How to call celery task in Django from Fastapi app
I have two apps (Django and FastApi) that use Celery to do some background task. Now, I need to communicate the two applications and I have thought about reusing the queues that celery uses (I don't really know if it is the best way to do it).The two apps are using the same broker and all are in Docker containers. I wolud like to execute a task that is in the django app when calling a route in the FastApi app. Django app celery.py app = Celery("app_1") app.config_from_object("django.conf:settings", namespace="CELERY") app.autodiscover_tasks(lambda: settings.INSTALLED_APPS) settings.py ...

How to make Django Rest Framework Serializers to work different with GET and POST request
Actually, I have am creating the API for Bookmark manager, where I will be having CRUD operations on Bookmark, Collection and Tags Here I am using the BookmarkSerializer for serialization, class BookmarkSerializer(serializers.ModelSerializer): class Meta: model = Bookmark fields = "__all__" def create(self, validated_data): tags_data = validated_data.pop('tags', []) bookmark = Bookmark.objects.create(**validated_data) for tag_data in tags_data: bookmark.tags.add(tag_data) return bookmark and Bookmark model is like class Bookmark(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE) url = models.URLField() thumbnail_url = models.URLField(blank=True, default="https://site.image.jpg") title = models.CharField(max_length=512, blank=True) description = models.TextField(blank=True) note = models.TextField(blank=True) tags = models.ManyToManyField("Tag", blank=True) is_favorite = models.BooleanField(default=False) created_at = models.DateTimeField(auto_now_add=True) collection = models.ForeignKey("Collection", on_delete=models.CASCADE, blank=True, null=True) def __str__(self): return self.title My requirement is that, when GET request comes in I will return all information, and when POST request comes in I will create the new instance of Bookmark model.

ModelViewSet routes and methods

Attach listener to Azure Active Directory Microsoft login for Django
I'm writing an app using Django that uses exclusively MS login to authenticate users. I've followed the same structure as the sample code set up at their Django tutorial. https://github.com/Azure-Samples/ms-identity-python-django-tutorial/tree/main/1-Authentication/sign-in, where it uses some middleware and Django adapters provided by a seemingly undocumented and unused library they've created at https://github.com/Azure-Samples/ms-identity-python-samples-common/. I'm able to grab ID token claims from a request, but what I want to do is attach a listener to login to manipulate or add an entry in a database (regarding user information). I can't figure out a way to hook something to login. For reference, I created and am using a basic AAD tenant, and MS automatically redirects users after authentication to localhost/auth/redirect with some GET parameters like "code", "state", and "session state". -
django admin broken in development mode
I am a newbie in django (not in programming though) and following the w3school tutorials. When running the django admin at 127.0.0.1:8000/admin/ and in development mode, I end up with a layout problem which seems to be related to how the django css files are accessed. I have a clean and new django install. I have googled the problem and all that I have found are posts solving the same problem in production mode (not in development mode) or posts dated more than 10 years. Does anyone understand what is going on and how to fix the problem? -

How can I create a Django form out of a Model with an intermediary model? (I.E, a box with many products, as in, 10 products A, 5 products B)
First of all, the specifics of the project I'm working on are essentially the same as the example shown in this question, so I think it's easier to explain what I want to achieve using them. Background from the mentioned question: Think of a Box model that contains products, using an intermediary model, we can store not only multiple products but also different quantities of each product. Here is the code from the answer to the question mentioned above: class Box(models.Model): boxName = models.CharField(max_length=255, blank = False) product_set = models.ManyToManyField(ProductSet) def __str__(self): return self.boxName class ProductSet(models.Model): quantity = models.PositiveIntegerField() product = models.ForeignKey(Product, on_delete = models.PROTECT) class Product(models.Model): productName = models.CharField(max_length=200) productDescription = models.TextField(blank=True) productPrice = models.DecimalField(max_digits=9, decimal_places=0, default=0) class Meta: db_table = 'products' ordering = ['-productName'] def __str__(self): return self.productName This solution solves the model set up for what I want to achieve. In my specific case, the box model is a project model, and the products model is a materials model, essentially I want to store projects, which reference various materials required for said project, so each material will have different quantities. As a quick example: if there's a cake project, the materials can be 5 eggs and 1 … -
Django: update model via task
The code examples mentioned below are (over) simplified I have a users model with a field where all data related to each user from that model is recorded as xml. File -> users.py class Users(models.Model): firstname = models.CharField(max_length=200) dob = models.DateTimeField("date published") unconfirmed = models.BooleanField(blank=True, default=False) xml = models.TextField(blank=True, default="") I created a task in charge of updating that field for all users. At the end of the process, I trigger user.save() and it works fine. This task will be used on a regular basis to run a full update File -> update-users-xml.py Class Command(ParallelCommand): def handle(self, *args, **options): users = Users.objects.filter(unconfirmed__isnull=True) for user in users: # Get all fields user.xml = .... user.save() Now, what I'm trying to achieve is -> if an user is edited/created from the admin, the task is called and the xml column is updated. I edited the save function in the users model to trigger the task: def save(self, *args, **kwargs): async_task(call_command, "update-users-xml", self.id) And, as I anticipated, it wouldn't work because: Can't update because of lock key Maximum recursion depth exceeded Checking what options are available, using signal seems the way to go but I cannot make it work In the users model, … -
Why is 'Go Back' button not working in Django?
I am currently building an image description writing website. Tools/langs I use are html, css, django, and javascript. The problem is, when I click on the 'Go back' button on the html provided below, it doesn't redirect me to the previous mission-acting-writing page (account:write_page_url) but stays at the mission-acting-finish.html. 'Posting' and 'Image' are the models stored in models.py. 'Posting' stores every info user enters when writing one's post, and 'Image' stores individual image files extracted from the image zip file user has provided when writing the post.

How to edit a models (users) field ''globally'' using fetch or ajax?
So I have this JavaScript file and I want to globally change a field for the current authenticated user? I have a profile model with a level field: class Profile(models.Model): user = models.OneToOneField(User, null=True, on_delete=models.CASCADE) level = models.IntegerField(default=1) And for my url I have added the context and got it to log into the targeted JS file urls.py def game(request): profile = Profile.objects.get(user=request.user) #profile object level = profile.level #level context from the profile return render(request, 'games/game.html', {'level': level}) game.js: const data = document.currentScript.dataset; const level = parseInt(data.level); console.log(level); // BOILER PLATE FETCH // fetch(url, { method: "POST", credentials: "same-origin", headers: { "X-Requested-With": "XMLHttpRequest", "X-CSRFToken": getCookie("csrftoken"), }, body: JSON.stringify({payload: "data to send"}) }) .then(response => response.json()) .then(data => { console.log(data); }); and It console logs the level from that, However I want to know Is it possible to ''globally'' edit the level value using that boilerplate fetch down there? or maybe Ajax? My main issue is that I think I could specifically edit the level for the showProfilePage view (maybe) but I would prefer the level to be permanently updated to the desired number. That way it would retain its updated number anywhere I used its context. I just don't even … -
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) -
