Django race conditions between create() and get()
Since our last release a range of what seems can only DB race conditions have been happening.We use python 3.10, django-rq, Django 4 and Postgres. In one case: x = Model.objects.create() job.delay(x=x) In the job we call Model.objects.get(id=x.id) and it returns nothing. This is happening roughly 1 in 5 times from logs In another case we create the object, add it to a list then act on the list and again it works most of the time but we are getting one off 'matching query does not exist.' errors. I am completely stumped as to what I should do, I cant find many similar issues and can't recreate the issues in my test environment. My best assumption is too many writes to the DB so the transactions aren't being committed by the time the code tries to get the objects again. Any help/advice would be amazing Have gone through the code step by step to ensure the logic is sound Have tried recreating a 'busy' DB but have had no success there Have tried broken data etc but it all gets caught and our logs don't suggest anything like this either -
Enable adding a model field choices to Django admin dashboard and also be able to add or delete the choices
The normal way of interacting with a django model is by using admin.site.register(my_model) in admin.py file. If you want to enforce model's field validation you use the choices field option like this in models.py file. from django.db import models MY_CHOICES=[ ('A','choice 1'), ('B','choice 2'), ('C','choice 3'), .... ] class MY_MODEL(models.Model): ....Some other fields/columns.... options=models.CharField(max_length=2,choices=MY_CHOICES) How would I go about displaying the choices in the admin dashboard and also be able to add new types of choices? Also, is it possible to enforce validation by importing values from the database as field options? I tried having another model that will be a table containing the value and descriptions columns. class MY_CHOICES_MODEL(models.Model): value=models.CharField(max_length=2,..) descriptions=models.TextFeild(blank=False) Trying to pass this around to another models field options is the challenge -

Pytorch RuntimeError: mat1 & mat2 shapes cannot be multiplied(1x2 and 10000x100)

DRF formdata with file and nested array of objects not taking nested array of objects
Unable to send nested objects when using formdata. Since I have large number of files using base64 is not a solution. current solution was to use JSON.stringify from client side for product_timings and send it as a single field, But I would like to know if normal modal field with file upload is possible with DRF. Here is my APIView class ProductCreateApi(APIView): permission_classes = [permissions.DjangoModelPermissions] queryset = Product.objects.all().order_by("-created_at") parser_class = [MultiPartParser, FormParser, JSONParser, FileUploadParser] class ProductCreateSerializer(serializers.ModelSerializer): class ProductCreateProductTimingSerializer(serializers.ModelSerializer): class Meta: model = ProductTiming fields = ['start_time', 'end_time'] product_timings = ProductCreateProductTimingSerializer(write_only=True, many=True) product_images = serializers.ListField( child=serializers.ImageField(allow_empty_file=False, use_url=False), write_only=True ) class Meta: model = Product fields = '__all__' In post man I tired product_timings[0][start_time]: 09:30:00 product_timings[0][start_time]: 09:30:00 Still it is throwing validation error messages like { "product_timings": [ { "start_time": [ "This field is required." ], "end_time": [ "This field is required." ] } ] } Please note neither base64 image field for product_images nor single JSON field for product_timings is not the solution I'm looking for. -
Something similar to Counter in a Django table
I have a table in sqlite3 with a column that tells me the winners of a game: (computer = 1, human = 2, tie = 0) The model (I'm working on django) is something like this, at least the necessary part: class GameWinners(models.Model): CHOICES = [(0, 'Draw'), (1, 'Computer'), (2, 'Human')] game_winner = models.IntegerField(choices=CHOICES) I would like to obtain a dictionary that counts me the times that each one has won or the ties. something similar to Counter from collections: games = {0: 27, 1: 125, 2: 170} I know that I could do it this way: tie = GameWinners.objects.filter(game_winner=0).count() computer = GameWinners.objects.filter(game_winner=1).count() human = GameWinners.objects.filter(game_winner=2).count() games = {0: tie, 1: computer, 2: human} But I guess there must be a better way to do it. -
JavaScript: Problem accessing 'change' event for a file input
Aim I have two inputs: (1) a 'file-input', and (2) a 'text-input' I want to listen for a 'change' in 'file-input' (i.e. successful choice of file), and upon such a change set the 'text-input' value to the name of the file. Problem The 'change' event is not triggering when I use addEventListener When I use the input's 'onchange' attribute, it does trigger, but I still don't get access to files Context: This is for a Django project, with Bootstrap 5 on the frontend (NO JQuery). I am using Django Crispy Forms where possible, though I have removed them from this file (to see whether that was what was causing the problem - alas, it wasn't). Attempted Solutions I know this should be easy. I have seen lots of similar posts about this, and I set up a 'dummy' HTML script to ensure I'm not going mad. This is posted below and it works perfectly. <!DOCTYPE html> <html lang="en"> <head> <title>Document</title> </head> <body> <input type="file" name="file" id="file-input" accept=".mp3,.mp4,.mpeg,.mpga,.m4a,.wav,.webm"> <input type="text" name="text" id="text-input"> <script> const fileInput = document.getElementById("file-input"); const textInput = document.getElementById("text-input"); console.log(fileInput); console.log(textInput); fileInput.addEventListener('change', () => { console.log('change registered'); if (fileInput.files.length > 0) { console.log(fileInput.files); console.log(fileInput.files[0].name); textInput.value = fileInput.files[0].name; } }); … -

(Python/Django) Can I use Python's Django framework w/o using templates?
I am learning how to use the Django framework, and as I am learning about Django's template system, I was wondering, if it would be possible for me to use Django without using templates to render the necessary html documents from views? As an alternative to Django's template system, I would prefer to use JavaScript in order to make the necessary data queries from the sites database(s). This might seem counter productive, but in my opinion, I would prefer to learn the traditional front-end web stack(HTML, CSS, JS), and solidify my skills this way before going down the journey of template systems. At this point, I would be using Django only as a back-end until I was ready to incorporate templates into my dev process. Thank you in advance! This my first post on SO, take it easy! I have tried to use Django's template system, but It's a little comprehensive to learn on top of HTML and CSS at the same time. -
