Can we avoid using django session to work with request body params data?
I have two django restframework classes(POST and GET)respectively, as seen below class demo(CreateAPIView): serializer_class = DummySerializer def post(self, request, *args, **kwargs): ID = request.data.get("ID") org = request.data.get("org") ent= request.data.get("ent") request.session['ID '] = ID request.session['org'] = org request.session['ent'] = ent request.session.save() class demo1(ListAPIView): serializer_class = MySerializer def get_queryset(self): ID = request.session.get("ID") org = request.session.get("org") ent= request.session.get("ent") I have two queries: My aim is to fetch those 3 params from request body in demo class and add it to a session and then use the values in demo1 class for further data manipulation. So, I migrated the default django in-built apps in the development sqlite DB and I could see the flow of the data from demo class to demo1 class. But in my actual working environment, I am trying to avoid the session migrations until I don't have any further options. In a new django app which I have created in my working environment, in the models.py I have define the structure of an existing table from my MySQL db. Hence, if I do a migrations and then mnigrate, will the migrations going to make any further changes in the MYSQL tables, or it will only compare the existing schema and … -
Document repository and search using Generative AI and Django
I am not sure, this is right forum to get help here. But, need some expert help on this. I have created a chatbox using Javascript, Django framework and AI. If user asks any question from chatbox, then model will help to answer with defined responses.

If yes, Any reference link/ which API's which help for my requirement ? -
Desktop App with Django, DRF, Vue 3 JS, Electron JS and Forge Electron - links out of the package error on make
What I am trying to do: Build and package a very simple desktop app using: Python Django as a backend (with Django Rest Framework for a rest api) Vue 3 js for the frontend (using Axios to consume the API) Electron JS to make it a desktop app and Forge Electron to package it. I am using a virtual env for the Django app (pyenv). The build and run works perfectly: the app just fetch a list of posts from Django using DRF endpoints and a GET request from the Vue App. The issue is when I want to make a package and deploy it. Forge Electron comes with an error: An unhandled rejection has occurred inside Forge:links out of the package. And more specifically: An unhandled rejection has occurred inside Forge: Error: /var/folders/3v/kk4yh47x7hlgs8rv94dxnx700000gn/T/electron-packager/tmp-2YhdSt/Electron.app/Contents/Resources/app/python/.venv/bin/python: file "../../../../../../../../../../../../Users/macbookpro/.pyenv/versions/3.10.4/bin/python3.10" links out of the package I have tried multiple things I have found browsing: set asar:false --> it complains that it needs to be true or an object see if the issue was linked to node.js libs --> I found something about node-gyp bit it seems not relating to the issue. The issue seems to be linked to where Python is located... If that … -

How to Use React to Authenticate to Django REST Framework
I am trying to figure out how to authenticate to the Django REST Framework with React. I am using AXIOS. But no matter what I try, I seem to get a 403 - CSRF verification failed. Request aborted. In Chrome, I go to DRF's default login point. I enter the username and password and click submit. It works in Chrome. In DevTools, I can see the POST. Now if I try that same POST in React, I get a 403 with the CSRF error. How is that even possible? In React I am doing the same thing that Chrome is doing. How can it produce a different result? Here's me logging in from Chrome... enter image description here What am I missing? What am I missing? I keep reading about doing a GET request, looking at the set-cookie csrf token and value, and putting that in a header on my POST request. I've tried that and every variation I can think of to no avail. -
What are the best practices or recommendations that will make it easier to access related models in django?
class Customer(models.Model): user = ForeignKey(User, on_delete=models.CASCADE) ... class Organization(models.Model): usercustomer = models.ForeignKey(Customer, on_delete=models.CASCADE) ... In the template, to get the user name, I write {{ organization.customer.user.first_name }} how can I shorten it? class Organization(models.Model): usercustomer = models.ForeignKey(Customer, on_delete=models.CASCADE) ... def get_user_first_name(self): return self.usercustomer ].user.first_name I wanted to solve this by writing methods in the model, but it's not so convenient, I want to find a more flexible solution -
Displaying Data from Database (Django) [closed]
I'm a beginner. Using Django for the first time. I'm building a website for pet adoption. Currently working on the database UI. I want the database to be displayed somewhat like this... example UI or something like petfinder -> example UI Basically, when someone comes to look for all the available pets for adoption, I want them to be displayed as single objects...would django_tables2 be the right fit for this? It's not exactly a table so I don't know if I should be using django_tables2 for this. Are there other ways to achieve this kind of UI for displaying data? Haven't really tried anything except django_tables2 and it's displaying everything in a table format as expected but that's not really what I want. -

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.

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"}]} -

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

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.

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! -
