How to deploy label studio on Azure VM?
I want to deploy label studio annotation package to my azure VM. It is based on Django. I know how to deploy Django apps. But I was curious to know if there is any possible way to deploy it more efficiently. I am hesitant to try docker right now because I have one more Django app deployed on the same VM using Apache, and I fear using docker might break it. -

Django Admin one field required related on other field

Django App to read QR code URL and display image on website
I am creating a django that displays different images on a website when their respective QR codes are scanned. Its my first time working with Django and I am unsure how to update the index page to display the image when the QR code is scanned. I would like to add a URL route that should make the image visible when the QR code is scanned but I am unsure how to carry out that logic in django. views.py def index(request: HttpRequest) -> HttpResponse: return render(request, "index.html") # template = loader.get_template('index.html') # return HttpResponse(template.render({}, request)) urls.py from django.contrib import admin from django.urls import path from . import views urlpatterns = [ # path('admin/', admin.site.urls), path("", views.index, name="index") ] index.html {%extends 'base.html' %} {% load static %} {% block title %} Home {% endblock %} {% block content %} <div class="grid-container"> <figure class="gallery__item gallery__item--1"> <img id="image1" src="{% static 'theme/assets/img/Freesample.svg' %}" class="gallery__img" alt="Image 1"> </figure> </div> {% endblock %} scripts.js function setImageVisible(id, visible){ var img = document.getElementById(id); img.style.visibility = (visible ?

append the char field in django models
I have a simple choice field in my model which saves present or absent of a student for his/her attendance. However, what I felt is, it will create different object for just a status of his/her attendance. Is there any way to just append present or abset to the same field to save the resource of the database?? My models look like this: class OnlineClass(models.Model): teacher = models.ForeignKey(Teacher,on_delete=models.CASCADE) course = models.ForeignKey(Subject,on_delete=models.CASCADE) faculty = models.CharField(max_lenthg=255) students_in_class = models.ManyToManyField(Student) STATUS = ( ('present','present'), ('absent','absent'), ) class Attendance(TimeStampAbstractModel): classes = models.ForeignKey(OnlineClass) student = models.ForeignKey(Student) status = models.CharField(choices=STATUS, max_length=10, blank=True) By using this model, there will be different object of attendance for each student of each course which will be consuming huge resources. Instead what I want is just append present or absent for each day of attendance to the status field just like django-taggit. So that when I call get api, I will be getting like a list of attendances.Is it possible?? -

How can I reduce the deep learning model inference inside Django server
I have a Pytorch vision model which takes <4 seconds for performing inference on a image on CPU when calling as a standalone python program or calling from Django as a subprocess, but when the same inference method is called from Django server inside view.py methods, the time for performing inference is >50 seconds.

django-rest-framework-social-oauth2: error 400 - redirect_uri_mismatch
I've been trying to add google login to my django app following this tutorial: https://github.com/RealmTeam/django-rest-framework-social-oauth2 By following exactly the instructions, everything works fine in local. However, when I try to replicate the same on the server, I get the following error on the redirect page of the login: Error 400: redirect_uri_mismatch redirect_uri: http://localhost:8000/auth/complete/google-oauth2/ What is strange to me is, in my google developer console, I have set up the correct redirect url in my app, as follows: https://mydjangoapp.com/auth/complete/google-oauth2/ And I have also put 'mydjangoapp.com' under 'Authorised JavaScript origins'. So my question is, why google keeps telling me that the redirect url is http://localhost:8000/auth/complete/google-oauth2/ which is not the one I have set up in the console? Perhaps there is something obvious that I'm missing here. Thank you! -

How to change Django admin url for rewrite urls
I have Django project, which is deployed to kubernetes, where I need to rewrite the admin url to different endpoint.
