Error Encountered: OrganizationFromTenantGuidNotFound
Error Encountered: OrganizationFromTenantGuidNotFound We are encountering an error related to Microsoft Graph API integration in our Django application. Specifically, the error message is: { "error": { "code": "OrganizationFromTenantGuidNotFound", "message": "The tenant for tenant guid 'e01c8511-af06-4cad-9b24-a63b9da7b0fc' does not exist.", "innerError": { "oAuthEventOperationId": "8b058e01-f527-4afe-9294-ee28aec98e19", "oAuthEventcV": "D3A3Bd+uExjl4MwXmDgIqw.1.1", "errorUrl": "https://aka.ms/autherrors#error-InvalidTenant", "requestId": "fda9cb55-b436-4590-b3b3-3d847ee7e931", "date": "2024-09-16T18:42:41" } } } This happens when trying to authenticate using Azure AD and fetch emails via Microsoft Graph API. The decoded token shows a valid tenant_id, client_id, and permissions, but we suspect there might be an issue with the tenant configuration or app registration on Azure. At the moment, using the token, I can get a list of all users. However, when I go to the information on a specific user, an error occurs. However, on the application side, no errors are displayed. My main task is to configure the functionality of sending messages from my application, so that messages sent to the user's address are visible in the application (also when sending a message to a user). https://graph.microsoft.com/v1.0/users/ { "@odata.context": "https://graph.microsoft.com/v1.0/$metadata#users", "value": [ { "businessPhones": [], "displayName": "Demo Mail", "givenName": null, "jobTitle": null, "mail": "demotest@tester.com, "mobilePhone": null, "officeLocation": null, "preferredLanguage": null, "surname": null, "userPrincipalName": "---", "id": "d028f0d4-0838-4925-8eeb-5f6651b6cfb1" }, ] … -
Setting up React with DRF?
Currently, I'm following some lessons on my course and building a social media website project for assessment in future. I am currently stuck with getting my React App built within a Django Rest Framework App to display even the default React page when hosting Live Server, I will link my repo below if it helps I feel like I have gone in circles now as I'm not fully clued in on a full stack project yet (hence trying to get it together). Very much appreciate if anyone could take a look and help me out. I am a bit of a noob so may be obvious and I'm missing something entirely. https://github.com/conor-timmis/Better-You So far I've been dabbling with the Views & urls of the main app, but not sure where to go from there. Lessons have not really explained this so much, only creating the apps separately then linking them together, but mention building within one repo instead with a full app but I am building from scratch so that's not really an option. (I have tried building my app and putting them into static as I read that in another thread but didn't have any luck with that). -
How do you serve a generated file using Django?
For example, the Django sitemap middleware, generates a sitemap and then serves it from localhost:8000/sitemap.xml. If I were to serve a file in a similar manner, following the same url structure, how would I do this? I have a view and urls file: class FileView(View): def get(self, request): return HttpResponse(open('myfile.xml').read(), content_type='text/xml') # urls.py urlpatterns = [ path( '/myfile.xml', PageView.as_view() ) ] This will fail to render with a 404, and will constantly append a / to the url, so it looks for localhost:8000/myfile.xml/. However, if I change my urlpatterns to use '/myfile', without the file extension, it renders the file correctly. Is there a correct way to serve this using the file exentsion without resorting to dropping it into static files? -
Not able to serve React build files with Django
I have been trying to serve my dist files of React frontend app to my Django project. However, the browser keeps refusing to serve static files and throws the error described below: > Refused to apply style from 'http://localhost:8000/static/my-react-app/assets/index-CgY6hLMH.css' because its MIME type ('text/html') is not a supported stylesheet MIME type, and strict MIME checking is enabled. > Refused to apply style from 'http://localhost:8000/static/my-react-app/assets/index-CgY6hLMH.css' because its MIME type ('text/html') is not a supported stylesheet MIME type, and strict MIME checking is enabled. > index-LlsxC_Wu.js:1 Failed to load module script: Expected a JavaScript module script but the server responded with a MIME type of "text/html".

Can I configure multiple timeouts for pgbouncer from my django settings?
I am trying to add pgbouncer to my architecture. I know that I can set various pgbouncer configuration settings in the pgbouncer.ini file. I want to replace postgresql with pgbouncer in my django settings, however, my django configuration currently uses different timeouts depending on the purpose of the connection. For example, I want a longer timeout for connections intended to perform database migrations. DATABASES = { "default": { "ENGINE": "django.db.backends.postgresql", # <Other settings ...> "OPTIONS": { "options": f"-c statement_timeout={90 * 1000}", }, }, "migration": { "ENGINE": "django.db.backends.postgresql", # <The same other settings as above ...> "OPTIONS": { "options": f"-c statement_timeout={120 * 1000}", }, }, } I have read the pgbouncer documentation and I 1haven't found anything that quite solves this problem. -

DRF getting AttributeError while trying to post data
I'm creating a user registration API in DRF using a Profile model with a OneToOne relationship with Django's default User Model. I have created a serializer with User model and defined the fields of Profile as serializer fields. The problem is when I post the data, though the user and profile are saved in the database I'm getting this error error AttributeError at /auth/registration Got AttributeError when attempting to get a value for field address on serializer UserRegistrationSerializer. The serializer field might be named incorrectly and not match any attribute or key on the User instance. Original exception text was: 'User' object has no attribute 'address'. using write_only with address seems to solve the problem but I want to understand why is this happening and how this view accessing this address field why it ignores the phone_number and date_of_birth and doesn't give me errors on those. Any input will be helpful. Thanks! Here is my code for the model, serializer, and view. #models.py class Profile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) date_of_birth = models.DateField(null=True) phone_number = models.CharField(null=True, max_length=30) address = models.CharField(max_length=250) def __str__(self): return f'Profile of {self.user.username}' #Serializer.py class UserRegistrationSerializer(serializers.ModelSerializer): phone_number = serializers.CharField(required=False, max_length=30) date_of_birth = serializers.DateField(required=False) address = serializers.CharField(max_length=250) password = … -
How should I approach in developing this computer vision project? Dog Pooping/Elimination/Urination Detector w/ alerts through RTSP camera, Web App
I am currently developing a project which aims to develop a Dog Pooping/Elimination/Urination Detector using YOLOv8, with sound alerts to deter from designated spots in which the camera's vision range allows. This application would be viewable through a web page w/ a login portal. Stack: Python, Django, YOLOv8, OpenCV, HTML, CSS, JS I'm having a number of problems first is I'm not sure whether I'm using the right model for this project, I'm currently doing transfer learning using yolov8s.pt and training on a dataset with 1 class, pooping dogs. Here's how it looks: results = model.train(data="config.yaml", epochs=100, patience=15, batch=4, workers=6, device=[0]) However, over numerous attempts and curating the dataset I seem to always get no detections at all, and when I do get detections they're always of false positives. Could it be that object detection is the wrong choice, would pose estimation be better given the goal of the project? Second, I can't find a way to make the RTSP camera be publicly available, I tried looking up port-forwarding but it wasn't possible to the limitations of my router and my ISP. And lastly, aside from a dog pooping/elimination/urination, I would also want the system to be able to identify … -

ECS task timeouts connecting to RDS
My ECS container will connect to my RDS database initially and can even run a query. However very quickly after boot up, the connection will time out. The error sometimes looks like a DNS one with the error message of: OperationalError('[Errno -3] Temporary failure in name resolution') Sometimes its a connection timeout: OperationalError('connection timeout expired') Notes and things I've tried: Security group has 5432 open, but I've tried having all ports open. Same VPC and different VPC My App Runner app can connect to the DB flawlessly (same code) My computer can connect to the database (same code) EC2 instances can connect to the database (same code) ECS container's role with RDS access, which doesn't make sense but I'm grasping at straws RDS is publicly accessible I'm running Django 5.1 on Python 3.12. I'm seriously out of solutions and am considering migrating off ECS to something else. -
Django redirect is blocked by CORS
My django redirects are blocked by CORS, even though I did everything to set up CORS: I installed django-cors-headers in the virtual environment, I added corsheaders to the INSTALLED_APPS and I added corsheaders.middleware.CorsMiddleware to the top of MIDDLEWARE, I also added this to the bottom of my settings.py file: CORS_ALLOW_ALL_ORIGINS = True CORS_ALLOW_HEADERS = [ 'content-type', 'authorization', 'x-csrftoken', ] CORS_ALLOW_METHODS = [ 'GET', 'POST', 'PUT', 'PATCH', 'DELETE', 'OPTIONS', ] CORS_ALLOW_CREDENTIALS = True As well as refreshing my page, restarting the server and VSCode, clearing my cache, and using an incognito window, nothing works. The redirect is redirect("https://google.com/") The result is always the same, it says that localhost:8000 was blocked by CORS, and that the preflight request doesn't pass the access control check, because it doesn't have an ACAO header. -
How to Handle CSRF for iFrames in Django with Multiple Whitelabel Sites Without Using a Domain Whitelist?
I’m building a whitelabel solution using Django, where my clients can embed forms from my application within their websites using iFrames. However, I’m running into a problem with CSRF protection when the form is submitted from these external sites, resulting in a 403 Forbidden error due to "CSRF verification failed." My Setup: **Framework: ** Django 4.x with CSRF protection enabled. Use Case: Multiple clients embed our form (rendered via Django templates) into their websites. Users submit the form from these external domains. Issue: Since the CSRF token relies on cookies and cross-origin policies, the CSRF token isn’t included in the form submission, leading to a verification failure. Constraints: No API Calls: The form is rendered server-side using Django templates, and we’re not using a frontend framework like React or Vue, so API-based solutions aren’t suitable. Dynamic Embedding: There’s no fixed number of client websites that can use the form, so maintaining a domain whitelist for CSRF exemption is not scalable. Security: I still want to maintain CSRF protection for security purposes. What I've Tried: Disabling CSRF Middleware: Works, but it compromises security, so it's not a viable long-term solution.

I have an app. The app has users, posts, comments to post etc(it's kinda blog). The task is to limit users from editing objects, that do not belong to the user. Like User can not edit posts made by another one(or comments). I want to write a decorator for it in order to authorize user's actions. So i did, but now i got an error ValueError: The view blog.views.wrapper didn't return an HttpResponse object. It returned None instead. My code: def authorize(func): def wrapper(*args, **kwargs): if kwargs.get('post_id'): instance = get_object_or_404(Post, id=kwargs.get('post_id')) if not args[0].user.id == instance.author_id: return redirect( 'blog:post_detail', post_id=kwargs.get('post_id') ) kwargs.update({'instance': instance}) elif kwargs.get('comment_id'): instance = get_object_or_404(Comment, id=kwargs.get('comment_id')) if not args[0].user.id == instance.author_id: return redirect( 'blog:post_detail', post_id=kwargs.get('post_id') ) kwargs.update({'instance': instance}) func(*args, **kwargs) return wrapper @login_required @authorize def edit_post(request, post_id, instance=None): instance = get_object_or_404(Post, id=post_id) form = PostForm(request.POST or None, instance=instance) context = {'form': form} if form.is_valid(): form.save() return render(request, 'blog/create.html', context) What am i doing wrong? -
New branch in github cannot run manage.py - ImportError: Couldn't import Django
I have a perfectly working static Django site on my main branch in Github. But as soon as a make a second branch branch2 off that exact Django site of my main branch python manage.py runserver gives me this error (but the venv activates with no issues on the new branches before running manage.py) : ** "ImportError: Couldn't import Django. Are you sure it's installed and available on your PYTHONPATH environment variable? Did you forget to activate a virtual environment?"** How can I setup my Django/python across these successive branches to run without issues? I am using Django 5.1 and Python 3.12.1 I just want the manage.py server to run on each successive branch I create -
How do calls of models.Manager and custom managers work?
The following question was asked by a different user that subsequently removed the question. But I think it is useful to "dig" a bit in how Django's manager logic works. I extended the models.Manager class and created a custom manager. class PublishedManager(models.Manager): def get_queryset(self): return super().get_queryset().filter(status=Post.Status.PUBLISHED) It's more than understandable, BUT how do calls of managers work? objects = models.Manager() # The default manager. published = PublishedManager() # Our custom manager. I don't address get_queryset() method, I just call constructors. Then how does it work? -
How to do aggregate raw sql with julian date in sqlite (with django)
I'm using sqlite3 and django. I wish to calculate the average for all the number of days between last_played and now. (Last_played is just a datetime field). I have so far: avg_days_last_played_sql = """ AVG(julianday('now') - julianday(played_at)) """ # Annotate the average days last played average_days_last_played = Song.objects.aggregate( avg_days_last_played=RawSQL(avg_days_last_played_sql, []) )['avg_days_last_played'] But it gives the error: TypeError: avg_days_last_played is not an aggregate expression
