Best solution to integrate independent applications into a Django (& React) platform?
I have a general platform that I want to evolve. The platform is hosted on a domain like "https://www.example.com". For certain specific users, I would like to give them access to a completely independent application (several applications, independent platform) from their profile on a subdomain like "https://subdomain.example.com". I would like these applications to have: Their own database Be accessible only for authenticated and authorized users Their own server The Django project of the general platform is written in Django/React. Before launching this project, I am wondering about the best way to integrate these independent applications into the main platform. I have done some research and manipulation, but I don't know how to decide on the project architecture: django-host, django-tenant, django-site ... Below is my current architecture What is the best possible option to connect other independent applications to the general platform with the current users? -
Django ignores timezone settings
I am trying to create a record in my Django project with the timezone set to Europe/Rome. When I create the model object, I use this function to set the timezone: MyModel.objects.create( name="trial", date=datetime_aware("2023-08-15") ) However, I am encountering an issue where the record is being stored with the date "2023-08-14" and the UTC timezone (GMT), despite my efforts to set it to Europe/Rome. In order to do this, I first set the following values in my settings.py file: USE_TZ = True TIME_ZONE = "Europe/Rome" Next, I wrote a function to create a datetime object with the appropriate timezone: def datetime_aware(dt_string, timezone=settings.TIME_ZONE): if dt_string: dt = datetime.datetime.strptime(dt_string, "%Y-%m-%d") dt_aware = make_aware(dt, pytz.timezone(timezone)) return dt_aware return None Can you help me figure out what's going wrong? -
How to make the updated_by field display the user's full name in Django?
I just recently started using Django. Please help me figure it out. I have a database that stores various information about network devices. On the site, this information is displayed in a table. I want the updated_by field to display the full name of the user who created this table or who last modified it. All users are registered in Django, there are fields: first name, last name. I want these two fields to be displayed together in the table in the updated_by field. For example, at the end of the table on the site it was written: Updated by an employee: Ivanov Ivan. I tried to do this: from django.contrib.auth.models import User updated_by = models.ForeignKey(User, verbose_name='Updated by an employee', on_delete=models.SET_DEFAULT, default='Employee deleted') But I am getting an error OperationalError at /admin/mainapp/device/1/change/ no such column: device.updated_by_id -

Aggrgate JSON key value of JSONField Django PostgreSQL
I have a simple model setup as below, import random import string from django.db import models def random_default(): random_str = "".join(random.choice(string.ascii_uppercase + string.digits) for _ in range(10)) return {"random": random_str, "total_price": random.randint(1, 100)} class Foo(models.Model): cart = models.JSONField(default=random_default) I want to get the sum of total_price from all Foo instances. In native Python, I can do something like below to get the sum, but I believe it is suboptimal. sum(foo.cart["total_price"] for foo in Foo.objects.all()) I tried the following aggregate queries with Django, but none seems correct/working. 1. Foo.objects.aggregate(total=models.Sum(Cast('cart__total_price', output_field=models.IntegerField()))) # Error # django.db.utils.DataError: cannot cast jsonb object to type integer 2. Foo.objects.aggregate(total=models.Sum('cart__total_price', output_field=models.IntegerField())) # Error # django.db.utils.ProgrammingError: function sum(jsonb) does not exist # LINE 1: SELECT SUM("core_foo"."cart") AS "total" FROM "core_foo" ^ # HINT: No function matches the given name and argument types. You might need to add explicit type casts. Question What is the proper/best way to get the sum of top-level JSON keys of a JSONField? Versions Python 3.8 Django 3.1.X -

How to get rid of daylight saving time (DST) in Django? (Because in my country it's not being used anymore!)
In my country, daylight saving time (DST) is not being applied anymore, but Django is still taking it into account.

Django Mock isn't working as expected in Unit test
I'm having a view in which there is a method called can_upload_file that makes external calls. So, in my unit test I tried to mock that particular method as follows: DatasetViewSet._can_upload_file = MagicMock() DatasetViewSet._can_upload_file = "valid" response = self.client.post(self.url, self.dataset, format="multipart") However I see that the actual can_upload_file method in the view is still executed. How can I fix this? -

Which one do you prefer, django vs fast-api?
I got a question. I'm studying Python and Django. However, I heard that the fast-api is now a trend, so I am wondering whether to study Django(django rest framework) more or to study the fast-api again. Which framework do you prefer in practice? If you develop with Python, I would like to know the answer to whether you use django(django rest framework) more or fast-api more in the actual field. I'm wondering which one to prioritize. -
Django Login dont work, how i can i fix it?
I have a functional login feature on my website, but unfortunately, the private page can still be accessed by typing in its URL, even without logging in. I am concerned about this security flaw and would like to know how I can prevent users from accessing the private page without first logging in.

Django how to update querysets' jsonfield based on current value

I can't add a 1st empty option in my select
I have the following form class Report3Form(Form): fecha = ChoiceField( choices = [], widget=Select(attrs={ 'class': 'form-control', }), ) def __init__(self, *args, **kwargs): super().__init__(*args, **kwargs) self.fields['fecha'].choices = [(f"{d:%Y-%m}", f"{d:%B, %Y}") for d in ConsumoElect.objects.dates("fecha", "month")] That is based on this model: class ConsumoElect(models.Model): pgd = models.ForeignKey(TipoPGD, on_delete=models.CASCADE, related_name='consumoelect') fecha = models.DateField(default=datetime.now) fecha_AM = models.CharField(max_length=20) lec_madrugada = models.IntegerField(default=0) lec_dia = models.IntegerField(default=0) lec_pico = models.IntegerField(default=0) reactivo = models.IntegerField(default=0) dato = models.IntegerField(default=0) total = models.IntegerField(default=0) The form shows a select with the month and its year as if a distinct was used in the ORM, I need the first thing that the select shows to be an empty value that says "select a date". This link shows an example of what I want, but I can't adapt it to my problem In Django how to add a placeholder to a form based on model charfield
