How can I eliminate the segfaults that occur in working code only when debugging with ipdb?
I am using: Python: 3.11.0 Django: 4.2.8 djangorestframework 3.14.0 sqlite: 3.38.5 When I'm debugging and I use 'n' to go over a method, I sometimes get a segfault where there is no problem running the code normally. I can move my 'ipdb.set_trace()' to immediately after the call that caused the segfault, rerun the test and continue debugging but this is tedious. One cause I've tracked, is under the django reverse function. Here, the <URLResolver <module 'rest_framework.urls' from '/home/paul/wk/cliosoft/sosmgrweb/venv/lib/python3.11/site-packages/rest_framework/urls.py'> (rest_framework:rest_framework) 'api-auth/'> causes the segfault when its _populate method is invoked. I could start upgrading everything but this is a large application with many dependencies and I'd like to be confident that this problem will be eliminated if I go down that road. Does anyone know what the cause of this is and how I can resolve it? -

Why is my stopwatch adding fixed amount of time when I refresh?
I have a Vue.js Script is Adding time to my stopwatch once I refresh the page - Always adds an additional 6 hours. The script is simply a button that tracks time when clicked, and post the time to a django model once stopped. I am able to track time fine, but when I refresh the page, I come back to seeing 6 hours added to my stopwatch: Vue.js Script: var NavbarApp = { data() { return { seconds: {{ active_entry_seconds }}, trackingTime: false, showTrackingModal: false, timer: null, entryID: 0, startTime: '{{ start_time }}' } }, delimiters: ['[[', ']]'], methods: { startTimer() { fetch('/apps/api/start_timer/', { method: 'POST', headers: { 'Content-Type': 'application/json', 'X-CSRFToken': '{{ csrf_token }}' } }) .then((response) => { return response.json() }) .then((result) => { this.startTime = new Date() this.trackingTime = true this.timer = setInterval(() => { this.seconds = (new Date() - this.startTime) / 1000 }, 1000) }) }, stopTimer() { fetch('/apps/api/stop_timer/', { method: 'POST', headers: { 'Content-Type': 'application/json', 'X-CSRFToken': '{{ csrf_token }}' } }) .then((response) => { return response.json() }) .then((result) => { this.entryID = result.entryID this.showTrackingModal = true this.trackingTime = false window.clearTimeout(this.timer) }) }, discardTimer() { fetch('/apps/api/discard_timer/', { method: 'POST', headers: { 'Content-Type': 'application/json', 'X-CSRFToken': '{{ csrf_token … -
How to Efficiently Create and Maintain SQL Indexes in Django with PostGIS?
I'm working on a Django project that utilizes PostGIS for spatial data. Currently, I'm considering creating a SQL index for the created_at field to improve query performance. The created_at field is configured with auto_now_add=True, meaning it automatically captures the timestamp when an object is created. However, I'm unsure about the best practices for creating and maintaining SQL indexes in Django with PostGIS. Here are my specific questions: What is the recommended approach for creating SQL indexes in Django with PostGIS? Does creating an index for the created_at field significantly improve querying performance in Django? What are the potential maintenance tasks associated with managing SQL indexes in Django with PostGIS? I would appreciate any insights, advice, or best practices from experienced Django developers or those familiar with working with PostGIS. Thank you! -
Django: Mocking an external api call in the save method of a model
I want to test a modelform using pytest in two modes: without the need to call the external API used in the save method by generating an error when the API is offline so I can test the validation I created Here's my code: trips/models.py class Place(models.Model): trip = models.ForeignKey(Trip, on_delete=models.CASCADE, related_name="places") day = models.ForeignKey( Day, on_delete=models.SET_NULL, null=True, related_name="places" ) name = models.CharField(max_length=100) url = models.URLField(null=True, blank=True) address = models.CharField(max_length=200) latitude = models.FloatField(null=True, blank=True) longitude = models.FloatField(null=True, blank=True) objects = models.Manager() na_objects = NotAssignedManager() def save(self, *args, **kwargs): old = type(self).objects.get(pk=self.pk) if self.pk else None # if address is not changed, don't update coordinates if old and old.address == self.address: return super().save(*args, **kwargs) g = geocoder.mapbox(self.address, access_token=settings.MAPBOX_ACCESS_TOKEN) self.latitude, self.longitude = g.latlng return super().save(*args, **kwargs) def __str__(self) -> str: return self.name trips/forms.py class PlaceForm(forms.ModelForm): class Meta: model = Place fields = ["name", "url", "address", "day"] formfield_callback = urlfields_assume_https widgets = { "name": forms.TextInput(attrs={"placeholder": "name"}), "url": forms.URLInput(attrs={"placeholder": "URL"}), "address": forms.TextInput(attrs={"placeholder": "address"}), "day": forms.Select(attrs={"class": "form-select"}), } labels = { "name": "Name", "url": "URL", "address": "Address", "day": "Day", } def __init__(self, *args, parent=False, **kwargs): super().__init__(*args, **kwargs) if parent: trip = parent else: trip = self.instance.trip self.fields["day"].choices = ( Day.objects.filter(trip=trip) .annotate( formatted_choice=Concat( "date", Value(" (Day … -
Cant get Django Date Widget to show in form
I am attempting to get a date field in a form to display as a date with date picker. For some reason, the field will not display as a date type. The model field: registration_date = models.DateField(null=True, blank=True) The form: class VehicleQuickAdd(forms.ModelForm): class Meta: model = Vehicle fields = ['license_plate', 'internal_id', 'affiliated_company', 'registration_date', 'active_since', 'registration_certificate',] widgets = { 'registration_date': forms.DateInput(attrs={'type': 'date'}) } The HTML: {% extends 'base.html' %} {% load crispy_forms_tags %} {% block title %}Add Vehicle{% endblock title %} {% block content %} <div class="section-container container-fluid"> <div class="general-form pl-md-5 pr-md-5"> <h2>Add Vehicle</h2> <form action="" method="post"> {% csrf_token %} {% crispy form %} </br> <input class="btn btn-success" type="submit" value="save"> </form> </div> </div> {% endblock content %} When I look at the element in the page it says type="text" <input type="text" name="registration_date" class="dateinput form-control" id="id_registration_date"> Any ideas about why this isn't working? -
Annotations returning pure PK value instead of Django HashID
In my application the user can assume one of 3 different roles. These users can be assigned to programs, and they can be assigned to 3 different fields, each of those exclusevely to a role. In my API I'm trying to query all my users and annotate the programs they are in: def get_queryset(self): queryset = ( User.objects .select_related('profile') .prefetch_related('managed_programs', 'supervised_programs', 'case_managed_programs') .annotate( programs=Case( When( role=RoleChoices.PROGRAM_MANAGER, then=ArraySubquery( Program.objects.filter(program_managers=OuterRef('pk'), is_active=True) .values('id', 'name') .annotate( data=Func( Value('{"id": '), F('id'), Value(', "name": "'), F('name'), Value('"}'), function='concat', output_field=CharField(), ) ) .values('data') ), ), When( role=RoleChoices.SUPERVISOR, then=ArraySubquery( Program.objects.filter(supervisors=OuterRef('pk'), is_active=True) .values('id', 'name') .annotate( data=Func( Value('{"id": '), F('id'), Value(', "name": "'), F('name'), Value('"}'), function='concat', output_field=CharField(), ) ) .values('data') ), ), When( role=RoleChoices.CASE_MANAGER, then=ArraySubquery( Program.objects.filter(case_managers=OuterRef('pk'), is_active=True) .values('id', 'name') .annotate( data=Func( Value('{"id": '), F('id'), Value(', "name": "'), F('name'), Value('"}'), function='concat', output_field=CharField(), ) ) .values('data') ), ), default=Value(list()), output_field=ArrayField(base_field=JSONField()), ) ) .order_by('id') ) return queryset This works (almost) flawlessly and gives me only 5 DB hits, perfect, or not... The problem is that I'm using Django HashID fields for the Program PK, and this query returns the pure integer value for each Program. I've tried a more "normal" approach, by getting the data using a SerializerMethodField: @staticmethod def get_programs(obj): role_attr = … -
Django: changing contents on a field on every save-like action
Before committing a record to the database, I want to do a sanity check on a certain field. More precisely, it is an ArrayField and I want to remove any NaN/None values and replace them by zero. However, there are many ways to create said record. A user might MyObject().save(), or MyObject.objects.create(), or MyObject.objects.bulk_create(), and even MyObject.objects.bulk_update(field=my_field). I believe there are also ways in that Django Rest Framework might use. How can I be sure that NaN/None is always replaced by zero before committing to the database? Should I overwrite all the above methods? Should I create a custom field that inherits from ArrayField but does all the data munging? What is the best practice? -

Best practice for tenant isolation with django-tenant-users in Django?
I'm building a multi-tenant application using Django with django-tenant and django-tenant-users for handling tenants and user authentication. However, I'm struggling to find the best approach to prevent users from one tenant accessing data or functionality of another tenant. I've explored custom middleware, Django's permission system, and user profile models, but haven't found clear guidance on enforcing tenant isolation within the Django framework. For those familiar with django-tenant and django-tenant-users, how do you ensure that users from one tenant cannot access data or features belonging to another tenant? Any insights, best practices, or references to relevant documentation would be greatly appreciated. Thank you! -

Convert Django-React dynamic website to static site
I want to convert my personal portfolio website here into a static site. Currently, I am deployed on AWS Elastic Beanstalk which has gotten expensive over the last year or so, due to me running out of AWS free tier. I'd like to convert the following routes: https://www.tomaspremoli.com/ https://www.tomaspremoli.com/#/tutoring https://www.tomaspremoli.com/#/portfolio https://www.tomaspremoli.com/#/resume into static html pages, save all images that are fetched in the code, and save all api call responses. Some api calls just run on page load, however, some api calls happen in js after buttons are clicked (such as when getting pictures for specific portfolio entries). I have access to the source code and all the root user permissions, and am not sure what the best course of action is here. I can't seem to find a tool that does this for me easily, and have been toying around with the Pupeteer js library, with some progress, but also out of my area of expertise and struggling to get much done. Is there any tools that could simplify this for me? So far i've tried various manual processes that don't seem to get me very far. -

Task Queue with cached libraries in Django
I am creating a WEB interface for various Python scripts through Django. Example in calculation.py I would have : import datetime def add_time(a, b): return = a + b + int(datetime.datetime.now()) Usages : A user could say "I want to run add from calculation.py with arguments [1, 3]" and that returns him the result when it's ready. A user could say "I want this to run add from calculation.py with arguments [1, 3] every 10 minutes and check if result is greater than X" and that would action something if it's true. Most of my script functions are quick but they need to import libraries that takes a lot of time to load. I am currently doing this directly with my Django service ; it's simple and load the libraries once which allows most of the next calls to be very fast but sometimes a heavy call is made and that is slowing down all my Django application and I seem limited if I want to have CRON scheduling for some scripts. Therefore I am looking at another solution. I started to look at : Celery (but it seems not supported anymore on Windows) Huey and Dramatiq Django-Q2 (easy to … -

The cascade should be structured like this Fach --> Reihe --> Ebene --> Behaelter My models.py from django.db import models from django.utils.text import slugify from wagtail.models import Page from wagtail.admin.panels import FieldPanel # InlinePanel # PageChooserPanel from django import forms from wagtail.admin.forms import WagtailAdminPageForm from django.utils.translation import gettext_lazy as _ # Create your models here. class NoTitleForm(WagtailAdminPageForm): title = forms.CharField(required=False, disabled=True, help_text=('Title is autogenerated')) slug = forms.CharField(required=False, disabled=True, help_text=('Slug is autogenerated')) def __init__(self, *args, **kwargs): super().__init__(*args, **kwargs) if not self.initial['title']: self.initial['title'] = _('auto-generated-title') if not self.initial['slug']: self.initial['slug'] = _('auto-generated-slug') class ReihePage(Page): base_form_class = NoTitleForm content_panels = [ MultiFieldPanel( [ InlinePanel("Fach", label="Fach", min_num=0, max_num=10), ] ), FieldPanel('title'), FieldPanel('slug'), ] def clean(self): super().clean() new_title = "anzahl from Fach" + "title from Fach" <--** How to get the values from the InlinePanel** self.title = new_title self.slug = slugify(new_title) class ReihePageOrderable(Orderable): page = ParentalKey(ReihePage, related_name="Fach", null=True) fach = models.ForeignKey("Fachpage", on_delete=models.SET_NULL, null=True) anzahl = models.IntegerField(default=1) class FachPage(Page): laenge = models.IntegerField(null=True, blank=True, verbose_name='Länge in mm') breite = models.IntegerField(null=True, blank=True, verbose_name='Breite in mm') content_panels = [ # FieldPanel('bezeichnung'), FieldPanel('laenge'), FieldPanel('breite'), FieldPanel('title'), … -
ModuleNotFoundError: No module named " CustomModule"
I've had a problem for a week now. I can't integrate unit tests into my Django project. I wanted to test one of my models. I did the necessary import to retrieve the class from models.py. But when I run the test, I get this error: ModuleNotFoundError: No module named "application name". Despite configuring the application in setting.py in INSTALLED_APPS. All the init files are present. And I have double-checked the names. I don't know why I have this problem. When I run the runserver, I get a 200 response. Everything works, but when I try to run a test... I see this error. Thank you for enlightening me. Best regards. Creating a simple test without importing the model works. So it's definitely linked to the module. It's not being found. -
