not triggering the post_delete_signal when it's coming from a CASCADE delete
Hello I have two django models linked by a foreign key and it looks like this class Author(models.Model): id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False) name = models.CharField(max_length=255, null=False, db_index=True) number_of_books=models.IntegerField() #other fields class Book(models.Model): author = models.ForeignKey('Author', on_delete=models.CASCADE, related_name='books') name = models.CharField(max_length=255, null=False, db_index=True) #other fields The Book model has a post_delete_signal that triggers some computations for te author instance def book_post_delete(sender, instance, **kwargs): # Re save max exposure author = instance.author author.number_of_books = author.books.count() author.save() trigger_computation(author) My problem is that if I delete an author for example, then his books are also deleted because of the on_delete=models.CASCADE, the book_post_delete function is then called and the trigger_computation(author) is called, which takes a lot of time for me and is also useless because the author is being deleted. Is there a way to get around not triggering the computation when the instance that is being deleted is an author? -

How to create group of users in django
I want to create group where members of the group can see the documents, announcements and also list of members of the group. How do I code that in django models? Do I create custom group? Users can be member of many groups, and group can have a lot of members. So, it should be a many-to-many relationship(?) Do I put users under group models or the other way around? And how do I store announcements and documents of the group? Do I keep it under group models too? Or put group under the announcements and documents model, like how category is put under the post models like this: class Category(models.Model): name = models.CharField(max_length=100) class Post(models.Model): category = models.ForeignKey( Category, on_delete=models.PROTECT, default=1) title = models.CharField(max_length=250) content = models.TextField() -
Redering a list of objects with date and drop down
I am on the path of learning django. My personal project aims to create a clickable date based on available dates for different destinations. I have some data that is directly scraped from scrapy in the following format: departureDate = [{'departureDate': '2022-07-29', 'id': 'The Bahamas'}, {'departureDate': '2022-11-11', 'id': 'The Bahamas'}, {'departureDate': '2022-11-18', 'id': 'The Bahamas'}, {'departureDate': '2022-12-02', 'id': 'The Bahamas'}, {'departureDate': '2023-01-13', 'id': 'The Baltic Sea'}, {'departureDate': '2023-02-03', 'id': 'The Baltic Sea'}, {'departureDate': '2023-02-17', 'id': 'The Baltic Sea'}, {'departureDate': '2023-03-03', 'id': 'The Baltic Sea'}, {'departureDate': '2023-03-24', 'id': 'The Baltic Sea'}, {'departureDate': '2023-04-07', 'id': 'The Western Mediterranean'}, {'departureDate': '2023-04-14', 'id': 'The Western Mediterranean'}, {'departureDate': '2023-04-28', 'id': 'The Western Mediterranean'}, {'departureDate': '2023-12-21', 'id': 'The Western Mediterranean'}, {'departureDate': '2023-12-28', 'id': 'The Western Mediterranean'}], I want to then be able to load this into my model: Here's my model.py: from django.db import models class Cruises(models.Model): departureDate = models.DateTimeField('Departure Date') id = models.CharField('Destination', max_length=200) Then my views: from django.shortcuts import render from .models import Cruises def basic(request): departure_list = Cruises.objects.values('departureDate', 'id') return render(request, cruise_control/basic.html, context={'departure_list':departure_list}) basic.html: <!DOCTYPE html> <html> <head> <meta charset="utf-8"> <title>Cruises</title> </head> <body> <h1> Cruise Control </h1> {% for dep_l in departure_list %} <form action="/action_page.php"> <label for='destination'>Destination</label> <input type="text" list="destination" /> <datalist id="destination"> … -

I built a simple signup form that will take data as the user will click submit it and will save it in the database. But for some reason, I am able to validate it.

Django rest_framework, logout redirect doesnt work
I am trying to redirect to the home page after clicking on Logout urls.py urlpatterns = [ . . path("api-auth/", include("rest_framework.urls")), ] settigs.py . . LOGOUT_REDIRECT_URL = "/" ACCOUNT_LOGOUT_REDIRECT_URL = "/" The problem is it still redirect to /api-auth/logout/?next=/current-page. This will cause an error because this "current page" needs authentication (requires a login) unlike the home page which doesn't require a login I also tried path("api-auth/logout", RedirectView.as_view(url="/", permanent=True)) but this again didn't work(still redirected to the "current page"). How can I redirect to the home page? -
Telethon TelegramClient.sign_in deadlock

Thus, first a user enters his phone number, password, and then, when he receives an SMS with a code, he enters it too, and I can work with TelegramClient.

Django. Updating the model instance

The issue is I don't know how to save value to my model's field "total_price". I thought accessing self will do that, but it doesn't. The method computes the value however field isn't updated. -

Best way to use "context" on Django templates for many variables / dictionaries
I want to send a lot of data to 1 Django template (to show it on 1 specific page). The data comes from 2 sources: At least 1 list, with many dictionaries inside (I can't change any of this, it comes from Google Ads API). Many variables (I can change them, for example, to turn them into dictionaries or tuples if necessary). The variables are very simple, something like "variable = other_variable / 100" (just 1 value, no need for a key), so I don't need the variables to be turned into a dictionary. But I've understood (maybe wrong) that the "context" from Django's render needs dictionaries. The variables' data comes from the list (I do some calculations using some of the list values), but maybe this is not relevant for my question. Right now I'm doing something like this in my views.py: campaign_data = [] CODE TO FILL THAT LIST WITH API DATA (MANY DICTIONARIES INSIDE) clicks = sum(data['campaign_clicks'] for data in campaign_data) sum_clicks = {"sum_clicks" : clicks} context = { 'campaign_data' : campaign_data, 'sum_clicks' : sum_clicks } return render(request, 'testing.html', context) And then on the Django template I use the data from views.py like this: {% for element … -
Wierd behaviour in django
I am using SQLite in my Django project, I am gathering the data into the database manually with python. everything worked fine in that phase, now when I am trying to reach them in the templates file, something weird is happening, Django keeps giving me a NoReverseMatch match (because I am having a link that is referring to a view for some calculations, this view needs a URL which I have in my template), the weird thing is, when I open my 127.0.0.1:8000/admin and opening the data I've gathered and saved them, Django won't give me an error! it seems I have to do something like migrating my new data manually to project too, its very confusing -

Custom links in django

(I want the link to be made automatically as the instance of article class is created, and without user) I can just make it a CharField and then replace whatever was there with the function, but that just seems like a sloppy solution, also it'll give a usless field to the default admin-panel. -
