Django Channels Daphne Maximum Simultaneous Connection

How make a reservation system in django
I am making a delivery date and time reservation system in django and there I need to implement a reservation system of time and date for the users. see this UI image here for better understanding I have to make such a kind of thing that if a user reserves a specific time lets say 9 AM on a specific date and places an order, then that particular time related to that particular date that the user placed an order on will get disabled so that no other user can place an order on that same date and time. Now, the problem is I am not very sure how to design the database relationships for this feature. Initially I'm thinking of this model design below but I'm sure that it's not that much efficient. class Date(models.Model): date = models.DateField() class Time(models.Model): time = models.TimeField(auto_now=False, auto_add_now=False) date = models.ForeignKey('Date', on_delete=models.CASCADE) Let's assume that one of my users placed an order on 3rd of the month with a delivery time of 10 AM. So according to the system the time '10 AM' on 3rd of the month should get disabled for other users. But the time '10 AM' on other days of … -
Firebase Social Auth + Django
I am now creating a mobile app with Flutter + Django as backend. I am planning to use Firebase Authentication with FlutterFire, what I understand is that the user logged in/logged out information will then be at the Firebase database. What is the common practice to notify the other backend (in this case is Django) that the user has logged in? And then give access to certain feature in the app? Is it that we use callback given from FlutterFire and then use the generated token from Firebase as the token between our Frontend (Flutter) and Backend (Django)? Thank you -
How to run a function after adding an element to ManyToManyField in django
I'm writing an app which has users functionality, each user can follow another user to see his posts on a main view. My question is. Is there any clever way to trigger a notification when a new entry is added to followed_users? The code of a field that stores users that are followed by a user: followed_users = models.ManyToManyField( "self", verbose_name=_("followed users"), blank=True, symmetrical=False, related_name="followers", ) and a corresponding method in view to follow a user: def follow(self, request: Request, **_kwargs): followed_user = self.get_object() if request.user.followed_users.filter(id=followed_user.id).exists(): return Response({"detail": _("You already follow this user.")}, status=400) request.user.followed_users.add(followed_user) return Response() I know I can invoke a function which creates a notification in follow() function but it's not very elegant for me. -
Filter Model Object using Wild-Chars
I need to be able to filter using wildchars, for example: Surnames.objects.filter(surname="GR%FF%N") should return objects with the following surnames: GRIFFIN, GREFFTEN, GRAFFAIN, and so on. Now obviously filter doesn't recognise % as a wildchar but the code above should demonstrate what I need to do. I also wish to limit the number of results returned. How would you recommend I do this? -

The function can't return callable object from it
I created a function to return a list of categories from data base, however, Django just doesn/t see categories and as a result says it a syntax error in the statement and doen't return it.

Django simplejwt: How to add refresh token to dict?
I am using simplejwt to get an access and refresh tokens. In a view I need to create a dict, where the both will be stored as well as access token claims and another additional data. Everything works but by some reason when the refrsh token is added to dict, it returns its decoded value, but not the token. my views.py @csrf_exempt #@api_view(('GET',)) def check_token(request): token_refresh = RefreshToken.for_user(request.user) print('REFRESH', token_refresh) token = request.META.get('HTTP_AUTHORIZATION', " ").split(' ')[1] data = {'token': token, 'refresh_token': token_refresh} try: valid_data = TokenBackend(algorithm='HS256').decode(token, verify=False) data['uui'] = valid_data['user_id'] data['validUntil'] = valid_data['exp'] data['clientId'] = 'default' print(data) return JsonResponse(data) except ValidationError as v: print("Validation error", v) print('REFRESH', token_refresh) returns the token: 'REFRESH eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI...' but data object returns: {'token': 'eyJ0eXAiOiJKV1QiLCJhbGci...', 'refresh_token': {'token_type': 'refresh', 'exp': 1628664751, 'jti': '38f0e3a4d7bb452681834a6b149aa496', 'user_id': 'None'}, 'uui': 1, 'validUntil': 1628059131, 'clientId': 'default'} my ideal result: {'token': 'eyJ0eXAiOiJKV1QiLCJhbGci...', 'refresh_token': 'eyJ0eXAiOiJKV1QiLCJhbGciOiJIUzI...', 'uui': 1, 'validUntil': 1628059131, 'clientId': 'default'} -
Can I use the same @property on multiple models in django?
I want to define an @property once and use it on two different models. Is this possible? Example: Suppose I have two models, seller and buyer: class seller(models.Model): first_name = models.CharField(max_length=50) last_name = models.CharField(max_length=50) class buyer(models.Model): first_name = models.CharField(max_length=50) last_name = models.CharField(max_length=50) And I wish to add a property for the django admin interface to display both models: @property def display_name(self): return f"{first_name} {last_name}" Is there a way to define this property once, but use it for both models? -
Use Django ORM in multiprocess spawn process
i need to use the Django ORM in some spawned process using python multiprocess module. At this moment, this how i spawn the process: import multiprocessing with multiprocessing.get_context('spawn').Pool() as pool: pool.map(insert_to_db, args) Now, here is the issue: the function insert_to_db uses the django ORM to get some objects, check data consistency and save the new collected result to DB. Actually, i can't start the spawned process using fork context due to some unidentified deadlocks. My initial idea is to start a the process, inject the Django dependencies, and before doing the execution of the insert_to_db function execute the django.setup() to load all django things. Anyone is able to give me a solution? -

How to configure django standalone app to install automatically all sub apps?
Problem description I have django standalone app named django_codeserver. It can be loaded from my private package registry as a pip-package. My app contains about twenty sub-apps for example django_codeserver.headers, django_codeserver.genders etc. Current behaviour To register all models in my project which uses django_codeserver, I have to register all the sub applications in the parent project INSTALLED_APPS such as: INSTALLED_APPS = [ ...
