Sorting django-mptt record by complex string field as number
I'm using django-mptt to build a hierarchical structure. There is a field "task_id", that represents task id, in the following format "task.subtask.subtask", number of subtasks is infinite. To sort tasks, I'm using standard code order_insertion_by = ['task_id'] It works well, but the fields are sorted as string, i.e. 1.10, 1.2, 1.3, etc. How can I make them sort as a number instead, so it will go 1.2, 1.2, 1.10? -

Access request or request.user in celery task
I am trying to access request.user in django celery task function but it is unable to access as the function is not accepting any request instance, so How can I access it? @shared_task def run_everyday(): return 0 I have configured that celery function in settings.py to run every day like CELERY_BEAT_SCHEDULE = { "run_day": { "task": "blog.tasks.run_everyday", "schedule": crontab(hour=10, minute=5), }, } I tried by defining another function to return request as result but another function needs to pass the request already like @shared_task def run_everyday(): user = get_request_user() return 0 def get_request_user(request): return request.user It shows request is not defined so How exactly can I access it? Do I need to created a middleware to get the request.user in celery task view? If yes, will that be efficient? -

How to protect or secure API routes access Django Rest_framework? [duplicate]
I built my personal website with ReactJS on the client side and Django with Rest_framework for API, Django is serving staticfiles. My personal website has nothing crazy just one API that handles the email. If someone want to get in contact with me then they can fill the form with their email name etc, however. I was able to get access to that api by use typing in the url https:.//www.personalwebsiteurl.com/api/contact-by-email, see screenshot below. Ever since, i got hired as an intern at a small company working with MEAN Stack, i totally forgot most of Django workaround. Thus, how could i secure access to this api/route or if this could potentially cause a security incident on my website? Thank you in advance, not necessarily looking for an a solution with the code but rather than a guide to come up with solution this is my urls.py under api module this is my urls.py under the server -

Django/DRF GET list of objects including object with FK to that object
I have an API endpoint that returns a list of objects (Orders). class Order(models.Model): item_name = models.CharField(max_length=120) Each of these Orders also has multiple associated Statuses, which acts similar to tracking the location of a package. A new one is created whenever the status changes, with the new status and a timestamp. class OrderStatus(models.Model): status = models.CharField(max_length=30) timestamp = models.DateTimeField(auto_now_add=True) order = models.ForeignKey(Order, on_delete=models.CASCADE, related_name="order_statuses") When I query a list of the current Orders, I want to return the most recent OrderStatus associated with it. Such as this: { "count": 2, "next": null, "previous": null, "results": [ { "item_name": "Something", "order_status": { "status": "Processing" "timestamp": "2023-09-25T12:31:12Z" } }, { "item_name": "Other Thing", "order_status": { "status": "Completed" "timestamp": "2023-08-15T10:41:32Z" } } ] } I have tried using prefetch_related() in my View, but that seems to be for the reverse situation (When the query is for the object that has the FK in it's class definition - which here would be if I wanted to list the fields on Order when I query for the OrderStatus). -
Google Charts - Very Slow Loading Time
I'm relatively new to web development and I like the look of Google Charts. I wanna load some Django data with it, but the load time is extremely slow. I have a simple chart here with only a single point. It takes 3-5 seconds to appear, after everything else on the webpage has already shown up. Am I doing anything wrong or could something be causing the lag? // chart google.charts.load('current', {packages: ['corechart', 'line']}); google.charts.setOnLoadCallback(drawBasic); function drawBasic() { var data = new google.visualization.DataTable(); data.addColumn('date', 'Year'); data.addColumn('number', 'Msgs'); data.addRow([new Date('2023-08-25'), 5]) var options = { hAxis: { title: 'Time' }, vAxis: { title: 'Number of Messages' }, backgroundColor: '#2C2F33' }; var chart = new google.visualization.LineChart(document.getElementById('chart_div')); chart.draw(data, options); } Thank you. -
Django - Any ideas on how to mimic the way Amazon handles their progress bar? [closed]
I have tried using Bootstap, which can produce a strait line. But I like the way Amazon's progress bar has node bubbles that show a checkmark in them when it reaches a certain point. I have considered just using a preset image, but if I have like 6 nodes minimum, with multiple options that those nodes can be, that can be a lot of image files. And if something were to change in the flow, it could potentially be a lot of work to update these files. So looking for an alternative -

WebSocket with Django and Expo not working
I am building an expo app that uses Django for backend. For the app I need to use WebSocket. But when I try to connect to the WebSocket on my Django project, I get Not Found: /ws/ [25/Sep/2023 19:34:58] "GET /ws/ HTTP/1.1" 404 2678 This is my Expo code: const socket = React.useRef(new WebSocket('ws://myIP:8000/ws/')).current; console.log(socket) if (socket) { // Now you can safely work with the WebSocket object } else { console.error('WebSocket is undefined.'); } socket.onmessage = (event) => { console.log(event.data) // Handle incoming messages from the WebSocket server }; socket.onopen = () => { // WebSocket connection opened console.log("opened") }; socket.onclose = (event) => { // WebSocket connection closed }; socket.onerror = (error) => { // Handle WebSocket errors console.log("error") }; This is my Django code: settings.py INSTALLED_APPS = [ 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', 'home', 'channels', ] ASGI_APPLICATION = 'API.routing.application' routing.py from channels.routing import ProtocolTypeRouter, URLRouter from django.urls import path from .consumers import YourWebSocketConsumer from django.core.asgi import get_asgi_application os.environ.setdefault("DJANGO_SETTINGS_MODULE", "API.settings") application = ProtocolTypeRouter({ "http": get_asgi_application(), "websocket": URLRouter( [ path("ws/", YourWebSocketConsumer.as_asgi()), # Add more WebSocket consumers and paths as needed ] ), }) consumers.py from channels.generic.websocket import AsyncWebsocketConsumer import json class YourWebSocketConsumer(AsyncWebsocketConsumer): async def connect(self): await self.accept() async … -
Migrating an application with subdomains to a single URL
I currently have an application that uses django-tenants with subdomains for each tenant (tenant1.domain.com, tenant2.domain.com...) It uses individual authentication, the auth models are in the schemas So my question is: Is it possible to migrate to a single URL model both for authentication and navigation? I tried many solutions, some managed to authenticate my user, but none managed to make me navigate in a tenant using a "schema-free" URL In short none maintained/created a session
