Default HyperlinkedModelSerializer not finding the endpoints
I am trying to simply change my ModelSerializer to HyperlinkedModelSerializer to include the url to each of the objects listed in the ListView of the default Browsable API. According to the docs, since I am using default 'pk' for the lookup, I just change the class I inherit the serializer from: # class SeasonSerializer(serializers.ModelSerializer): class SeasonSerializer(serializers.HyperlinkedModelSerializer): # url = serializers.HyperlinkedIdentityField( # view_name='season', lookup_field='pk') ---> Not needed according to docs but have also tried with this class Meta: model = Season fields = ('id', 'url', 'years', 'active') And add the context when instantiating it in the view: class SeasonListView(APIView): def get(self, request, *args, **kwargs): queryset = Season.objects.all().order_by('years') serializer = SeasonSerializer( queryset, many=True, context={'request': request}) print('INFO: ', serializer) permission_classes = [ ] authentication_classes = [ ] return Response({"Seasons": serializer.data}) class SeasonDetailView(APIView): def get(self, request, *args, **kwargs): pk = kwargs['pk'] season = get_object_or_404(Season, pk=pk) serializer = SeasonSerializer(season, context={'request': request}) # print('Data: ', serializer.data) --> this breaks return Response(serializer.data) And my endpoints are the same as when using ModelSerializer: urlpatterns = [ path(r'seasons/', SeasonListView.as_view(), name='season-list'), path(r'seasons/<int:pk>/', SeasonDetailView.as_view(), name='season-detail'), ] The error is the following: For http://localhost:8000/api/seasons/1/ Exception Type: ImproperlyConfigured Exception Value: Could not resolve URL for hyperlinked relationship using view name "season-detail".

Setting up router with APIView and viewset in Django Rest Framework
It's my first question on Stackoverflow ! I'm new to Django and following some tutorials. I'm trying to understand if there is a way to set up the routing of an API from different view classes like APIView and viewsets.ModelViewSet (please tell me if I do not use the good wording) In views I have : from rest_framework import viewsets from post.models import UniquePost from .serializers import UniquePostSerializers from rest_framework.views import APIView class UniquePostViewSet(viewsets.ModelViewSet): serializer_class = UniquePostSerializers queryset = UniquePost.objects.all() class FileUploadView(APIView): some code here but no queryset nor serialized data...and no model In urls I have : from post.api.views import UniquePostViewSet from django.urls import path, include from rest_framework.routers import DefaultRouter from post.api.views import FileUploadView router = DefaultRouter() router.register('UniquePost', UniquePostViewSet, base_name='uniquepostitem') router.register('demo', FileUploadView, base_name='file-upload-demo') urlpatterns = router.urls But it seems that I can register FileUploadView this way. Because I don't have a queryset to render. I have : AttributeError: type object 'FileUploadView' has no attribute 'get_extra_actions' I realized that (well I think) that I can use APIView for FileUploadView (and add ".as_view()) but I think I have to rewrite UniquePostViewSet using APIView as well and defining exactly what I want to see in details like POST, PUT etc... My question … -

Django setup elasticsearch client with password auth
My Django application uses elasticsearch to index several ressources. Now I wanted to protect my elasticsearch instance with as password wich is working fine if I use "curl -u" or so.

Is smb. maybe able to pass show me some snippets of his configuration? My current state looks like this: settingy.py ELASTICSEARCH_DSL = { 'default': { 'hosts': env.str('ELASTICSEARCH_HOST') + str(':') + env.str('ELASTICSEARCH_PORT'), }, } ELASTICSEARCH_DSL_SIGNAL_PROCESSOR = 'django_elasticsearch_dsl.signals.RealTimeSignalProcessor' documents.py from django_elasticsearch_dsl import Document, Index, fields from elasticsearch_dsl import analyzer from App.models import Post # elasticsearch index posts = Index('posts') html_strip = analyzer( 'html_strip', tokenizer="standard", filter=["lowercase", "stop", "snowball"], char_filter=["html_strip"] ) @posts.document class PostDocument(Document): ... more index stuff According to the docs I have to manually setup a default client connection where I can also pass the password and username for authentication wich to me seems not to be possible at settings.py at moment.

Django admin page and CSS
I'm very new to django. I just did the very basic step for creating a project which has one application. I started the server using python manage.py runserver which ended up giving me my home page. but when I opened the admin page it was not with proper CSS as it is supposed to be.

STATIC_ROOT = os.path.join(BASE_DIR, 'static') STATIC_URL = '/static/' But this doesn't reflect anything after running python manage.py collectstatic. Do I need something else to done further?

Django IIS Active Directory Single Sign On (SSO)
I have application written in Django, hosted with IIS on my intranet with Active Directory. Following this stackoverflow topic https://stackoverflow.com/a/26987622/4992056 I managed to create basic domain authentication. Unfortunately this solution reqiures login with domain account credentials everytime I rerun browser what is not ideal user experience and brings security issues (browser prompts user to save their domain account credentials). I would like to have true single sign-on feature that means: when user is signing in with his domain account, he/she should also be signed in to the web app without prompting for password. Thanks in advice for your answers. Best regards, Wojtek -
