Django socketio process
I'm dealing with a little problem that I need to solve. I have an application in Django and I need a websocket, but I don't like Django channels, so I created a socket server in Flask and I'm trying to connect Django to it, by creating middleware that when called starts a process that sends messages through the process what it has in the queue But either the shared variable doesn't work or the process itself doesn't work properly. Please if you have any advice or solution write also how to terminate the process with socket when django terminates This is my code: socket.py --- import socketio import json from project.settings import SOCKET_CONFIG, MANAGER from multiprocessing import Process sio = socketio.Client() class Socket: queue = MANAGER.list() def __init__(self, get_response): self.get_response = get_response thread = Process(target=Socket.process_loop, args=()) thread.start() def __call__(self, request): return self.get_response(request) @staticmethod def process_loop(): sio.connect('http://{}:{}'.format(SOCKET_CONFIG["host"],SOCKET_CONFIG["port"])) while True: try: import time time.sleep(1) data = Socket.queue.pop(0) sio.emit('message', data) except BaseException as e: print(e) settings.py --- import os, subprocess from multiprocessing import Process, Manager MANAGER = Manager() SOCKET_CONFIG={ "host":"localhost", "port":8001 } ... -

Root path analogue in uWSGI as in Uvicorn
Uvicorn has the option --root-path (https://www.uvicorn.org/settings/#http) that helps a lot if the application is mounted to a specific path, distinct to /. For example, in case of a Django application I can run it with: uvicorn myproj.asgi:application --host=localhost --port=8001 --root-path="/myproj-custom-path" So if I configure the Nginx location /myproj-custom-path/ as proxy_pass http://localhost:8001/, I can access the application by http://localhost:80/myproj-custom-path with all the functionality, including the Admin panel, without the need to specify the root path anywhere else in the project. Is there a similar option or a way to do the same with uWSGI? -
Django register function accepting a new user while the login function can't find it
I'm creating a site using django, python and html. I have an app called account which I have currently written two functions for: register and login_view. My register function works properly, accepting a user unless their username is already taken or their two passwords are not a match. However, my login_view function doesn't seem to recognize the same user that has just been created in the register page, giving me this error: return render(request, 'account/login.html', {'error': 'Wrong username or password.'}) Here are the files inside my account folder I've worked on so far: views.py: from django.shortcuts import render from django.contrib.auth.models import User from django.contrib.auth import authenticate, login, logout def register(request): if request.method == 'POST': if request.POST['password1'] == request.POST['password2']: the_username = request.POST['username'] try: the_user = User.objects.get(username = the_username) return render(request, 'account/register.html', {'error': 'Username already taken.

Does Python being a loosely typed programming language make it less secure?
We have this huge issue as a team in choosing a programming stack to develop a web application for a client, one group prefers Django, while the other prefer Springboot claiming that python is a loosely typed programming language, and that makes it less secure unlike Java. In terms of security is Java better than Python? -
sorl-thumbnail adds a background color when padding is used

How do I connect a website to the postgres database?
I am developing a website using django rest framework and react. And I transferred from the test VM to the timeweb cloud virtual cloud and ran into the problem that when connecting to the site, the site starts without information from the postgres database. And also when starting the react web server.the js command "npm run start" outputs an error in browsers on remote client computers: JSON.parse: unexpected character at line 1 column 1 of the JSON data I think this is due to the fact that there is no connection to the database server in postgresql. But, I've already tried adding addresses to ALLOWED HOSTS. I changed both the database and Django. P.S. The username, passwords and addresses are not real. $ cat node_modules/react-scripts/config/webpackDevServer.config.js ... // want to allow setting the allowedHosts manually for more complex setups allowedHosts: disableFirewall ?

Add an http GET/POST entry point to a Django with channels websocket
I'm new in Django and I'm building a site for booking. I build the front-end in vue 3 and the back-end in django using channels. I've implemented the websockets but now I'm trying to add a GET or POST entry point for the confirmation via link (like "url/api/confirm/confirm_code" or "url/api/confirm/confirm_code=code") in a mail I sent from the back-end. The problem is that my back-end never receive the request. I tried like this: app_name.urls from django.contrib import admin from django.urls import path, include urlpatterns: list[path] = [ path('admin/', admin.site.urls), path('api/', include('app.routing')), ] app.routing from django.urls import path from app.consumers.view import ViewConsumer from app.consumers.booking import BookingConsumer from app.consumers.account import AccountConsumer from app.consumers.profile import ProfileConsumer from app.http.confirm_reservation import confirm_reservation websocket_urlpatterns = [ path(r"ws/view/", ViewConsumer.as_asgi()), path(r"ws/booking/", BookingConsumer.as_asgi()), path(r"ws/account/", AccountConsumer.as_asgi()), path(r"ws/profile/", ProfileConsumer.as_asgi()), ] urlpatterns = [ path(r"confirm/<str:confirm_code>/", confirm_reservation, name="confirm_reservation"), ] app.http.confirm_reservation from django.http import JsonResponse from app.services.booking import BookingService def confirm_reservation(request, confirm_code: str): print(request) print(confirm_code) return JsonResponse(BookingService().confirm_reservation(request)) Least but not last, if you have any suggestions for a better code than I wrote, please tell me in a comment. Thanks. I'm using my own site and postman (http://192.168.1.5:8080/api/confirm/1234/) to try sending the confirmation code but the front-end get "Cannot GET /api/confirm/1234/" and the back-end doesn't … -

django allauth settings.SOCIALACCOUNT_ENABLED overwritten?
django-allauth provides a seettings parameter SOCIALACCOUNT_ENABLED that is used in urls.py to add conditionally socialaccount urls: allauth/urls.py: if app_settings.SOCIALACCOUNT_ENABLED: urlpatterns += [path("social/", include("allauth.socialaccount.urls"))] in html templates there is the same parameter used e.g. in allauth/templates/account/login.html: {% if SOCIALACCOUNT_ENABLED %} {% include "socialaccount/snippets/login.html" with page_layout="entrance" %} {% endif %} BUT: in templates it does not reflect settings.SOCIALACCOUNT_ENABLED but is taken from the apps.is_installed status: allauth/app_settings.py: class AppSettings(object): .... @property def SOCIALACCOUNT_ENABLED(self): return apps.is_installed("allauth.socialaccount") .... That means in summary: settings.SOCIALACCOUNT_ENABLED -> effect on included allauth url patterns settings.INSTALLED_APPS[..., 'allauth.socialaccount'..] -> effect on html templates {% if SOCIALACCOUNT_ENABLED %} Can anyone explain why this makes sense?? It did cost me quite some time to understand why templates do not react on "normal" settings parameter. -
How to open specific Accordion item in Django using Bootstrap?
I have a Django app with a page that contains a Bootstrap Accordion. I have a form in the third accordion item. On submit within that form I want the page to refresh to the same accordion item - I have some feedback messaging there that want to display to the user. Currently on Submit the page refreshes to the default item - in my case that's the first accordion item. I have tried appending /#collapseThree to the url, but the page refreshes to the default view.

Unable to get SaaS data for tenant using django-tenants, showing all data not tenant specific data
I am building a web application using django-tenants and have followed the documentation thoroughly, but still having issues showing data for a tenant specific to its subdomain and schema.
