How to properly update the foreign key's property of a Django model?
I have a Django Model named EmailSendingTask. This is the whole model- class EmailSendingTask(models.Model): order = models.OneToOneField(Order, on_delete=models.CASCADE, related_name='order') status = EnumChoiceField(SetupStatus, default=SetupStatus.active) time_interval = EnumChoiceField(TimeInterval, default=TimeInterval.five_mins) immediate_email = models.OneToOneField(PeriodicTask, on_delete=models.CASCADE, null=True, blank=True, related_name='immediate_email') scheduled_email = models.OneToOneField(PeriodicTask, on_delete=models.CASCADE, null=True, blank=True, related_name='scheduled_email') created_at = models.DateTimeField(auto_now_add=True) class Meta: verbose_name = 'EmailSendingTask' verbose_name_plural = 'EmailSendingTasks' def __str__(self) -> str: return f'EmailSendingTask: Order = {self.order}' The immediate_email and scheduled_email fields are responsible for holding two PeriodicTask objects. I have created a function called disable_scheduled_email, which is responsible for disabling the scheduled_email's periodic task. The detail of the function is here- def disable_scheduled_email(self): print(f'Disabling scheduled email...') self.scheduled_email.enabled = False self.save(update_fields=['scheduled_email']) Now, whenever I call this function and print the value of the self.scheduled_email.enabled, I find it False. But, when I try to look at the Django Admin site, the periodic task's enabled value remains as True. Why is it happening? -
When to make stripe subscription object and assign to user - Django
Tech Stack - Django, Angular I have been implementing stripe subscription model but stuck at some absurd scenario. I am getting Subscription not found by django. Please read the full scenario. Firstly I am successfull in creating stripe session. Code session = stripe.checkout.Session.create( metadata={'price_id':request.data.get('price_id'),'product_id':request.data.get('product_id'),'product_name':request.data.get('product_name')}, client_reference_id=request.user.id, customer=customer.stripe_customer_id, success_url='http://localhost:4200/success?session_id={CHECKOUT_SESSION_ID}', cancel_url='http://localhost:4200/canceled.html', mode='subscription', line_items=[{ 'price': request.data['price_id'], # For metered billing, do not pass quantity 'quantity': 1, }], ) Webhooks Implementation: checkout.session.completed I am creating customer and subscription model in my db. print(user) customer = RecruiterUserProfile.objects.get(user = user) print(customer) customer.customer_id = session.customer customer.save() stripecustomer = Customer.objects.get(recruiter = customer, checkout_session_id = stripe_session_id) print(stripecustomer) stripecustomer.stripe_customer_id = stripe_customer_id stripecustomer.save() subscription,created = Subscriptions.objects.get_or_create(recruiter = customer, sub_id=stripe_subscription_id,customer_id = stripecustomer,stripe_customer_id = stripe_customer_id, payment_status=stripe_payment_status, amount = stripe_amount, status = stripe_status, product_id = stripe_metadata['product_id'], price_id = stripe_metadata['price_id'], product_name = stripe_metadata['product_name']) invoice.paid Then it triggers Invoice.paid, in which I am getting the subscription model and update others values in it. But since webhooks do not wait for our calls, Sometimes, It doesn't find the subscription. Now if I create subscription and customer in invoice.paid webhook using ger_or_create, How am I supposed to link it to the user. Below are my models: class Customer(models.Model): recruiter = models.OneToOneField(RecruiterUserProfile, on_delete=models.PROTECT) stripe_customer_id = models.CharField(max_length=80, blank=True, null=True) checkout_session_id = … -
How to pass current logged in users pk in django URLs?

In Django, what's the difference between verbose_name as a field parameter, and verbose_name in a Meta inner class?
Consider this class: class Product(models.Model): name = models.Charfield(verbose_name="Product Name", max_length=255) class Meta: verbose_name = "Product Name" I looked at the Django docs and it says: For verbose_name in a field declaration: "A human-readable name for the field." For verbose_name in a Meta declaration: "A human-readable name for the object, singular". When would I see either verbose_name manifest at runtime? In a form render? In Django admin? -

Spider in Django views
I want to use scrapy spider in Django views and I tried using CrawlRunner and CrawlProcess but there are problems, views are synced and further crawler does not return a response directly I tried a few ways: # Core imports. from scrapy.crawler import CrawlerProcess from scrapy.utils.project import get_project_settings # Third-party imports. from rest_framework.views import APIView from rest_framework.response import Response # Local imports. from lrn_scrap.spiders.google import GoogleSpider class ForFunAPIView(APIView): def get(self, \*args, \*\*kwargs): process = CrawlerProcess(get_project_settings()) process.crawl(GoogleSpider) process.start() return Response('ok') is there any solution to handle that and run spider directly in other scripts or projects without using DjangoItem pipeline? -
How can I do authentication on the site and the built-in Users model and my own Employer Django
Happy New Year! I ran into a problem I am making a job search site on Django, I have the following logic: Authorization and authentication of ordinary job seekers using Django's built-in model - User Also separate authorization and authentication for users who provide work, i.e. employers, which are placed in my own model Employer Here is my Employer model class Employer(AbstractUser): full_name = models.CharField(max_length=150, verbose_name="Ім'я") main_office_city = models.ForeignKey(City, on_delete=models.CASCADE, verbose_name='Місто головного офісу') phone_number = models.ForeignKey(Phone, on_delete=models.CASCADE) email = models.CharField(max_length=50, unique=True, verbose_name='Email') hashed_password = models.CharField(max_length=120, default='') date_joined = models.DateTimeField(verbose_name='Дата реєстрації', default=timezone.now) def __str__(self): return self.full_name class Meta: verbose_name = 'Роботодавець' verbose_name_plural = 'Роботодавці' I read in the documentation that to create your own authentication system you can use the imitation from the AbstractUser class But in my case this is not the best choice, because AbstractModel adds its own fields by default. That is, I think that I need to either somehow make it so that the AbstractUser class does not add its fields, or think of some other authentication logic using another technology Maybe someone has some ideas how it can be done? -

Here's the model class Document(models.Model): file = models.FileField() The template {% extends 'another-form.html' %} {% block content %} <form enctype="multipart/form-data" method="post"> {% csrf_token %} {% bootstrap_field form.files %} <button class="btn btn-success col">Upload</button> </form> {% endblock %} Form class and view: from django import forms from django.urls import reverse_lazy from django.views.generic import FormView class UploadDocumentForm(forms.Form): files = forms.FileField(widget=forms.FileInput(attrs={'multiple': True}), label='') class UploadDocumentView(FormView): template_name = 'upload-document.html' form_class = UploadDocumentForm success_url = reverse_lazy('index') def form_valid(self, form): Document.objects.bulk_create([Document(file=f) for f in self.request.FILES]) return super().form_valid(form) when the form is submitted, I get these responses: [02/Jan/2023 14:43:13] "POST /upload-document/ HTTP/1.1" 302 0 [02/Jan/2023 14:43:14] "GET /upload-document/ HTTP/1.1" 200 70636 [02/Jan/2023 14:43:17] "GET /upload-document/ HTTP/1.1" 200 70635 and nothing is uploaded to settings.MEDIA_ROOT which is specified in settings.py and works for models.ImageField.

Creating a django form dynamically from a database model
I am trying do dynamically build a Questionnaire with its Questions and answers based on the information stored in a database. Database model: class Questionnaire(models.Model): name = models.CharField(max_length=200) def __str__(self): return self.name class Question(models.Model): questionnaire = models.ForeignKey(Questionnaire, on_delete=models.CASCADE) sequence = models.PositiveSmallIntegerField() text = models.CharField(max_length=200) created_at = models.DateTimeField(auto_now_add=True) updated_at = models.DateTimeField(auto_now=True) def __str__(self): return self.text class QuestionAnswer(models.Model): question = models.ForeignKey(Question, on_delete=models.CASCADE) text = models.CharField(max_length=200) points = models.PositiveSmallIntegerField() created_at = models.DateTimeField(auto_now_add=True) updated_at = models.DateTimeField(auto_now=True) def __str__(self): return self.text I am trying to get a Form, that - based on a Questionnaire id passed to a view would render all Questions with their Questionanswers (as radio buttons). I started to design a Form that displays all the answers for a specific Question, if the question_id gets handed to a form: class QAForm(forms.Form): answer = forms.ModelChoiceField(widget=forms.RadioSelect, queryset=QuestionAnswer.objects.none()) def __init__(self, *args, question_id=None, **kwargs): super().__init__(*args, **kwargs) if question_id is not None: print(question_id) self.fields['answer'].queryset = QuestionAnswer.objects.filter(question=question_id) This works, but I struggle to build a formset of QAForms that would cycle through the question_ids and show their answers for the user. I found https://forum.djangoproject.com/t/pass-different-parameters-to-each-form-in-formset/4040/2 - which seems to handle dynamic parameters to the formset forms. At this time though, i am starting to think that such solution is … -

How to capture Django CSFR Cookie in Postman?
I am trying to send my first POST request that isn't handled inside Django to my Django server. I read in several tutorials from 3 years ago that I should somehow see the CSFR token value in the cookie, eg.: https://hackernoon.com/automatically-set-csrf-token-in-postman-django-tips-c9ec8eb9eb5b I cannot achieve that and I have problems finding tutorials on how to capture that cookie to use it later. Please help.
