Polars Read Excel file from Form (ie. request.FILES.get('file'))
All the Polars examples show reading an Excel file from a path string. df = pl.read_excel("docs/assets/data/path.xlsx") But I am passing in the Excel file from a Django Form Post. file_name = request.FILES.get('file') df = pl.read_excel(file_name) I am getting a "InvalidParametersError". How do input the file to Polars from a HTML form? or do I somehow have to get the path from the request.FILES and use that? I am new to the whole Polars thing but very excited to try it. thank you. -

Django Diagnosis Data Not Appearing in Admin After Endpoint Execution
I am working on a Django project where I process mock patient data and save it to a DiagnosisResult model in the database (SQLite). The goal is for this data to appear in the Django admin interface, but after calling the endpoint, the data doesn't appear in the database or admin. By "mock," I mean fictional data (not testing framework mocks), which I pre-generated to avoid using real patient data. Hers is my Minimal Reproducible Example (In order: models.py, views.py, urls.py, sample JSON data, Dockerfile, docker-compose.yml): models.py from django.db import models class Subtype(models.Model): CATEGORY_CHOICES = [('Acute', 'Acute'), ('Chronic', 'Chronic')] category = models.CharField(max_length=20, choices=CATEGORY_CHOICES) name = models.CharField(max_length=100) def __str__(self): return self.name class DiagnosisResult(models.Model): patient_name = models.CharField(max_length=100) age = models.IntegerField() symptoms = models.TextField() # Comma-separated list of symptoms test_results = models.TextField() likely_diagnoses = models.ManyToManyField(Subtype) def __str__(self): return f"{self.patient_name} (Age: {self.age})" views.py import json from pathlib import Path from django.http import JsonResponse from .models import Subtype, DiagnosisResult # File paths IS_DOCKER = Path("/app").exists() # Check if running inside Docker MOCK_DATA_FILE = ( Path("/app/apps/diagnosis/mock_data/mock_diagnosis_inputs.json") if IS_DOCKER else Path(__file__).resolve().parent / "mock_data" / "mock_diagnosis_inputs.json" ) def process_and_save_mock_diagnoses(request): with open(MOCK_DATA_FILE, "r") as file: mock_data = json.load(file) results = [] for patient in mock_data: likely_subtypes = Subtype.objects.filter(category="Acute") diagnosis_result … -
Django display edited time only for edited comments

I tried changing the code to check if it displays date when dt_created==dt_updated and it actually didn't display the edited time for all comments, including the comments that were edited. I also tried using comment.edited and it also didn't display edited time for all comments. What is wrong with my code? -
How to call and process Confirmation popup from a service function without interrupting the transaction
In my Django project, the business logic is placed in the service layer. Views only perform the function of working with templates. I have a basic template with a form and select type fields on it. When any field is changed, the script sends an AJAX request to views. views accepts this request and passes the data to a service function that uses it to write to the DB. template -> views -> service -> model Now I need to make a function to call the Confirmation popup from service to confirm the data change, receive a response from the window and process it. I already have a modal window and a script that calls it when response.confirmation_dialog. I need a mechanism for calling this window from the service without interrupting the transaction. One of the implementation options was to send a response to template with a confirmation modal call. Clicking the confirm-button on it would again send an AJAX request to views with confirmation information. Then this information would be sent back to the service, which checked whether the confirmation was passed or not. However, even with one confirmation, it looks bad, and the service may need several checks … -

Extra "[]" characters appearing before login fields for django admin
On my Django admin login page I see extra "[]" before the username and password fields: and I really cannot figure out where they are coming from. I'm using Django v5.1.3 and I haven't made any extra customisations to the django admin, so it should only be loading the default CSS and JS that the admin site natively comes with. It happens on both Brave and Firefox browsers. I'd really like to get rid of these, but have no idea where to start... let me know if any extra code/settings would be helpful to figure out. Any help much appreciated. -

How would you ignore a trigger within another trigger with django-pgtrigger
I am updating tbla."field_2" from a trigger in tblb. Except tbla."field_2" is protected with a pgtrigger.ReadOnly trigger. This works without the pgtrigger.ReadOnly trigger in TblA. How would I do it and keep the pgtrigger.ReadOnly trigger on TblA.field_2? Model TblA(models.Model): field_1 = models.CharField(max_length=20) field_2 = models.PositiveIntegerField(default=0) class Meta: triggers = [ pgtrigger.ReadOnly( name='read_only_field_2', fields=['field_2'] ) ] class TblB(models.Model): field_a = models.ForeignKey(TblA, on_delete=models.SET_NULL) class Meta: pgtrigger.Trigger( func=pgtrigger.Func(''' IF (NEW."{columns[field_a]}" IS NOT NULL) THEN UPDATE "tbla" SET "tbla"."field_2" = "tbla"."field_2" + 1 WHERE "tbla"."id" = NEW.{columns[field_a]} END IF; RETURN NEW; ''') ), when=pgtrigger.Before, operation=pgtrigger.Insert, name='increment_tbla_field_2' ), I was thinking to mimic pgtrigger.ignore() functionality within the trigger by using set_config however I am not very familiar how persistent set_config is. Do I need to clean up at the end of the trigger? Is this doable? set_config('pgtrigger.ignore', '{myapp:pgtrigger_read_only_field_2_c8215,pgtrigger_read_only_field_2_c8215}', true) -

TypeError: 'type' object is not subscriptable with prefetch_related
I’m trying to return a specific queryset using prefetch_related to optimize future queries, but I’m encountering an issue. When I don’t specify a return type, the code works fine. However, I want to understand the actual return type and what’s happening when I specify the return type as QuerySet[ABCInstance]. Here’s the code I’m working with: def _fetch_abc_instances(self) -> QuerySet[ABCInstance]: # Prefetch related "cde_instances" to avoid N+1 query issues return self.xyz_instance.abc_instances.prefetch_related("cde_instances") In this case: xyz_instance has a one-to-many relationship with abc_instances. abc_instances has a one-to-many relationship with cde_instances. My current environment: Python 3.6.7 Django 2.0.2 I’m expecting the return type to be ABCInstance, but since the query involves prefetching related data, the actual return type is different. I’d like to understand what the actual return type is in this case. -

404: NOT_FOUND error on Vercel - Django deployment
I deployed a Django project on Vercel and it shows the deployment is successful. However, when I try to open the website, it shows the error: 404: NOT_FOUND Code: NOT_FOUND ID: lhr1:lhr1::6n29s-1732227821846-0cc9eddbb440 My Django project can be found in the following link: https://github.com/RailgunGLM/railgunglm-com I tried solving the problem by, as some solutions on stackoverflow suggested, inserting a vercel.json file and a build.sh file, adding the line app = application at the very end of wsgi.py, including .vercel.app in my ALLOWED_HOSTS in setting.py, and lastly, installed whitenoise. However, none of them seems to work. The application works normally in my local machine, but I'm not sure whether I made a mistake in one of these files. I would be really appreciated if there is a solution to fix this problem.
