Generation of random numbers at no cost to the database
Hello everything is fine? I will build a raffle site and it needs to support several simultaneous people. For this, any optimization is welcome. Testing or verifying available numbers in the database can be a little damaging. As they are random numbers, I need to insert them with the certainty that they are not drawn to avoid repetitive queries. One solution would be to store the undrawn numbers in some complementary file and faster than a database and after adding the numbers, update the file and remove the used numbers. Thank you for your time and attention! :) -
Django Template is not displaying the table data
I am hoping someone can show me where I am going wrong. In one template I have a table that displays a few rows of data. I want a link in one of the fields to open a separate template for that field. The print commands display the correct information: print(vendor) displays: Sandpiper print(searchresult) displays: <QuerySet [<Vendor: Sandpiper>]> Sandpiper matches the name of the vendor in the vendor table, but when executed the detail page loads but does not display any of the data from the Vendors table. views.py def utilvendorview(request, vendor): searchresult = Vendor.objects.filter(search=vendor) print(vendor) print(searchresult) return render(request,'utilityrentals/vendors_detail.html',{"searchresult":searchresult}) urls.py path('utilvendorview/<vendor>/', views.utilvendorview, name='utilityvendor'), index.html (main template) <td><a href="utilvendorview/{{ results.Vendor }}">{{ results.Vendor }}</a></td> vendors_detail.html - Trying to have this populate {% extends "maintenance_base.html" %} {% load static from static %} {% block body %} <div class="album py-5 bg-light"> <div class="container"> <div class="row"> <div class="col-md-4"> <div class="card mb-4 box-shadow"> <div class="card-body"> <h5 class="card-title">{{ Vendor.company }}</h5> <h6 class="card-subtitle mb-2 text-muted">Email Address: {{ searchresult.email1 }} </h6> <h6 class="card-subtitle mb-2 text-muted">Email Address: {{ searchresult.email2 }} </h6> <h6 class="card-subtitle mb-2 text-muted">Phone: {{ searchresult.phone1 }} </h6> <h6 class="card-subtitle mb-2 text-muted">Mobile: {{ searchresult.phone2 }} </h6> <h6 class="card-subtitle mb-2 text-muted">Category: {{ searchresult.category }} </h6> <h6 class="card-subtitle mb-2 text-muted">Address1: {{ … -
Django customizable file path based off an user(Profile) name
thanks for any help in advanced. I am creating a personal website with Django, and I am coming from a Drupal background. I just started to learn the framework. I am looking help with... a suggestion for a package or direction on how to get started on how to create a customizable file (image, video) path based off an user(Profile) name. So, a new directory would be created, when the user(Profile) is created, and the media for that user is stored in their directory. Then it would also get broken down into, if its a image or video with their own directory. In theses files below, so far I have it setup like this. settings.py MEDIA_ROOT = os.path.join(BASE_DIR, 'media') MEDIA_URL = '/media/'`` users/models.py `class Profile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) image = models.ImageField(default='default.jpg', upload_to='profile_pics') def __str__(self): return f'{self.user.username} Profile'` Thanks. I am new to the Django framework, and was hoping for some direction to point me in the right direction. -

@login_required doesn't seem too recognize that I'm authenticated - django app
I'm a newbie python developer and I'm trying to develop a simple language school management app. I've created login page, which works and compares credentials to user's credentials provided in database. But even after succsessful authentication ('Success' is printed out in terminal) it seems that @login_required decorator doesn't see me as authenticated. What could be the reason? I'll provide all the data you need. Here's my simple views.py: from django.contrib.auth import authenticate, login, logout from django.shortcuts import render, redirect from django.contrib.auth.decorators import login_required def login_view(request): if request.method == "POST": username = request.POST.get("username") password = request.POST.get("password") user = authenticate(request, username=username, password=password) print(user) if user is not None: login(request, user) print('Success') return redirect("dashboard") else: error_message = "Invalid login credentials" return render(request, "login.html", {"error_message": error_message}) return render(request, "login.html") def logout_view(request): logout(request) return redirect("login") @login_required() def dashboard(request): return render(request, "dashboard.html") I used custom models and my custom authentication func looks like that: from django.contrib.auth.backends import ModelBackend from .models import Teacher class TeacherBackend(ModelBackend): def authenticate(self, request, username=None, password=None, **kwargs): try: teacher = Teacher.objects.get(username=username) except Teacher.DoesNotExist: return None if teacher.check_password(password): return teacher return None -

Issue with finding a rival in a Django web page
I am working on a Django web application that allows users to register teams, add players to those teams, and then find a rival team. However, I am experiencing an issue when users click the "Find Rival" button, as the system does not seem to find an appropriate rival team and leaves the user waiting. Here's an overview of the web page structure: The homepage (index.html) allows users to register a team by entering their details and location. In the create_players.html page, users can register players for the previously created team. After registering the players, users can click the "Find Rival" button to find a rival team. The issue seems to be related to the following code: The JavaScript function findRival() in the create_players.html template is responsible for finding a rival. When the "Find Rival" button is clicked, this function sends a POST request to the /find_rival/ route on the Django server. Potential causes of the issue include the findRival() function not sending the team data to the Django server correctly, the find_rival view on the Django server not properly processing the received data and/or not returning the rival information in the expected format, and the JavaScript code in the … -

Return fake dates for every blog post - bypass django's auto now
I am testing whether my blog posts are in reverse chronological order. To do so, I must set random dates for each post created. I'm using faker to set the dates. I am getting back a fake date, but it's the same date for every post. Is auto now still the issue here, or am I not using Faker correctly?

Django cookies not being saved in Safari nor Firefox
I recently started to test cookies in my development environment as I need it for token storage and csrf token. I came accross the issue of firefox and safari not setting the cookies in their storage tabs. If safari's 'prevent cross-site tracking' is off the behavior is the same with Firefox. However, not all users if any will have this setting off. With the previous mentioned, both browsers do not save the cookies in the storage tab. But, the cookies are received as when I click in an api testing button I have after loggin in, it works and the resources are accessed since cookies are sent. But, neither Safari nor Firefox show it in the cookies tab. Here is the response after log in. Response HTTP/1.1 200 OK Access-Control-Allow-Credentials: true Access-Control-Allow-Origin: https://localhost:3000 Access-Control-Expose-Headers: Content-Type, X-CSRFToken Allow: POST, OPTIONS Connection: close Content-Length: 714 Content-Type: application/json Cross-Origin-Opener-Policy: same-origin Date: Tue, 18 Apr 2023 17:11:05 GMT Referrer-Policy: same-origin Server: Werkzeug/2.2.3 Python/3.9.6 Set-Cookie: auth1=eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9; expires=Tue, 18 Apr 2023 17:21:05 GMT; HttpOnly; Max-Age=600; Path=/; SameSite=None; Secure Set-Cookie: csrftoken=Y1GzI80DfRc3lMkUnboTYeA3AZBY4aih; expires=Tue, 16 Apr 2024 17:11:05 GMT; Max-Age=31449600; Path=/; Secure Vary: Accept, Cookie, Origin X-Content-Type-Options: nosniff X-Frame-Options: DENY I am using Django and React both on localhost, … -
my elastic beanstalk application doesn't reflect the latest commit in the live environment
I am deploying my Django app via the eb CLI. I commit my changes to git and deploy (with eb deploy). In the past I would see my changes reflected after a deploy, now I do not. It is as if the application version is being cached on EB's side.Thanks in advance for any help. I checked the source on S3 and it is the latest version, so I have no idea why the live site (also accessed via eb open after deployment to be sure) doesn't reflect. I added some simple console logging to be certain, and it is missing. I've tried restarting the server and rebuilding the environment. Nothing has worked. I also deleted all previous application versions, so the only remaining one has the changes I want, then redeployed and restarted. Still not the version I want running on the environment. -
A form with fields that are associated with different database tables does not pass validation and does not create the necessary record in the db
I need to create an object in a database table using the form. This table is linked to other tables by means of a One-to-Many relationship. that is, through the ForeignKey. The fields are filled in by means of a drop-down list, which displays the objects that are in the tables associated with these fields. When I try to send data from the form, it does not pass validation and does not send anything. forms.py: class receiptForm(ModelForm): def __init__(self, *args, **kwargs): super().__init__(*args, **kwargs) self.fields['is_apartment'].empty_label = "Не выбрано" self.fields['is_owner'].empty_label = "Не выбрано" self.fields['is_receipt_type'].empty_label = "Не выбрано" class Meta: model = receipt fields = ['is_apartment', 'is_owner', 'is_receipt_type', 'date', 'receipt_file'] views.py: def create(request): error = '' if request.method == "POST": form = receiptForm(request.POST) if form.is_valid(): form.save() return redirect('main') else: error = "Форма была неверной" form = receiptForm() data = { 'form': form, 'error': error } if (request.GET.get('error')): return render(request, "main/main.html", context={'error': request.GET.get('error')}) return render(request, "main/main.html", data) models.py: class apartment(models.Model): address = models.TextField("Адрес квартиры", max_length=500, default="") def __str__(self): return self.address class owner(models.Model): surname = models.CharField("Фамилия", max_length=50, default="") name = models.CharField("Имя", max_length=50, default="") middle_name = models.CharField("Отчество", max_length=50, default="") email = models.EmailField("Email", max_length=254) def __str__(self): return f'{self.surname} {self.name} {self.middle_name}' class receipt_type(models.Model): pattern = models.FileField("Шаблон", upload_to='pattern') title … -
Testing a Consumer is failing when use database_sync_to_async Djagno Channels
So, I didn't use channels for a very long time, so let's be that this is a first time that I have tried to do something. I am trying to create 1 Consumer, wrapped with 1 custom Auth middleware and I want to test my Consumer, if it behaves properly in various test cases. Django==4.1.7 channels==4.0.0 middleware.py @database_sync_to_async def get_user(email): user = User.objects.get(email=email) if not user.is_active: raise AuthenticationFailed("User is inactive", code="user_inactive") return user class OktaASGIMiddleware(BaseMiddleware): def __init__(self, inner): super().__init__(inner) self.okta_auth = OKTAAuthentication() async def __call__(self, scope, receive, send): try: # token checking and retrieval claims = self.okta_auth.jwt_verifier.parse_token(token)[1] user = await get_user(claims["email"]) scope["user"] = user except Exception as exc: await send({"type": "websocket.close"}) raise return await self.inner(scope, receive, send) tests.py @aioresponses() async def test_connect_with_correct_token_edit_resource_draft( self, mocked_io_request ): mocked_io_request.get( # mocked request/respones ) communicator = WebsocketCommunicator( application, f"/ws/draft/1/?token={sometoken}" ) connected, subprotocol = await communicator.connect() self.assertTrue(connected) So, the issue is, when I use database_sync_to_async as Docs suggests, I am getting: django.db.utils.InterfaceError: connection already closed. When I use from asgiref.sync import sync_to_async, everything works fine and I can test my consumer properly. Also, i an attempt to avoid database_sync_to_async, I switched from JsonWebsocketConsumer to AsyncJsonWebsocketConsumer, but still no help. NOTE: Both of this code works … -

Incrementing an IntegerField in Django
I'm trying to implement the Polls app like the one in the Django documentation. I have an IntegerField to represent the number of votes an option has in my Polls app but if I try to add the voter to the list of voters and increment it by one in my views.py ever time a user votes, it adds to the user to the list of voters but the vote count doesn't increase. This is my Choice model... votes = models.IntegerField(default=0) voters = models.ManyToManyField(UserProfile, blank=True, related_name="my_votes") This is my vote function in views.py option.votes += 1 user = UserProfile.objects.get(user = request.user) option.voters.add(user) How do i fix this please? -
Django: while updating record: ValueError: Cannot force an update in save() with no primary key
There are similar issues on SO, but none alike this. I would like to update a field in a record of a m2m model which has a unique constraint on attendee + training. This model is defined as (model.py): class Occurrence(models.Model): attendee = models.ForeignKey(Attendee, on_delete=models.CASCADE) training = models.ForeignKey(Training, on_delete=models.CASCADE) attended_date = models.DateField(default=date(1900, 12, 31)) class Meta: constraints = [ models.UniqueConstraint(fields=['attendee', 'training'], name='unique_attendee_training') ] Now, consider e.g. that John has taken the Python course and already exists as record in the db. If I try get the date of when the training occurred, I would go like this: from trainings.models import Attendee, Training, Occurrence from datetime import date, datetime attendee = Attendee.objects.get(pk='john@gmail.com') training = Training.objects.get(pk='python310') occurrence = Occurrence.objects.get(attendee=attendee, training=training) print(occurrence.attended_date) # datetime.date(2021, 11, 4) However, if I try to update the date of this record, I get the error. occurrence = Occurrence(attendee=attendee, training=training, attended_date=date(2021, 11, 5)) occurrence.save(update_fields=["attendee", "training", "attended_date"]) The error being: ValueError: Cannot force an update in save() with no primary key. How do I update this record? Note I believe this should be enough to understand the question. But if you want to reproduce the whole issue, I post here the models (model.py) for Attendees and Trainings. class Attendee(models.Model): …
