How can I access the IIS `REMOTE_USER` environment variable inside of an httpPlatformHandler process?
Background I am trying to set up a Django application to use Windows Authentication via IIS. The Django documentation says that you can authenticate with the REMOTE_USER environment variable set by IIS. We deploy our Django applications via httpPlatformHandler, which requires that any environment variables be declared outright in order to be passed. I'm assuming this is also the case with the REMOTE_USER because when I print os.environ.get("REMOTE_USER"), it's None. Question Does anyone know of a way to dynamically pass the REMOTE_USER environment variable through to the httpPlatform process? Is that even the right way to approach it? I'm assuming the environment variable would change for each user that attempted to access the process, am I barking up the wrong tree entirely? Things I've Tried I've tried setting an environment variable to be <environmentVariable name="REMOTE_USER" value="%REMOTE_USER%" /> But that just sets it to be literally %REMOTE_USER%, which is not what we want. I've also tried %HTTP_REMOTE_USER% which doesn't work either. I've tried setting forwardWindowsAuthToken to true, but that just adds an unrelated header that Django isn't looking for. Any help, suggestions, or anything would be greatly appreciated! -
django login doesnt redirects without refresh the page
Im a frontend developer and Im working on a login page with a backend team that uses Django. in my login.html file there is a form that gets phone number and password from user. Im getting the user inputs from the from through javascript and after validation send it to backend through a fetch request. but there is a problem. the backend guy said that:"I get the phone number and password correctly through your request and redirects the page to the new url if password and phone number was true and Django redirects correctly but the browser doesnt go to the new page and I should refresh the browser. when I refresh the browser it goes to the new page correctly". I searched in stackoverflow and checked similar Django redirect issues but none of them was my problem. I also asked Gemini but it didnt give me any good response. I provide both Django redirect code and my Javascript and html code: // ================================================ from validation: const form = document.querySelector("form"); const phoneRegEx = /^09\d{9}$/; const formData = new FormData(); form.addEventListener("submit", (event) => { event.preventDefault(); const phone_value = document.querySelector(".phone").value; const passwordValue = document.querySelector(".password").value; document.querySelector(".phone").classList.remove("notValid"); document.querySelector(".password").classList.remove("notValid"); document.querySelector(".password-empty-error").style.display = "none"; document.querySelector(".phone-empty-error").style.display = "none"; … -
Why an HTML/ JS Button is working on PC browser but not on mobile devices?
I am developing a django web app, and I have a particular button which is for purchasing a subscription through stripe. the button is working fine on PC and desktop browsers, but not on mobile devices (Iphones). I tried to enable pop-ups, but it didn't work. this is the code below: <style> .subscription-container { display: flex; justify-content: space-around; margin-bottom: 20px; } @media screen and (max-width: 768px) { .subscription-container { flex-direction: column; } } </style> <script> console.log("Sanity check!"); // Get Stripe publishable key fetch("/sciences/config/") .then((result) => { return result.json(); }) .then((data) => { // Initialize Stripe.js const stripe = Stripe(data.publicKey); // Event handler for 14-day subscription document.querySelector("#submitBtn14").addEventListener("click", () => { // Get Checkout Session ID for 14-day subscription fetch("/sciences/create-checkout-session/") .then((result) => { return result.json(); }) .then((data) => { console.log(data); // Redirect to Stripe Checkout return stripe.redirectToCheckout({sessionId: data.sessionId_14day}) }) .then((res) => { console.log(res); }); }); // Event handler for 1-day subscription document.querySelector("#submitBtn1").addEventListener("click", () => { // Get Checkout Session ID for 1-day subscription fetch("/sciences/create-checkout-session/") .then((result) => { return result.json(); }) .then((data) => { console.log(data); // Redirect to Stripe Checkout return stripe.redirectToCheckout({sessionId: data.sessionId_1day}) }) .then((res) => { console.log(res); }); }); }); </script> </head> <!DOCTYPE html> <html> <head> <meta charset="utf-8"> <meta name="viewport" content="width=device-width, initial-scale=1"> … -

If POST request are csrf protected by default What is the purpose of @method_decorator(csrf_protect) in Django?
I think all POST, PUT, DELETE requests is CSRF protected by default in DRF, But I saw in some tutorial videos that they are using @method_decorator(csrf_protect) on some class-based views with POST and DELETE request, so I did it same. But now I'm thinking what is the purpose of doing that when these request is CSRF protected by default? @method_decorator(csrf_protect, name='dispatch') class LogoutView(APIView): def post(self, request, format=None): try: auth.logout(request) return Response({'success': 'Logged out.'}) except Exception as e: print(e) return Response({'error': 'Something went wrong.'}) -

Why does django continue to use the old admin namespace alongside the new custom admin url?
I'm developing a django app. I wish to change the admin url with an environment variable. Here is how I retrieve it in urls.py: import os admin_url = os.getenv('SUPERUSER_URL', 'custom-admin/') # Default is 'custom-admin/' if no key is set # Also, the environment variable has a slash at the end In the urlpatterns it is defined as such: urlpatterns = [ path(admin_url, admin.site.urls), # more views... ] Whenever I try to access my admin panel, I can do so with no issue using the new name. But the issue is two things: Once I have accessed the admin panel, anytime I try to access a model linked to the panel, it will redirect to the url that django's original admin namespace associates it self with. E.g. admin/users instead of custom-admin/users The second issue is that I can still access the admin panel using the original name 'admin' I am not using any custom admin template, I simply have defined a bunch of models to be used with the admin site in admin.py. Here's a snippet of my admin.py file, in case you need to see how I'm implementing them: from django.contrib import admin from .models import User, Foo from django.contrib.auth.admin … -

How To Order Alphanumeric CharFields in Django
i have a model for menu items that has a CharField for the numbers as some of them have sub variants that have a letter suffix fx. 25, 26, 27, 27a, 28... how do i order the objects after the menu number with the suffix taken into account after? so this list [1g, 14, 2g, 27a, 27, 33, 33b] would be [1g, 2g, 14, 27, 27a, 33, 33b] when just using order_by it defaults to the first number so [27, 4 0, 27a] comes out as [0, (2)7, (2)7a, 4] -

Navigating through apps in django
After spending one full day trying to fix this problem, I finally ask here. Sorry if this is obvious to the Django purists! I have this project with (currently) 2 apps, called intro and rules. The intro app contains a button that should redirect to rules. Currently, for some reason that I cannot understand, clicking the button redirects to the intro page itself. Does someone see the mistake here? Following are the relevant code parts: HTML template for the button: <div class="button-container" action="{% url 'rules:index' %}"> <form class = "Demo_questionnaire""> {% csrf_token %} <button type="submit">New game</button> </form> </div> Project settings: INSTALLED_APPS = [ "django.contrib.admin", "django.contrib.auth", "django.contrib.contenttypes", "django.contrib.sessions", "django.contrib.messages", "django.contrib.staticfiles", 'intro', 'rules', ] URL configuration for the project: urlpatterns = [ path("admin/", admin.site.urls), path("intro/", include("intro.urls", namespace="intro")), path("rules/", include("rules.urls", namespace="rules")), ] URL configuration for intro: app_name = "intro" urlpatterns = [ path("", views.index, name="index"), ] URL configuration for rules: app_name = "rules" urlpatterns = [ path("", views.index, name="index"), ] Thank you in advance, and sorry if the answer is obvious :( -
Django: using two related fields / foreign keys at once
I have three models: class Team(models.Model): team_id = models.AutoField() team_name = models.CharField() class Game(models.Model): game_id = models.AutoField() home_team = models.ForeignKey(Team, on_delete=models.CASCADE) away_team = models.ForeignKey(Team, on_delete=models.CASCADE) class TeamBoxScore(models.Model): game = models.ForeignKey(Game, on_delete=models.CASCADE, related_name='game_boxscore') team = models.ForeignKey(Team, on_delete=models.CASCADE, related_name='team_boxscore') # some stats here What I want to do is, for every Game instance, access the TeamBoxScore that matches both the Game instance and the Team instance referenced by home_team/away_team. Is there a way that I can have game.home_team.team_boxscore reference only the boxscore for that game_id? Or, conversely, can I specify which game.game_boxscore I want to return (the one that matches home_team or the one that matches away_team)? I want to minimize queries and avoid long iterative solutions. I've tried annotating the fields from each TeamBoxScore instance to every Game (referencing the game_boxscore related field), but that ends up doubling the size of the queryset and placing the values from the home boxscore and the away boxscore in separate instances. I've tried going through the team_boxscore related field, but that returns every boxscore for that team (game.home_team.team_boxscore). I've further tried to groupby these annotated values and just return the sum, but this is both inelegant and takes too long (and could be wrong!) … -
Django believes that there is a "SuspiciousFileOperation". This is not true

Is it possible to add a "InputField" in ChoiceField in Django?
I'm in the process of developing a form that aligns with a database model. One of the fields in this form requires users to select from a range of options. Initially, I implemented this using Django's ChoiceField. However, I'm exploring the possibility of allowing users to input their own option if it's not available in the predefined choices. Is there a way to integrate this?
