Getting Maximum date from Django Model Query
Hello I have a Student model in Django which has following fields Id, Status, Marks, End Date. When I am doing following query- records = list(Students.objects.filter(status__in=["Active"]) .values('id', 'marks', 'end_date') Then this is the value that I am getting - [{'id':'450', 'marks':'30', 'end_date':datetime.datetime(2021, 2, 3, 0, 0, tzinfo=<UTC>)}, {'id':'450', 'marks':'60', 'end_date':datetime.datetime(2021, 2, 7, 0, 0, tzinfo=<UTC>)}, {'id':'450', 'marks':'80', 'end_date':None}, {'id':'452', 'marks':'51', 'end_date':datetime.datetime(2021, 3, 1, 0, 0, tzinfo=<UTC>)}, {'id':'452', 'marks':'27', 'end_date':datetime.datetime(2021, 3, 3, 0, 0, tzinfo=<UTC>)}] Now, my requirement is to get sum of all marks and max date for same Ids. For exa for above result set the output that I want is this - [{'id':'450', 'marks':'170', 'end_date':datetime.datetime(2021, 2, 7, 0, 0, tzinfo=<UTC>)}, {'id':'452', 'marks':'78', 'end_date':datetime.datetime(2021, 3, 3, 0, 0, tzinfo=<UTC>)}] I have tried the following code to get this output - records = list(Students.objects.filter(status__in=["Active"]) .values('id', 'end_date') .annotate(marks=Coalesce(Sum('marks'), 0), )) Above code is giving me sum value but I am not able to get Max date. I tried adding end_date=Coalesce(Max('end_date__date'), 0) into annotate function but this is throwing this error - AttributeError: 'str' object has no attribute 'tzinfo' Anyone have idea how to get the Max date using annotate method or is there any other way of doing it?

Is this view in django secure?
I am building a RESTAPI in Django using the following library called drf-firebase-token-auth. The client sends a get request with the token_id available in the Authorization header, and the library is expected to handle authentication in Firebase automatically. But the problem is if I do a simple get request without headers like curl <url+endpoint> the library doesn't verify if there's a an Authorization header and try to get a token for verification as if the request happens successfully as if drf-firebase-token-auth didn't raised it to be a problem. So I handled an exception whereas if the get request doesn't have an an authorization header, then raise an exception. But is it secure? from datetime import datetime from rest_framework import status from rest_framework.decorators import ( api_view, ) from rest_framework.response import Response # Create your views here. @api_view(["GET"]) def check_token(request): # if token is valid response with current server time try: if request.META["HTTP_AUTHORIZATION"]: date = datetime.now() return Response( data="Server time is: " + str(date), status=status.HTTP_200_OK ) except: return Response(data="Authorization header unavailable") -

I have shown many posts in StackOverflow that those developer using "django-livesync" module to reload the pages and I tried same way but it's not reloading when I change any files.

The right architecture to create a semi Jupiter notebook clone with Django and React
I am building a web app that lets a user upload a dataset and apply many data science procedures and tasks like EDA, data processing, visualization, and creating models. You can imagine it as a dashboard for repetitive data science tasks so it will be event-based like button clicks so on and not like Jupiter notebook way. So my question is, how to manage such a work flow? after a user uploads a document (dataset) many requests will take place to transform and apply a new action on the data, as the procedure might take a long time due to the long processing time, is there an efficient way/architecture to design such a system? and how to handle many operations on the same file without I/O errors? I have come across Django Channels and it seems to be a good solution since it provides async/sockets-based connections that will give enough time for each request and not be bounded by the http timeout. One workflow that is going to take place in the project is the following: - upload dataset - get all columns - get datatypes - get dataset description/info - modify datatypes - create new column set - agg … -

Django - permissions depends on subscription type
I make a project with subscription functionality. So users can choose from such subscriptions: Starter Premium Super etc. So when they use Payment Widget and server gets callback with successful status of payment I need to change "Role" or "Group" for this user in some "Permissions Model". So I consider it like a separate model with a user as a foreign key. So it looks like: User model: username password is_active Permissions model: username (Foreignkey to User model) some permission some another permission As example, every user can create an object of Apartment model. It looks like: Apartment model: full address short address So I want to limit users in creating this objects. E.g. user with "Starter" status can add only 2 apartments, "Premium" - 5 apartments and "Super" - 10 apartments objects. So that's very simple example of how permissions should work. How can I achieve such functionality? I know that Django has Roles and Groups, but is it appropriate for my goals? -

How to stop Django from hanging after page refresh using channels?
Using channels it connects properly when the page loads the first time but then hangs on refresh. Not sure why this is happening. I've placed the code below to see what might be happening? # index.html <script> let socket = new WebSocket('ws://127.0.0.1:8001/ws/'); socket.onmessage = () => { console.log("Connected"); }; socket.onclose = () => { console.log('Websocket closed'); } </script> # app/consumer.py from json import dumps from time import sleep from channels.generic.websocket import WebsocketConsumer class WSConsumer(WebsocketConsumer): def connect(self): self.accept() self.send(dumps({'message': 'connected'})) for i in range(1000): self.send(dumps({'message': i})) sleep(2) #app/routing.py from django.urls import path from app.consumers import WSConsumer ws_urlpatterns = [ path('ws/', WSConsumer.as_asgi()) ] #core/asgi.py from channels.auth import AuthMiddlewareStack from channels.routing import ProtocolTypeRouter from channels.routing import URLRouter from django.core.asgi import get_asgi_application from app.routing import ws_urlpatterns os.environ.setdefault("DJANGO_SETTINGS_MODULE", "core.settings") django.setup() application = ProtocolTypeRouter({ "http": get_asgi_application(), "websocket": AuthMiddlewareStack(URLRouter(ws_urlpatterns)), }) # core/urls.py ... path('test/', views.IndexView.as_view()), ... In my settings I've added channels just below the .sites app but above everything else and I've added the ASGI_APPLICATION and running the application with python manage.py runserver 127.0.0.1:8001 -
Django multiple reshresh from view
