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)
having an app in Django Ninja with schemas: class NumericalFilterSchema(Schema): gt: Optional[int] = None lt: Optional[int] = None gte: Optional[int] = None lte: Optional[int] = None exact: Optional[int] = None class Config(Schema.Config): extra = "forbid" class StringFilterSchema(Schema): contains: Optional[str] = None icontains: Optional[str] = None exact: Optional[str] = None class Config(Schema.Config): extra = "forbid" class InputsSchema(Schema): major_version: Optional[NumericalFilterSchema] = None app_name: Optional[StringFilterSchema] = None class Config(Schema.Config): extra = "forbid" class InputSchema(Schema): filters: InputsSchema class Config(Schema.Config): extra = "forbid" which I then use in the endpoint like this: @router_v1.post( "/apps", tags=["..."], auth=AuthBearer(), ) def dynamic_filter(request: HttpRequest, filters: InputsSchema): query = Q() # import ipdb # ipdb.set_trace() for key, value in filters.dict(exclude_none=True).items(): # key = translate_field(key) # just abstraction between endpoint keys to db keys if isinstance(value, dict): for k, v in value.items(): if v is not None: query &= Q(**{f"{key}__{k}": v}) else: query &= Q(**{key: value}) results = Apps.objects.filter(query) ... Problem: As you can see in the query building I am excluding all the None values which is fine in the most cases for example: { "major_version": { "exact": 3 }, "app_name": { "icontains": "google" } } this will return schema InputsSchema(major_version=NumericalFilterSchema(gt=None, lt=None, gte=None, lte=None, exact=3), app_name=StringFilterSchema(contains=None, icontains='google', exact=None)) which is … -

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? -

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. When checking the mod_wsgi apache error log (/tmp/mod_wsgi-localhost:8080:1999/error_log), there is nothing except the error below, which is triggered whenever the user unsuccessfully tries to access the app. AH01630: client denied by server configuration: /tmp/mod_wsgi-localhost:8080:1999/htdocs After receiving this error, I can see that the htdocs directory that is referenced in the error doesn't exist. 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 … -

How can I programatically authenticate a user in Auth.js?
I have a Django application with authenticated (logged-in) users. I have another (Svelte) application using Auth.js (https://authjs.dev) for authentication, currently set up with github/facebook/linkedin. Now I want to send a user from the Django application to the Svelte application, and automagically (i) create the user in the Svelte application if they don't exist, and (ii) log them in to the Svelte application. I want the end-user experience to be like a regular redirect from one page to the other staying logged-in in both places. I'm stuck at the part where the user arrives in the Svelte application and I need to create a session. Does Auth.js have any way of doing this without going through a "provider"? -
PDF file cannot be opened, when generated with Django and WeasyPrint
I recently began trying generating PDF reports with Django and Weasyprint, but I cannot make it work somehow. I already have file upload, file download (even PDFs, but already generated ones that were uploaded), CSV generation and download, XLSX generation and download in my application, but I'm not able to return PDFs generated with WeasyPrint so far. I want my users to be able to create reports, and they'll be saved for further new download. So I created this basic model : from django.db import models class HelpdeskReport(models.Model): class Meta: app_label = "helpdesk" db_table = "helpdesk_report" verbose_name = "Helpdesk Report" verbose_name_plural = "Helpdesk Reports" default_permissions = ["view", "add", "delete"] permissions = [ ("download_helpdeskreport", "Can download Heldpesk Report"), ] def _report_path(instance, filename) -> str: return f"helpdesk/reports/{instance.id}" id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False) name = models.CharField(max_length=100, unique=True) file = models.FileField(upload_to=_report_path) Since I use service classes, I also did : import uuid from io import BytesIO from django.core.files import File from django.template.loader import render_to_string from weasyprint import HTML class HeldpeskReportService: def create_report(self) -> HelpdeskReport: report_name = f"helpdesk_report_{uuid.uuid4().hex}.pdf" html_source = render_to_string(template_name="reports/global_report.html") html_report = HTML(string=html_source) pdf_report = html_report.write_pdf() # print("check : ", pdf_report[:5]) # It gives proper content beginning (PDF header) pdf_bytes = BytesIO(pdf_report) pdf_file = … -
