Django. How to save serialized and validated data?
I have a Car model with name, model and serial number fields. In which the combination of the name and model fields must be unique. I am using serializers.ModelSerializer from rest_framework and validator UniqueTogetherValidator. validators = [ UniqueTogetherValidator( queryset=models.Car.objects.all(), fields=['name', 'model'] ) ] The database already has an entry {'name': 'one', 'model': '13', 'serial number': 99}. I want to add a list of cars: data = [{'name': 'one', 'model': '13', 'serial number': 99}, {'name': 'two', 'model': '3', 'serial number ': 98}, {' name ':' three ',' model ':' 1 ',' serial number ': 949}] For this I use: serializer = CarSerializer (data = data) if serializer.is_valid (): serializer.save () I understand that is_valid () will return False. In the passed list, only one record is not valid, how to save valid data from the passed list? -
django "<User: user556>" needs to have a value for field "id" before this many-to-many relationship can be used
I'm trying to save a M2M object ( set it to a default value which is the one with id = 1 ). The problem I'm getting the following error: "<User: user556>" needs to have a value for field "id" before this many-to-many relationship can be used. I looked at previous feeds that covered the same error but no one explained when it happens in the form_valid function as it happened to me My code is as follows : def form_valid(self,form): instance = form.instance instance.groups.set(1) instance.save() return super(UserCreateView,self).form_valid(form) -
Simplest way to lock the model instances and its related object in Django
To avoid the concurrency I am trying to put a lock on Django's model's instances. Orders class Orders(BaseModel): created_by = models.ForeignKey(User, on_delete=models.PROTECT, null=False, blank=False) property = models.ForeignKey(Properties, on_delete=models.PROTECT, null=False, blank=False) units = models.IntegerField(null=False, blank=False) buy_price_per_unit = models.FloatField(null=True, blank=True) sell_price_per_unit = models.FloatField(null=True, blank=True) order_type = models.ForeignKey(OrderType, on_delete=models.PROTECT, null=False, blank=False) order_status = models.ForeignKey(OrderStatus, on_delete=models.PROTECT, null=False, blank=False) fluctuation_upper_limit = models.FloatField( null=False, blank=False) #IN PERCENT fluctuation_lower_limit = models.FloatField( null=False, blank=False) #IN PERCENT order_trade_fee = models.FloatField( null=False, blank=False) #IN PERCENT tax_percent = models.FloatField( null=False, blank=False) #IN PERCEN In the above model I have a ForeignKey field property referencing to the model Properties. Furthermore, I also have a model PropertyOwners which has a ForeignKey field property referencing to the model Properties. The query I am using is - Orders.objects .select_for_update() .exclude(created_by=created_by) .values('id', 'property', 'units', 'created_by', 'sell_price_per_unit', 'order_status') .filter(property=order_obj.property, order_type__name=SELL, order_status__in=[PARTIALLY_COMPLETED[1], OPEN[1]], sell_price_per_unit__lte=order_price) .order_by('sell_price_per_unit') You can see I have used select_for_update() to lock the Orders instances fetched by this query. However, I also want to lock the instance of model Properties to which all these order are pointing and the instances of the PropertyOwners where the field property and created_by from Orders is equal to the fields property and owner from PropertyOwners for each order. The query … -
Integrating Django Rest Framework with OneLogin
I am working on a backend built on Django and Django Rest Framework. I have been trying to integrate with Onelogin for a little bit and I do not manage to do it. SAML: It seems that python3-saml is mainly build for traditional Django using sessions. Which is not a very REST like behavior. I could not find a way to make it work with DRF. Nor could I find a package that fits my needs. I will continue working on OpenId connect but I am wondering if it is possible to use Django Rest Framework with python3-saml? Thank you for you help -

Saving cookies via Python HTTP class
I have an extrenal authentication web application which isn't a part of my base web app. I would like to save auth token after succesfully login process into my main app. The only one available method is using BE for that.

Is using BE to save a cookies by HTTP class is safe? Is there any chance to malform/compromise that process from outside? -
Django Rest Framework: Multiple branches of API w/ varying queryset/permissions
In my Django-Rest-Framework application, I have the need to divide the API into two branches such as: /api/public/... /api/private/... Consider a model Analysis like so: from django.db import models from django.conf import settings class Analysis(models.Model): user = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE) public = models.BooleanField(default=True) What I want then is: /api/public/analysis => filter queryset with Q(public=True) /api/private/analysis => filter queryset with Q(user=request.user) | Q(public=False) Similar pattern is required in 5+ models. I have thought of 2 half-baked solutions: 1. AbstractViewSet sub-classed into PublicViewSet and PrivateViewSet class AbstractAnalysisViewSet(viewsets.ReadOnlyModelViewSet): queryset = Analysis.objects.all() serializer_class = AnalysisSerializer ordering = [ "-created_at", ] permission_classes = [IsAuthenticated,] class PrivateAnalysisViewSet(AbstractAnalysisViewSet): def get_permissions(self): permissions = super(PrivateAnalysisViewSet, self).get_permissions() if self.action in ["retrieve"]: permissions.append(HasObjectPermission()) return permissions def get_queryset(self): queryset = super(PrivateAnalysisViewSet, self).get_queryset() if self.action in ["list"]: auth_user = self.request.user query = Q(user=auth_user) | Q(public=False) queryset = queryset.filter(query) return queryset class PublicAnalysisViewSet(AbstractAnalysisViewSet): def get_permissions(self): permissions = super(PublicAnalysisViewSet, self).get_permissions() if self.action in ["retrieve"]: permissions.append(IsPublicObjectPermission()) return permissions def get_queryset(self): queryset = super(PublicAnalysisViewSet, self).get_queryset() if self.action in ["list"]: query = Q(public=True) queryset = queryset.filter(query) return queryset This would work but I don't really want to duplicate views into multiple classes like that because then I also need to register multiple viewsets with the DRF router.

Django - automate CRUD from models (DRY approach)?
I am new to Django but not to developing. I need to make an application in which user can do CRUD operations (Create, Read, Update, Delete). This functionality should apply to all models and the fields for Create & Update will be auto-generated from model attributes. What I describe is pretty much the functionality that comes with the Admin page. However, I want to use it in my own app instead of using the Admin app. For example, let's suppose we have Author and Book models: (models.py) from django.db import models class Author(models.Model): first_name = models.CharField(max_length=60) last_name = models.CharField(max_length=60) def __str__(self): return self.last_name class Book(models.Model): title = models.CharField(max_length=60) author = models.ForeignKey(Author, on_delete=models.CASCADE) def __str__(self): return self.title I suppose that the above information (models) could be enough for CRUD operations, without repeating code of the same logic for each model. I am aiming at a functionality like in admin page where all you have to do is register your model. I am aware of ModelForm and Generic Views but while they help avoiding hard-coding form fields, I have not found a non-repetitive coding approach. I would like to avoid approaches like the following where same code is being duplicated for each … -

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? -
