Django nested transacion.atomic() questions. Is it significant what exception is raised to abort a transaction?
I'm writing code which is basically to upload a spreadsheet. Each row requires the creation of multiple DB objects and relationships. If the data in the row is incapable of being stored, I want to tell the user about the problem, abort the transction representing this row, and continue with the next row. But if there's a more disastrous failure or "too many errors", I want to abort the outer transaction to commit nothing at all to the DB. Is there any particular recommended Python or Django exception class to subclass, to generate exceptions for this purpose? And can I safely catch IntegrityError in the row-processing code so as to issue the best possible error to the user, and then exit the inner transaction by railsing a different exception? I'm thinking Class CannotStoreRow( ValueError): pass, because something in that row of data is an invalid value. Is there any reason something other than ValueError should be used? (Why doesn't Django supply something like AbortTransaction, or does it? ) Overall outline code: try: with transaction.atomic(): process_spreadsheet() except CannotContinueLikeThis: # tell user we have given up and reassure that the DB is unaltered # uncaught exception, DB likewise undamaged? def process_spreadsheet(): # … -
Django ORM: move filter after annotate subquery
This Django ORM statement: Model.objects.all() \ .annotate( ord=Window( expression=RowNumber(), partition_by=F('related_id'), order_by=[F("date_created").desc()] ) ) \ .filter(ord=1) \ .filter(date_created__lte=some_datetime) Leads to the following SQL query: SELECT * FROM ( SELECT id, related_id, values, date_created ROW_NUMBER() OVER ( PARTITION BY related_id ORDER BY date_created DESC ) AS ord FROM model_table WHERE date_created <= 2022-02-24 00:00:00+00:00 ) WHERE ord = 1 As you can see, the date_created__lte filter gets applied on the inner query. Is it possible to control statement location preciser and move the filter outside, like ord? -

Django error path does not exist. Static files sometimes do not load
I have a weird problem with my app in Django. The link for the app is www.mativated.com. The problem is - sometimes the app loads normally, but very often, some static files do not load - that's why it looks like page is bugged. These are the logs.

What is the proper way to pass a JS object as a django field value?
Given the following form: from django import forms class MyForm(forms.Form): my_field = forms.CharField() views.py from django.shortcuts import render from myapp.forms import MyForm def index(request): form = MyForm() if request.method == 'POST': form = MyForm(request.POST) return render(request, 'index.html', {'form': form}) index.html <!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Title</title> </head> <body> <form method="post"> {% csrf_token %} {{ form }} <button type="submit">Submit</button> </form> </body> </html> I don't mean the field to be a character field, it's just for the sake of the example. What would be the proper and safe way to pass a JS object as the field value? This would be one possible way to do it. I'm not sure how safe or proper this is: document.querySelector('#id_my_field').value = JSON.stringify({a: 1, b: 2}) and then parse the resulting string: >>> json.loads(form.cleaned_data['my_field']) {'a': 1, 'b': 2} Yeah, I know I could just create a and b fields and make them numeric or whatever the dtype is but this is not an option in my case because these field values will be set dynamically and how many values are expected cannot be known in advance, so this is the convenient way to pass as many values as needed. -

How to get average by month in Django queryset?
I have been trying to get average values per month for the rainfall.

Should i be using raw SQL here? and Can someone kindly help? i am new to Django. Thanks in advance. -

How to allow users to attach multiple images to a Django post using a ModelForm and formset?
I'm building a Django app that allows users to create posts and attach images to those posts. Each user can create multiple posts, and each post can have multiple images. I'm using a ModelForm to handle the creation of posts, but I'm having trouble figuring out how to handle the creation of the images associated with each post. Here's my current code: models.py class Post(models.Model): title = models.CharField(max_length=200) body = models.TextField() class Image(models.Model): post = models.ForeignKey(Post, on_delete=models.CASCADE) image = models.ImageField(upload_to='post_images/') forms.py class PostForm(forms.ModelForm): class Meta: model = Post fields = ['title', 'body'] views.py def create_post(request): if request.method == 'POST': form = PostForm(request.POST) if form.is_valid(): post = form.save(commit=False) post.author = request.user post.save() return redirect('post_detail', pk=post.pk) else: form = PostForm() return render(request, 'create_post.html', {'form': form}) What's the best way to modify my code to allow users to attach multiple images to their posts when they create them? How can I modify the PostForm to handle this, and how should I modify the create_post view to save the images along with the post? Any help is greatly appreciated! -

integrating fusionauth and django-rest-framework
I am trying to integrate FusionAuth and Django-Rest-Framework (with a React frontend), and am getting very confused. I have some code that kind of works. It uses the "authorization code grant". The React frontend redirects to the FusionAuth login page which once submitted redirects back to the frontend with an authorization_code as a URL Parameter. The frontend passes that code to the Django backend which exchanges it for an access_token. That access_token is used to get some user information from FusionAuth including a unique id with which to create a local Django User (if one doesn't already exist). It then generates a local token and passes that to the frontend to use for authentication in future requests. Here is some pseudo-code: from fusionauth.fusionauth_client import FusionAuthClient client = FusionAuthClient(FA_API_KEY, FA_URL) def authenticate(request): authorization_code = request.data["code"] fa_token_response = client.exchange_o_auth_code_for_access_token() fa_user_response = client.retrieve_user(user_id=fa_token_response["userId"]) user, created = UserModel.objects.get_or_create( fa_id=fa_token_response["userId"], defaults={ "username": fa_user_response["username"], "email": fa_user_response["email"], }, ) token = generate_token(user) # THIS IS PROBABLY WRONG return Response( { "token": token, "user_id": user.id, } status=status.HTTP_200_OK, ) As you can see, I generate my own token (I happen to be using knox, but that's not important).

I get the error "detail": "Method \"GET\" not allowed." when trying to make an action
Not really sure why this is happening. I want to send a leaderboard with some data. I already made it work as part of my view/ but i wanted to implement it in an action. Yet when I do it, I get this error. This is my code in my view file @action (methods="GET", detail=False, serializer_class=LeaderboardSerializer, permission_classes=[AllowAny]) def Leaderboard(self, request): return Response({ "results": str(request.results) },status=status.HTTP_200_OK) Not working :( -
What is best practice for storage of AWS credentials within a django application?
I'm new to using AWS Services and Django together and I'm having trouble finding information around best practices for storing your aws creds for Django to access? I have a basic django application that's connected to an S3 bucket, so I need to be able to use boto to invoke the connection to the bucket. But I'm not sure how to go about storing the aws credentials I would need to pipe into my boto functions to use any of the services. I have read in a few places of people putting their aws credentials into the settings.py file within their django project, but this doesn't really feel secure to me. I also looked into AWS Secrets Manager, but it looks to me as though it's more suited for keys related to other services. Could anyone perhaps explain what my other options are, or why storing them in settings.py is perhaps a safe option? Really not certain on the best way to go about this one. -
