API not working after giving authentication permission
I created an API to list the employees and applied authentication permission. when I tried to load the page it shows a login page. After giving the login credentials it shows a page not found error. Before the authentication the url's was working perfectly. views.py from rest_framework.permissions import IsAdminUser class EmpListView(ListAPIView): queryset = Employee.objects.all() serializer_class = EmpModelSerializer filter_backends = [filters.SearchFilter] search_fields = ['Ename', 'Position'] permission_classes = [IsAdminUser] urls.py urlpatterns = [ path('admin/employee/', EmpListView.as_view(), name='emp-list'),] -
Custom serializer.py failed django.db.utils.IntegrityError: null value in column violates not-null constraint
What i am trying to do - is to save post to the model with custom conditions.

How to add these constraints to Django models?
Help me please. How to make constraints in the database? I am using sqlite, django 3.2, python 3.7 I have three models: Refbook, Versions of refbooks, Elements of refbook from django.db import models class Refbook(models.Model): code = models.CharField(max_length=100, unique=True) name = models.CharField(max_length=300) description = models.TextField() class VersionRefbook(models.Model): refbook_id = models.ForeignKey('Refbook', on_delete=models.CASCADE, related_name='versions') version = models.CharField(max_length=50) date = models.DateField() class Meta: unique_together = ('refbook_id', 'version') class Element(models.Model): version_id = models.ManyToManyField('VersionRefbook') code = models.CharField(max_length=100) value = models.CharField(max_length=300) The following constraints must be added to these models: There cannot be more than one Refbook with the same value in the "code" field. There cannot be more than one Version with the same set of values "refbook id" and "version" One Refbook cannot have more than one Version with the same date In one Version of refbook, there cannot be more than one Element of refbook with the same value in the "code" field OK. I solved the first point by adding the «unique=true» parameter to the «code» field in the Refbook class. It seems that I solved the seconf point by adding the «unique_together = ('refbook_id', 'version')» parameter to the Meta class. Third point. I think need to override the save method. But … -
Django: how to access inline fields from parent model form
I am working on a simple quiz application. There will be questions which are either multiple choice or open. From the admin site, I want to be able to add questions along with their related answers, while having the following validation: If a question's type is multiple choice, then it must have 4 possible answers and only of them should be marked as correct. If a questions's type is open then it must have only 1 answer and it must be marked as correct. Here is the relevant part of the Question and Answer models that I have. class Question(models.Model): class QuestionType(models.TextChoices): MULTIPLE_CHOICE = "MC" OPEN = "OP" text = models.CharField(max_length=250) topic = models.ForeignKey(Topic, on_delete=models.PROTECT) class Answer(models.Model): text = models.CharField(max_length=150) is_correct = models.BooleanField() question = models.ForeignKey(Question, on_delete=models.CASCADE) And here is what I have in admin.py class AnswerInline(admin.TabularInline): model = Answer class QuestionAdmin(admin.ModelAdmin): fields = ["text", "topic", "type", "difficulty"] inlines = [AnswerInline] def clean(self): """ How do I access the is_correct values of the items which are in the AnswerInline instance?

Why am I getting "Volumes must be mapping" error
Trying to add Django app with a PostgreSQL db to a Docker container. When trying to run "docker-compose build", I am getting a "Volumes must be mapping" error. Not sure what I'm doing wrong as it looks like the : syntax signified a mapping. When I remove the volumes sections entirely the build continues (with or without a Dockerfile reference so I've omitted that part). See docker-compose.yml: version: "3.9" services: app: build: context: . args: - DEV=true ports: - "8000:8000" volumes: - dev-static-data:/backend/django_static command: > sh -c "python manage.py wait_for_db && python manage.py migrate && python manage.py runserver 0.0.0.0:8000" environment: - DB_HOST=db - DB_NAME=devdb - DB_USER=devuser - DB_PASS=changeme - DEBUG=1 depends_on: - db - redis db: image: postgres:15-alpine volumes: - dev-db-data:/var/lib/postgresql/data environment: - POSTGRES_DB=devdb - POSTGRES_USER=devuser - POSTGRES_PASS=changeme volumes: - dev-db-data: - dev-static-data: Any ideas? -

setting up database for @shared task using celery django
The application I am working on is a multitenant application. I am using celery to run background tasks. The background tasks that get pushed to Queue (rabbitmq) are getting executed properly when run on the default db setting configured in the settings. But when I submit the background jobs from other tenants, i.e. settings other than default they fail. This is because, in normal sync flow, I am using a custom router that sets the DB to be used based on the request URL( which contains the tenant details). but the same context is lost when the job is submitted as a background task. Any suggestions ? -

Safari does Preflight Request for same origin
I am currently testing my Web Application with different devices and for most of them everything works as intended. Sadly with my IPhone and Safari i am experiencing a weird issue, that it does a Preflight Options Request, when its the same origin. To my Knowledge this is not required. Sadly the Options fails. When testing with Chrome on the same device everything worked. I also tested Safari on a different Iphone and it worked there. Now the really confusing part is, when clicking on a link to the website in Discord for example with safari it works aswell without doing a Options. I know that in a "perfekt" World the Options should not fail, but that is another struggle when i was deploying the app. Currently frontend runs under https://example.com and the API under https://example.com/api. I am a absolute beginner with CORS and i am quite confused why this error happens. Another problem is that i cant really use devtools on the iphone to have a exact error message. I can only see the Options in the nginx logs and then the missing follow up request. -

Django ORM JOIN of models that are related through JSONField
If I have 2 models related through ForeignKey I can easily get a queryset with both models joined using select_related class Foo(Model): data = IntegerField() bar = ForeignKey('Bar', on_delete=CASCADE) class Bar(Model): data = IntegerField() foos_with_joined_bar = Foo.objects.select_related('bar') for foo in foos_with_joined_bar: print(foo.data, foo.bar.data) # this will not cause extra db queries I want to do the same thing but in the case where Foo keeps it's reference to bar in a JSONField class Foo(Model): data = IntegerField() bar = JSONField() # here can be something like {"bar": 1} where 1 is the ID of Bar class Bar(Model): data = IntegerField() foos_with_joined_bar = ??? Is it possible to get foos_with_joined_bar in this case using Django ORM? P.S. We're not discussing the reasoning behind storing foreign keys in the JSONField, of course it's better to just use ForeignKey. -
