Azure App Service web app: Django + Microsoft login redirect HTTPS issue
Azure App registration web redirect URL (it's HTTPS) as below: Using Azure App Service deployed the Django web app successfully: the above deploying result shows http://, but in Azure web app web it shows https://, also could open the web app using https successfully with valid as below: But when the web app redirected to Microsoft site to login, it uses http:// again which doesn't match the https:// configured in App registration: The MS authentication and redirection is handled by package ms_identity_web, code provided from https://github.com/Azure-Samples/ms-identity-python-django-tutorial/tree/main/1-Authentication/sign-in In development environment there is no issue since I use http://localhost:8000/auth/redirect as web redirect url in App registration. My issue could be the same as this one: link, but it covered the URL details so not sure if it was the same http/https mismatching issue. -

Add Django super user token in http request
I use Django (as backend and frontend) for a website. I want to create http request with the condition (of use) to be Django super user. But I don't know how to add in the headers the token (or the proof that the user that uses the request is a super user). I tried this with the csrf token : First I use the {% csrf_token %} in the template. <form action="#" id="admin-add-event" method="POST"> {% csrf_token %} ... <button type="submit" id="admin-submit">Add event</button> </form> const url = `${window.BASE_URL}events/`; const form = document.getElementById('admin-add-event'); const data = { ... } let xhr = new XMLHttpRequest(); xhr.open('POST', url , true); xhr.setRequestHeader('X-CSRFToken', form.elements.csrfmiddlewaretoken.value); xhr.setRequestHeader("Content-Type", "application/json"); xhr.onload = function () { ... } xhr.send(JSON.stringify(data)); And in the Django view of the endpoint : @api_view(['GET', 'POST']) def all_events(request): if request.method == 'POST': if not request.user.is_superuser: return Response(status=status.HTTP_401_UNAUTHORIZED) # etc ... But the check of super user fails always I precise that I don't want to implemente a user system. I want to use the system of super user of Django. Thanks in advance ! -
How to use Django ImageField to upload to Google Cloud Storage instead of local
I want to use Django's ImageField on a model so people can upload a logo. I found the ImageField however reading from the docs it says Django stores files locally, using the MEDIAROOT***andMEDIAURL** settings.py I'm wondering how I can change the *upload_to= behavior to upload to a gcp bucket instead? If it's possible when I call .save what is saved to the database, the gcp bucket url? From reading the docs it doesn't say one way or the other if this is possible or if all images should be stored locally where the service is being ran. I have thought of saving the binary images directly to the db but that seems inefficient. -

Django reverse() behind proxy
My Django REST API is deployed behind an API Gateway (Kong). I want to reserve() some urls in my APIViews. I would like to ask for help to get the right url format. Based on basepath of the API gateway. Communication flow: Client (requesting basepath) <-> Kong (forwarding to upstream) <-> Apache (Reverse Proxy) <-> Django Kong defines a basepath and an upstream to forward client request to Django. Kong includes X_FORWARDED_HOST and X_FORWARDED_PATH in the HTTP header. X_FORWARDED_PATH contains the basepath of the gateway. X_FORWARDED_HOST contains the gateway-url. Gateway basepath is: /gateway-basepath Upstream path is: mydomain.com/py/api/v1 Basically, without gateway, Django reverse() creates following url for users endpoint: mydomain.com/py/api/v1/users/ With the API gateway, the Django creates follow path: apigatewayurl.com/gateway-basepath/py/api/v1/users/ Django is considering X_FORWARDED_HOST, but not X_FORWARDED_PATH I need following result: apigatewayurl.com/gateway-basepath/users Otherwise the Django url resolving is not usable within the api gateway. I would appreciate any help. urls.py from rest_framework.views import APIView from rest_framework import routers from . import views class APIRootView(APIView): def get(self, request, format=None): return Response({ 'users': reverse('user-list', request=request, format=format), }) router = routers.DefaultRouter() router.register(r'users', views.UserViewSet) urlpatterns = [ path('api/v1/', APIRootView.as_view(), name="api_root"), ] urlpatterns += router.urls views.py from rest_framework import viewsets from django.contrib.auth import models as django_models … -

How can I modify attributes of objects in a Django queryset for data presentation without modifying the original object?
I want to present a list of objects for which I want to filter/modify one attribute during the presentation of the data. Something close to an annotation, but I did not manage to do it with annotations. These are the models class Airline (models.Model): name = models.CharField() destinations = models.ManyToManyField("city") customers = models.ManyToManyField("user") class City (models.Model): name = models.CharField() country = models.CharField() class User (models.Model): name = models.CharField() preferredDestinations = models.ManyToManyField("city") I want, for a given user, present a list of the Airlines the user is customer, and for each Airline present the list of destinations for the Airline. But instead of presenting all the airline destinations I only want to present the destinations preferred by the user. e,g, Airline1.destinations=["New York", "London", "Paris", "Madrid] Airline2.destinations=["Madrid", "Barcelona", "Rome", "Berlin", "London"] User1.preferredDestinations=["Madrid", "Barcelona", "Paris"] With user1 being a customer of Airline1 and Airline 2, I want the page to present a table showing to which of the user preferred destination every airline flies to. I.e. I do not want to see all the destinations the airline flies to, only the ones the user is interested: E.g. Welcome User1! These are your airlines that fly to your preferred destinations Airline | Destination | … -
DJANGO: replace a combobox created successfully in a list of views.py, with one created with classes in forms.py?
I'm new to Django. I saw that there are 2 different ways to create comboboxes and forms. I would like to replace my current mode, already successfully created, with another mode. WAY 1 (works well, correctly): I have a combobox that works fine, created by putting the items in a list in views.py, for example: color_choices = ("Red","Blue","Black", "Orange"). I am currently using this mode. WAY 2: Way 1 works fine correctly for me, but only now I've seen that it's possible to create comboboxes also by creating a forms.py file, importing from django import forms, and then writing the items in the classes. The combobox uses a static list QUESTION: How can I modify my code (which uses Way 1) and replace it with forms.py with Way 2 classes? I would like to use the classes and the forms.py file, and I would not like to use the items in the views.py file (it works correctly fine with Way 1). Can you show me how I can use Way 2 correctly? Thank you all! Which of the two ways is more correct and better in terms of loading speed? Thank you all! P.S: comboboxes are database independent. they don't … -

Problem Despite following the steps outlined in the StackOverflow answer linked above, I'm getting the error 'NoneType' object has no attribute 'user' Code views.py views.py class MemberDetailView(LoginRequiredMixin, generic.DetailView): """View class for member profile page""" model = User context_object_name = 'user' def get_context_data(self, **kwargs): context = super().get_context_data(**kwargs,) context['form'] = JoinCommunityForm() return context class JoinCommunityFormView(FormView): """View class for join code for users to join communities""" form_class = JoinCommunityForm def get_form_kwargs(self, *args, **kwargs): form_kwargs = super().get_form_kwargs(*args, **kwargs) form_kwargs['request'] = self.request return form_kwargs def post(self, request, *args, **kwargs): """posts the request to join community only if user is logged in""" if not request.user.is_authenticated: return HttpResponseForbidden return super().post(request, *args, **kwargs) class MemberDashboardView(View): """View class to bring together the MemberDetailView and the JoinCommunityFormView""" def get(self, request, *args, **kwargs): view = MemberDetailView.as_view() return view(request, *args, **kwargs) def post(self, request, *args, **kwargs): view = JoinCommunityFormView.as_view() form = JoinCommunityForm(request.POST) if form.is_valid(): forms.py forms.py from communities.models import Community, UserRoleWithinCommunity class JoinCommunityForm(forms.Form): pin = forms.RegexField('^[A-HJ-NP-Z1-9]$', max_length=6, label='', widget=forms.TextInput(attrs={'oninput': 'this.value = this.value.toUpperCase()'})) … -
Getting error : django.db.utils.IntegrityError: UNIQUE constraint failed: auth_user.username || I'm a beginner trying to save in Djnago
I'm trying to learn django. Just started with a project. It has 2 applications so far. Employee poll I'm trying to do it via CMD. It shows the following issues. Actually I was trying to follow a tutorial for a django project. I checked, there is no UNIQUE keyword used in the code. I even tried deleting and then saving but didn't resolve. Employee :-- **models.py (employee) : ** from django.db import models from django.contrib.auth.models import User from django.db.models.signals import post_save from django.dispatch import receiver # Create your models here. class Profile(models.Model): user = models.OneToOneField(User, on_delete=models.CASCADE) designation = models.CharField(max_length=20, null=False, blank=False) salary = models.IntegerField(null=True,blank=True) class Meta: ordering = ('-salary',) #minus sign indicates that we need the result in decending order def __str__(self): return "{0} {1}". format(self.user.first_name, self.user.last_name) @receiver(post_save, sender=User) def user_is_created(sender, instance, created, **kwargs): if created: Profile.object.create (user=instance.) else: instance.profile.save() Poll :-- **models.py (poll)** from django.db import models from django.contrib.auth.models import User # Create your models here.` `class Question(models.Model): # models.Model is the base model. we just need to extend it. #All the class varibales will be considered as the columns of the table. title = models.TextField(null=True, blank = True) status = models.CharField(default = 'inactive', max_length=10) #if we don't pass … -
use django-filters on a queryset in the backend
Assuming I have a queryset and some filters I got from the front end, can I use the pre-defined FilterSet to filter over the queryset? example: models.py class User(models.Model): name = models.CharField(...) score = models.IntegerField(...) filters.py class UserFilter(django_filters.FilterSet): q = django_filters.CharFilter(method="text_search_filter") score_min = django_filters.NumberFilter(field_name="score", lookup_expr="gte") score_max = django_filters.NumberFilter(field_name="score", lookup_expr="lte") class Meta: model = User fields = {} def text_search_filter(self, queryset, name, value): return queryset.filter(name__icontains=value) views.py class UserView(View): filter_class = UserFilter ... def post(self, request, **kwargs): qs = User.object.all() filters = {"q": "john doe", "score_min": 5, "score_max": 10} Can I call UserFilter and pass the filter dict? To prevent me applying those filters again, since I already have those defined in the UserFilter Here's what I tried and didn't work: views.py def post(self, request, **kwargs): qs = User.object.all() filters = {"q": "john doe", "score_min": 5, "score_max": 10} filter = UserFilter(request.GET, queryset=qs) filter.is_valid() qs = filter.filter_queryset(qs) # Did not apply the filters
