Django Rest Framework custom permission not working
I want users to have access only to the records that belong to them, not to any other users' records so I've created the following view: class AddressViewSet(viewsets.ModelViewSet): authentication_classes = (TokenAuthentication,) permission_classes = [IsAuthenticated, IsOwner] queryset = Address.objects.all() def retrieve(self, request, pk): address = self.address_service.get_by_id(pk) serializer = AddressSerializer(address) return Response(serializer.data, status=status.HTTP_200_OK) I want only the owner of the records to have access to all the methods in this view ie retrieve, list, etc (I'll implement the remaining methods later) so I created the following permissions.py file in my core app: class IsOwner(permissions.BasePermission): def has_object_permission(self, request, view, obj): print('here in has_object_permission...') return obj.user == request.user this wasn't working, so after going through stackoverflow answers I found this one Django Rest Framework owner permissions where it indicates that has_permission method must be implemented. But as you can see in that answer, it's trying to get the id from the view.kwargs but my view.kwargs contains only the pk and not the user. How can I fix this? Do I need to implicitly pass the user id in the request url? that doesn't sound right. Here's the test I'm using to verify a user cannot access other user's records: def test_when_a_user_tries_to_access_another_users_address_then_an_error_is_returned(self): user2 = UserFactory.create() … -
How to set up different weekday/weekend schedules for celery beat in Django?
How do I go about scheduling my tasks differently for weekdays and weekends in celery beat? The schedule is set as follows in my settings.py file { "task_weekday": { "task": "tasks.my_regular_task", "schedule": crontab(minute="0-30", hour="4,5", day_of_week="mon-fri"), "options": {"queue": "queue_name"}, }, "task_weekend": { "task": "tasks.my_regular_task", "schedule": crontab(minute="0-5", hour="10,12", day_of_week="sat,sun"), "options": {"queue": "queue_name"}, }, } However when I set it up, it ran the weekday schedule today (3/21/2021 Sunday) instead of picking up the weekend schedule. I have the app timezone set to 'US/Pacific' and the CELERY_ENABLE_UTC is set to False. After setting it up I see the following log entry but it runs the weekday tasks schedule. [2021-03-21 17:57:50,082: DEBUG/MainProcess] Current schedule: <ScheduleEntry: task_weekday tasks.my_regular_task() <crontab: 0-30 4,5 mon-fri * * (m/h/d/dM/MY)> <ScheduleEntry: task_weekend tasks.my_regular_task() <crontab: 0-5 10,12 sat,sun * * (m/h/d/dM/MY)> <ScheduleEntry: celery.backend_cleanup celery.backend_cleanup() <crontab: 0 4 * * * (m/h/d/dM/MY)> I have tried running the tasks every few minutes as well to test which schedule it picks up and picks up the weekend schedule: { "task_weekday": { "task": "tasks.my_regular_task", "schedule": crontab(minute="*/2", hour="*", day_of_week="mon-fri"), "options": {"queue": "queue_name"}, }, "task_weekend": { "task": "tasks.my_regular_task", "schedule": crontab(minute="*/3", hour="*", day_of_week="sat,sun"), "options": {"queue": "queue_name"}, }, } [2021-03-21 18:03:27,075: DEBUG/MainProcess] Current schedule: <ScheduleEntry: task_weekend tasks.my_regular_task() <crontab: */3 … -

Data from django form is not being posted in Postgressql Database despite getting 200 OK from the server

Docker compose with nginx, django backend and react frontend

Django - Saving function value to every model instance
So I have this model: class Profile(models.Model): ip = "placeholder" user = models.OneToOneField(User, on_delete=models.CASCADE, related_name="profile") image = models.ImageField(default='default.jpg', upload_to='profile_pics') location = models.CharField(max_length=100, default=ip) def __str__(self): return f'{self.user.username} Profile' and the following function: def get_ip_address(request): x_forwarded_for = request.META.get('HTTP_X_FORWARDED_FOR') if x_forwarded_for: ip = x_forwarded_for.split(',')[0] else: ip = request.META.get('REMOTE_ADDR') return ip ip = get_ip_address(request) What what I need to do to make it so that every time an instance of the model is created, the function runs and saves the returned value in the field called location. I assume that I have to put the function in the views.py file but how do I link it to the model instances. -
