How to do aggregate raw sql with julian date in sqlite (with django)
I'm using sqlite3 and django. I wish to calculate the average for all the number of days between last_played and now. (Last_played is just a datetime field). I have so far: avg_days_last_played_sql = """ AVG(julianday('now') - julianday(played_at)) """ # Annotate the average days last played average_days_last_played = Song.objects.aggregate( avg_days_last_played=RawSQL(avg_days_last_played_sql, []) )['avg_days_last_played'] But it gives the error: TypeError: avg_days_last_played is not an aggregate expression -

Rename my Django auth app to fix the "Application labels aren't unique" error
When I created my Django project I created an app called auth. I never used django.contrib.auth, instead I rolled my own authentication code. A User model without a password field, custom API views and serializes, login goes via magic links sent to email, etc. I didn't use the Django Admin so I never needed Django's auth implementation. Now I do want to add the Django Admin to my project, and for that I need to add django.contrib.auth and now I am running into some big problems because of the error django.core.exceptions.ImproperlyConfigured: Application labels aren't unique, duplicates: auth. Renaming my own auth app doesn't seem possible. I tried to change the label in its AppConfig but existing migrations are breaking in all sorts of fun and exiting ways. So I thought I'd import Django's auth app with a custom label, like so: # djangoauth.py from django.apps import AppConfig class DjangoAuthConfig(AppConfig): name = "django.contrib.auth" label = "django_auth" And then I added djangoauth.DjangoAuthConfig to INSTALLED_APPS. But that also doesn't work, as Django's auth app has migrations with the auth name being hardcoded, so changing the app label now breaks those migrations. I don't really know how to fix this problem. I really wish … -

Handling Multiple User Inputs in Custom Django Form Field: Processing All Values
I am working on creating a custom form field in Django where users can input multiple text values dynamically at the frontend. However, I'm facing an issue where only the last text input value is being processed in the to_python method of the field, even though I can see all the input values in the Request.POST.

Quill Rich Text Editor Not Submitting Content on First Click
I am using Quill's Rich Text Editor in my Django web application and I am facing an issue where the content from the editor is not being sent to the server upon the first form submission (first click of the submit button), but only sends after the second form submission (second click of the submit button).

How to Access Checkout Session Metadata in Stripe Webhook for Payment Methods in Subscription Mode
I'm integrating Stripe Checkout in a Django application and handling webhooks to update user information based on payment events. However, I'm encountering issues accessing metadata associated with a Checkout Session when dealing with payment_method objects. Context: I have the following setup for Stripe Checkout: StripeCheckoutMonthlyView and StripeCheckoutYearlyView: Both create a Checkout Session with metadata (e.g., user_id, plan_type). Webhook Handler (stripe_webhook): Processes different event types from Stripe. Problem: In the payment_method.attached event, I need to access metadata that was included in the Checkout Session. However, the payment_method object does not include metadata and does not directly reference the Checkout Session. Here’s how my webhook handler looks: @csrf_exempt def stripe_webhook(request): payload = request.body event = None print('Stripe Webhook Received!') try: event = stripe.Event.construct_from( json.loads(payload), stripe.api_key ) except ValueError as e: # Invalid payload return HttpResponse(status=400) if event.type == 'payment_intent.succeeded': # Handle payment_intent.succeeded event pass elif event.type == 'payment_method.attached': payment_method = event.data.object # Issue: Payment method does not include metadata or session_id pass elif event.type == 'checkout.session.completed': session = event.data.object # Retrieve session metadata here pass else: print('Unhandled event type {}'.format(event.type)) return HttpResponse(status=200) What I Need: I need to update user information based on metadata that was included in the Checkout Session.

I have a recycle bin model in my Django project that works fine with other models since I have overidden the delete function to soft delete any model object by using is_deleted=True in every model. class RecycleBin(models.Model): title = models.CharField( max_length=1000, verbose_name="Title", null=False, blank=False, ) content_type = models.ForeignKey(ContentType, on_delete=models.CASCADE) object_id = models.PositiveIntegerField() deleted_object = GenericForeignKey("content_type", "object_id") deleted_by = models.ForeignKey( "Accounts.User", verbose_name="Deleted By", on_delete=models.CASCADE, blank=False, null=False, related_name="deleted_by", ) tenant = models.ForeignKey( "Tenants.Tenant", verbose_name="Tenant", max_length=1000, null=False, blank=False, on_delete=models.CASCADE, ) date_deleted = models.DateTimeField(verbose_name="Date Deleted", auto_now_add=True) due_deletion_date = models.DateTimeField(verbose_name="Due Deletion", default=None, null=True, editable=False) However, in my Files model, when i try to delete a file, i get an error RecycleBin() got unexpected keyword arguments: 'title', 'content_type', 'object_id', 'deleted_by'. class AllFilesManager(models.Manager): def get_queryset(self): return super().get_queryset() class ActiveFileModelManager(models.Manager): def get_queryset(self): return super().get_queryset().filter(is_deleted=False) class File(models.Model): uuid = models.UUIDField(default=uuid.uuid4, editable=False, unique=True) name = models.CharField(max_length=1000, null=False, blank=False) folder = models.ForeignKey( "Folders.Folder", on_delete=models.CASCADE, null=False, blank=False ) file = models.FileField( upload_to='tenants', storage=storage, max_length=1000, null=False, blank=False ) is_deleted = models.BooleanField(default=False, verbose_name="Is Deleted?") created_by = models.ForeignKey( "Accounts.User", verbose_name="Created By", on_delete=models.CASCADE, blank=False, null=False, related_name="file_created_by", ) modified_by = models.ForeignKey( "Accounts.User", verbose_name="Modified By", on_delete=models.CASCADE, blank=True, null=True, related_name="file_modified_by", ) tenant = models.ForeignKey( "Tenants.Tenant", verbose_name="Tenant", max_length=1000, on_delete=models.CASCADE, null=False, blank=False, ) date_created = models.DateTimeField(verbose_name="Date Created", auto_now_add=True) date_modified = models.DateTimeField(verbose_name="Date … -

"PostgreSQL 12 or later is required (found 10.23)" Django error while connecting to PostgreSQL 16
Exception Type: NotSupportedError Exception Value: PostgreSQL 12 or later is required (found 10.23). The above exception is thrown by the db backend. The obvious assumption would a mismatch of versions; it isn't the case as I have made certain of this. The connection is to a remote db running on v16. Indeed, I have even migrated services but to no avail just to make sure. Also, it a bit imprecise as I was able to migrate, createsuperuser and create some objects from admins before the error was thrown again. settings/init.py: import os if os.environ.get("ENV_NAME") == 'production': from .production import * elif os.environ.get("ENV_NAME") == 'staging': from .staging import * else: from .base import * settings/base.py (contains base settings) import os from pathlib import Path import environ import dj_database_url env = environ.Env() # Take environment variables from .env file environ.Env.read_env() # Build paths inside the project like this: BASE_DIR / 'subdir'.

Need suggestions on getting data from odoo inside Django on user navigation
I am developing a Complaint Management System with the admin side in Odoo and the subscriber side in Django. All complaints and subscriber information are managed on the admin/Odoo side, while the Django side is used solely for subscriber registration and recording of complaints. I need suggestions on what technology or methodology to use to retrieve subscriber information from Odoo when a subscriber logs in. There are various links where subscribers can click to view their information, which is retrieved from Odoo. These options are coming in my mind XML-RPC read ().The simplest option is to read specific form data from Odoo and display it in a Django form when users click on certain links. Django Channels Observable. I Appreciate clear guidance which technology stack I should use. -
Django session is not maintained on browser. login_required decorator is redirecting to login page
Background: I made a custom user model in django with Custom backend implementing authenticate and get_user methods. its all working fine with the requests and the user objects and stuff, but when i tried to use login_required for a view, it sends the page back to login page. the user is being authenticated and all the stuff is happening. but login is not being maintained on the browser Github Link: https://github.com/WarLoRDlArS/Prodvi Login View: view is located in Prodvi/users/views.py def login_page(request): if request.method == "POST": pid = request.POST.get("pid") password = request.POST.get("password") if not Users.objects.filter(pid=pid).exists(): messages.error(request, 'Invalid Username') return redirect('users:login') user = authenticate(request, pid=pid, password=password) if user is None: messages.error(request, 'Invalid Credentials') return redirect('users:login') print("User is None") login(request, user) print("Login Successful") # Login is a success return redirect('home:index') # Test Login # pid: 000000 # password: abc return render(request, 'users/login.html') Index page code: index is located in Prodvi/home/views.py @login_required(login_url='users:login') def index(request): print("came here") return HttpResponse('Welcome To Prodvi') i tried with various stuff like changing session timeout, setting session_cookie_secure, debugging using print statements. when i remove login_require, it works but otherwise it doesnt. -
I'm having troubles migrating my company's data from Magento to Django Rest Framework
I observed that the SQL tables were not organised enough for a typical migration, so I decided to work on a new lighter DB and utilise Django because of its stability to handle the seeding of the new DB from the Magento DB through the API it provides. The major tables I need for the new DB are: Products Categories Brands Customer Details I have a script that successfully seeds categories and brands. I am yet to attempt Customer Details, and the major issue is that the products have images attached to them, and I am not sure how to do the migrations of images effectively. Also the categories are forgetting their parent category, reason is since they are all creating at the same time, the parent category ID will always return not found. I created some scripts already, seed categories and seed brands fully functional. I created another sript to run all the necessary migrations too. #!/bin/bash set -e GREEN='\033[0;32m' RED='\033[0;31m' RESET='\033[0m' GAP="\n\n\n" echo "Installing requirements..." pip install -r requirements.txt echo -e "${GREEN}Requirements installed!${RESET}${GAP}" echo "Migrating database..." python manage.py makemigrations python manage.py makemigrations helpers api python manage.py migrate echo -e "${GREEN}Migration complete!${RESET}${GAP}" echo "Seeding Image..." python manage.py seed_image echo … -
Django queryset stops working after multiple uses and filters
I am currently working on a task which requires me to divide my model data into multiple parts based on conditions and then process them differently. I am able to get data from my model correctly and check all available details that they exists. But after applying certain number of filters, suddenly the queryset stops working and don't give the correct results. I don't know why this is happening, can someone explain? Here is part of my code that is causing issue: def test_selection(): po_numbers = ( Model1.objects .filter(schedule__isnull=True) .filter(order_hold_type__isnull=True) .filter(so_line_status='Awaiting Supply') .values_list("customer_po", flat=True) .distinct() ) rows = Model1.objects.filter(customer_po__in=po_numbers).annotate( total_qty=Sum(F('line_item_quantity')*F('cup_count')) ).all() old_sizes = Sizes.get_old_sizes() old_po = rows.filter( item_size__in=old_sizes).values_list('customer_po', flat=True).distinct() rows = rows.filter(~Q(customer_po__in=old_po)).all() partially_scheduled = rows.filter( customer_po__in=list(rows.filter(schedule__isnull=False).values_list( 'customer_po', flat=True).distinct()) ).all() unscheduled = rows.filter( ~Q(customer_po__in=list(partially_scheduled.values_list( 'customer_po', flat=True).distinct().all())) ).all() model2_po = Model2.objects.values_list('customer_po', flat=True).distinct() g1 = unscheduled.exclude(customer_po__in=model2_po) po_list = g1.values_list('customer_po', flat=True).distinct() print(rows.count(), po_list) I thought the problem is in my flow so I created a separate function to test this and this is the point after which the problem starts occurring. This is not throwing any error but coming up empty and I have tried searching for anyone having similar issue but cannot find anything. I have tried following things uptil now: Use filter(~Q()) …
