django if any of many to many has filed with value of False
Say I have a model of a library and I want to hide some books if either the book is marked as hidden or any of authors is marked as hidden or any of categories is marked as hidden. class Category(CustomModel): name = models.CharField(max_length=32, unique=True, null=False, blank=False) ... is_hidden = models.BooleanField(default=False) class Person(CustomModel): first_name = models.CharField(max_length=64, null=False, blank=False) ... is_hidden = models.BooleanField(default=False) class Book(CustomModel): title = models.CharField(max_length=128, null=False, blank=False) authors = models.ManyToManyField(Person, null=False, blank=False) translators = models.ManyToManyField(Person, null=True, blank=True) ... categories = models.ManyToManyField(Category, null=False, blank=False) ... is_hidden = models.BooleanField(default=False) Now I tried these queries to exclude all books with either, is_hidden=True, authors__is_hidden=True, translators__is_hidden=True, or categories__is_hidden=True: as this: books = Book.objects.filter( is_hidden=False, authors__is_hidden=False, translators__is_hidden=False, categories__is_hidden=False).distinct() and this: books = Book.objects.filter( is_hidden=False, authors__is_hidden__in=[False], translators__is_hidden__in=[False], categories__is_hidden__in=[False]).distinct() but I cannot find a way to achieve it. I wish to achieve my goal without a loop since the number of entries can get as high as 80K. How to make the query? -

Infinite Load Page Phenomenon in Django Virtual Environments
I'm using MAC, and I had a problem developing django using virtual environments. My development environment uses vscode to access the aws server, open the django virtual environment with 127.0.0.1:8000, and test the page using local(Mac) chrome. I didn't have any particular issues before, but recently, page loading has suddenly slowed down and the page loading bar is running at infinity. I changed the operating system to Windows and tried again, but there was no problem. The issue only happens on my MacBook. What should I do? I emptied my MacBook's Chrome cache and reinstalled Chrome, but nothing improved. I was wondering if it was a vscode problem, but my development environment is being developed using aws server, so it means that it is not a vscode problem to operate smoothly in Windows environment. -

Problem in creating folder and file after upload in Django
I'm creating a source code evaluater platform using React and Django. Basically an user is going to upload a source file of his choice, my frontend sends the file to backend, which is working fine, and my backend has to create a copy of the file in a specific folder structure, because the code evaluater (different application) is set to access this structure searching for new files. The folder structure is basically like this: I've a first folder name Delivereds, inside it I've many folders named by the user id, inside each of these folders I've many folders named by the submission id. To simplify this problem solving, let's deal with this ignoring user id, let's just focus on folder adress like this: "/Delivereds/Question1/code.c++". My problem is that when I try to create a folder, it doesn't work. I'm pretty much a beginner in Django, so I don't really know if I need to set some configs in the main settings file. The solutions that I found in my searches are really simple and didn't work in my case. My current code is like this: elif request.method == 'POST': if request.FILES.get('file'): file = request.FILES['file'] parent_dir = '..\Delivereds\Question1' path = os.path.join(parent_dir, … -
Better way to connect django model with django cms page/placeholder
I'm making a website, and one of the features - News. I have a model News with some fields, to have a better user experience i thought that i need some more information for every News - html snippet and for good administrating that additional content for News, i decided that i need to use django csm. So on every page i have an information from News model and in the end of that - html snippet made with cms. And there is a problem - i don't know the better way to make my wishes. Important bit: i want to make all connections with model slug. I read docs about apphooks - but maybe it's not a good approach in my case? Couse apphooks make application embedding to django cms, but i need only the piece of creation and connecting of html template made by this cms. Additionally i tried just take a Page made by cms and put it in my html, but it was something wrong there, maybe it is not possible? Maybe i can see pages only on cms urls? page = Page.objects.all()[0] # for example in views I tried to make the model placeholder, but … -

Converting Flask or Django Web App to Desktop App for Secure Distribution
I have developed a web application using Flask/Django, and now I'm interested in converting it into a desktop application. I want users to be able to run the application directly from their desktop without needing a web browser, and I'm particularly interested in distributing it securely without exposing the source code. Can someone guide me on how to achieve this conversion? Are there any tools or frameworks available that can help in this process? I'm aiming to preserve the functionality and user experience of my web application while making it suitable for desktop usage and secure distribution. Additionally, I would appreciate any insights or best practices from those who have successfully converted web apps to desktop apps before and managed to distribute them securely without exposing the source code. Thank you in advance for your help! -
JWT refresh token is in httponly cookie, How to use DRF simple-jwt to regen the token
I have a front and backend app, front is react and backend is python Django (DRF), so my problem is I store the refresh token inside an HttpOnly cookie and send it in every request, but the DRF endpoint for refresh token (rest_framework_simplejwt.views.TokenRefreshView) will read the token itself from request.data which is the body of the Http request, is there a better way to handle this view other than rewriting a custom view? -
Django/ Office 365 : 535, b"5.7.139 Authentication unsuccessful, user is locked by your organization's security defaults policy
Running into the following error when trying to send email with Django: 535, b"5.7.139 Authentication unsuccessful, user is locked by your organization's security defaults policy. Here is my current config: #Emailing Settings EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend' EMAIL_HOST = 'smtp.office365.com' EMAIL_FROM = 'email@email.com' EMAIL_HOST_USER = 'email@email.com' EMAIL_HOST_PASSWORD = 'password' EMAIL_PORT = 587 EMAIL_USE_TLS= True This error was raised here: https://learn.microsoft.com/en-us/answers/questions/1469524/error-when-testing-smtp-for-django-website The irony of the answer provided by Microsoft is to suggest to disable the security default and also adding "not recommend". It seems the error is specific to Microsoft and comes from the use of SMTP, which MS's security doesnt like and encourage the use of OAuth. Can someone suggest an approach that worked for them? Did you disable the security defaults (for the specific email): is it risky? Did you implement OAuth and if so what steps did you take? -

jQuery loading animation not showing

Is this proper way to handle all CRUD operations in a single view (endpoint) using HTMX?
I'm new to using HTMX with Django and I'm seeking guidance. I'm in the process of redesigning a large CRUD application, aiming to integrate HTMX for improved interactions. Given the complexity of the app and its interactions with the database across various models, I want to ensure I start off on the right foot by adopting HTMX best practices early on. I've seen in many tutorials that everyone follows the common practice of creating separate views and URL paths for each database transaction (such as create, edit, delete, update).
