

Adding laos language in Django
I have added the langauge laos in settings.py as follows LANGUAGES = [ ("en", _("English")), ("my", _("Burmese")), ("fr", _("French")), ("km", _("Khmer")), ("th", _("Thai")), ("vi", _("Vietnamese")), ("lo", _("Lao")), ] However, when I load my application I get the error. KeyError at / 'Unknown language code lo.' Seems like the current version of Django does not support the language. Is there a way I can manually add a none existing language in Django? Thank you in-advance. -
Why companies still prefer Django over Fast API for REST APIs developments
Can I get thoughts from working professionals in python domain over why companies still prefer Django over Fast API for REST APIs developments. In python world I see more opportunity of Django over Fast API. So wanted to know the reason about this preference. As in multiple blogs and Generative AI I got to know that Fast API outperforms Django. -
Pydantic/Django Ninja use only existing keys (even with None)

In Django REST Framework, why does raising serializers.ValidationError return errors in different format in validate() and create() methods?

IIS does not pass on REMOTE_USER with HTTP Platform Handler
I have a Django server application that I am running with IIS on Windows Server (using HTTP Platform Handler). I would like to use Windows Authentication. I have enabled Windows Authentication in the server settings in IIS. If I understood the documentation correctly, I would expect that for each request, IIS would then send a REMOTE_USER object in the HTTP request to the Django server. However, this does not happen. REMOTE_USER is neither a server environment variable nor in request.META. In the IIS logs (The logs in C:\inetpub) I can see that it recognises my user, but IIS does not seem to forward that user information to the Django server. A line in the logs looks e.g. as follows: 2024-12-11 12:10:20 <SERVER IP> GET /<PATH> - <PORT> <DOMAIN>\<USERNAME> <CLIENT IP> <BROWSER DATA> ... So, IIS clearly does perform Windows Authentication, and it works, but that information somehow never makes it to the Django server. I have tried using Django's RemoteUserMiddleware, which does not change the behaviour. Is there some additional setting that I am missing? -

what is the correct way to pass context to a playwright function when using python django as the basis for a webapp?
I've got a web app that I built first with Flask, then totally rebuilt with Django, to get advantage of the admin interface. It builds a flyer for a kids football match, using the context to overlay on a background image via css absolute position. Once the coach is happy with the image, a button calls a Generate function, which opens a browser with playwright and passes the session data to recreate the image and allow the coach to download it. When the coach is viewing the image the text fields are populated from the context. this all works fine. def image(request): ... some other bits ... for key in request.session.keys(): context[key] = request.session[key] return render(request, 'coaches/image.html', context) this is an example from the template that shows how the text is added from context. I'm using Django Template engine. {% for player in squad %} <td> <span class="playernumber">{{ player.number }}</span> <span class="playerfirstname">{{ player.first }}</span> <span class="playerlastname">{{ player.last }}</span> </td> {% if forloop.counter|divisibleby:2 %} </tr> <tr> {% endif %} {% endfor %} the same template code doesnt work when the playwright browser view is invoked. the view is fine, the template is fine, but calling the variables from context doesnt work. … -

Custom Link on Column
I am working with django-tables2 to display some patient information on a page. I am creating the table like this: class PatientListView(tables.Table): name = tables.Column('Practice') patientid = tables.Column() firstname = tables.Column() lastname = tables.Column() dob = tables.Column() addressline1 = tables.Column() addressline2 = tables.Column() city = tables.Column() state = tables.Column() zipcode = tables.Column() class Meta: template_name = 'django_tables2/bootstrap.html' and then I am populating the table in my view with the result of an sql query like this: table = PatientListView(patients) I would like to ideally make each row of the table clickable so clicking anywhere on the table row would take me to a separate url defined by me. I would also settle for having a specific cell to click that would take me to a separate url. I have seen the linkify option, but from what I've read of the documentation it looks like linkify does redirects to django model pages, but I am not using models for this database as the database is created and managed by another application, and I am just reading and displaying that information. If django-tables2 is not the right solution for this issue I am open to hearing suggestions of other ways I can … -

Django DRF - Accessing data from POST request forwarded through ngrok
I'm working on a Django REST framework (DRF) API that receives data forwarded from an external endpoint through ngrok. Here's the relevant view code: Python class MessageReceiver(generics.CreateAPIView): def post(self, request, org_id, channel_name): data = request.data if data: return Response( data={ "data": data }, status=status.HTTP_200_OK ) return Response(data={'message': 'No data received'}, status=status.HTTP_400_BAD_REQUEST) Use code with caution. My question is: since this is a POST request, I'm unable to access the original forwarded data directly. As I understand, POST requests require a payload to be sent along with the request. How can I effectively access and process the data within request.data in this scenario before I have to hit the endpoint again? -

Selection query create by use select_related('regulation') I added required serializers and models below. Serializers Crossroad class ReadonlyCrossroadFullDataSerializer(serializers.ModelSerializer): time_loads = CrossroadTimeLoadSerializer(many=True) sides = CrossroadSideFullDataSerializer(many=True) directions = CrossroadDirectionFullDataSerializer(many=True) class Meta: model = Crossroad fields = "__all__" CrossrodDirection class CrossroadDirectionFullDataSerializer(serializers.ModelSerializer): time_params = CrossroadDirectionTimeParamsSerializer(many=True) regulation = CrossroadDirectionRegulationSerializer(allow_null=True, default=None) class Meta: model = CrossroadDirection fields = "__all__" Regulation class CrossroadDirectionRegulationSerializer(serializers.ModelSerializer): class Meta: model = CrossroadDirectionRegulation fields = "__all__" Models CrossrodDirection class CrossroadDirection(models.Model): class Meta: constraints = ( models.UniqueConstraint( "input_point", "output_point", name="unique_crossroad_direction__input_output_points", ), ) crossroad = models.ForeignKey( Crossroad, on_delete=models.CASCADE, related_name="directions", ) input_point = models.ForeignKey( CrossroadPoint, on_delete=models.CASCADE, related_name="direction_input_point", ) output_point = models.ForeignKey( CrossroadPoint, on_delete=models.CASCADE, related_name="direction_output_point", ) probability = models.FloatField(default=1) Regulation class CrossroadDirectionRegulation(models.Model): crossroad_direction = models.ForeignKey( CrossroadDirection, on_delete=models.CASCADE, unique=True, related_name="regulation", ) cycle_duration = models.IntegerField(default=180) green_signal_phase = models.IntegerField(default=60) If I change Regulation serializer as below then crossroad serializer work successful - if there is regulation then … -
experiencing intermittent apache error AH01630
We have two different django apps running on a server (Centos7), using django manage.py runmodwsgi (python module mod_wsgi). Both apps are running fine, and have been for a few years. The odd thing we are running into is that every 10-12 days or so, we get a 403 Forbidden message in the browser.

Restarting the web server fixes the issue (and the htdocs directory reappears). Both apps experience this issue. Sometimes at the same time, sometimes not. Both apps otherwise run fine. We would really like to find a solution to this annoying issue. Googling this error just gives me advice on the httpd.conf file content, but I have not been able to find any help on this when the issue is intermittent the way I'm describing it here. I have plotted the date/times of the AH01630 errors, and find that this happens at an oddly regular … -
Django-tenant: Accessing tenant data in public domain
I was working on Django-tenant where I have tenant model called Appointment now I want to get the appointment of a specific tenant from the public domain but I'm having an issue when rendering it in the template class OrganizationAppointmentList(LoginRequiredMixin, TenantMixin, ListView): template_name = 'main/appointments/list_appointment.html' paginate_by = 10 def get_queryset(self): tenant_id = self.kwargs.get('pk') try: tenant = Organization.objects.get(id=tenant_id) self.schema_name = tenant.schema_name with schema_context(self.schema_name): queryset = Appointment.objects.all() return queryset except Organization.DoesNotExist: raise Http404("Tenant not found") except Exception as e: raise Http404(f"Error accessing tenant data: {e}") def paginate_queryset(self, queryset, page_size): with schema_context(self.schema_name): return super().paginate_queryset(queryset, page_size) def get_context_data(self, **kwargs): with schema_context(self.schema_name): context = super().get_context_data(**kwargs) tenant_id = self.kwargs.get('pk') context['tenant_id'] = tenant_id context['appointments'] = Appointment.objects.all() print(context['appointments']) return context In above code the print(context['appointments']) Is giving the exact data but while rendering it in template it shows LINE 1: ...app_appointment"."al_appointment_updated_at" FROM "appointme... and if I left the template empty the error does not show is it something that I'm missing?? I'm trying to get the specific tenant model data in public domain
