What solid alternatives are there to Django's `UniqueConstraint` with a condition?
Goal: I want to ensure there is only one active owner per Thing. Problem: As our DB is MySQL, I can't use the condition parameter of Django's UniqueConstraint. I'm looking for a reliable, scalable alternative to this: class Thing(models.Model): owner = models.ForeignKey(User, on_delete=models.CASCADE) active = models.BooleanField() class Meta: constraints = [ UniqueConstraint( fields=['owner'], condition=Q(active=True), name='one_active_owner_per_thing' ) ] Would it be best to create a separate table for active Things, override the save method, or something else? -

Data not persisting on Docker - Windows 10 Volumes docker-compopse.yml
Thanks for having a look at this. I'm getting started with using Docker along Django and while trying to set up postgres to have its own volume in order to have data persisting after docker-compose down, it isn't saving at all. Steps: 1) docker-compose up -d 2) docker-compose exec web python manage.py migrate 3) docker-compose exec web python manage.py createsuperuser 4) check if all is fine at the /admin and that user exists 5) docker-compose down Then when running it back up: 1) docker-compose up -d 2) check /admin and have errors that are only resolved if I run step 2 and 3 above. I'm using Windows 10. I have tried setting this env var as recommended by other posts but without success: COMPOSE_CONVERT_WINDOWS_PATHS=1 The directory (full path) I am working on is also shared at the Docker/Settings/Resources/File Sharing area. Any idea on how to solve this? Thanks a lot! docker-compose.yml version: '3.7' services: web: build: . command: python /code/manage.py runserver 0.0.0.0:8000 volumes: - .:/code ports: - 8000:8000 depends_on: - db db: image: postgres:11 volumes: - postgres_data:/var/lib/postgresql/postgres_data/ environment: - "POSTGRES_HOST_AUTH_METHOD=trust" volumes: postgres_data: -

Django using "." as primary key gives 404
I am using DRF along with drf-nested-routers to configure my routing. I have an api route structure this way. /posts/1/comments Now instead of using the id I have decided to use the name of the object instead. /posts/mypost/comments This works perfectly but an issue occurs when a . is being added to the key. /posts/my.post/comments When including a . as part of the key for the resource, it returns a 404 error on Django.

What does ProgrammingError mean?
I am having these ProgrammingErrors occurring on my production server lately. The page which the user is submitting a form at is a UserCreateView and is being redirected to the phone-verification page. The error reads: Internal Server Error: /phone-verification/ ProgrammingError at /phone-verification/ column quiz_sitting.percent_correct does not exist LINE 1: ...rrect_questions", "quiz_sitting"."current_score", "quiz_sitt... ^ I am not sure why its looking at quiz_sitting in the database because /phone-verification/ has nothing to do with that. The view for /phone-verification/ looks like this: @login_required def phone_verify_check(request): employee = request.user phone_verify, _ = PhoneVerify.objects.get_or_create(employee=employee) login_tracker = EmployeeLogin.objects.create(employee=employee, ip_address=get_client_ip(request)) login_tracker.save() if phone_verify.verified: return redirect('dashboard') else: return redirect('resend') I am using Django tenant schemas for handling subdomains which means when I run a migration it looks like: python manage.py makemigrations python manage.py migrate_schemas --shared python manage.py migrate_schemas --tenant I recently deleted all my migrations because I was having these ProgrammingErrors on another page and then I ran the makemigrations etc again and it seemed to have fix it. But now it is occurring again. I really hope there isn't some sort of corruption in the database like columns being mixed up. Any help is greatly appreciated! -
