Invalid password format or unknown hashing algorithm. Raw passwords are not stored. Django
I have a signup code views.py: def signup(req): if req.method == 'POST': form = SignupForm(req.POST) if form.is_valid(): form.save() return redirect('/') form = SignupForm() return render(req,'signup.html',{'form':form}) forms.py class SignupForm(forms.ModelForm): class Meta: model = User fields = ['username', 'email', 'password','first_name','last_name'] now whenever I try to login with this code the submission is successful but when I go to the admin panel and click on the user, on the password section it says Password: Invalid password format or unknown hashing algorithm. Raw passwords are not stored, so there is no way to see this user’s password, but you can change the password using http://localhost/admin/auth/user/3/password/. -
How do I make a serializer for many to many relationships in django if one model is a proxy model?
I have a project with multiple types of users: admins, drivers and commuters. I made proxy models for the drivers class User(AbstractBaseUser, PermissionsMixin): name = models.CharField(max_length=200) email = models.EmailField(unique=True, null=True) phone_number = models.CharField(max_length=15, unique=True) password = models.CharField(max_length=50) class Role(models.TextChoices): ADMIN = "ADMIN", 'Admin' COMMUTER = "COMMUTER", "Commuter" DRIVER = "DRIVER", 'Driver' base_role= Role.ADMIN role = models.CharField(max_length=50, choices=Role.choices) def save(self, *args, **kwargs): if not self.pk: self.role = self.base_role return super().save(*args, **kwargs) def __str__(self): return self.name I want to create a Vehicle model with a many to many relationship with only the drivers and also make serializers to allow me to link instances of drivers to vehicles and also list out all drivers and the vehicles they use. How do I go about this? -

Django annotate by first object from m2o or m2m field
I have 3 models: class Ban: name: models.CharField() person: models.ForeignKey(to="apps.Person") class Employee: name: models.Charfield() person: models.ForeignKey(to="apps.Person") class Person: name: models.Charfield() # here a have access to Ban and Employee as self.ban_set, self.employee_set I can get all Employee objects from Ban object as: ban_object.person.employee_set I need annotate Ban queryset by Employee first object from Ban "person.employee_set" field.

Django concurrency bug handling
I have an API written in Django that provides user with the list of files that they have. There is also a delete API that can delete a File that the user has. However, there is a bug where a GET request after a deletion still shows the previously deleted object. The GET API uses a filter query on the Files object. While the DELETE API will delete a given file id from the list, by getting and calling .delete(). After googling around, it seems like I need to wrap the database queries into a transaction.atomic block and perform select_for_update() in both of the APIs. Will this solve the issue? By right, if the GET Request is done after receiving the DELETE response it should not ever have this concurrency bug right ? It is only if we sent the requests concurrently. But, select_for_update is locking the database row right? So, will the GET API be able to still read the currently being deleted row? Is this the correct way of handling, or do I need to somehow change the isolation level of the database. Currently the DB is Postgresql which defaults to "Repeatable Read". After reading around, this is … -
Django PostgreSQL - Indexes on JsonField vs. custom fields
I am working on a booking system on Django with the following context: Users can create Items for others to book They can further specify the 'available time' per weekday (mon-sun), i.e. opening_time & closing_time. We can also expect that: A. most users adopt the same 'default' values across 7 weekdays (i.e. override when necessary), and B. most users adopt the same default values, say 8am-10pm. A search on Items by its availability, e.g. "Monday 3-4pm", will be expected and of considerably high traffic, so query performance is a must. I have a few options in mind but cannot decide which is better: Option A: Default values + JsonField + index from django.db import models from django.contrib.postgres.fields import JSONField class Item(models.Model): opening_time = models.TimeField() closing_time = models.TimeField() override = JsonField() class Meta: indexes = [ models.Index(models.F("override__sun_open"), name="override__sun_open"), models.Index(models.F("override__sun_close"), name="override__sun_close"), ... ] The Json will 'override' if necessary - might look something like {'sun_open': 07:00, 'sun_close': 23:00}. The filter() will be more complicated but can save on storage (given most users will use the defaults). Option B: JsonField + index class Item(models.Model): available = JsonField() class Meta: indexes = [ models.Index(models.F("available__sun_open"), name="available__sun_open"), models.Index(models.F("available__sun_close"), name="available__sun_close"), ... ] The query will be easy … -

Django On Delete IntegrityError
I get an integrity Error on deleting a Company. See this code below class Company(models.Model): name = models.CharField(max_length=500, null=True, db_index=True) code = models.CharField(max_length=50, null=True, db_index=True) fmp_code = models.CharField(max_length=50, null=True) stock_exchange = models.ForeignKey(Exchange, on_delete=models.CASCADE) exchange = models.CharField(max_length=50, null=True) class CalculationYearlyGrowth(models.Model): company = models.ForeignKey(Company, on_delete=models.CASCADE) date = models.DateField() current = models.BooleanField(default=False, db_index=True) historical_data = models.ForeignKey(CalculatedHistoricalFundamental, on_delete=models.CASCADE) This is the error I got django.db.utils.IntegrityError: update or delete on table "company_company" violates foreign key constraint "company_calculationy_company_id_c31e6552_fk_company_c" on table "company_calculationyearlygrowth" DETAIL: Key (id)=(308248) is still referenced from table "company_calculationyearlygrowth". So every time I want to delete a company and wherever it has foreign relations, I first have to delete CalculationYearlyGrowth of that company manually and I can't delete the Company. I have seen some other questions related to this but None have worked for me and the error itself is confusing since I have a Cascade delete so I don't expect the error to come. Thanks -
Django many-to-many fields and ModelForms
I am now working on a system that is calculating the CO2 emissions of a building. The thresholds are calculated taking into consideration the building type and the area of it. One building can have more building types and each building type has its area which in the end compose the gross area of the building (total area). What I am trying to do is when the user adds a building for calculation they will add the building information and for each building type the area of the it, the total area of the building is not important for now, but I am thinking on calculating it from the sum of the areas of the building types. Here is the models.py file: class BuildingType(models.Model): type = models.CharField(max_length=255, blank=True, null=True) co2_factor = models.DecimalField(max_digits=15, decimal_places=7, blank=True, null=True) class Building(models.Model): bbl = models.CharField(max_length=10, blank=True, null=True, unique=True) area = models.DecimalField(max_digits=10, decimal_places=2, blank=True, null=True) electricity = models.DecimalField(max_digits=10, decimal_places=2, blank=True, null=True) natural_gas = models.DecimalField(max_digits=10, decimal_places=2, blank=True, null=True) building_type = models.ManyToManyField(BuildingType, through='BuildingTypeSize', blank=True, null=True) class BuildingTypeSize(models.Model): building = models.ForeignKey(Building, on_delete=models.CASCADE) building_type = models.ForeignKey(BuildingType, on_delete=models.CASCADE) area = models.DecimalField(max_digits=10, decimal_places=2, blank=True, null=True) I am fairly new to Python and Django, i tried following some tutorials and also the documentation. … -

Expense Sharing api using DRF
I am creating an API which user can add expense in group. Imagine that we have 3 user in a group. User 1 add two expense with amount 90 and 210, and user 3 add an expense with amount 30. So basically when i see the group as User 1 i only should see Who do I owe and who owes me. it means i should see ( User2 owes you 100 and User3 owes you 90 ). first problem is i dont know how to calculate the 90 because user 3 had expense with amount 30 it means user3 owes user 1 100 but with the expense he paid, it will reduce his part from his balance. my main problem is in calculate settlements between 2 users amoung group. class GroupRetrieveView(generics.RetrieveAPIView): queryset = Group.objects.all() serializer_class = GroupSerializer permission_classes = [permissions.IsAuthenticated] def calculate_balance(self, pk): try: group = Group.objects.get(pk = pk) except group.DoesNotExists: return Response({'Error':'Group not found !'}, status=status.HTTP_404_NOT_FOUND) expenses = Expense.objects.filter(group = group) summary = defaultdict(Decimal) for expense in expenses: payer = expense.paid_by.username participants = expense.group.members.all() amount = Decimal(expense.amount) len_participants = participants.count() if len_participants > 0: # payment = amount - share share = amount / len_participants for participant in … -
ArrayField is empty even after serializer.save() (Django and Postgres)
I'm trying to save an existing Python list to an ArrayField in Postgres, but when saved it ends up empty. When I print data['questions'] and data['sources'], they both print a populated list (ex. [question1, question2, question3]), but when I print serializer.data, it shows as: 'sources': [] and 'questions': [] data['conversation']['bot'] works correctly. Hence, the problem might be in the model setup, but I'm unable to figure out what's wrong. I have run py manage.py runserver to migrate changes already but the lists are still empty. Here's the excerpt from views.py: def histories(request): if(request.method == 'POST'): data = JSONParser().parse(request) serializer = HistorySerializer(data=data) if(serializer.is_valid()): result = some_python_dictionary data['conversation']['bot'] = result['answer'] data['sources'] = result['sources'] data['questions'] = result['questions'] serializer.save() return JsonResponse(serializer.data, status=201) models.py from django.db import models import json from django.contrib.postgres.fields import ArrayField # Create your models here. class History(models.Model): conversation = models.JSONField() sources = ArrayField(models.CharField(max_length=256), default=list) questions = ArrayField(models.CharField(max_length=256),size=3, default=list) created_at = models.DateTimeField(auto_now_add=True) def __str__(self): return json.dumps(self.conversation) class Meta: verbose_name_plural = "Histories" serializers.py from rest_framework import routers, serializers, viewsets from .models import History class HistorySerializer(serializers.HyperlinkedModelSerializer): class Meta: model = History fields = ['conversation', 'sources', 'questions', 'created_at'] -

Integrating my Django REST API based extension into OpenedX container
I made a django extension according to these details:"Stand up an instance of Open edX using either the Dockerized Tutor release or our https://gallery.ecr.aws/ibleducation/ibl-edx-ce (architected using Tutor). Develop an extension that exposes a REST API endpoint and saves a greeting from the user (secure this endpoint with OAuth2 in the same way that Open edX secures its other API endpoints). This endpoint should do the following things with the user-submitted greeting: Log it (it should be visible in the platform’s LMS logs). Save it in the database (the greeting should be visible from the Django Admin). If the greeting is “hello”, then the view of this API endpoint should call the original greeting endpoint again with “goodbye” as the parameter. This is to make sure that you can write an Open edX view that can make an OAuth2-secured API call with a client ID, a client secret and an access token. Of course, if your code calls this endpoint with “hello” again then it’ll be recursive and things will crash." And now the steps where OpenedX is involed are left only please someone guide me through it. I created a docker container using the image link provided above now I … -

How to schedule tasks with Celery in Django based on a model field and update them dynamically?
I've encountered a challenge while developing an application with Django and using Celery to schedule tasks based on a model field. I'd like to share my solution and seek advice on potential improvements. As a relatively inexperienced developer, I welcome any guidance. I'm working on a Django application for managing training courses, and I need to schedule tasks when a registration deadline is reached.

I made an input field with quantity value and when i click 'add to cart' i want to send it to django view, but i get None type for some reason. Im using htmx for dynamic requests. views.py product = Product.objects.get(slug=slug) quantity = request.POST.get('quantity') print(quantity) productId = product.pid customer = request.user.customer product = Product.objects.get(pid=productId) order, created = Order.objects.get_or_create(customer=customer, complete=False) orderItem, created = OrderItem.objects.get_or_create(order=order, product=product) orderItem.quantity = quantity orderItem.save() if orderItem.quantity <= 0: orderItem.delete() html code <form method="post">{% csrf_token %} <div class="body-product__actions"> <div data-quantity class="body-product__quantity quantity"> <button data-quantity-minus type="button" class="quantity__button quantity__button_minus"></button> <div class="quantity__input"> <input data-quantity-value='True' autocomplete="off" type="text" name="quantity" value="1"> <!-- here is the input im trying to get --> </div> <button data-quantity-plus type="button" class="quantity__button quantity__button_plus"></button> </div> <button data-ripple type="submit" hx-get="{% url 'Add product page' product.slug %}" hx-trigger="click" class="body-product__add-to-cart button button_cart"><span class="_icon-cart-plus">Add to cart</span></button> <!-- This is the button that sends the htmx request --> <a href="#" class="body-product__cicil border-button border-button_cicil"> <img src="{% static 'mstore/img/icons/cicil.svg' %}" alt="cicil"> </a> </div> </form> I tried to get the value with post, get requests but the result is similar, i have similar code in my other project and it works perfect.
