Django Microsoft Graph Authentication
I'd like users to be able to login to my Django app using their Microsoft personal, work or school account. I have no interest in any profile or other data from the user's account. I just want authentication. I've been playing with django-allauth and and Azure portal and have successfully set things up so I can log in with my personal outlook.com account. I've set the AD tenants up to allow for personal and institutional accounts. I've successfully served the .wellknown json and was able to verify the app in Azure. I run into trouble when I try to log in with a Microsoft 365 work or school account. The consent form shows the app as "unverified" and indicates that the app wants profile information and to store data. I ended up in a rabbit hole of Microsoft AD documentation about MPN IDs and such. Before I go further I want to know if I what I want to do is even possible. Keeping in mind that I'm not interested in profile information, can I achieve authentication in Django with a users Microsoft Work or School account? If so, what do I have to do? -
Django : Define url with the pk value in the middle and add it to the template
After the login, the user is redirected to a page where he has to select a contract value. The value selected redirects him to the specific home page. It is the home page concerning the contract where there are several apps. The structure of the URLS is : urlpatterns = [ path('selectcontrat', views.selectcontrat, name='selectcontrat'), path('home/<int:id_contrat>/', views.home, name="home"), path('home/<int:id_contrat>/upload', views.upload, name="upload"), ] The views : @authenticated_user def selectcontrat(request) : context = initialize_context(request) form_client = SelectClient(request.POST, user=request.user) if form_client.is_valid(): id_contrat = request.POST.get("ID_Customer") return redirect(reverse('home', args=(id_contrat,))) context['form_client'] = form_client return render(request, 'base/selectcontrat.html', context) @authenticated_user @check_user_rights() def home(request, id_contrat=None): context = initialize_context(request) context["id_contrat"] = id_contrat return render(request, 'home.html', context) @authenticated_user def upload(request, id_contrat=None): bla_bla_bla return render(request, 'base/upload.html', context) How do I add the urls/links in the template for the app "Upload Files" with the id_contrat value in the middle ?

Cross-Origin-Opener-Policy header error when making GET request in Django
I'm making a stock app which displays live market data via Alpaca API. The error is The Cross-Origin-Opener-Policy header has been ignored, because the URL's origin was untrustworthy. It was defined either in the final response or a redirect. Please deliver the response using the HTTPS protocol. You can also use the 'localhost' origin instead. Here's how I'm making the request: symbol = 'AAPL' url = f'https://data.alpaca.markets/v2/stocks/{symbol}/trades/latest' requests.get(url, headers={ 'APCA-API-KEY-ID': API-KEY-ID, 'APCA-API-SECRET-KEY': API-SECRET-KEY, }) My request works when market is closed, but not open. However, if I run the code in a console during open hours, it still works so the API endpoint should be correct. In Django settings, I have: ALLOWED_HOSTS = ['market-master.herokuapp.com'] CSRF_TRUSTED_ORIGINS = ['https://market-master.herokuapp.com'] My site is https, is there an additional header I'm missing? I'm not sure how to "deliver the response using HTTPS protocol". -

Validationerror: "choose a valid option" on related field in ModelForm
I have a Model Inserzione related to a Model Servizio: class Inserzione(models.Model): servizio = models.OneToOneField( 'hub.Servizio', on_delete=models.CASCADE, null=True, default=None, related_name='+' ) In my InserzioneModelForm I want to restrict the choices of Servizio, I don't want all Servizio instances to be included.

The problem is that the form_valid() method returns False. It return a ValidationError {'servizio': [ValidationError(["Choose a valid option. The selected option is not between the available ones"])]} But it's actually an existing and valid Servizio instance. Here the incriminated form field in my template: <div class="controls "> <select name="servizio" class="select form-control" required="" id="id_servizio"> <option value="" selected="">---------</option> <option value="1">Corso Sicurezza sul Lavoro</option> <!--other options--> </select> </div> Any help is really aprreciated, thanks. -
