Allauth SocialConnectView django rest framework
can someone help please, the access token retrieved from Facebook is not being stored in the socialaccount_token table after a successful social login. This prevents my application from using the token later for data retrieval. this is my code from dj_rest_auth.registration.views import SocialConnectView from allauth.socialaccount.providers.facebook.views import FacebookOAuth2Adapter import facebook from allauth.socialaccount.providers.oauth2.client import OAuth2Client class FacebookConnect(SocialConnectView): adapter_class = FacebookOAuth2Adapter client_class = OAuth2Client the data is stored in socialaccount_socialaccount table by default , but nothing stored in socialaccount_socialtoken -
Handle multiple clients in a browser terminal that is created by xtermjs
My browser terminal application runs without problem while it is used by a single client but when another client connects to it and tries to use the same terminal is shown to the new client. Also when i open it in another tab it shows the same terminal too. Defining seperate terminals in xtermjs like termA and termB is not viable since number of clients is not certain. The application runs with django in backend. Xtermjs is only used for visualization and getting user input. A pseudo terminal and bash process handles terminal logic in the django. My first approach was to implement multiprocessing in the django but i failed to achieve it. I am open to different approaches to solve this issue. views.py: import os from django.shortcuts import render import socketio import pty import select import subprocess import struct import fcntl import termios import signal import eventlet async_mode = "eventlet" sio = socketio.Server(async_mode=async_mode) fd = None child_pid = None def index(request): return render(request, "index.html") def set_winsize(fd, row, col, xpix=0, ypix=0): winsize = struct.pack("HHHH", row, col, xpix, ypix) fcntl.ioctl(fd, termios.TIOCSWINSZ, winsize) def read_and_forward_pty_output(): global fd max_read_bytes = 1024 * 20 while True: sio.sleep(0.01) if fd: timeout_sec = 0 (data_ready, _, … -
Rounding off decimals in Django not working as expected?
I am using Django version 3.2.16. In Django I am using below code. Here for example income__ownership is 2500 and the value of amount_field is 14826.So when multiplying 14826 by.25 it gives value as 37.715 and I want the rounded result as 35.72 but Django Round gives result as 36. How to achieve desired result? amount_annotation = ExpressionWrapper( # Use Django's Round function to round the base value to 2 decimal places Round( F(amount_field) * (Cast(F('income__ownership'), FloatField()) / 10000), precision=2, # Round to 2 decimal places output_field=FloatField() ) * 100, # Multiply the rounded value by 100 output_field=IntegerField() ) -

TinyMCE renders an extra widget
I use django-tinymce to render TinyMCE widgets in my forms. If updated to the latest version 6.8.3 (2024-02-08), I have two widgets on the same form field instead of one. This is the Django template: {% extends "layout.html" %} {% load i18n %}{% load static %} {% block title %} ... {% endblock %} {% block head %}{{ form.media }}{% endblock %} {% block content %} {% if user.is_authenticated %} <div id="create"> <form id="cascade" class="mt-3" method="post" action="." enctype="multipart/form-data"> {% csrf_token %} {{ form.non_field_errors }} {% for field in form %} {% if field.is_hidden %}{{ field }}{% else %} <div class="mb-3"> <label for="{{ field.id_for_label }}" class="form-label">{{ field.label }}:</label> {{ field }} {% if field.help_text %} <div class="form-text">{{ field.help_text|safe }}</div> {% endif %} <div id="{{ field.auto_id }}" class="invalid-feedback">{{ field.errors }}</div> </div> {% endif %}{% endfor %} <button class="btn btn-primary" type="submit" name="action">{% translate "Submit" %}</button> </form> </div> {% endif %} {% endblock %} This is how the form field content using TinyMCE is actually rendered: <div class="mb-3"> <label for="id_content" class="form-label">Содержимое:</label> <textarea class="form-control tinymce" cols="40" data-mce-conf="{&quot;theme&quot;: &quot;silver&quot;, &quot;height&quot;: 500, &quot;menubar&quot;: false, &quot;plugins&quot;: &quot;autolink,lists,link,image,charmap,preview,hr,searchreplace,code,media,table,paste,help,wordcount&quot;, &quot;contextmenu&quot;: &quot;paste | link image table&quot;, &quot;toolbar&quot;: &quot;bold italic underline strikethrough | bullist numlist | blockquote hr charmap | table | … -
Is there a hook to modify field value in Django?
On any type of Django Field, validators is available where I can hook my own custom validator. I understand I cannot change the value in the validator, it must either return None or django.core.exceptions.ValidationError. What I want to do is I want to change the value of the field itself, before it gets saved. For example, I want to store ISO 3166 Numeric Code as a column: def digit_only(value): if not value.isdigit(): raise ValidationError( _("%(value)s contains a non-digit"), params={"value": value}, ) class Country(models.Model): # ... iso3166_numeric = models.CharField(max_length=3, validators=[digit_only]) # ... So far, so good. Now, if the value input is '1', I want to convert it to '001' before the value is stored on the table. Without creating a new Field type and then writing custom Field.to_python(), can I achieve the same, as simply as using validators? I am still learning, and I have not reached as far as Forms yet, but I am trying to achieve the above when seeding from a CSV through Djano command. Yes, I could modify the value immediately on reading from CSV, but I am trying to find out if there is one single place where I can do this so that I … -
Authentication and Security in Django/QT Application
I'm currently working on an application that utilizes Django for the backend and QT/C++/QML for the frontend. One of the key aspects I'm focusing on is authentication and ensuring the security of the application. Here's a brief overview of how it works: When a user logs in, the frontend sends a request to the API, and if the credentials are valid, the user receives a TOKEN, which is then stored in a class variable. Subsequently, this token is sent with each subsequent request to the API. Now, my question is: Is this approach secure? Where should such a token be stored? Is using a class variable acceptable in this scenario? It's worth mentioning that this application doesn't handle sensitive data, but I still want to ensure proper security measures are in place. I'd appreciate any insights or recommendations on best practices for authentication and security in this context. Thank you! I was tried to store the data in variable inside the CPP class. -

Make Python async queue based on two dynamic Django ORM requests
I need to make chat offers to the agents. Both are taken from Django ORM dynamically, agents have limits of maximum active chats. One agent must have one offer at a time. Chat should be offered to different agents sequentially. Here is example of try showing the expected logic but it offers only one chat at time. async def offerer(): while True: await asyncio.sleep(0.1) async for chat in Chat.objects.filter(Q(status = 'initiated') | Q(status = 'queued')).order_by('last_init')[:5]: chatid = chat.chatid dobreak = False account = chat.chatacc_id async for agent in Agent.objects.filter(status = 'ready', accounts = account, number_active__lt = maxchats).order_by('number_active'): data = {"type": "chat_initiated", "chatid": chat.chatid} await channel_layer.group_send(f'agent_{agent.agentid}', data) await asyncio.sleep(5) # check if chat was accepted chat_updated = await Chat.objects.aget(chatid = chatid) if 'active' in chat_updated.status: dobreak = True break else: await channel_layer.group_send(f'agent_{agent.agentid}', {"type": "cancel", "value": chat.chatid}) if dobreak: break async def main(): asyncio.create_task(offerer()) loop = asyncio.new_event_loop() loop.create_task(main()) loop.run_forever() What is the correct way to do that? -

How do I create a hidden field in Django 4/5?
I am using this simple example just for discussion: class User(models.Model): first_name = models.CharField(...) last_name = models.CharField(...) full_name = first_name + ' ' + last_name I want only full_name to be accessible to be created, saved, retrieved. It is a combination of first_name and last_name. When the full_name needs to be saved, it will be split by spaces, and first split goes to first_name and rest goes to last_name. I don't want first_name and last_name to be directly accessible from forms or even Django commands that may directly use User instantantiation, ModelModel manager create or User save methods. Do I have to hack into the Metaclass (like here: https://github.com/vitaly-efremov/django-private-field/blob/master/private_field_meta.py, 7 years old code), or is there something simpler in Django 4/5? -

Desperate for help: Django sessions failing intermittently
I’m in desperate need of some Django help. I wrote an app last year for a community event I run, called Nashville Tabletop Day. The app allows people to scan QR codes to interact with games they can play during the day. Locally it runs great. However when I push it to Fly.io it runs, but reliably drops sessions. By that I mean I can log in, browse to a page or two, and then the session just vanishes. It even happens if I stay on the same page and just reload a few times. It doesn’t happen immediately, or I’d think perhaps the database was the issue. But after 15-30 seconds, or a few page loads—poof. The event is this coming Saturday and this app has to be ready go. I’m tempted to think it could be a config issue, but this app ran last year, almost flawlessly and I’ve only made a few small updates this year.

How do I override the delete() method in Django's DeleteView to send a success message?
I'm using Django 5.0.3. I have a job listings app, with a DeleteListingView. I want to override the delete() method, so that I can use messages.success() to send a message to the success url's template once a listing is deleted. However, the delete() method isn't being overridden. A listing gets deleted, and I'm redirected to the correct url, but the message isn't sent. I've even tried to add a print() statement inside delete() to see if it appears in cmd, but it doesn't. from django.contrib.auth.mixins import LoginRequiredMixin from django.contrib import messages from django.urls import reverse_lazy from django.views.generic import ListView, DetailView from django.views.generic.edit import UpdateView, DeleteView, CreateView from .models import Listings class ListingsListView(ListView): model = Listings template_name = 'listings/listings_list.html' context_object_name = 'listings' class DeleteListingView(LoginRequiredMixin, DeleteView): model = Listings template_name = 'listings/listing_delete.html' context_object_name = 'listing' success_url = reverse_lazy('listings') def delete(self, request, *args, **kwargs): listing = self.get_object() listing_title = listing.job_title messages.success(self.request, f"Listing titled '{listing_title}' was deleted successfully.") print(f"delete() has been overridden successfully.") # To appear in cmd return super().delete(request, *args, **kwargs) and in listings_list.html template: {% for message in messages %} <p> {{ message }}</p> {% endfor %} Nothing I've tried is working, and I can't seem to find a solution anywhere.
