Django inline formset missing_management_form error when deleting item

is virtual environment only for development or even for running application
I am using ubuntu 22.04 with python 3.10.6 version. My Django application currently works on python 3.7 version and it gives issues in 3.10 version.

How to get the date of last change from multiple Django models?
The environment is Django 4 and Python 3.10+. In the application there are multiple data models, each with 'created' and 'modified' DateTimeFields. I need to get the timestamp of last data modification - either creation of new object or modification of a existing one, for cache invalidation. Currently the code checks for the newest creation timestamp and is like this: from django.db.models import Max qs_1 = Model_1.objects.all() qs_2 = Model_2.objects.filter(active=True).order_by('created') qs_3 = Model_3.objects.filter(active=True).order_by('created') last = max(list((itertools.chain(list(queryset.aggregate(Max('created')).values()) for queryset in (qs_1, qs_2, qs_3) if queryset.count()))))[0] My questions are as follows: The expression to get the last creation date is quite convoluted. Is there a way to compute the latest timestamp over multiple models using the ORM alone? It can be done in pure SQL, so it should be possible in the ORM. How do I extend it to also compare the modified fields of the models? -

Django Forms two models with foreign key
I am trying to implement the booking function in my Django project. I have two models, one for the customer (Fordonsregister) and one for the service (FordonsService), a one to many relationship as one customer (ID is vehicle registration number: "regnr" which is the primary key in the customer model and the foreign key in the service model (code below). When a customer wants to book they click on a certain service (generated from the service types model (ServiceTypes, below) and get redirected by the urls.py to that specific service url. I would then like the customer to fill out only certain fields. The customer should only fill out the primary key, the foreign key in the form should be auto filled. the "typ" in the service model should be autto filled as the URL is different for the chosen service type. The models: from django.db import models # Create your models here. class Fordonsregister(models.Model): regnr = models.CharField(max_length=6, primary_key=True, null=False, blank=False) namn = models.CharField(max_length=255, null=True, blank=True) tel = models.CharField(max_length=255, default='070-000 00 00', null=True, blank=True) email = models.EmailField(null=True, blank=True) kund_sedan = models.DateTimeField(auto_now=True) kund_points = models.IntegerField(default=0) def __str__(self) -> str: return self.regnr class Meta: ordering = ['regnr'] verbose_name = 'Kunder' verbose_name_plural = … -

django.db.utils.OperationalError: no such column: users_classroom.class_code When attempting to Migrate
This is my first Django project, and I am attempting to add the attribute class_code to Classroom, and class_code is a random 6 character string that I plan to use to allow users to join a classroom using it.

changing the src of an image using javascript for a django website
I'm creating a website using django. At the front end I want to change slides every x seconds. My approach was to change the src of the image every x seconds using javascript Here's how I went about it: //Javascript function newSlide() { var imageTemplate = document.querySelector(".slide-img"); setInterval({ imageTemplate.setAttribute("src", "{% static 'images/newSlideImage.png' %}") }, x); } <!-- html --> <img class="slide-img" src="image.png"> I thought this would change the image for me but it didn't work at all.

Current path does not match path patterns error
I'm pretty new to Django and I've been following this page step-by-step: https://docs.djangoproject.com/en/4.1/intro/tutorial01/. However, when I try to call the polls app using localhost:8000/polls, a page not found error shows up. I don't have too much of an idea how to fix this, since I'm pretty new. I remember seeing how VS was complaining about the module admin not working but I resolved it by just reinstating the python interpreter. I also tried to re=run the server and reloading VS but it didn't really help. All of my modules match the one in the tutorial. -

Select using Django/Ajax
In the user profile page, there is a section for user to see the comments made on their posts. There is also a Select filter to query comments by Post. I am trying to use AJAX with the goal of avoiding page reload/refresh. Where am I going wrong? Since the page is still refreshing, I think I am missing some sort of div wrapper around my results. Besides that, the script probably needs more details.

How do you embed a webpack ReactJs bundle file in Django templates html file?

Django admin page - open 'VIEW SITE' in a new tab?
In admin portal of my Django app (v. 3.1), is it possible to configure the "VIEW SITE" link in the site header so that it will open in a new tab, target="blank"? I'm referring here to the link whose href can be configured via admin.site.site_url... I'd like to give my admin users quick and easy access to the site linked there, but I don't want them to be navigating away from their authenticated admin session. I currently have this value set to a custom configuration in urls.py like so protocol = 'https' domain = 'mysite.com' if os.environ.get('DJANGO_DEVELOPMENT'): protocol = 'http' domain = 'localhost:8080' admin.site.site_url = f'{protocol}://{domain}' as this URL actually needs to point at an application running on a different server. -
