Failing to authenticate my React frontend with backend using google-auth-login: Failing likely due to polyfills missing in react-scripts 5
I deployed both my backend (Django) and frontend (React create-app) services to Google Cloud Run. As long as my Django service doesn't require authentication, everything works great. I've tried following this doc on authenticating service-to-service but without any success. As soon as I import google-auth-login, my react app errors out with a series of dependency missing (browserify, url, crypto, etc). I've read from other questions that this is due to react-scripts 5 missing polyfills. I've tried to download them and add the fallbacks to my webpack.config.js as directed by the error messages but even when I add them all and resolve this issue I run into a series of warnings/errors , failing to parse different modules like: 'node_modules/https-proxy-agent/src/agent.ts', 'node_modules/google-auth-library/build/src/auth/oauth2client.js.map', 'node_modules/google-auth-library/build/src/auth/iam.js.map' etc. What am I doing wrong? Are there alternatives to using google-auth-login to authenticate my frontend service? Should I just deploy those outside of Google Cloud Run? -

Using MSAL Python/Django, how do I get Authenticated event?
I have a working Django app that uses the MSAL library ms-identity-python-utilities@main. I can successfully sign in to Azure AD. I need to however load the local user object from my database on successful sign in, like I used to do in my old /login URL endpoint, to call auth_login(request, user). This should happen after the OAuth2 flow succeeded. Intent is to use OAuth2 as SSO. How do I intercept this event? I.e. after successful OAuth2 authentication, call a method that can call auth_login(request, user) and set the user object into the session for future use? I could not find any references in the samples / forums. @ms_identity_web.login_required works to ensure authentication for views, but I want a decorator or class I can extend to intercept signed on event. -

Set Empty Fields After Submission Using FormView
Currently I have a django project which includes a RegisterForm and a RegisterView these appear as the following: class RegisterView(FormView): ... def form_valid(self, form): ... return HttpResponseRedirect(...) Similarly, class RegisterForm(forms.Form): ... def clean(self): ... return data At the submission page of the RegisterForm I've come to realize that it doesn't run form_valid() until not a single error appears in clean(). My only issue with this is that, if any errors occur I want to be able to set certain fields to empty on submission. How can I do this? For more details, I want to keep all the values on the page but remove some of them, the code already does this perfectly but it keeps everything until its validated and I can't seem to remove some of them. I tried passing through self.request to my RegisterForm to see if I could update the self.request.session[...] = '' but this doesn't seem to work. I also tried updating the initial value inside clean() by doing self.initial[...] = '' but this doesn't seem to be working either. I'm kind of stuck and worried I might have to change the design of my program (which I don't want to have to do because … -
How to render pdfs separately based on a OneToMany model using DRF?
I have a OneToMany model where a Contest can have many Documents. Each document has a PDF file, and I need to render each PDF file separately for a given contest. To achieve this, I created a Document model with a ForeignKey to Contest and a FileField to upload the PDF file. I also created a DocumentViewSet with a custom action to upload a PDF file to a document. Finally, I created the necessary URLs to handle the requests. I wrote a test case to upload a PDF file, but it gives me the following error: {'detail': ErrorDetail(string='Not found.', code='not_found')} Here is the code for my attempt: models.py class Document(models.Model): contest = models.ForeignKey(Contest, on_delete=models.CASCADE, related_name='documents') pdf = models.FileField(null=True, upload_to=contest_pdf_file_path) uploaded_at = models.DateTimeField(auto_now_add=True) document_slug = models.SlugField(max_length=255, blank=True) def __str__(self): return f"Document for {self.contest.title}" views.py class DocumentViewSet(viewsets.ModelViewSet): serializer_class = serializers.DocumentSerializer queryset = Document.objects.all() authentication_classes = [TokenAuthentication] permission_classes = [IsAuthenticated] lookup_field = 'document_slug' def get_queryset(self): return self.queryset.order_by('-id') def perform_create(self, serializer): serializer.save() def get_serializer_class(self): if self.action == 'upload_pdf': return serializers.DocumentSerializer return self.serializer_class @action(methods=['POST'], detail=True, url_path='contests/(?P<contest_slug>[-a-zA-Z0-9_]+)/upload_pdf') def upload_pdf(self, request, contest_slug=None, document_slug=None): document = self.get_object() serializer = self.get_serializer(document, data=request.data) if serializer.is_valid(): serializer.save() return Response(serializer.data, status=status.HTTP_200_OK) return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST) urls.py router = DefaultRouter() router.register('contests', views.ContestViewSet) router.register('tags', views.TagViewSet) … -

How to make variables sort and not repeating itself in Python-Django HTML page

Deploying a Django-React app to Heroku: how to run npm and webpack
I'm currently trying to deploy a Django-React application to heroku using their build manifest approach. I have been roughly following this tutorial for configuring the relationship between React and Django.

I can build and deploy to Heroku just fine, but the heroku app cannot find my "main.js" static file, which is the entry point to my react application. heroku.yml file looks as follows: build: docker: web: dockerfile: Dockerfile.heroku release: image: web command: - cd front_end && npm run dev run: web: gunicorn focal_point.wsgi:application --bind 0.0.0.0:$PORT where Dockerfile.heroku looks as follows: FROM python:3.9 AS back_end ENV NODE_VERSION=16.13.0 RUN apt install -y curl RUN curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.0/install.sh | bash ENV NVM_DIR=/root/.nvm RUN .

How to hook up DRF ModelViewset to the app's root
I have a small django app with a single ViewSet that extends DRF's ModelViewSet. I've tried attaching it to the app's root url like so urlpatterns = [ path(r"", NotificationViewSet.as_view(), name="company"), ] But this is causing an error: TypeError: The actions argument must be provided when calling .as_view() on a ViewSet. For example .as_view({'get': 'list'}) The error is helpful enough to show how to map the get method and github copilot suggests: urlpatterns = [ path( r"", NotificationViewSet.as_view( { "get": "list", "post": "create", "patch": "partial_update", "delete": "destroy", } ), name="company", ), ] But I'm not sure this is correct. And this doesn't appear to handle retrieve which would require a URL parameter. I am surprised I have to be so explicit. Surely there is an easier way. -
