How to use both simple jwt token authentication and BasicAuthentication?
I have an DRF api and I have implemented the simplejwt authentication system. It works well. It is usefull when I want to connect my api from external script (I don't need to store credential and just use the token). However I also want to be able to use the DRF interface login when i reach my api from browser so I have implemented also the Basic and SessionAuthentication. Is it the good way to do that ? in my settings.py REST_FRAMEWORK = { 'DEFAULT_AUTHENTICATION_CLASSES': [ 'rest_framework_simplejwt.authentication.JWTAuthentication', 'rest_framework.authentication.BasicAuthentication', 'rest_framework.authentication.SessionAuthentication', ] } SIMPLE_JWT = { 'ACCESS_TOKEN_LIFETIME': timedelta(days=1), } in my api views.py from rest_framework.permissions import IsAuthenticated from rest_framework.authentication import SessionAuthentication, BasicAuthentication from rest_framework.decorators import permission_classes, authentication_classes # Create your views here. @api_view(['GET']) #@authentication_classes([SessionAuthentication, BasicAuthentication]) @permission_classes([IsAuthenticated]) def get_all(request): # as a token is used, the user with this token is know in the requets user = request.user # show only mesures of user having the token provided mesures = Mesure.objects.filter(user_id=user.id) serializer = MesureSerializer(mesures, many=True) return Response(serializer.data) In my urls.py from rest_framework_simplejwt.views import TokenObtainPairView, TokenRefreshView urlpatterns = [ path('mesures/', views.get_all), path('mesure-add/', views.add_mesure), path('token/', TokenObtainPairView.as_view(), name='obtain_tokens'), path('token/refresh/', TokenRefreshView.as_view(), name='refresh_token'), path('api-auth/', include('rest_framework.urls')) ] As you can see I had to comment the @authentication_classes decorator to … -

Running Django in IIS
I have a Python application that's that has been working correctly as backend for my website, up to now I have been running it using "python manage.py runserver IP:8000" in CMD. However I would like it to start using HTTPS, but when I try to access through my browser on https://IP:PORT I get the following error: You're accessing the development server over HTTPS, but it only supports HTTP. The server I am running all of this is a Windows Center 2019 DataCenter, normally on a linux environment I would just use NGINX+GUNICORN. I was browsing possible solutions and stumbled upon this, however I already am using IIS to host a website (My frontend), so I needed to figure out how to host several websites for the same IP, I have now found this. Long story short, I configured the new IIS website for it to access my django, I then changed the hostname since both frontend and the new backend will using the same ip and ports (80, 443).

Authentication with Microsoft Azure AD in a multi-tenant app
Following the documentation, registered an application with Accounts in any organizational directory. The Tenant where the application resides is in "Default Directory" and has only one user, tiagomartinsperes@gmail.com. Also, the app has user assignment (as pointed out here) set to No After, created another Tenant (different directory) and invited the external user me@tiagoperes.eu. That's the user I'm getting troubles logging into the previously created app. Then, enable the OAuth2 support using social_core.backends.azuread.AzureADOAuth2 (from here). As I try to authenticate now, it works well with tiagomartinsperes@gmail.com but with me@tiagoperes.eu gives the following error Selected user account does not exist in tenant 'Default Directory' and cannot access the application 'a9a22676-8a1c-4297-95d3-8cd89553220e' in that tenant. The account needs to be added as an external user in the tenant first. Please use a different account. -
How do I affect a single looped element in Django html?
I'm building an app in Django, using Bulma for styling. I have a Polishes model that has a favorites field, which references the User (users can save polishes to their list of favorites): models.py: class Polish(models.Model): name = models.CharField(max_length=100) image = models.CharField(max_length=400, default="https://www.dictionary.com/e/wp-content/uploads/2018/02/nail-polish-light-skin-tone.png") brand = models.ForeignKey(Brand, on_delete=models.CASCADE, related_name='polishes') favorites = models.ManyToManyField(User, related_name='favorite', default=None, blank=True) def __str__(self): return self.name The add_favorites function checks to see if the polish has been added to the user's favorites already, and if it has, it removes the polish from the list. If it hasn't, it adds it: views.py: @ login_required def add_favorite(request, id): polish = get_object_or_404(Polish, id=id) if polish.favorites.filter(id=request.user.id).exists(): polish.favorites.remove(request.user.pk) else: polish.favorites.add(request.user.pk) return redirect('favorites_list') When I render the list of polishes, I'm using Bulma cards, displaying one polish per card. In the footer of the card, I want it to say 'Save to Favorites' if the polish is not in the user's list of favoties and 'Remove from Favorites' if it is. I'm struggling to get this piece to work. It will currently show either Save to Favorites or Remove from Favorites on all of the cards. Does anyone have any insight on how to render a different message only on those that are already … -

Django model foreign key cascade will not trigger delete
there two basic ways to do something when an instance gets deleted: Overwrite Model.delete Signal I used to reckon both of them serve the same purpose, just provides different ways of writing, but works exactly. However, in this occasion, I realise I was wrong: class Human(models.Model): name = models.CharField(max_length=20) class Pet(models.Model): name = models.CharField(max_length=20) owner = models.ForeignKey(Human, related_name="pet", on_delete=models.CASCADE) def delete(self, *args, **kwargs): print('------- Pet.delete is called') return super().delete(*args, **kwargs) h = Human(name='jason') h.save() p = Pet(name="dog", owner=h) p.save() h.delete() # nothing is shown Why Pet.delete Is not firing at Human.delete By the foreign cascade? Does I have to apply a signal on this? If so, would it cost more performance? I am building something very heavy, comment system, filter decent records and delete when the commented target get deleted, the comment model has many null-able foreign key fields, with models.CASCADE Set, only one of them is assigned with value. But in product delete view, I call product.delete Then triggers cascade, but comment.delete Is not firing. -

I downloaded and configured django-select2 and for some reason it looks disgusting not like it should be I check all settings and everything should be all right I guess its just some css files are not loading but in terminal everything`s good forms.py class WorkLogForm(forms.ModelForm): worklog_date = forms.DateField(label='Дата', widget=forms.DateInput( attrs={'type': 'date', 'class': 'form-control', 'placeholder': 'Введите дату'})) description = forms.CharField(label='Описание', widget=forms.Textarea(attrs={'class': 'form-control', 'placeholder': 'Описание'})) contractor_counter = forms.ModelChoiceField( queryset=CounterParty.objects.all(), empty_label='', widget=ModelSelect2Widget( model=CounterParty, search_fields=['name__icontains'], ) ) contractor_object = forms.ModelChoiceField( queryset=ObjectList.objects.all(), widget=ModelSelect2Widget( model=ObjectList, search_fields=['name__icontains'], ) ) contractor_section = forms.ModelMultipleChoiceField( queryset=SectionList.objects.all(), widget=ModelSelect2Widget( model=SectionList, search_fields=['name__icontains'], ) ) class Meta: model = WorkLog fields = ( 'worklog_date', ) template.html {{ form.media.css }} <style> input, select { width: 100% } </style> <div class="container"> <form action="{% url 'home' %}" method="post"> {% csrf_token %} <div class="container mt-5"> {{ form.as_p }} </div> <button type="submit">Создать</button> </form> </div> <script src="https://code.jquery.com/jquery-3.5.1.min.js" integrity="sha256-9/aliU8dGd2tb6OSsuzixeV4y/faTqgFtohetphbbj0=" crossorigin="anonymous"></script> {{ form.media.js }} -
ViewSet class variable
Now I have the following logic implemented for a GET request in Django Rest Framework: class SomeViewSet(mixins.ListModelMixin, GenericViewSet): count = None def get_queryset(self): query_set = ... # some_logic self.count = query_set.count() return query_set def list(self, request, *args, **kwargs): response = super().list(request, *args, **kwargs) response.data = {'count': self.count, 'data': response.data} return response That is, the queryset is calculated according to complex logic, and it may contain a different number of objects that need to be returned in a GET request, since I don’t have access to the query_set variable inside the list function and I don’t want to copy the query_set calculation logic, I decided do it with a class variable. But still, the feeling that this is not very correct does not leave. What other options are there? -
How to install the node in Dockerfile?
I want to install the node v18 in on AWS Linux Prerequisite I have Django and frontend React system. So, I want to use node when installing frontend. If I use make Dockerfile such as From node:18 it works, but I want to use FROM python:3.9 to django work. Is it not a good idea to put Djang and React in the same container? Now my docker file is like this. FROM python:3.9 ENV PYTHONUNBUFFERED 1 RUN apt-get update WORKDIR /usr/src/app RUN apt-get install -y npm RUN pip install pipenv WORKDIR /usr/src/app/frontend_react RUN npm install --force RUN node -v //version 12 is installed RUN dnf module install nodejs:18/common RUN node -v RUN npm run build Howeber there is no dnf. How can I do this? -
How to serialize Django model with 2 or more foreign keys?
I have two models in models.py: from django.db import models from django.contrib.auth.models import User class Course(models.Model): name = models.CharField(max_length=100) description = models.TextField() cost = models.IntegerField() course_image = models.ImageField() def __str__(self): return self.name class PurchasedCourse(models.Model): purchased_by = models.ForeignKey(User, on_delete=models.CASCADE) purchased_course = models.ForeignKey(Course, on_delete=models.CASCADE) purchased_time = models.DateField(auto_now_add=True, blank=True) def __str__(self): return str(self.purchased_by) + ' => ' + str(self.purchased_course) My serializers.py so far: from rest_framework import serializers from .models import * class CourseSerializer(serializers.ModelSerializer): class Meta: model = Course fields = '__all__' class PurchasedCourseSerializer(serializers.ModelSerializer): class Meta: model = PurchasedCourse fields = '__all__' (it is just simple serializing) My views.py: from django.http import HttpResponse from requests import Response from .models import * from .serializers import CourseSerializer, PurchasedCourseSerializer from rest_framework import generics, viewsets from rest_framework.authentication import BasicAuthentication, TokenAuthentication from rest_framework.permissions import IsAuthenticated class CourseViewSet(viewsets.ModelViewSet): authentication_classes = [TokenAuthentication] permission_classes = (IsAuthenticated,) queryset = Course.objects.all() serializer_class = CourseSerializer class UserRelatedCourseViewSet(viewsets.ModelViewSet): queryset = PurchasedCourse.objects.all() serializer_class = PurchasedCourseSerializer def get_queryset(self): return PurchasedCourse.objects.filter(purchased_by__username=self.request.query_params['username']) So, question is how to get all Course objects(with all fields) that depends only on logged in user using PurchasedCourseSerializer? -
Django choosing which model to use in Django admin
I have three models models.py class Cluster(models.Model): blockOption= (('IMG', 'IMG'),('DESC', 'DESC'),) block = models.CharField(max_length= 100, choices=blockOption) order= models.IntegerField(null=True) post = models.ForeignKey(Post, verbose_name=('Link to Post'), on_delete=models.CASCADE) class Image(models.Model): src = models.ImageField(verbose_name=('Imagefile')) captions= models.CharField(max_length= 100, null=True) cluster = models.ForeignKey(Cluster, verbose_name=('Link to Post'), on_delete=models.CASCADE) class Description(models.Model): text=models.TextField(max_length=400) cluster = models.ForeignKey(Cluster, verbose_name=('Link to Post'), on_delete=models.CASCADE) and in admin.py class ImageAdminInline(TabularInline): extra = 1 model = Image class DescriptionAdminInline(TabularInline): model= Description @admin.register(Cluster) class ClusterAdmin(admin.ModelAdmin): inlines= (ImageAdminInline, DescriptionAdminInline) I have put ImageAdminInline and DescriptionAdminInline as inlines to ClusterAdmin. I' m planning to use ClusterAdmin to choose which admin I would be using. I hope it will be something similar to wagtail's streamfield(image above). Is there any solution that I could use without overriding admin template? I have tried using Ajax to just hide or show inlines but it was my first time to override django's template so it failed.
