Why are my Docker containers not taking advantage of added vCPUs?
We have a Docker app with three containers (Django, PostgreSQL, and nginx) that's been running slowly. I am trying to speed up the app by brute force - quadrupling RAM and CPU on the hosting virtual machine. However, I'm not seeing any real benefit from the increase in vCPUs - the overall CPU usage seems to have dropped proportionally, so my peaks at nearly 100% on the 2-vCPU VM have gone down to about 25% on the new 8-vCPU VM. Naturally, the app is not running faster. I'm using Desktop 4.15.9 (93002) on a cloud-hosted virtual machine with 32 GB RAM and 8 vCPUs running Windows Server 2022 Standard 21H2. What might I be doing wrong or missing? As an experiment, I used docker update to try and set how many and which CPUs were being used by each container: docker update --cpus=2 --cpuset=4-5 django docker update --cpus=2 --cpuset=6-7 pg I expected that more CPU usage would be shown for individual logical CPUs in Task Manager and Resource Monitor. However, I did not see any difference in the pattern of usage when I changed cpusets and repeated my slow operation, so I'm ... confused. FWIW, docker stats shows CPU% going … -

Django - Allow duplicate user's emails in the grand User model, but unique in its extended models?
Django - Allow duplicate user's emails in the grand User model, but unique in its extended models? I'm working on a project in Django which have a User model extend from AbstractBaseUser; and 2 models extend from User (Customer and Technician). Its working all fine when creating a user or customer or technician. However, whenever I register a new user as either customer or technician (/api/customer/register/ or /api/customer/register/) with the same email (because I define email as username USERNAME_FIELD), it returned me with "This email is already exists." Sure, I understand this since I define the UNIQUE constraint on username and email field in the User model. I want customer to be unique in its own model but not in User model, same for technician. Just like when you sign up for Uber or DoorDash, either you want to be a customer or you want to be a driver or you could be both. AND you could use the same email address to sign up for both. BUT, you cannot use the same email address to sign up again, if you are already signed up with that email as a customer or a driver I have tried to tweak around … -

Updating urlpatterns for django-smart-selects
I am attempting my first django project by building on top of the polls example from the django documentation. I would like to add linked/cascading dropdowns to a form and found my way to django-smart-selects. I read the documentation but wasn't sure how integrate the suggested updates to project's urls.py urlpatterns from the documentation into what I have currently. The smart select urls mentioned in the linked documentation urlpatterns = patterns('', url(r'^admin/', include(admin.site.urls)), url(r'^chaining/', include('smart_selects.urls')), ) The current value of urlpatterns in my project's ursl.py file. urlpatterns = [ path('', include('TimeTracking.urls')), path('admin/', admin.site.urls), path('data-browser/', include('data_browser.urls')), ] Obviously adding those entries to my urlpatterns = [] wouldn't work but I attemtped it anyway...

Django Admin reverse inline many-to-many extremely slow to load
I have three models Organisation, Event and EventReport. Event and EventReport have a many to many relationship. An Event is only ever associated with a single Organisation. An Event may have many EventReports and a EventReport may be related to multiple Events. class Organisation(models.Model): ... name = models.TextField() url = models.URLField() ... class Event(models.Model): ... organisation = models.ForeignKey(Organisation, on_delete=models.CASCADE, related_name = "events") event_reports = models.ManyToManyField(EventReport, blank=True) ... class EventReport(models.Model): date = models.DateField() summary = models.TextField() My objective is to see all of the Events that a particular EventReport is linked to. This is a reverse Many-to-Many relationship, so I am using a "through" model. I've configured admin.py as follows: class EventInLine(admin.TabularInline): model = Event.event_reports.through class EventReportAdmin(admin.ModelAdmin): search_fields=['date','summary'] inlines = [ EventInLine, ] When loading an EventReport in Admin.. it works but takes an extremely long amount of time to load. The EventReport page does list multiple Events under a section called: "EVENT-EVENTREPORT RELATIONSHIPS" Each associated Event is represented in a single dropdown as a Event object e.g. event_event_reports object (10487) with the STR representation of each object in the dropdown. I believe the large amount of time is due to populating the dropdown box with every Event in the database … -
Filter the exact match from the django query set
I have gearbox_model values like this in the queryset in Django gearbox_model = 'XLG , 'SG' I have values arrays and I want to filter these values from the query set values = [ 'LG', SG'] So , I annotate the query set to create the gearbox_model_array queryset = queryset.annotate(gearbox_model_array=SplitComma("gearbox_model")) the gearbox_model_array becomes like this gearbox_model_array = [ 'XLG' , 'SG' ] Then I do filtering for value in values: queryset = queryset.filter(gearbox_model_contains=value) The issue is __contains returning the substring matches as well . For example the record gearbox_model_array = 'XLG , SG' returns as the substring 'LG' exist in it.

Cpanel deployment of Django project getting 404 Not Found Error when entering any path besides just the domain
For the sake of the question, the domain of my site is domainname.com Typing in the domain into the web gets a functional page with loaded html and css. However, when I click on a button, for example, "Register", though the path changes to the correct corresponding path seen in urls.py on my code, instead of generating the corresponding view, I get a 404 notfound error. Here is what my urls.py looks like: urlpatterns = [ path("", views.home, name='home'), path("register/", views.register, name='register'), path("adgen/", views.IndexView.as_view(), name='index'), path('ad/create/', views.ad_create, name='ad-create'), path('ad/<int:pk>/', views.ad_detail, name='ad-detail'), ] I have also attached what the homepage looks like which is able to generate properly: When I enter just the domain- www.domainname.com, the page generates views.home properly However, when I enter anything past just the domain, such as www.domainname.com/register/, the page gives a 404 notfound error. On views.home, I can click a button called "Register" which brings me to the path www.domainname.com/register/ but gives a 404 notfounderror. I can edit urls.py (replacing "" with "hello/" in the first path), looking like the following: urlpatterns = [ path("hello/", views.home, name='home'), path("register/", views.register, name='register'), path("adgen/", views.IndexView.as_view(), name='index'), path('ad/create/', views.ad_create, name='ad-create'), path('ad/<int:pk>/', views.ad_detail, name='ad-detail'), ] and the path www.domainname.com/hello/ gets a … -

Here is my code: def stream(self,request: HttpRequest,user,camera_index): try: url = self.config["cameras"][int(camera_index)]["url"] except IndexError or TypeError: return HttpResponseNotFound() response = StreamingHttpResponse(self.__stream(url),content_type="multipart/x-mixed-replace;boundary=frame") return response def __stream(self,url): video_cap = cv2.VideoCapture(url) while True: _, frame = cv2.imencode('.jpg', video_cap.read()[1],[int(cv2.IMWRITE_JPEG_QUALITY), 100]) yield(b'--frame\r\n' b'Content-Type: image/jpeg\r\n\r\n' + frame.tobytes() + b'\r\n\r\n') First, I want to know whether the __stream function is ended if user close the page. I did some tests about it but I am not sure. Second, can I add a callback to __stream function that will be called when streaming is closed? -
Django channels-redis WS
I have a problem with Redis WebSocket connection. I am using a server that prefers a unixsocket configuration. REDIS CONF FOR MY SERVER My files and sample template look like this: settings.py ASGI_APPLICATION = 'public_python.asgi.application' CHANNEL_LAYERS = { "default": { "BACKEND": "channels_redis.core.RedisChannelLayer", "CONFIG": { "hosts": [(("unix:///home/Temeria/domains/temeria.pl/redis.sock", 8560), {"password": "my_pass"})], }, }, } asgi.py import os from django.core.asgi import get_asgi_application from channels.auth import AuthMiddlewareStack from channels.routing import ProtocolTypeRouter, URLRouter import TableSG.urls # importuj swoje urlpatterns dla WebSocket z urls.py os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'public_python.settings') application = ProtocolTypeRouter({ "http": get_asgi_application(), "websocket": AuthMiddlewareStack( URLRouter( TableSG.urls.websocket_urlpatterns ) ), }) views.py def items_view(request): return render(request, 'TableSG/item.html') class ItemConsumer(AsyncWebsocketConsumer): async def connect(self): await self.accept() items = await self.get_items() await self.send(text_data=json.dumps(items)) @database_sync_to_async def get_items(self): items = SklepModel.objects.all().values() return list(items) urls.py from django.urls import path, include from . import views from django.conf import settings from django.conf.urls.static import static from django.contrib.auth import views as auth_views app_name = 'TableSG' urlpatterns = [ # other urls path('items/', views.items_view, name='items'), ] + static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT) websocket_urlpatterns = [ path('ws/items/', views.ItemConsumer.as_asgi()), ] template item.html {% extends "BaseSG/base.html" %} {% load static %} {% load crispy_forms_tags %} {% block content %} <ul id="items"> </ul> <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.6.0/jquery.min.js"></script> <script> var socket = new WebSocket('wss://' + window.location.host + '/ws/items/'); socket.onmessage = … -
Manually decorating function with extend_schema results in RecursionError
I have a HistoricalModelViewSet class which is used in all other view sets (class StuffViewSet(HistoricalModelViewSet)), it adds couple of /history endpoints (DRF thing, https://www.django-rest-framework.org/api-guide/viewsets/#marking-extra-actions-for-routing). Then I'm using drf-spectacular to generate a /swagger view, and there is a different structure to the /history endpoint than the rest of the view set. So I dynamically decorate the function with extend_schema using a serializer set in the child view: class HistoricalModelViewSet(viewsets.ModelViewSet): def __init__(self, **kwargs): self.list_history = extend_schema( responses={200: self.historical_serializer_class(many=True)}, )(self.list_history) @action(detail=False, methods=["get"], url_path="history", url_name="list-history-list") def list_history(self, request): serializer = self.historical_serializer_class(history_items, many=True, context=context) return Response(serializer.data) This all works fine, can view /history for all models. However when viewing /swagger everything works fine couple of times but then after about 5 reloads it errors with: myapp-api-1 | 2023-07-31 11:23:16,553 ERROR django.request log 2577 140001382692608 Internal Server Error: /myapp/schema/ myapp-api-1 | Traceback (most recent call last): myapp-api-1 | File "/usr/local/lib/python3.10/site-packages/django/core/handlers/exception.py", line 55, in inner myapp-api-1 | response = get_response(request) myapp-api-1 | File "/usr/local/lib/python3.10/site-packages/django/core/handlers/base.py", line 197, in _get_response myapp-api-1 | response = wrapped_callback(request, *callback_args, **callback_kwargs) myapp-api-1 | File "/usr/local/lib/python3.10/site-packages/django/views/decorators/csrf.py", line 54, in wrapped_view myapp-api-1 | return view_func(*args, **kwargs) myapp-api-1 | File "/usr/local/lib/python3.10/site-packages/django/views/generic/base.py", line 84, in view myapp-api-1 | return self.dispatch(request, *args, **kwargs) myapp-api-1 | File "/usr/local/lib/python3.10/site-packages/rest_framework/views.py", line …
