You cannot call this from an async context - use a thread or sync_to_async. Django ORM
I wrote the following code: class BookmakerA: def __init__(self) -> None: self.bookmaker = None async def _init(self): self.bookmaker, _ = await Bookmaker.objects.aget_or_create(name="BookmakerA", defaults={"name": "BookmakerA"}) I call this class from a Celery task which looks as follows: @shared_task def get_bookmaker_matches(): start = time.time() bookmakera = BookmakerA() loop = asyncio.new_event_loop() asyncio.set_event_loop(loop) loop.run_until_complete(bookmakera._init()) This however results in the following error: django.core.exceptions.SynchronousOnlyOperation: You cannot call this from an async context - use a thread or sync_to_async. Why does this happen and how do I resolve this. Using Django 4.2.6 which supports async ORM (acreate_or_create, aget, so on) -

custom permissions in django DRF class based view
I'm trying to set custom permissions in a ModelViewSet. I want to allow any authenticated user to list and retrieve items but only Admin and Manager can create, update, and destroy.

Django REST: endpoint for creating multiple models
In my service, when registering a user, two entities must be created: the user and the company, to which the user entity will be immediately linked. To do this, I created an endpoint in which I use two serializers (for the user and for the company). But there are some problems with this solution: Fields for one of the serializers are not displayed in Django Spectacular (Swagger); Fields for one of the serializers are not available in the DRF BRowsable API; Ugly code; class UserCreateViewSet(mixins.CreateModelMixin, viewsets.GenericViewSet): """ Creates user accounts """ queryset = User.objects.all() serializer_class = CreateUserSerializer permission_classes = (AllowAny,) REQUIRED_FIELDS = ( 'email', 'password', 'position', 'company_name', 'phone_number' ) def create(self, request, *args, **kwargs): data = request.data provided_fields = set(data.keys()) for field in self.REQUIRED_FIELDS: if field not in provided_fields: return Response( {"detail":f"{field} not provided"}, status=400 ) # --- Creating company for user data['name'] = data['company_name'] company_serializer = CompanyReducedSerializer(data=request.data) company_serializer.is_valid(raise_exception=True) self.perform_create(company_serializer) data['company'] = company_serializer.data['id'] # --- # Code from super() # --- Creating user user_serializer = self.get_serializer(data=request.data) user_serializer.is_valid(raise_exception=True) self.perform_create(user_serializer) headers = self.get_success_headers(user_serializer.data) # --- return Response( status=201, data=user_serializer.data, headers=headers ) I considered options using multi-table inheritance, but for some reasons, this solution does not suit me.

Django ManyToMany creations and cascading deletions
Django ManyToMany creations and cascading deletions Django newbie here. I have looked under several threads and I have not found anything related so I hope you can help me out on this. I am working on a ManyToMany model involving Doctors and Patients, that is, both can have multiple relationships between them. I have the following model definition: class Patient(models.Model): first_name = models.CharField(max_length=255) last_name = models.CharField(max_length=255) email = models.EmailField(unique=True) (other fields definitions) class Doctor(models.Model): first_name = models.CharField(max_length=255) last_name = models.CharField(max_length=255) email = models.EmailField(unique=True) (other fields definitions) … patients = models.ManyToManyField(Patient) The doctor is the main user that should be able to visualize all related patients (no problem there). When adding a new patient though, I would like to know how to create the relationship in the app_doctor_patients join table. I’ve read the documentation regarding the Related objects reference (https://docs.djangoproject.com/en/4.2/ref/models/relations/#django.db.models.fields.related.RelatedManager) but I do not know which is the best way to apply these functions. For starters, I visualized the following: def add_new_patient(request, doctor_id=None, curp=None): doctor = Doctor.objects.get(id=doctor_id) try: patient = Patient.objects.get(curp=curp) # Associates Patient 'patient' with Doctor 'doctor'. doctor.patients.add(patient) except Patient.DoesNotExist: # Creates a new patient object, saves it and puts it in the related object set. Returns the newly created … -
How can I create a views.py that allows a registered user to create, amend and delete a appointment?
I am developing a barber booking service using Django/Python. I want to create a view for an authenticated user to create a booking, amend and/or delete their booking. I am a student developer and this particular issue is not covered in the lessons and I am a little overwhelmed by it all, I have done many searches online but have not had any luck with finding anything I am able to work with. So far I have managed to create the models.py code but have hit a brick wall when it comes to creating the views.py, any help or advice is greatly appreciated! My current models.py file from django.db import models from datetime import datetime from django.contrib.auth.models import User SERVICE_CHOICES = ( ("Classic Cut", "Classic cut"), ("Cut & Beard", "Cut & Beard"), ("Skin Fade", "Skin Fade"), ("Skin & Beard", "Skin & Beard"), ("Buzz Cut", "Buzz Cut"), ) TIME_CHOICES = ( ("9 AM", "9 AM"), ("10 AM", "10 AM"), ("11 AM", "11 AM"), ("1 PM", "1 PM"), ("2 PM", "2 PM"), ("3 PM", "3 PM"), ("4 PM", "4 PM"), ("5 PM", "5 PM"), ) class Appointment(models.Model): user = models.ForeignKey( User, on_delete=models.CASCADE, null=True, blank=True) service = models.CharField( max_length=50, choices=SERVICE_CHOICES, default="Classic Cut") day … -
Weird error produced when quering sqlite databased using a model
I'm getting a very weird decimal.InvalidOperation: [<class 'decimal.InvalidOperation'>] when trying to query a table in my Django application. I suspect it may be related to the virtual environment. This is the view. It is an endpoint that will receive some JSON data (at the moment I'm using Postman to send data to it). def handleRawMarketData(request): if request.method=='POST': data = json.loads(request.body) print(data) for item in data: new_data = rawMarketData(duration=item['duration'], is_buy_order=item['is_buy_order'], issued = item['issued'], location_id = item['location_id'], min_volume = item['min_volume'], order_id = item['order_id'], price = item['price'], range = item['range'], typeID = InvTypes.objects.get(typeID = item['type_id']), volume_remain = item['volume_remain'], volume_total = item['volume_total']) new_data.save() return JsonResponse({'message': 'Data saved successfully'}) return JsonResponse({'message': 'Failed'}) This is the data being sent in the body of the POST request by Postman: [{"duration":90,"is_buy_order":true,"issued":"2023-10-03T10:21:32Z","location_id":1038457641673,"min_volume":1,"order_id":6512967679,"price":17720000,"range":"region","type_id":19255,"volume_remain":2,"volume_total":3},{"duration":90,"is_buy_order":true,"issued":"2023-10-17T20:31:19Z","location_id":1038457641673,"min_volume":1,"order_id":6616121350,"price":500.2,"range":"station","type_id":24509,"volume_remain":198250,"volume_total":200000}] These are the two models being used. class InvTypes(models.Model): typeID = models.IntegerField(db_column='typeID', primary_key=True) groupid = models.IntegerField(db_column='groupID', blank=True, null=True) typename = models.CharField(db_column='typeName', blank=True, null=True, max_length=10000) description = models.TextField(blank=True, null=True) mass = models.IntegerField(blank=True, null=True) volume = models.IntegerField(blank=True, null=True) capacity = models.IntegerField(blank=True, null=True) portionsize = models.IntegerField(db_column='portionSize', blank=True, null=True) raceid = models.IntegerField(db_column='raceID', blank=True, null=True) baseprice = models.DecimalField(db_column='basePrice', max_digits=10, decimal_places=5, blank=True, null=True) published = models.BooleanField(blank=True, null=True) marketgroupid = models.IntegerField(db_column='marketGroupID', blank=True, null=True) iconid = models.IntegerField(db_column='iconID', blank=True, null=True) soundid = models.IntegerField(db_column='soundID', blank=True, null=True) graphicid … -

Django Rest Framework SimpleJWT - Removing a variable refrencing 'request.body' Causes 'RawPostDataException' Error
I have a Django 4.2.6 project using Python 3.10 and the rest_framework_simplejwt library. I've implemented a signin function, and it works fine when I include the line body = request.body, even though I'm not using body anywhere in the function. However, when I remove this line, it throws the following error: “RawPostDataException at /auth/signin/ - You cannot access the body after reading from the request's data stream.” I've tried to understand why this is happening, but I couldn't figure it out even after reading the docs. Can someone help me understand why this line is needed and if there's a cleaner or better way to write this function? Here's my code: @api_view(['POST']) def signin(request): body = request.body token_view = jwt_views.TokenObtainPairView.as_view() token_response = token_view(request._request) if token_response.status_code == status.HTTP_200_OK: data = request.data user = User.objects.filter(username=data['username']).first() data = { "access_token": str(token_response.data['access']), "refresh_token": str(token_response.data['refresh']), "user_access": { "is_staff": user.is_staff, "is_admin": user.is_superuser } } return Response(data, status=status.HTTP_200_OK) return token_response
