Django @login_required doesn't work when login function has redirect
In login view I have: def login_signup(request): ... login(request, user) messages.success(request, 'You have successfully logged in to your account.') return redirect('user_app:profile') In some other function I have @login_required(login_url='/login/') but their redirect doesn't work and allways redirect to user_app:profile. How do I redirect a user to page he/she redirected from it to login page, and redirect to the profile page only when he/she referred directly to the login page? -
How to annotate to query with a custom function in Django ORM?
I have this model: class Brand(models.Model): name = models.CharField(max_length=32) and this function that returns a number that shows similarity between two strings (a number between 0 and 1). from difflib import SequenceMatcher def similar(a, b): return SequenceMatcher(None, a, b).ratio() I want to annotate a column to my query that shows similarity value between name and a string and order them by similarity. I wrote something like this but it won't work and I don't know how it works. Brand.objects.all().annotate( similarity=ExpressionWrapper(similar(F('name'), 'mercedes'), output_field=models.DecimalField()).order_by('similarity') ) If there is another way to do it please let me know. -

Domain based email senders in app engine in a django application
I have a google app engine django application, I want to send emails through a custom domain mail. When I try to add the domain mail user@domain.com to mail senders in app engine, I get the error : The following emails could not be added because they are on a different domain. The email must be associated with a Google Apps domain or Google group. If the email is associated with a Google group, your role in the group must be Owner or Manager: The site is hosted on google domains and registered on Google Workspace. I have added the google SPF Record and the email is the owner of the domain yet still produces the error. I have added the DNS Records to the Google Domain Records, yet it cannot allow the email to be added to the email senders on app engine. Is there a way I can make it work other than using other party mail senders like sendgrid -

How to load data lazily in Django admin list page
I have a lot of annotations in admin page by customizing def get_queryset(self, request: HttpRequest) -> QuerySet: in ModelAdmin and using them in list_display. This has made admin page loading extremely slow. Is there a way to load the annotated fields lazily for each row in django admin list page? For example I rewrite the get_queryset and load the other data separately for each row lazily. I appreciate any help or idea:) -
Cron Scheduler in Django
I use Scheduler in Django/Windows IIS from apscheduler.schedulers.background import BackgroundScheduler to run my background script. Problem is, taks gets run multiple times. If I run same program on my PC, it only runs once, but when I upload to windows server (which hosts my Django app) it runs more times. First 2, then 14, then again 14. Code scheduler.add_job(cron_mail_overdue, "cron", hour=7, minute=14, day_of_week='mon-sun', id="task002", replace_existing=True) For test I put scheduler.add_job(cron_mail_overdue, "interval", minutes=1, id="task002",replace_existing=True) It's the same, I did this just to test. It does the same no matter the task I run. Why does it run more then once? And why not always the same number? First 2 times, then 14. Taks sends email, so I get 14 emails, all received at same time. -

Returning a Unix Timestamp when querying a DateTimeField
In Django, I have the following query dates = ( Event.objects.filter(cancelled=False) .exclude(id=event.id) .aggregate( first_date=Min('start'), last_date=Max('start'), next_date=Min('start', filter=Q(date__gt=timezone.now().date())), recent_date=Max('start', filter=Q(end__lt=timezone.now())) ) ) and I would like to annotate the query so that my lesson dates are returned as unix timestamps rather than datetime objects. I recognize I can simply do something like dates.next_date.timestamp(), but this causes an error when dates.next_date is None, and I'd rather not have to repeatedly check that my object is not None before getting its timestamp. How could I go about this? I have searched through many other answers and the Django docs but haven't been able to find anything I could specifically apply here. Thanks in advance! -
