Django get_or_create then update race condition
I have the following model: class UserProductBinding: product = models.ForeignKey(Product) user = models.ForeignKey(User) purchased = models.BooleanField(default=False) liked = models.BooleanField(default=False) class Meta(object): unique_together = ['product', 'user'] Now I need a function that makes a purchase of a product by a user, which should Get UserProductBinding with corresponsing user and product, or create one if it doesn't exist Make sure "purchased" field is False Set "purchased" to True and deduct money from user's balance I'm doing it with the following code: binding, created = UserProductBinding.objects.get_or_create(product=product, user=user) if binding.purchased: raise Error() with transaction.atomic(): binding.purchased = True user.money -= price binding.save() user.save() The problem is that I have a race condition in this code. If this function is called twice in separate threads within a short time period, there is a chance that "if binding.purchased:" check will return False for both threads, hence the function will do its job twice and user's money will be deducted twice as well. select_for_update doesn't work for me, because I need to create the binding if it doesn't exist. update_or_create doesn't work either because it doesn't make sure that "purchased" field is false before making an update. Looks like using get_or_create followed by select_for_update would do the trick, … -
Django-filters - FilterSet model ... does not match queryset model ... when using Proxy model
I have a proxy model ClientAsUser which has it's own ModelViewSet and now I'm trying to setup a FilterSet. The problem is that django-filters returns this error: FilterSet model <class 'clients.models.client.ClientAsUser'> does not match queryset model <class 'users.models.user.User'> ClientAsUser has it's own manager with get_queryset method that returns only users with role=='client' class ClientAsUserFilterSet(django_filters.FilterSet): class Meta: model = ClientAsUser fields = { 'client_profile__agent': ['in', 'exact'] } class ClientAsUserViewSet(UserViewSet): queryset = ClientAsUser.objects.all() http_method_names = ['get', 'post'] permission_classes = [IsAuthenticated] serializer_class = ClientAsUserSerializer filter_backends = [DjangoFilterBackend] filterset_class = ClientAsUserFilterSet How to make it work?

I am getting Proxy errors after deploying to pythonanywhere
I developed a web application that uses the Omdb API to import movie data into the database using json(), I have successfully deployed this project to PythonAnywhere, and the web app runs at first glance. However when I search a movie and then try to click on said movie to import to database and review, I get this error: "HTTPSConnectionPool(host='m.media-amazon.com', port=443): Max retries exceeded with url: /images/M/MV5BMTIwMzExNDEwN15BMl5BanBnXkFtZTYwODMxMzg2._V1_SX300.jpg (Caused by ProxyError('Cannot connect to proxy.', OSError('Tunnel connection failed: 403 Forbidden')))" Can anyone tell me what the problem is and how to solve this? Also to add, when I run the application on my local machine and host, it runs successfully without any error. So I am guessing the error is from deploying. -

HTML validation error message reveals correct value unintentionally
I am trying to use an HTML number input field to validate a one-time code a user has. The one-time code is a Django model attribute under the user model, with the user object passed into the HTML template. Currently it is set up as such: <input type="number" name="auth_code" value="" min="{{user.auth_code}}" max="{{user.auth_code}}" onchange="this.setCustomValidity('')" onkeypress="this.setCustomValidity('')" oninput="this.setCustomValidity('')" oninvalid="this.setCustomValidity('This authorization code is incorrect.')" required /> If the user's code is 100000, and I enter 100001, I get the oninvalid message (as expected). However, if I delete a digit (or the whole number), I get a message stating "The value must be user.authcode." Clearly I don't want this value shown. If I set any message in the onchange or oninput field other than ('') (i.e. ('Enter a code.')), I can't validate any code (correct or incorrect). I run into the "This authorization code is incorrect." message even when validating 100000. How can I get around this? -
How to make dynamic field serializer in Django RestFramework
I want to add Dynamic Field Array serializer in my drf project: My get response looks something like this: { "title": "some", "created_at": "2022-03-06T15:59:52.684469Z", "fields": [ { "id": 1, "title": "Some title?", "parent_field": 1 }, { "id": 2, "title": "Yet another fields", "parent_field": 1 } ] } This is the item detail serializer, and fields is another model serializer. I achieved this by using this code: class AnotherFieldSerializer(serializers.ModelSerializer): class Meta: model = AnotherModel fields = "__all__" class FirstSerializer(serializers.ModelSerializer): fields = serializers.SerializerMethodField() class Meta: model = FirstModel fields = "__all__" def get_fields(self, obj): serializer_context = {'request': self.context.get('request')} children = obj.fields if not children.exists(): return None serializered_children = FirstSerializer( children, many=True, context=serializer_context ) return serializered_children.data This works only for GET requests I want this to also work with POST and PUT requests. So, imagine I want to add/edit an item into my model FIRST model and add fields associated with it by just sending this JSON: { "title": "some", "created_at": "2022-03-06T15:59:52.684469Z", "fields": [ { "id": 1, "title": "Some title?", }, { "id": 2, "title": "Yet another fields", } ] } I know I can get fields from the response and loop through each item to create an instance of Another Model but … -

Cross domain cookie not being sent in the subsequent request even when it is set in the last response
I have my app at app.exampledomain.com which is in reactjs(axios for api call) and it is consuming api from api.exampledomain.com. in the response to an api call the server at api.exampledomain.com is setting the cookie in the response header like: sessionid=fyytiannsv29edvn4zgkr1orfcfscyh3; expires=Sat, 26 Mar 2022 14:02:49 GMT; HttpOnly; Max-Age=604800; Path=/ but in the subsequent requests from app.exampledomain.com the cookie is not being sent in the request header and again set cookie is received in the response header. moreover, the cookie that api sets is not visible in the cookies tab of the browser. I think the browser is rejecting the cookie sent by the server as both the client and server have different subdomains/sites (api.exampledomain.com vs app.exampledomain.com). I want to set cookies having sessionid and this sessionid to be sent in request headers cookies in subsequent requests from app to api. if i make SESSION_COOKIE_DOMAIN = '.example.com' i am able to see the cookie in the browser with domain '.exampledomain.com', still it is not being sent in the subsequent requests and new sessionid is being sent in set cookie in response headers. I tried modifying SESSION_COOKIE_SAMESITE, SESSION_COOKIE_SECURE but it did not help. -

Render DjangoCKEditor in React CKEditor
I would like to know whether it is possible to render RichTextField from Django CKEditor using CKEditor from ckeditor5-react ? As far as I know, we could manually render django field in anyway as long as the name and id is the same as the form field. But I have no idea how do I replicate Django CKEditor using React CKEditor. -
Model.Form Queryset
I have a model.form which I need to apply a queryset to filter the choices available within a select field. class AnswerForm(ModelForm): class Meta: model = ProjectQuestionnaireAnswer fields = ('answer','notes') widgets = { 'answer': forms.Select(choices = Choice.objects.filter(question_id = 1),attrs={'class': 'form-control select2'}), 'notes': forms.Textarea(attrs={'class': 'form-control','placeholder': 'Add notes to question here'}), } class Choice(models.Model): question = models.ForeignKey(ProjectQuestionnaireQuestion, on_delete=models.CASCADE) choice_text = models.CharField(max_length=200) def __str__(self): return str(self.choice_text) I'm not sure how to write the query to only return the choices related to the question. I've tested with choices = Choice.objects.filter(question_id = 1) which does return me the choices for question 1, but need it for each question? And then how do I present this in my template? {{ form.answer.choices }} ?? Thanks -
How to get table data (including child table and sub child data) based on id which obtains from another table data? Django
views company = Company.objects.get(id = company_id) # getting input from django urls (<int:company_id>) vehicles = CompanyContainVehicles.objects.filter(company_id=company.id) # Give all rows having same id (company.id) all_vehicles = Vehicle.objects.filter(companies=company) # Gives all row with id provide by company all_vehicles_parts = VehiclePart.objects.filter(__________) # Not Working models class Company(models.Model): name = models.CharField(max_length=255) slug = models.SlugField(blank=True, null=True, unique=True) description = models.TextField() class Vehicle(models.Model): vehicle_number = models.IntegerField() name = models.CharField(max_length=255) slug = models.SlugField(blank=True, null=True, unique=True) companies = models.ManyToManyField( Company, through='CompanyVehicle', related_name='companies' ) class CompanyVehicle(models.Model): company = models.ForeignKey(Company, on_delete=models.CASCADE) vehicle = models.ForeignKey(Vehicle, on_delete=models.CASCADE) created_at = models.DateTimeField(auto_now_add=True) class VehiclePart(models.Model): id = models.AutoField(primary_key=True) vehicle = models.ForeignKey(Vehicle, on_delete=models.CASCADE) type = models.ForeignKey(PartType, on_delete=models.CASCADE) created_at = models.DateTimeField(auto_now_add=True, blank=True) How do I get VehiclePart's with their Vehicle? (I think I will give all the data in a variable and we should divide it and add it with their Vehicle). Also, what can we do to access data if VehiclePart contains a child class named VehiclePartDetail? -
Unable to fetch model data in Django Async conusmers . working in channels and websockets
I am working on a chat application with channels and websockets using async programming. I am unable to get the model data / object in consumers.py but able to create one .

Not all files called with django static appear
I have index.html file in template file and I have js, css, image, files in my static file. I am writing the codes correctly, but the site does not appear properly. Animations, images and text are not in the correct place. (In fact, the logo of the project I used to work with appears in this project. Both are called "logo.png", I think pycharm is confusing the codes. But I opened my project with Visual Studio Code, and the logo of my old project appeared again. Why is this happening? Do I need to delete something?) settings.py STATIC_URL = 'static/' STATICFILES_DIRS = [os.path.join(BASE_DIR, 'static')] index.html <!DOCTYPE html> {% load static %} <html lang="en"> <!-- Basic --> <head> <link rel="shortcut icon" href="{% static 'images/favicon.ico' %}" type="image/x-icon"> <link rel="apple-touch-icon" href="{% static 'images/apple-touch-icon.png' %}"> <!-- Bootstrap CSS --> <link rel="stylesheet" href="{% static 'css/bootstrap.min.css' %}"> <!-- Site CSS --> <link rel="stylesheet" href="{% static 'css/style.css' %}"> <!-- Responsive CSS --> <link rel="stylesheet" href="{% static 'css/responsive.css' %}"> <!-- Custom CSS --> <link rel="stylesheet" href="{% static 'css/custom.css' %}"> <!--[if lt IE 9]> <script src="https://oss.maxcdn.com/libs/html5shiv/3.7.0/html5shiv.js"></script> <script src="https://oss.maxcdn.com/libs/respond.js/1.4.2/respond.min.js"></script> <![endif]--> </head> <body> <!-- ALL JS FILES --> <script src="{% static 'js/jquery-3.2.1.min.js' %}"></script> <script src="{% static 'js/popper.min.js' %}"></script> <script src="{% static …
