How to paginate ckeditor content in django?
I have ckeditor content as book content. I want to show the content in a fixed width and height container. Instead of scroll. there will be option to navigate pages. Next button and previous button for navigate pages. from django.db import models from django_ckeditor_5.fields import CKEditor5Field class Book(models.Model): title = models.CharField(max_length=255) slug = AutoSlugField(populate_from='title') description = models.TextField() content = CKEditor5Field(config_name="extends") At first I have tried this feature with the default models.TextField(). By counting the words I have splited as pages in javaScript. It was ok but for more text formatting I have to use ckeditor and the ckeditor saves content as html so I can't figure out how I will split the page. Because If I want to split with the previous approch it's possible to miss starting or ending tag in a page. I am using django-ckeditor-5 -

The code works on my network, but not on the university's network
I have a Django server with DRF and custom JWT cookies through middleware. The frontend is built in Next.js and consumes the server routes as an API. Everything works on my machine and network, as well as on some friends' machines who are involved in the project, with the cookies being created and saved correctly. The problem is that this doesn't happen on the university's network, even though it's the same machine (my laptop) and the same browser. At the university, the cookies are not saved, and the error "Cookie 'access_token' has been rejected because it is foreign and does not have the 'Partitioned' attribute" appears. Both codes are on GitHub, and the only thing hosted in the cloud is the database. I am aware of the cookie creation and saving configurations, as well as the CORS policies. I can't figure out where I'm going wrong... Can anyone help me? I can provide the links if possible! Thanks in advance! -

Sending data to a form using data from previous GET request
I have a dictionary app where users can view the words (Lemma) filtered by their first letter. I would like for users to be able to then filter those results according to combinations of part of speech (each Lemma has exactly one part of speech) or tags (each Lemma can have 0 to many tags); e.g., select only Lemma that are nouns or verbs or are tagged as agricultural vocabulary. I currently have two forms, one for selecting the first letter and one for selecting the part of speech/tag (the facets). class LemmaInitialLetterForm(forms.Form): LETTERS = [ ... ] initial = forms.ChoiceField( widget=forms.RadioSelect( attrs={"class": "lem_init"} ), choices=LETTERS ) class FacetSideBarForm(forms.Form): poss = forms.MultipleChoiceField( required=False, widget=forms.CheckboxSelectMultiple, label='Parts of speech', choices=list() ) tags = forms.MultipleChoiceField( required=False, widget=forms.CheckboxSelectMultiple, label='Tags', choices=list() ) def __init__(self, poss=None, tag_list=None, *args, **kwargs): super(FacetSideBarForm, self).__init__(*args, **kwargs) if poss: self.fields['poss'].choices = [ (pos, pos) for pos in poss ] if tag_list: self.fields['tags'].choices = [ (tag, tag) for tag in tag_list ] I've been able to display a list of Lemma filtered by first letter with the following view: class LemmaListView(generic.FormView): template_name = "emedict/lemma_home.html" lemmalist = None def get(self, request, *args, **kwargs): form = LemmaInitialLetterForm(self.request.GET or None) if form.is_valid(): initial = request.GET["initial"] … -
Django Simple JWT + Axios, always getting 401. How can I fix this?
I’m using Nuxt and a pinia store to store the token (the token is present in the store). I've created a plugin for Axios as follows: import axios from "axios"; export default defineNuxtPlugin((NuxtApp) => { axios.defaults.baseURL = "http://127.0.0.1:8000/api/"; axios.defaults.withCredentials = false; axios.defaults.proxyHeaders = false; if (process.client) { let token = window.localStorage.getItem("authTokens"); if (token) { token = JSON.parse(token); console.log(token.access); axios.defaults.headers.common["Authorization"] = `Bearer ${token.access}`; } } return { provide: { axios: axios, }, }; }); The endpoint in Django REST Framework is defined like this: class CreateEvent(CreateAPIView): permission_classes = [IsAuthenticated] serializer_class = CreateEventSerializer def post(self, request, *args, **kwargs): data = request.data.copy() z = request.META.get('HTTP_AUTHORIZATION') data['creator'] = request.user print(request.user, '--------------------') data['types'] = get_type_by_int(request.data.get('type', None)) serializer = self.get_serializer(data=data) if serializer.is_valid(): serializer.save() return Response(serializer.data, status=status.HTTP_201_CREATED) return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST) The method I use to call this endpoint is as follows: async sendEvent(): Promise<void> { try { const { $axios } = useNuxtApp(); const response = await $axios.post("event/create/", { latitiude: this.latitiude, longitude: this.longitude, description: this.description, type: this.type, }); console.log("Event sent:", response.data); } catch (error) { console.error("Error while sending event"); } } No matter what I do, I keep receiving a 401 error with the message: Authentication credentials were not provided.

Django: No tables found in the database after running migrations
I'm working on a Django project, but I'm facing an issue where no tables are being created in my database even after running migrations. Django version:5.1.3 Database:MySQL OS:ubuntu 24.04.1 LTS 1 I ran python manage.py makemigrations, and it successfully generated migration files 2 I ran python manage.py migrate, and it executed without any errors. 3 However, when I check the database in phpmyadmin, No tables found in database. I also tried these troubleshooting steps: 1 Verified that the database file exists. 2 Ensured that the INSTALLED_APPS list includes my app. 3 Checked that the models are defined properly in the models.py file. 4 Looked for migration history with python manage.py showmigrations, and all migrations are marked as applied. What could be causing this issue? Are there any additional steps I can take to debug or resolve this problem? I’d appreciate any guidance or suggestions. Let me know if more information is needed. -

Django 5.1 UserCreationForm won't allow empty passwords
I am upgrading a Django 3.0 app to 5.1 and have been moving slowly through each minor release. So far so good. However, once I upgraded from Django 5.0 to 5.1, I saw changed behavior on my "Create New User" page, which used to allow empty passwords, with a random password being generated if none is supplied. Now, I can no longer submit an empty password. I get a "required field" error on both the password fields, even though the fields are both explicitly set as required=False. I know there were some changes (5.1.0, 5.1.1) to the UserCreationForm class in Django 5.1. I tried using AdminUserCreationForm instead of UserCreationForm and setting the usable_password field to None, but it still won't allow empty passwords like before. Any ideas?

How can I configure a Django Unfold "custom site" with a required URL parameter?
I'm attempting to create a "custom site" using Django Unfold. I have an existing admin panel configured using the more basic ModelAdmin approach which works nicely. However, I need to create a separate admin panel using the "custom site" feature for use with django-tenants. I want the URL structure to look like: http://localhost:8000/tenant-admin/$tenant-id/. Within the "custom site", Django Tenants will scope the Postgres search path to the correct Postgres schema and the admin will be able to manage all of the models for a given tenant. I have defined my custom site as follows: from django.contrib import admin from django.urls import path from unfold.sites import UnfoldAdminSite from unfold.admin import ModelAdmin from tenant_app.models import Foo class TenantAdminSite(UnfoldAdminSite): # hopefully not needed -- but this is the first instance of admin:index causing problems # index_template = "admin/dashboard.html" def get_app_list(self, *args, **kwargs): # this lives at apps/tenant_app and is the only app that this TenantAdminSite # will use. Not sure if strings are valid here? return ["tenant_app"] def get_urls(self): """ Add custom URLs to the default admin site, capturing the tenant name. """ from django.urls import reverse # Capture the tenant name as part of the URL urls = super().get_urls() # Add custom … -
How to find user_id in Django endpoint
I have this Django endpoint: def get(http_request: HttpRequest, id: str): book_account_id = UUID(id) user_id: UUID = http_request.user.id affiliated_price_subscriptions = None response = BookAccountService.filter( id=book_account_id ).prefetch_related( Prefetch( 'subscription_set', queryset=SubscriptionRepository.filter( active=True ).prefetch_related( Prefetch( 'pricesubscription_set', queryset=PriceSubscriptionRepository.filter( Q(status=PriceSubscription.PriceSubscriptionStatus.PENDING) | Q(status=PriceSubscription.PriceSubscriptionStatus.REQUIRES_PAYMENT) ), to_attr='price_subscriptions' ) ), to_attr='subscriptions' ) ).first() affiliated_price_subscriptions = list(chain.from_iterable( subscription.price_subscriptions for subscription in response.subscriptions )) # The user must be part of the group that owns the book account # or the book acc must have at least one pending subscription if not PersonGroupService.exists( person__user_id=user_id, group__bookaccount__id=book_account_id ) and affiliated_price_subscriptions is None: return RestResponse( status=status.HTTP_200_OK, data=Response( code=24, error=True, messages=[ f"User with ID {user_id} does not have access to book account with ID {book_account_id}." ], data=None, ).to_dict(), ) return (...) Basically what it does is to get the book_account either if: the user.id belongs to a person that belongs to the group of that book_account. The book account has a related a related price-subscription with a PENDING or PENDING_PAYMENT status. I erased the is_authenticated: True since for 2) you do not need to be logged in to obtain the book_account data. However, when I call the endpoint while authenticated I get an error since user_id is null. I realized the only way to not have … -
Django Daphne not working with WSS, Ngnix and Docker
I'm trying to deploy an application built with Django and Daphne to open a WebSocket connection. Everything works perfectly on localhost, as I'm not using Nginx. However, in production, I need to use Nginx to serve SSL/HTTPS connections, including WSS. Unfortunately, it no longer works. When I try to use HTTPS on port 443, the WebSocket connection remains pending indefinitely until it eventually fails. I really considered removing Nginx because I found a Daphne configuration that runs on port 443 with an SSL certificate. daphne -b 0.0.0.0 -e ssl:443:privateKey=/privkey.pem:certKey=/fullchain.pem core.asgi:application However, I would still need Nginx to serve static files. I feel like I've tried everything so far.

500 server error with Django Rest Framework
I am using Django/DRF with Djoser and djangorestframework-simplejwt to create an API for full authentication including signup, login, activation, forgot password and reset password. I followed along with this YT tutorial For some reason, when I send a POST request in Postman to localhost:8000/api/users/ I am getting this error and I have no idea why at this point, django.db.utils.DatabaseError: Save with update_fields did not affect any rows. I'm not using SQLite but an actual Postgres db on localhost. I've tried changing user.save(self._db) to just user.save(), same error. I've updated Django to 5x. Django is the only one with a significant update compared to the tutorial, he uses Django 4x. I did move some of the original model code to a managers.py file based on this testdriven.io tutorial I've been able to run python manage.py runserver with no errors after doing so. It doesn't seem to be any code related to the tutorial but something with the python packages... Here is the error from the cli: [24/Jan/2025 16:40:07] "POST /api/users/ HTTP/1.1" 500 138392 Bad Request: /api/users/ [24/Jan/2025 17:05:47] "POST /api/users/ HTTP/1.1" 400 62 Internal Server Error: /api/users/ Traceback (most recent call last): File "/home/da/projects/full_auth_api/full_auth/backend/venv/lib/python3.12/site-packages/django/core/handlers/exception.py", line 55, in inner response = get_response(request) … -
Puppeteer not working with Django Viewset
