Django model filter with "exact" IN operator
I want to find all users who have exactly same tags like a particular category (exactly same tags and also same amount of tags assigned) Something like... category = Category.objects.first() User.objects.filter(tags__in=category.tags.filter()) But this returns also users who share even only one tag with the category. Models are class User(models.Model): tags = models.ManyToManyField(Tag, blank=True, related_name='users') class Category(models.Model): tags = models.ManyToManyField(Tag, blank=True, related_name='categories') class Tag(models.Model): name = models.CharField(max_length=255, blank=False) Any solution appreciated. -
Django async access to related objects from .aget()
I have done some extensive searches and read the documentation. Unfortunately I could not solve the following. I probably missed something. ` async def generate_quotes(request, id): try: interrogation = await Interrogation.objects.aget(id=id) except Interrogation.DoesNotExist: return JsonResponse("Interrogation does not exist") print(interrogation.address.postcode) #where address is a onetoone related object with related name address i get a keyerror for address anddjango.core.exceptions.SynchronousOnlyOperation: You cannot call this from an async context - use a thread or sync_to_async.` I am stuck on how to proceed. I have tried sync to async in all manner of ways with that one print statement and still nothing. I cant seem to get to the address object through its related interrogation object query result. I thought maybe it's to do with caching related objects. Any help would be greatly appreciate ! Thanks -
Why is the data being passed to the serializer saving as null in the database?
I've been working on this Django project with a rest framework serializer to take info sent from the front-end organize it and save it in the database. The info is made by drawing boxes over input fields on forms and sending all the fields you define. However, it's as though the data isn't actually being used after defining DataSerializer(data=data). An example of request.data = {'TextField': [], 'DateField': [], 'SignatureField': [['FieldName', [129, 79], [138, 35], 'Form.jpg']]} Here's my serializer: Class DataSerializer(serializers.ModelSerializer): class Meta: model = FormData fields = ["FieldName", "StartX", "StartY", "width", "height", "JSONData", "FormType"] def create(self, **validated_data): print(**validated_data) return FormData.objects.create(**validated_data) Here's my post View @api_view(['POST']) def create_list(request): if request.method == 'POST': dataDict = request.data for info in dataDict: Field = dataDict[info] stringDict = str(dataDict) for object in Field: datadict = { "FieldName": object[0], "StartX": object[1][0], "StartY": object[1][1], "width": object[2][0], "height": object[2][1], "JSONData": stringDict, "FormType": object[3] } serializer = DataSerializer(data=datadict) if serializer.is_valid(): serializer.create() return JSONResponse(serializer.data, status=201) print(serializer.errors) return Response("Not Valid") Here's my model which has been modified to accept null values not gonna be the case after I figure this out. class FormData(models.Model): FieldName = models.CharField(max_length=100) StartX = models.IntegerField(null=True) StartY = models.IntegerField(null=True) width = models.IntegerField(null=True) height = models.IntegerField(null=True) JSONData = models.CharField(max_length=500) … -
django-filter python class sub function under __init__ function not receive value return

CustomUser has no customer error for users signed in with google
I have a CustomUser model to differentiate between customer and merchant. class CustomUser(AbstractUser): is_customer = models.BooleanField(default=False) is_merchant = models.BooleanField(default=False) is_superuser = models.BooleanField(default=False) first_name = models.CharField(max_length=255) last_name = models.CharField(max_length=255) Now the customers have the add to cart functionality for which I have a utils.py def cartData(request): if request.user.is_authenticated: customer = request.user.customer order, created = Order.objects.get_or_create(customer=customer, complete=False) items = order.orderitem_set.all() cartItems = order.get_cart_items else: cookieData = cookieCart(request) cartItems = cookieData['cartItems'] order = cookieData['order'] items = cookieData['items'] return {'cartItems':cartItems ,'order':order, 'items':items} As per the utils.py I always need request.user.customer. The customer instance here is created during customer registration. forms.py: @transaction.atomic def save(self): user = super().save(commit=False) user.is_customer = True user.first_name = self.cleaned_data.get('first_name') user.last_name = self.cleaned_data.get('last_name') user.username=self.cleaned_data.get('username') user.email=self.cleaned_data.get('email') user.phone_number=self.cleaned_data.get('phone_number') user.address=self.cleaned_data.get('address') user.save() customer = Customer.objects.create(user=user) customer.first_name=self.cleaned_data.get('first_name') customer.last_name=self.cleaned_data.get('last_name') customer.username=self.cleaned_data.get('username') customer.email=self.cleaned_data.get('email') customer.phone_number=self.cleaned_data.get('phone_number') customer.address=self.cleaned_data.get('address') customer.save() return user So with the customer, everything worked just fine.

Django add function to "from" clause?
I'm trying to write a Django query that generates the following: select group_id, cardinality(array_agg(distinct aul)) from report_table, unnest(active_user_list) as aul group by group_id Where active_user_list is an array[int] type. I'm trying to get a count of the unique items in the arrays of all rows that are in a group. The queryset.extra method gets me very close to this, but adds double quotes around unnest(active_user_list) as aul and doesn't work. I created a custom sql function that does work, but I'd prefer to do it in Django if possible. -

How to make Model Save method the PK gets incremented by n number

Network exception error when trying to use Daphne with GreaterWMS

How to make Model's PK as FK to all Django's Project Models
I need some help to figure out what's the best way to design following model use case in Django. I have model "Client" which defines client id for an app. This model needs to refer as a foreign key to all models of project. Here is code snippet: Class Client(Model): ClientId = models.AutoField(primary_key=True) Class Location(Model): LocationId = models.AutoField(primary_key=True) ClientId = models.ForeignKey(Client, on_delete=models.CASCADE, db_column="ClientId") Class User(Model): UserId = models.AutoField(primary_key=True) ClientId = models.ForeignKey(Client, on_delete=models.CASCADE, db_column="ClientId") Class Document(Model): DocumentId = models.AutoField(primary_key=True) ClientId = models.ForeignKey(Client, on_delete=models.CASCADE, db_column="ClientId") As shown above, Location, User and Document all have ClientId as FK. It works however.... Issue with above design is that I have to explicitly specify ClientId as FK in each table. As ClientID is required FK for each models of Project, I want to know if there is any simple design pattern where ClientId is defined as FK to each model without specifying it. I have thought of using inheritance but that does not work as there is only one Global ClientId and defining Client as Parent for each model means it creates Client Id each time new instance of child is created. Any idea or pointer to this issue. -

How to create a case insensitive choice field from DRF normal choice field?
I am trying to create a case insensitive choice filed such as CaseInsensitiveChoiceField that inherits and modifies serializers.ChoiceField suppose I a creating a serializer as below from rest_framework import serializers my_field_choices = ["A", "BCD", "e"] class MySerializer(serializers.Serializer): my_field = serializers.ChoiceField(choices=my_field_choices) this serializer does not validate if I pass data={"my_field": "a"} or data={"my_field": "BCd"} or {"my_field": "e"} to it. what I could do was from rest_framework import serializers my_field_choices = ["A", "BCD", "e"] class MySerializer(serializers.Serializer): my_field = serializers.ChoiceField(choices=[item.upper() for item in my_field_choices]) and then modify the data and then pass it to it: data = request.body data["my_field"] = data["my_field"].upper() However, this is not very clean and I dont want to modify the request body because of validation. I am looking for a way to create a CaseInsensitiveChoiceField that tweaks ChoiceField and inherits from it. any idea how to do that? I dont clearly understand how these serializers and fields work. Otherwise, I may be able to do this. -
