Collecting and Returning Error List in Django Rest Framework
I need to gather a list of errors in Django Rest Framework and return them to the frontend without performing any database or media operations. For example, errors during serialization, billing validation (if the user lacks permissions), or if a user tries to create something with a name that already exists. I want all validations to pass and then return this list to the user. I'm interested in potential approaches or if anyone has encountered a similar issue -

DEBUG=False is not showing static and media files in Django project on Cpanel
I've looked into many articles and videos on this topic, but either I didn't understand or the solutions were insufficient. I would be very happy if you could help. I developed a Django project and deployed it on cPanel. My static and media files don't work when DEBUG = False. What should I do to make it work properly on cPanel? I'm not sure if Whitenoise is being used during the deployment phase. How can I run my Django project on cPanel in a suitable and fully functional manner? Here are my current codes: Settings.py: DEBUG = True ALLOWED_HOSTS = ['*'] STATIC_URL = '/static/' STATIC_ROOT = '/home/ayvacioglu/ayvacioglu_v2/static/' # STATICFILES_DIRS = [os.path.join(BASE_DIR, 'static')] MEDIA_URL = '/media/' MEDIA_ROOT = '/home/ayvacioglu/ayvacioglu_v2/media/' Urls.py: from django.contrib import admin from django.urls import path, include from django.conf import settings from django.conf.urls.static import static urlpatterns = [ path('admin/', admin.site.urls), path('', include('pages.urls')), path('', include('portfolio.urls')), path('', include('services.urls')), path('', include('blog.urls')), ] + static(settings.MEDIA_URL, document_root= settings.MEDIA_ROOT) + static(settings.STATIC_URL, document_root=settings.STATIC_ROOT) If you need any other info i can provide it. Thank you so much -
Why is key name undefined when trying to display key value in html?
I'm trying to display database data in html using Javascript fetch api. I have looked at plenty of content for this problem but nothing seems to work right. However, I can display all the data in json format no problem. The problem occurs when I reference my model field names (key names) in javascript. sun_from_hour returns undefined. Is it a notation problem? I have tried several solutions. class SundayTime(models.Model): sun_teacher_id_time = models.ForeignKey(settings.AUTH_USER_MODEL, on_delete=models.CASCADE, null=True, blank=True, default='', related_name='sun_teacher_time_available_id') sun_from_hour = models.TimeField(null=True, blank=False) sun_to_hour = models.TimeField(null=True, blank=False) class SunJsonListView(View): def get(self, *args, **kwargs): times = list(SundayTime.objects.values('sun_from_hour', 'sun_to_hour')) return JsonResponse({'times': times}, safe=False) const sunButton = document.getElementById('sun_availability_show'); const sunContainer = document.getElementById('sun_availability_div'); const sunUrl = '/daily_appointment_availability-sun_json/' sunButton.addEventListener('click', reqSunData); function reqSunData() { fetch(sunUrl, { method: "GET", }) .then((response) => { return response.json(); }) .then(times => sunAdder(times)) .catch((error) => { console.error(error); }) } function sunAdder(times) { console.log(times); const ul = document.createElement('ul'); sunContainer.append(ul); Object.keys(times).forEach(timeData => { console.log(Object.values(times)); const li = document.createElement('li'); li.insertAdjacentHTML('beforeend', `<li>[${times.sun_from_hour}]</li>`); // here sun_from_hour is undefined li.textContent = JSON.stringify(times); ul.append(li); }) } // the json data that is displayed in html // {"times":[{"sun_from_hour":"00:00:00","sun_to_hour":"00:45:00"}, // {"sun_from_hour":"01:30:00","sun_to_hour":"01:45:00"}]} -
Problem loading wasm data for SciChart in Django - scichart2d.data = 404

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! -
