CSRF Protection for django session-based auth for Hasura + auth webhook
I have a react app for the frontend, a hasura instance for the graphql engine connected to my database and a django app for their easy session-based authentication, ORM and migrations. Before I introduced the Hasura instance my authentication worked like a charm. I would get the CSRF Token and HTTP-Only cookie from django, in my frontend and when sending POST requests would send the token in the headers along with the cookie that is sent automatically. For Hasura I have to use a webhook to authenticate the graphql requests and I wanted to do this with my already in-place django sessions. Using the apollo client i setup a middleware to get csrf token and cookie from my django app and send it along with every request, where Hasura would then (hopefully) forward them to the django webhook. But now my problem is: Django only does CSRF checks for POST requests, and if I configure Hasura to send a POST request to my webhook it puts all the headers from my client request in the body as JSON, and django CSRF middleware doesn't pass the checks. Is there a way to force django to do CSRF checks for a specific … -

How can I reuse a Django view with a post method for my API

Django filtering with select_related using Custom QuerySet, works in shell, fails in views

This (seems to) makes sense, because I am calling select_related on a QuerySet object - however, the error is a bit misleading, because it does identify and report the correct class (Foo) but then says that it has no author field. It would make sense if the error message said something like ItemQuerySet has no 'author' field. In order to test that my reasoning was correct, I decided to test my hypothesis in the shell: console output from foo.models import Foo foo = Foo.objects.get(id=1) foo.author … -

Why pagination provided by django rest framework is not consistent?
I am currently using Django-Rest framework to implement the API endpoints. I am following the documentation to implement the pagination, my pagination class is, class Pagination(PageNumberPagination): page_size = 10 page_size_query_param = 'page' I am using this class as follows:- class QuestionList(generics.ListAPIView): queryset = Question.objects.all().prefetch_related('tags').order_by('id') serializer_class = QuestionSerializer pagination_class = Pagination For the first page, i am getting objects from id 1 to 10 which is expected. But from second page onwards, i am only getting 2 objects per page(id 3 and 4 for second page) and i cannot find any reason behind this strange behaviour. What should i do to make the pagination consistent. -

Accessing values in a JSON array and then assigning it to a textfield
My question is very simple. By using the DjangoJSONEncoder, I am able to send a JSON array of Model instances with the fields, product_number(pk) and amount as context to the HTML file. I then access the JSON array obj using some javascript code. The JS code: {{ data|json_script:"hello-data" }} <script type="text/javascript"> const data = JSON.parse(document.getElementById('hello-data').textContent); document.getElementById('id_line_one').onchange = function(event){ alert(data); document.getElementById('id_line_one_unit_price').value = data[event.target.value].fields.amount }; </script> The array is: [[1, 56000], [2, 55000]] I think it's a string and not an array? I have a dropdown box and when the user selects a title from the dropdown menu, It returns the primary key of that title, and then using that, I want to retrieve the amount of that product from the JSON array and then set the value of a text field with that amount. views.py: def add_invoice(request): form = InvoiceForm(request.POST or None) total_invoices = Invoice.objects.count() queryset = Invoice.objects.order_by('-invoice_date')[:6] dataa = Inventory.objects.values_list('product_number','amount') data = json.dumps(list(dataa), cls=DjangoJSONEncoder) if form.is_valid(): form.save() messages.success(request, 'Successfully Saved') return redirect('/invoice/list_invoice') context = { "form": form, "title": "New Invoice", "total_invoices": total_invoices, "queryset": queryset, "data": data, } return render(request, "entry.html", context) models.py: from django.db import models class Inventory(models.Model): product_number = models.IntegerField(primary_key=True) product = models.TextField(max_length=3000, default='', blank=True, null=True) title = models.CharField('Title', … -

AttributeError at /invoice/add_invoice/ 'int' object has no attribute '_meta' while using in_bulk
I want to convert the model instances into a JSON object and then pass it to the HTML file. However, I get an AttributeError at this line: data = serializers.serialize("json", Inventory.objects.in_bulk()) The full views.py: def add_invoice(request): form = InvoiceForm(request.POST or None) data = serializers.serialize("json", Inventory.objects.in_bulk()) total_invoices = Invoice.objects.count() queryset = Invoice.objects.order_by('-invoice_date')[:6] if form.is_valid(): form.save() messages.success(request, 'Successfully Saved') return redirect('/invoice/list_invoice') context = { "form": form, "title": "New Invoice", "total_invoices": total_invoices, "queryset": queryset, "data": data, } return render(request, "entry.html", context) The Javascript code: {{ data|json_script:"hello-data" }} <script type="text/javascript"> const data = JSON.parse(document.getElementById('hello-data').textContent); document.getElementById('id_line_one').onchange = function(event){ document.getElementById('id_line_one_unit_price').value = data[event.target.value].fields.amount; }; </script> models.py: class Inventory(models.Model): product_number = models.IntegerField(primary_key=True) product = models.TextField(max_length=3000, default='', blank=True, null=True) title = models.CharField('Title', max_length=120, default='', blank=True, unique=True) amount = models.IntegerField('Unit Price', default=0, blank=True, null=True) def __str__(self): return self.title How can I pass that JSON object and assign the amount value to the text field according to the object selected in the dropdown?

Django nginx staticfiles 404
I am trying to get my head around nginx serving Dockerized Django static files behind a https proxy. I was trying to mostly follow this tutorial: https://testdriven.io/blog/django-lets-encrypt/ This was all working on my local machine so I moved to a remote server running at a real domain behind an https reverse-proxy. I have a docker-compose.yml like this: backend: ... volumes: - ./backend/:/code/ - static_volume:/code/staticfiles - media_volume:/code/mediafiles ... nginx-proxy: ... volumes: - static_volume:/code/staticfiles - media_volume:/code/mediafiles ... depends_on: - backend I have a default file in vhost.d directory with the following directives: location /static/ { alias /code/staticfiles/; add_header Access-Control-Allow-Origin *; } location /media/ { alias /code/mediafiles/; add_header Access-Control-Allow-Origin *; } my nginx docker files is the following: FROM jwilder/nginx-proxy:0.9 COPY vhost.d/default /etc/nginx/vhost.d/default COPY custom.conf /etc/nginx/conf.d/custom.conf my Django settings.py: STATIC_URL = '/static/' STATIC_ROOT = BASE_DIR / 'staticfiles' I am collecting the files at backend boot and if I exec to either the backend or nginx-proxy services I can find my files at the correct location: /code/staticfiles/... # all the files are here in the right place... So I "assume" the volumes are correct. /vhosts.d/default is also present and at the correct location when i log into the nginx service. The HTTPS reverse-proxy works … -
Using django and react together
I'm making an SSR website using Django, Gunicorn, and Nginx. As I'm familiar with react and I'd like to use some of its libraries like redux, tailwind with daisyui, etc... it would be great if I could use React for the frontend and Django for the backend. I am aware I can use Django just as a rest framework and then run react separately as a CSR, SSG app, or even ssr using something like nextjs but my goal is to keep most of the react functionality, share the codebase, use Django to render the react pages essentially as a replacement for react-router, and optimize SEO. I was wondering what the best way to integrate them is? I know generally, it's common to separate react and Django but I'd like to use Django as the router/renderer for the react app as I believe it would be more performant to use one server for both the API and the website. I also plan on using django-hosts to render the react templates in two Django apps with different hostnames. Note: I don't need to be able to use the normal django templating
