How can I make a single query in Django and get only those users who have an entry in the table with one product and not with another?
I have two tables: one with users(where only the name and ID), the other with the purchases of these users. I want to get for one request users who have 'car' and no 'bike' among the purchased products. How do I do this? My Models: class Client(models.Model): name = models.CharField(max_length=200) class Purchases(models.Model): client = models.ForeignKey(Client, on_delete=models.PROTECT) product = models.CharField(max_length=200) -
JSON array out of order
I have a React/Django application where users can answer multiple choice questions. I have the "choices" array rendered onto the UI in this exact order. { "id": 2, "question_text": "Is Lebron James the GOAT?", "choices": [ { "id": 5, "choice_text": "No", "votes": 0, "percent": 0 }, { "id": 4, "choice_text": "Yes", "votes": 1, "percent": 100 } ], } When I select a choice in development mode, I send a request to Django to increment the votes counter for that choice and it will send back a response with updated votes in the same order. When I try to select a choice in production mode using npm run build, the order becomes switched. { "id": 2, "question_text": "Is Lebron James the GOAT?", "choices": [ { "id": 4, "choice_text": "Yes", "votes": 1, "percent": 50 }, { "id": 5, "choice_text": "No", "votes": 1, "percent": 50 } ] } I thought the order of JSON array must be preserved. Can anyone explain why this is happening? I'm almost positive that this issue is originating from Django. Here is the function view on Django. @api_view(['POST']) def vote_poll(request, poll_id): if request.method == 'POST': poll = Poll.objects.get(pk=poll_id) selected_choice = Choice.objects.get(pk=request.data['selected_choice_id']) selected_choice.votes += 1 selected_choice.save() poll_serializer = PollAndChoicesSerializer(poll) … -
Django - How to dynamically choose base template
I want to choose which base template to use in my Django project from a possible three options. I sourced online and, from this link, I saw: Use a variable. {% extends base_template %} and in your view, set it to "base.html" in your view, or a new "ajax.html" file which just provides the block and nothing else. But a comment to that answer reads: This breaks django-compressor offline compression. I do not know what that means Another answer said: {% extends request.is_ajax|yesno:"app/base_ajax.html,app/base.html" %} But I am not making AJAX request. From this answer, I discovered the yesno Django provides. This works just for True or False; more like if-else statement. How can I achieve if, else and else-if statements ? Because that seems to be one way I could achieve what I am trying to achieve. But if you have better options, please pour it out. Here is what I tried {% if user_type == 1 %} {% extends 'hod_template/base.html' %} {% load static %} {% elif user_type == 2 %} {% extends 'staff_template/base.html' %} {% load static %} {% else %} {% extends 'student_template/base.html' %} {% load static %} {% endif %} But I got Invalid block tag … -
Cannot pull the value from the key of a session dictionary in django
I have a session variable for the name of a company saved in my django view from a user input form. When I try and use this in a later view, no matter what I try it pulls the {key: value} pair rather than just the value Views: def start(request): if request.method == 'POST': # create a form instance and populate it with data from the request: form = QuizTakerForm(request.POST ) # check whether it's valid: if form.is_valid(): # process the data in form.cleaned_data as required post = form.save(commit=False) post.user = request.user post.save() request.session['obj_id'] = post.id request.session['company_name'] = form.cleaned_data # redirect to a new URL: return HttpResponseRedirect('industry/') .... def Gov_q1(request): company_name = request.session.get('company_name') print(company_name) question = Question.objects.get(pk=24) context = {'question': question, 'company_name': company_name} return render(request, 'ImpactCheck/detail.html', context) html: <h1> Hi my name is {{ company_name }} </h1> <h1>{{ question.text }}</h1> <form action="." method="post"> {% for answer in question.answer_set.all %} <input type="radio" name="answer" id="answer" value="{{ answer.id }}"> <label for="answer">{{ answer.answer_text }}</label><br> {% endfor %} <input type="submit" value="Submit"> </form> Ive also tried company_name=request.session['company_name'], but both then render as {'company_name': 'test_company'} rather than test_company. -
How to use a list in Django query for addition of fields
I like to perform a Django query like the one below: query = Dbmodel.objects.all().annotate(result=F('fieldname1') + F('fieldname2') + F('fieldname4')) But instead of using the fieldnames directly, I would like to use a list with the field names: fields = ['fieldname1', 'fieldname2', 'fieldname4'] Depending on user interaction the number of fieldnames in the list can variate. Is there a way to do it? As this is my first question on StackOverflow, please let me know, if my question is unclear or I could improve my question. -
Rails or Django when you know Python well and Rails well but not Ruby nor Django
I know Rails well enough to build apps quickly (and have code I can reuse). But I don't know Ruby well (I realize the oddity). At the same time I do know Python well, having used it for data science. But I don't know much about Django. I want to build an app that is well beyond Django official tutorial difficulty (the polls app), and at the same time use cutting-edge algorithms in ML and NLP (might use tensorflow). So if Rails, I'd need to use micro service or call python script. If you were in my shoes, which framework would you use? -

Is there any way to use social auth in Django for multiple user types?
As the title says, is there any way to use social auth in Django for multiple user types? With user types I mean that there will be Students, Doctors and Patients in my platform. from django.db import models from django.contrib.auth.models import AbstractUser class User(AbstractUser): is_doctor = models.BooleanField(default=False) is_student = models.BooleanField(default=False) is_patient = models.BooleanField(default=False) class Doctor(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE, primary_key=True) #TO DO - More attributes class Student(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE, primary_key=True) #TO DO - More attributes class Patient(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE, primary_key=True) #TO DO - More attributes I want to let all of them to register and login with their Google Account. I have been looking at internet and allauth-django documentation, but I could´nt find any relevant info for my issue. Thanks in advance! -
Django - 500 error after launch on elastic-beanstalk
Hello I am still pretty green with the whole web deployment thing so bear with me this is only my second deployment. I've run into an issue called "500 Internal Server Error" I checked the aws documentation and all it can give me is error is unknown. The code all ran before I launched using runserver and the server was running before I put the code in so I don't know where the issue could be.

CSRF Token error when attempting to post from CURL to an API endpoint I control. How do I write the request?
I have not utilized this part of Django before, but I have an endpoint which is giving me a 403 error and is telling me that my request needs a csrf token. I was trying to figure out how best to get this since I was attempting to set up a bunch of curl requests to handle some simple queries to the endpoint. Likewise, I was thinking to also use POSTman, but I was not sure where documentation is to handle these request. I have seen the cookie csrftoken, but when I was attempting to curl with it, it was still giving me a 403. thought it would looking something like this: curl -d @profilepicturev2.png -b "csrftoken=Ebfn2OlfhSwFjAEQdoQon7wUjbynFoJqrtHMNPla3cy7ZfCMT9cxZ3OQHsbaedam" http://127.0.0.1:8000/api/files/uploader Maybe I am mistaken? -
Rest API schema to retrieve value from database and return
I need to make a Rest API which will take 3 inputs: input_list (list of srings sentences), from_lang (string), to_lang (string) and return list of string after fetching values from databse table. Example: input - {input_list: ['how are you', 'see you later', 'where are you'], from_lang: 'english', to_lang: 'spanish' } output - {['cómo estás', 'nos vemos más tarde', 'Dónde estás']} A service will call this API with list of sentences in any supported language, and in return they will get list of same length with translated sentence if it exist in database or null value if it doesn't exist. How should I proceed? What I have done is, I have created a serializer to handle/validate incoming request in serializers.py: def supported_lang(value): if value not in SUPPORTED_LANGUAGES: print(value) print(SUPPORTED_LANGUAGES) raise serializers.ValidationError('Language not supported') class TranslateSerializer(serializers.Serializer): input_list = serializers.ListField( child=serializers.CharField(allow_blank=False), allow_empty=False ) from_language = serializers.CharField(validators=[supported_lang]) to_language = serializers.CharField(validators=[supported_lang]) And I have defined a simple model for storing translations in model.py: class TranslationModel(models.Model): english = models.CharField(blank=False, max_length=MAX_LENGTH, unique=True) spanish = models.CharField(blank=True, max_length=MAX_LENGTH) italian = models.CharField(blank=True, max_length=MAX_LENGTH) is_active = models.BooleanField(default=True) Then in my views.py I have handled post requests like below class TranslateView(views.APIView): def post(self, request): serializer = TranslateSerializer(data=request.data) serializer.is_valid(raise_exception=True) serialized_data = serializer.validated_data result … -
In Django FileField, how to set file.name that contains also random url?
I am trying to modify the name of an uploaded file to include also some url in it. In my case it's the custom "file_url" variable. However the current result is: , but the expected result should be: http://www.google.com/ Here is my View.py: class CreateImage(CreateAPIView): permission_classes = (IsAuthenticated,) model = models.Image serializer_class = serializers.ImageSerializer def get_serializer(self, container, *args, **kwargs): serializer_class = self.get_serializer_class() kwargs["context"] = self.get_serializer_context() old_filename = self.request.FILES['image'].name if self.request.FILES: if container == 'products': data = self.request.data.copy() product_name = data["product_name"] file_url = f"{settings.MEDIA_DOMAIN}{container}/" new_filename = get_product_new_filename(old_filename, product_name) data['image'].name = file_url + new_filename kwargs["data"] = data return serializer_class(*args, **kwargs) And simple model for reference: class Image(models.Model): image = models.FileField() def __str__(self): return self.image.name Do you have any idea, how to include given url in the filename? The workaround, would be to create additional field, say image_url as CharField, and save it there, but maybe there is a way to not duplicate table inputs. Thanks in advance! -

Django Bootstrap modal carousel
Hello I am trying to create simple gallery and one of the feature I would like to add is modal window with carousel in it. For a backend I am using Django framework. And its current state it is partially working. If I click on image, the modal window opens but it show the 1st image on the site even though I click on any other image, it still shows the first image. Second issue is that the controls of the carousel do not work on any side and it keeps showing only 1st image and I am not able to see on any other.

Set a Model default value relative to another field
I'm building an auctions site and I want the highest_bid on a listing to be >= start_price and in turn set the bid_input to raise a ValidationError if a user tries to enter a bid_input < highest_bid. I don't want the user to have to enter a highest_bid when creating the form so I've set it to hidden input but want to figure out how to capture this value. I think I may have worked out how to validate bid_input using clean(self) but I am unsure how to set the highest_bid default value to greater or equal to the start_price. Should this be done on the model or on the form on saving? I'm quite confused on how to go about this really. models.py class Listing(models.Model): class NewManager(models.Manager): def get_queryset(self): return super().get_queryset().filter(status='active') options = ( ('active', 'Active'), ('closed', 'Closed'), ) title = models.CharField(max_length=64) description = models.TextField(max_length=64) start_price = models.DecimalField(max_digits=9, decimal_places=2, validators=[MinValueValidator(0.99)]) image = models.URLField(max_length=200, blank=True) category = models.ForeignKey(Category, on_delete=models.CASCADE, related_name="listings") lister = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE, default=None, null=True, blank=True) date_added = models.DateTimeField(default=timezone.now) highest_bid = models.DecimalField(max_digits=9, decimal_places=2, default=None) status = models.CharField(max_length=10, choices=options, default="active") favourites = models.ManyToManyField(User, related_name="favourite", default=None, blank=True) objects = models.Manager() listingmanager = NewManager() def __str__(self): return f"{self.title} ({self.pk}, £{self.start_price}, {self.lister})" class … -
How does the "action" attribute work in a Django form?

Ive researched online but the examples i found did not fit this script. Thanks for any help in advance. -
Is there a way to know screen size in django template?

Attribute Error: 'tuple' object has no attribute 'values'
I have a basic API to reset the password, however, it seems to be throwing this error, despite "values", not appearing in my code altogether: views.py class PasswordResetNewPasswordAPIView(GenericAPIView): serializer_class = SetNewPasswordSerializer def patch(self, request): user = request.data serializer = SetNewPasswordSerializer(data=user) serializer.is_valid(raise_exception=True) return Response({ "message": "password reset"}, status=status.HTTP_200_OK ) serializers.py class SetNewPasswordSerializer(serializers.Serializer): password = serializers.CharField(max_length=50, write_only =True) token = serializers.CharField(write_only =True) uidb64 = serializers.CharField(max_length = 255, write_only =True) fields = ("password", "token", "uidb64",) def validate(self, attrs): try: password = attrs.get("password", "") token = attrs.get("token", "") uidb64 = attrs.get("uidb64", "") print(uidb64) id = force_str(urlsafe_base64_decode(uidb64)) print(id) user = Author.objects.get(id=id) if not PasswordResetTokenGenerator().check_token(user, token): raise AuthenticationFailed("Invalid Reset Parameter", 401) user.set_password(password) user.save() return user except Exception: raise AuthenticationFailed("Invalid Reset Parameter", 401) return super().validate(attrs) urls.py ... path('password-reset-setup/', PasswordResetNewPasswordAPIView.as_view(),name="password-reset-setup"), What could be the possible error? And how to I get around it?
