Create superuser in ktor
in django, there's manage.py createsuperuser for creating a user with elevated privileges. For ktor, I have resorted to creating a user programmatically when the app starts, (first checking if the user already exist) Is there a more elegant or standard way of doing this? I assume it would be a similar process in other frameworks, express, flask etc since they don't also have that -

How to filter a queryset by a many2many field
I have a Notification model which has a field called seen_users like so: from django.contrib.auth import get_user_model User = get_user_model() class Notification(models.Model): title = models.CharField(max_length=255) seen_users = models.ManyToManyField(User, blank=True) Whenever a user sees a notification (.e.g notification_obj), that user will be added to notification_obj.seen_users.

Why celery doesn't run the code and how can i fix it?

Django: Ignore trans strings which are already translated in app directory
I use django-allauth as a third partie package in my Django project. I copied some templates from django-allauth into my template directory to modify the layout. But I did not touch the translation strings! After running makemessages this strings appears in my .po file even though it is translated in the app directory for django-allauth. (To manage my translations I use Weblate.) How can I stop this behavior? This is blowing up my .po file and is confusing the translators, because we have to notify them not to touch this string. Can I create a list of "msgid" which will ignore some strings? -
Django Admin Soft Dashboard in aws ec2 ubuntu 24.04 using pyhton 3.6.8
For my django admin panel I used django-soft-admin-panel pip for UI, as my python runtime is 3.8 it didn't run, so I downgraded by python to 3.6 and developed the project, the ui and all other things are perfectly working in local. I need to deploy the project in any of the aws services. At first I used lambda, but lambda is only for runtime >= 3.8 then I used Elastic Beanstalk, ebs is only for runtime >= 3.7 then I deployed in EC2 with nginx and gunicorn but the project and server getting crashed. Is there any solution? -

Issue with closing modals by clicking outside on specific page

The fact is that I have no experience at all and I use a tutorial from the Internet.

Deployment: Procfile with Django Project Structure for more than one App
I need to know how you normally solve this issue. When you start a project, django creates a folder for the project and a second one inside it with the exact same name and the files like: settings.py, init.py, wsgi.py, etc. After Im done with the repo I delete one of the two folders with the same name in order to let Procfile find project.settings inside the wsgi.py. I want to be able to run the Procfile considering the original structure, because I want to learn how to create more than one app inside a project. My exact question is. How should I setup my procfile? right now is like this: web: gunicorn expenses.wsgi --log-file - But Then Procfile doesn't find expenses.wsgi This is my structure: v expenses v expenses > static __init.py asgi.py settings.py urls.py wsgi.py > finances manage.py Procfile requirements.txt runtime.txt I tried changing the Procfile from gunicorn expenses.wsgi to gunicorn expenses.expenses.wsgi but then I will tell my to change os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'expenses.settings') inside the wsgi.py I tried changing the wsgi.py from os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'expenses.settings') to os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'expenses.expenses.settings') but then it will tell me that it couldn't find the module finances. -
Djnamic checkbox, change and disabled or unhide when select
I have three columns named "passive", "discount" and "discountprice" in the rows coming from the database. I use checkbox. If the passive is full, when one of the data-x with the passive label is selected, the others will be disabled. If the discount is full, when one of the ones with the data-y discount tag is selected, the discount price of those with the same discount tag will replace the normal price. It cannot be both discounted and passive. There may be different discount groups or liability groups. I'm stuck.

Which languange/framework should I use? [closed]
I'm getting ready to do my final project. It should be a web app that will show fitness progress by entering it into the system. The progress just given, which has to be written down by the user, will be shown in the form of a graph. I am mainly concerned about the look of the overall application, but at the same time a good backend of course with a database. The original idea was to use Python with Django and React for frontend. But recently I was recommended to use Next.js for both frontend and backend. What is your opinion on what you would use? Or do you have any other opinion? -

Choose which model manager to use when doing prefetch_related?
I have a Product model in my Django app, which uses a custom model manager where all the prefetch_related statements are made: class ProductManager(models.Manager): def get_queryset(self): return ( super() .get_queryset() .select_related("core_product") .prefetch_related("images") .prefetch_related("bundled_products") ) class Product(models.Model): _base_manager = ProductManager objects = ProductManager() # ... model fields This works fine; when I use the ORM and within the Admin the custom manager is used, preventing a whole bunch of duplicate queries. The problem is when I have another model that has a prefetch_related to the Product model: it now inherits all the prefetch_related from the Product, even though that's not necessary. It causes a whole bunch of unnecessary queries to be made. class OfferManager(models.Manager): def get_queryset(self): return ( super() .get_queryset() .select_related("flag") .prefetch_related("condition_products") .prefetch_related("limited_to_users") .order_by("-priority") ) Here the condition_products field is that Product model from above, and just by including this prefetch_related, all of its prefetch_related statements are also inherited. How can I prevent this from happening? Can I specify which object manager to use in the prefetch_related - so that is uses a "bare" manager?
