Error while running the Django exe file created by PyInstaller
I am using Pyinstaller to convert my Django project to a standalone executable file. WHen i run the exe file, i get the following error in the window.

Django-filter Multiple Foreign Keys from one model
I have model with 2 fields place_of_loading and place_of_unloading with foreign key to the same model ConstructionSite. class DailyPerformance(models.Model): date = models.DateField() driver = models.ForeignKey(Employee, on_delete=models.CASCADE) TYPE_OF_GOODS_CHOICES = ( ("Excavated soil", "Excavated soil"), ("Sand", "Sand"), ("Crushed stone", "Crushed stone"),... ) type_of_goods = models.CharField(blank=True, null=True, max_length=30, choices=TYPE_OF_GOODS_CHOICES) place_of_loading = models.ForeignKey(ConstructionSite, on_delete=models.CASCADE, related_name='place_of_loading') place_of_unloading = models.ForeignKey(ConstructionSite, on_delete=models.CASCADE, related_name='place_of_unloading') number_of_rounds = models.IntegerField(blank=True, null=True) Now I want to implement filter using django-filters, but I want instead of 2 fields place_of_loading and place_of_unloading to have 1 field construction_site and to show results for both fields. So if I choose one construction site I want to get all information regarding loading and unloading materials. class DailyPerformanceFilter(django_filters.FilterSet): date = DateFilter(field_name='date', widget=DateInput(attrs={'type': 'date'})) start_date = DateFilter(field_name='date', lookup_expr='gte') end_date = DateFilter(field_name='date', lookup_expr='lte') place_of_loading = django_filters.ModelChoiceFilter(queryset = ConstructionSite.objects.all(), widget=forms.Select(attrs={'class': 'filter-select'})) place_of_unloading = django_filters.ModelChoiceFilter(queryset = ConstructionSite.objects.all(), widget=forms.Select(attrs={'class': 'filter-select'})) construction_site = django_filters.ModelChoiceFilter(queryset = ConstructionSite.objects.all(), widget=forms.Select(attrs={'class': 'filter-select'})) class Meta: model = DailyPerformance fields = '__all__' -
How to cache get_queryset() when using ForeignKeyWidget in django-import-export?
I am importing data using django-import-export but because I use ForeignKeyWidgets there are a lot of database calls making the import very slow for only a few 100 rows (checked with django-debug-toolbar). On the documentation page of Bulk imports the following is mentioned: "If you use ForeignKeyWidget then this can affect performance, because it reads from the database for each row. If this is an issue then create a subclass which caches get_queryset() results rather than reading for each invocation." I believe caching the get_queryset() results could help me, but I have no idea how to do the caching. Could you help me with some example code? I searched on Google for how to do this but didn't find any examples. -

Getting two "https://" in the url of image
I'm developing a project using Django and Django Rest Framework in which I have to save an image in a model. I'm using S3 bucket as a storage device. I'm able to upload the image and save it to the model. The Problem When getting response (either getting a single object or an array of objects), I'm getting the url of image with two https://. This only happens when I'm using the Django server that's hosted on AWS Ec2. The url of the image is returned normally when using localhost, the problem is with static files as well (but they aren't used, only the admin panel and rest-framework templates use it) Example: When calling the API from the hosted server This is the response.

Soft deletion in many-to-many relationships with through model in Django
I'm facing an issue in my Django project related to soft deletion in many-to-many relationships using a through model. I'd appreciate any help or advice on how to resolve this issue. I have three models in my application: Author, Book, and BookAuthor. The many-to-many relationship between Author and Book is defined through the BookAuthor model. Here are the definitions of my models: from django.db import models class Author(SoftDeleteModel): name = models.CharField(max_length=100) class Book(SoftDeleteModel): title = models.CharField(max_length=200) authors = models.ManyToManyField(Author, through='BookAuthor', related_name='books') class BookAuthor(SoftDeleteModel): book = models.ForeignKey(Book, on_delete=models.CASCADE) author = models.ForeignKey(Author, on_delete=models.CASCADE) class Meta: # Other necessary meta definitions pass The issue arises when I soft delete a relationship in the BookAuthor model and then try to access the books of an author using the query author.books.all(). Even though I have soft deleted the relationship in BookAuthor, I still see all the books associated with the author. I'm using the django-soft-delete package (https://pypi.org/project/django-soft-delete/), Does anyone have any suggestions on how I can address this issue and ensure that softly deleted relationships are not displayed when accessing through the many-to-many relationship? Any help or advice would be greatly appreciated! Thank you in advance! -

Send and receive socket without opening the html web page
I am having a django project where I have chat.html, journey.html, and manager.html. One of the flows is that I am sending socket for triggering journey from chat.html. And in the journey.html, I have a flow for approval where the socket gets sent to manager.html. This flow is working only when I keep all these 3 pages open in browser. But if I don't keep the "journey" page open in a browser, the socket is not getting received and send is not happening from "journey". This should work without the need to open "journey" page in the browser. How can I do that? -
Design patterns and user control in Django
I'm a new web developer building a system using Django for users across multiple departments to streamline data uploading, processing, and downloading. Most users will be restricted to uploading, modifying, and viewing data within their own department. Some privileged users will have additional download permissions for their department's data. Additionally, there will be super users who can view data from all departments. However, I'm stuck on implementing user permission control (effective translation depends on context, but "user permission control" works well here). I've considered two approaches: Multiple Web Pages: The simplest method would involve creating separate web pages for users with different permissions. Users with limited access would only see upload, modify, and view functionalities for their department's data, with no download button. Super users would have access to all functionalities and data across departments. While straightforward, this approach requires significant development time as separate pages need to be built for each permission level. Single Integrated Web Page: A more elegant but potentially complex solution would be to develop a single, comprehensive web page for all users. This page would have all functionalities, but user permissions would control what each user can actually see and interact with. This approach offers … -

Restrict Multiple Login for Same User with DRF

If user is logged in to browser_1 and user is logged in again on browser_2, then in that case, I want to log out of user_1 from browser_1. Here is models.py: class User(AbstractBaseUser, PermissionsMixin): '''User in the system.''' email = models.EmailField(max_length=255, unique=True) name = models.CharField(max_length=255) is_active = models.BooleanField(default=True) is_staff = models.BooleanField(default=False) objects = UserManager() USERNAME_FIELD = 'email' class UserSession(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) token = models.CharField(max_length=100) Here is views.py: from core.models import UserSession class CreateTokenView(ObtainAuthToken): '''Create a new auth token for user.''' serializer_class = AuthTokenSerializer renderer_classes = api_settings.DEFAULT_RENDERER_CLASSES def post(self, request, *args, **kwargs): response = super().post(request, *args, **kwargs) serializer = self.serializer_class(data=request.data) serializer.is_valid(raise_exception=True) user = serializer.validated_data['user'] UserSession.objects.filter(user=user).delete() token, _ = Token.objects.get_or_create(user=user) session = UserSession.objects.create(user=user, token=token.key) session.save() response.data['token'] = token.key return response Here I tried to make user create a new session and token when authenticated from browser_2, thus deleting the session in browser_1 and deactivating the token. But this didn't work.
