OpenCV opens camera at the first load, but if I refresh the page, it doesn't bring camera (can't open camera by index)
I have this Django project for Video-Streaming. So everything works perfectly fine on my system (MacOS).

"ValueError: not enough image data" from Pillow when saving to a Django ImageField
I have a Django model like: class Website(models.Model): favicon = models.ImageField( null=False, blank=True, default="", width_field="favicon_width", height_field="favicon_height", ) favicon_width = models.PositiveSmallIntegerField(null=True, blank=True) favicon_height = models.PositiveSmallIntegerField(null=True, blank=True) I'm fetching a .ico file and saving it to the favicon field as a .png like this: import io import requests from django.core import files from .models import Website website = Website.objects.get(pk=1) response = requests.get("https://www.blogger.com/favicon.ico", stream=True) image_data = io.BytesIO(response.content) website.favicon.save("favicon.png", files.File(image_data)) Behind the scenes, Pillow successfully converts the ICO file to a PNG, and saves the file.

Why am I getting a Bad Gateway Error sending bulk emails with Django
I have a need to send bulk emails, as much as 60 at a time, using an action in the Admin module. I do this by selecting certain cases and then running an admin action. Sometimes when I do this, not all 60 emails send. Sometimes they seem to go in batches of 20/30 and there could be a delay of a few hours between batches. This time I got an incomplete batch being sent and a 'Bad Gateway' error, with 8 emails not being sent. Those that what sent were sent twice. I can't see anything wrong with my code that would cause this. Any ideas would be greatly appreciated. I have the following Admin Action in my admin.py file: emailset=queryset.all().order_by('customer') for q in emailset: customer=q.customer email_to = q.customer.email html_content = render_to_string("accounts/email_template_staff_registration.html", {'q':q}) text_content = strip_tags(html_content) email = EmailMultiAlternatives( #subject "Staff Registration Email", #content text_content, #from settings.EMAIL_HOST_USER, # rec list [email_to], ['INSERT EMAIL ADDRESS FOR CC'] ) email.attach_alternative(html_content, "text/html") email.send() updated=len(queryset) self.message_user(request, ngettext( '%d Staff Registration Email was successfully sent.', '%d Staff Registration Emails were successfully sent.', updated, ) % updated, messages.SUCCESS) send_staff_reg_email.short_description="Send staff registration email" ``` -

What's the best way to implement JWT authentication with multiple clients?
We currently use Djoser (with simplejwt), which has served us well. The only OAuth clients we had so far have been frontend apps. However, we now have to add access to some external services. There is no appetite to have separate gatekeeper proxy. This will need longer token life, etc and the simple_jwt is no longer the best solution. DRF website has a long list of third party libraries, which is great to have the choice, but makes the choice harder. Which of these packages, or another one that's not listed there, is a fairly easy replacement for Djoser? Ideally, it would be something which doesn't require us to write new views, etc for everything. -

Loading of GDAL library impossible after an upgrade

understanding of urlpatterns in urls.py of Django App
Problem: When we try to add the data to the database. So, the request will always come to this URL starting with the project-level directory, todo_main. So here, we will create a pattern. path('todo/', include('todo.urls')), This path will forward the request to todo. URLs. from django.urls import path from .import views urlpatterns =[ path('addTask/', views.addTask, name='addTask'), ] So whenever we send a request to add a task, then the corresponding views.addTask should run, which will be a task. Questions: I try to understand my best what is the meaning or purpose of addTask. Can we write another word instead of it? -
Django path converter not converting value in path
I have an app that should be able to take a field's value in lower and uppercase. The url below should work http://localhost:8000/app/family=Araceae/ but fail if value is araceae. I followed the official documentation but it's not working. path('app/family=<str:family>/', views.SpeciesDetail_family.as_view(), name='family') I made a converter to convert the value to lower case if it's in uppercase but is returning 404 saying URL does not match the patterns below admin/ app/family=<value:family>/ [name='family'] app/family=<value:family><drf_format_suffix:format> [name='family'] urls.py from django.urls import path, register_converter from rest_framework.urlpatterns import format_suffix_patterns from app import converters, views register_converter(converters.convert_value_to_lowercase, 'value') urlpatterns = [path('app/family=<value:family>/', views.SpeciesDetail_family.as_view(), name='family')] urlpatterns = format_suffix_patterns(urlpatterns) converters.py class convert_value_to_lowercase: regex = '[A-Z]' def to_python(self, value): value = value.lower() return value def to_url(self, value): return value -
Dockerise Django with proxy server NGINX
I have dockerised a django application. And now I try to deploy the app to a live server. So I am using the NGINX reversed proxy server. I have a folder name called proxy within a dockerfile: FROM nginxinc/nginx-unprivileged:1-alpine COPY ./default.conf.tpl /etc/nginx/default.conf.tpl COPY ./uwsgi_params /etc/nginx/uwsgi_params COPY ./run.sh /run.sh ENV LISTEN_PORT=8000 ENV APP_HOST=app ENV APP_PORT=9000 USER root RUN mkdir -p /vol/static && \ chmod 755 /vol/static && \ touch /etc/nginx/conf.d/default.conf && \ chown nginx:nginx /etc/nginx/conf.d/default.conf && \ chmod +x /run.sh VOLUME /vol/static USER nginx CMD ["/run.sh"] and a default.conf.tpl file: server { listen ${LISTEN_PORT}; location /static { alias /vol/static; } location / { uwsgi_pass ${APP_HOST}:${APP_PORT}; include /etc/nginx/uwsgi_params; client_max_body_size 10M; } } And a run.sh script: #!/bin/sh set -e envsubst < /etc/nginx/default.conf.tpl > /etc/nginx/conf.d/default.conf nginx -g 'daemon off;' and docker-compose-deploy.yml looks: version: "3.9" services: app: build: context: . dockerfile: Dockerfile.prod restart: always volumes: - static-data:/vol/web environment: - DJANGO_ALLOWED_HOSTS={DJANGO_ALLOWED_HOSTS} env_file: - ./.env.prod proxy: build: context: ./proxy restart: always depends_on: - app ports: - 8000:8000 volumes: - static-data:/vol/static volumes: static-data: part of my settings.py file looks like: import os import dotenv dotenv.read_dotenv() from pathlib import Path from os import environ import dotenv # Build paths inside the project like this: BASE_DIR / 'subdir'.
