Django - PDF file not uploading but path is available
I'm trying to upload a pdf file to the database with forms but however the file isn't send to the server. models.py class Presse(models.Model): pdf = models.FileField() forms.py class PresseForm(forms.ModelForm): class Meta: model = Presse fields = '__all__' I tried same way I do when uploading images, which works fine. Somewhere I have an error or forgot something I didn't know about. views.py def presse(request): article = Presse.objects.get(id=1) if request.method == 'POST': form = PresseForm(request.POST, request.FILES, instance=article) if form.is_valid(): form.save redirect('main:presse') else: form = PresseForm(instance=article) return render(request, 'main/presse.html', { 'article': article, 'form': form }) presse.html <form method="post" enctype="multipart/form-data"> {% csrf_token %} {{ form.as_p }} <button class="btn btn-success">Ersetzen & speichern</button> </form> If I upload a file after getting redirected I get error 404 GET http://localhost:8000/media/Untitled.pdf 404 (Not Found) The path is correct but the file wasn't served. Do you have an idea where the problem is? -

How to create a query across a M2M Relation with conditional aggregation in Django3?
I came up with this simple data model for a small quiz night. Now I want to create a queryset which contains the earned points (count if answer.is_correct is true) for each team and turn. Furthermore I want to show the earned points for each team in total. Unfortunately I dont get the annotate and values logic for Many2Many relations. class Team(models.Model): name = models.CharField(max_length=100) class Game(models.Model): attending_team = models.ManyToManyField(Team, blank=True) title = models.CharField(max_length=200) class Turn(models.Model): game = models.ForeignKey(Game, on_delete=models.CASCADE) title = models.CharField(max_length=200) class Question(models.Model): turn = models.ForeignKey(Turn, on_delete=models.CASCADE) question_text = models.CharField(max_length=500) class Answer(models.Model): question = models.ForeignKey(Question, on_delete=models.CASCADE) team = models.ForeignKey(Team, on_delete=models.CASCADE) is_correct = models.BooleanField(default=False) answer_text = models.CharField(max_length=500, blank=True, null=True) The leaderboard should look like the following table: Rank Team name Turn 1 Turn 2 Turn 3 Total 1 Team A 3 2 5 10 2 Team B 1 1 3 5 3 Team C 1 3 0 4 So I tried the following query in my view to display the total earned points per team: def leaderboard(request, game_id): game = Game.objects.get(id=game_id) turns = Turn.objects.filter(game=game) teams_turns = Team.objects.filter(game=game_id, answer__is_correct=True).annotate(num_correct_answers=Count('answer__id')) # example for total earned points of first team print(teams_turns[0].name, teams_turns[0].num_correct_answers) This works but I think it is not the best … -
Django Rest Framework - Could not resolve URL for hyperlinked relationship using view name "product-detail"
I'm struggling with DRF. When I try to obtain a list of products using: requests.get("http://127.0.0.1:8000/products/").json() Server error 500 occurs and an error is displayed as in the title: Could not resolve URL for hyperlinked relationship using view name "product-detail" However, when I try obtain a single product, request is successful: requests.get("http://127.0.0.1:8000/products/t/").json() {'id': 1, 'url': 'http://127.0.0.1:8000/products/t/', 'name': 't', 'slug': 't', 'description': '', 'order': 'http://127.0.0.1:8000/orders/1/', 'ingredients': '', 'allergens': '', 'suggested_products': [], 'image': None, 'available': True, 'price': 100.0, 'category': 'http://127.0.0.1:8000/categories/t/'} So what's the problem here?

The best way to connect Next.js CSR React app, Django and PostgreSQL
My question concerns programming a full-stack app. On the frontend, I have a Next.js React app. I want to render it on the client-side and probably use SWR. On the backend, I have a Django app with a PostgreSQL database. I have seen two approaches to make all of these work together. The first one is to use Django to serve Next.js React app with django-webpack-loader and then to load React app within Django template. The second one is to build two separate apps - frontend (Next.js) and backend (Django + PostgreSQL) and deploying them on two servers (e.g. Docker container). I have read this article and it makes me lean towards the second option. However, it is a pretty old solution and maybe some things have changed since then. What is the most optimal solution when it comes to connecting Next.js React Client-side rendered, Django and PostgreSQL? -
How to pass a Jinja variable inside a Svelte component (Django/Flask)
I have a Flask app, and I need to pass a variable called var to Svelte component App.Svelte In a HTML, I would do {{ var }} but this confuses Svelte as it uses { } for its delimiters, and says var is not defined. In Vue, we can define different delimiters for Jinja (such as []) to solve this problem, but in Svelte I could not find how to do it. How can I pass a variable to Svelte? -

Django How to return object.filter query results so I don't have to iterate through them
I am trying to return only one result from a query and return it as an object so I can call its' attributes in my template without having to iterate over them. Basically, I have a landing page that iterates a list of objects on table1 and creates a link for each one, like product listings. When I click on a link, it presents data from that object on the page. I want to also present data from the object on table2 that has the foreign key to the objects whose page I am currently on. The problem is I am returning an iterable item from table2, so in order to present that data, I have to run a for loop. It only returns one item, so it doesn't make a difference in how the page looks, but I would like to accomplish the same thing without the for loop. models.py class Exercises(models.Model): exercise = models.CharField(max_length=45) evolution = models.CharField(max_length=8) start_date = models.DateTimeField(blank=True, null=True) end_date = models.DateTimeField(blank=True, null=True) logo = models.TextField(blank=True, null=True) class Meta: constraints = [ models.UniqueConstraint( fields=['exercise', 'evolution'], name='exercise_evolution_UNIQUE') ] def __str__(self): return f"Exercise: {self.exercise}\t Evolution: {self.evolution}" class Units(models.Model): uic = models.CharField(max_length=10) unit_name = models.CharField(unique=True, max_length=45) mcc = models.CharField(max_length=5, … -
