Problem loading wasm data for SciChart in Django - scichart2d.data = 404
I can only load a blank SciChart surface with a "loading... spinner". Firefox console says: Uncaught Error: Internal Server Error : http://127.0.0.1:8000/charts/scichart/scichart2d.data Django is serving scichart2d.wasm correctly, but not scichart2d.data (which is in the same static dir) My HTML and javascript seem to be working, the Webpack bundle loads and logs to console. I followed the SciChart tutorial here. I don't know where this problem is coming from. Is it Webpack, Django, or SciChart?

Django: Migrating from multiple databases to a single database?
I'm relatively new to Django (and web systems architecture more broadly) and mistakenly thought that building my project with separate databases for user data and core application data was a good idea. I originally created two applications, core and users, with separate router classes: settings.py DATABASES = { "default": { }, USERS_DATABASE: { "ENGINE": "django.db.backends.postgresql", "NAME": "postgres", "USER": ..., "PASSWORD": ..., "HOST": "127.0.0.1", "PORT": "5000", }, CORE_DATABASE: { "ENGINE": "django.db.backends.postgresql", "NAME": "postgres", "USER": ..., "PASSWORD": ..., "HOST": "127.0.0.1", "PORT": "5000", }, } routers.py class AuthRouter: route_app_labels = { "auth", "contenttypes", "sessions", "admin", } ... class CoreRouter: route_app_labels = { "core", } ... Knowing now that it's not necessary for our project to use separate core and users databases (and that doing so will give us more problems in the future), I'd like to migrate the users database into the core database and assign the core database to be the default. There are only two users at the moment, so I'm fine with losing the users data and recreating the superuser if need be. However, migrating the users database doesn't seem as straightforward as editing settings.py and creating migrations. Editing the databases settings.py to both point to the core database and … -
how to collect information of this json file through django?
so, I'm creating a django weather app project. My idea is: The user input the name of a city The city need to be in my database If it is, so the weather api will receive the city coordinates and output data I would like to know how do I get parameters of a json file through django. Do I need to do it with the views? create a model? some request? I did this in views: from django.http import HttpResponse import requests from datetime import datetime from zoneinfo import ZoneInfo def weatherdata(request): response = requests.get('api is here').json() context = {'response':response} return render(request,'home.html',context) def citynamesinfo(request): response = request.FILES() #I don't what to do here # input localization # recognize specific coordenates and in models: from django.db import models # Create your models here. class Weather(models.Model): city = models.CharField(max_length=100) temperature = models.DecimalField(max_digits=5,decimal_places=2) condition = models.CharField(max_length=100) precipitation = models.CharField(max_length=100, null=True) humidity = models.DecimalField(max_digits=5,decimal_places=2) considering the json file is like this: [{"geoname_id": "3112344", "name": "R\u00e1fales", "ascii_name": "Rafales", "alternate_names": ["Rafales", "Rafels", "R\u00e1fales", "R\u00e1fels"], "feature_class": "P", "feature_code": "PPLA3", "country_code": "ES", "cou_name_en": "Spain", "country_code_2": null, "admin1_code": "52", "admin2_code": "TE", "admin3_code": "44194", "admin4_code": null, "population": 175, "elevation": null, "dem": 634, "timezone": "Europe/Madrid", "modification_date": "2012-03-04", "label_en": "Spain", "coordinates": … -
Django-Crispy-Forms, different layout for forms of a formset
I have a formset, this formset consists of 12 forms, each form has a different initial, and the forms have crispy helper layouts. However, since each form has its own distinct initials, we can't have a general layout for all of the forms, which mean we can't set the layout for the formset. Is there anyway we can set a different layout for each form in the formset? i've already tried overriding _construct_form of the formset but it appears that it doesn't work. -
Django static files Dokku
I am encountering an issue with Django and Whitenoise where my static files are not being served correctly, resulting in 404 errors and MIME checking errors. I have configured my config/settings.py file with the necessary settings for static files and Whitenoise middleware: INSTALLED_APPS = [ # some apps 'django.contrib.staticfiles', # my apps ] MIDDLEWARE = [ # some middleware 'django.middleware.security.SecurityMiddleware', 'whitenoise.middleware.WhiteNoiseMiddleware', ] STATIC_URL = '/static/' BASE_DIR = os.path.dirname(os.path.abspath(__file__)) STORAGES = { "staticfiles": { "BACKEND": "whitenoise.storage.CompressedManifestStaticFilesStorage", }, } STATIC_ROOT = os.path.join(BASE_DIR, 'staticfiles') However, when I try to access static files such as http://example.com/static/css/style.css and http://example.com/static/js/script.js, I get 404 errors, and the browser console shows MIME type errors: Refused to apply style from 'http://example.com/static/css/style.css' because its MIME type ('text/html') is not a supported stylesheet MIME type, and strict MIME checking is enabled. Refused to execute script from 'http://example.com/static/js/script.js' because its MIME type ('text/html') is not executable, and strict MIME type checking is enabled.

Abstract model in Django with ForeignKey doesn't inherit as expected
When attempting to execute makemigrations in my Django application, I encounter errors related to circular references. I have defined an abstract class A that inherits from models.Model, and two child classes B and C. However, it seems I am making mistakes with the relationships between these classes. Here is the relevant code: class A(models.Model): class Meta: abstract = True id = models.AutoField(primary_key=True) z = models.ForeignKey(Z, on_delete=models.CASCADE, related_name="relateds") class B(A): algo = models.CharField(max_length=32, default="") class C(A): foo = IntegerField() I am facing the following error: z.B.z: (fields.E305) Reverse query name for 'z.B.z' clashes with reverse query name for 'z.C.z'. Any help or suggestions on resolving this issue would be greatly appreciated! -
Create an app: input data from user and export to csv. Python?
I'm a beginner in development and I'm looking to create a lightweight Python application. The idea is to have a user interface that allows users to input data through some mandatory steps and later export them to a CSV file. For this purpose, I'm considering whether to go for a desktop application using Tkinter or a local web app with Flask or Django. I would appreciate advice on the best choice between these two options, considering simplicity, lightweight nature, and portability. P.S. I've already tried with django, but after a while I started to doubt that it was too "heavy". Thanks! -

How to run Celery and Django web app simultaneously on Railway?
I'm trying to deploy a Django web application along with Celery for background task processing on Railway. I've configured my railway.json deployment file as follows: { "$schema": "https://railway.app/railway.schema.json", "build": { "builder": "NIXPACKS" }, "deploy": { "startCommand": "celery -A core worker --loglevel=INFO && python manage.py migrate && python manage.py collectstatic --noinput && gunicorn core.wsgi --timeout 60", "numReplicas": null, "healthcheckPath": null, "healthcheckTimeout": null, "restartPolicyType": "ON_FAILURE", "restartPolicyMaxRetries": 10, "cronSchedule": null } } However, with this configuration, only Celery starts, and the Django web server (gunicorn) doesn't seem to run. How can I adjust my deployment configuration to ensure that both Celery and the Django web app start and run simultaneously? I've tried rearranging the startCommand, placing celery at the end, but it doesn't seem to work. Any guidance or best practices for configuring Celery and Django web app deployments on Railway would be greatly appreciated. Thank you! -

Dynamically add/remove DateFields in Django formset
I have a very specific problem which is related to the package django-bootstrap-datepicker-plus. In my Todo list application I want to have the possibility to have tasks pop up on a number of specific dates. I got my model set up, I got my form including a formset set up, and I even have a JavaScript that handles the dynamic add/remove procedure.

Challenge with Ordering Django Signals and Celery Tasks for Group Operations
I'm facing an issue in my Django project where the execution order of Django signals and Celery tasks is causing complications, particularly in managing group operations asynchronously. Specifically, when there's a change in group administrators triggering the update_group_admins signal, the create request task (create_group_async) should ideally be executed before the tasks for adding or removing group members (add_group_admins_async and remove_group_admins_async). However, despite my meticulous planning, the sequence of execution remains incorrect, leading to errors and inconsistencies in the system. To address this issue, I've attempted various approaches to reorder the tasks and signals within my codebase. My expectation was that by ensuring the correct sequence of execution, the create request task (create_group_async) would be processed before the tasks for adding or removing group members (add_group_admins_async and remove_group_admins_async). However, despite my efforts, the execution sequence remains erroneous, and I haven't been able to achieve the desired outcome. -
How to solve logout error when using Django-Jazzmin?
I hope you are doing fine! I have built a django project recently, and while searching for methods to customize the admin panel, I found Django-Jazzmin. It is working and cool and all that, but I have one single problem with it, whenever I try to logout from the admin page, it returns the error 405, a.k.a "method not allowed". I am working with the Django 5.0.2 framework. Did someone find the solution for this problem? I tried to go to "my-virtual_env\Lib\site-packages\jazzmin\templates\admin\base.html" and modify the logout block to : <form method="post" action="{% url 'admin:logout' %}"> {% csrf_token %} <button type="submit" class="dropdown-item"> <i class="fas fa-users mr-2"></i> {% trans 'Log out' %} </button> </form> but it didn't help! -
Django - How to use AJAX within a form
I'm trying to use AJAX for the first time as we have a Django project but a required feature is for one form to behave more like a react app or SPA so I'm trying to use AJAX to add that functionality. I have the following template for the page. It has a form to let the user select from a dropdown what their highest education is and should have a modal appear to let the user input a qualification at a time to be added to the database and displayed on the table. The issue is when the user fills out the modal and clicks submit it seem's to perform just a normal GET request as can be seen below rather than the API request to create qualifications from the modal. AJAX seemingly isn't intercepting the request.
