Can I trigger Celery task on table update in Django?
For example, I have a model: class SomeModel(model.Model): is_active = BooleanField(default=False) ... Is it possible to trigger Celery task when is_active changes to True? The most important thing here is that I need to trigger it regardless of the way is_active changed, whether it changed via shell, admin panel, api call etc. The DB I use is psql. -
Is there any way to make a manual join using Django ORM?
lets say I have the following models: class ModelA(models.Model): pass class ModelB(ModelA): pass class ModelC(models.Model): model_a = models.ForeignKey(ModelA) class ModelD(models.Model): model_c = models.ForeingKey(ModelC) And I need to filter all the instances of ModelD that have a relation in ModelB. Is there any way to remove the unnecesary joins in the query that the queryset will produce ? ModelD.objects.filter(model_c__model_a__model_b__id__isnull=False) If there's any way to make a filter like this: ModelD.objects.filter(model_c__model_b__id__isnull=False) I know how to make the query on SQL, but for terms of readabilty and code maintenance I would like to know if there's any way to make the manual join or to remove that intermediate join. Thanks in advance for the replies ! -
Django: list view not recognized
I have to do this project of classified ads for Coursera. Essentially every user can post, update and delete advertisements. The problem is that even if the objects are correctly stored (I checked tables and objects via admin and manually with the command line), the ad list doesn't show up and it tells "There are no ads in the database." even though there are ads. I'm looking everywhere but I cannot find the error. Here's the code: ad_list.html: views.py: from ads.models import Ad from ads.owner import OwnerListView, OwnerDetailView, OwnerCreateView, OwnerUpdateView, OwnerDeleteView class AdListView(OwnerListView): model = Ad class AdDetailView(OwnerDetailView): model = Ad class AdCreateView(OwnerCreateView): model = Ad fields = ['title', 'text', 'price'] class AdUpdateView(OwnerUpdateView): model = Ad fields = ['title', 'text', 'price'] class AdDeleteView(OwnerDeleteView): model = Ad owner.py: from django.views.generic import CreateView, UpdateView, DeleteView, ListView, DetailView from django.contrib.auth.mixins import LoginRequiredMixin class OwnerListView(ListView): """ Sub-class the ListView to pass the request to the form.

Django reCAPTCHA with multiple forms
I have a DJANGO application where I protect forms with reCAPTCHA v2 invisible. I have no issue protecting 1 form, everything works well and I have been using this feature for quite some time. However, if I have 2 forms on the same page, EACH protected with their own captcha, it doesn't work. Here's what happens: OK: both forms have their individual onSubmit_xxxand onSubmit_yyy function (with a different widget uuid) OK: both forms get their "submit" event properly redirected to the verifyCaptcha_xxx or verifyCaptch_yyy function NOK: after grecaptcha.execute(), ALWAYS the onSubmit_xxx function (of the first form) is executed (with the wrong widget uuid) I am using Django 2.1 with Python 3.5 Any hints? Thanks a lot!! -

Django usage of ForeignKey
I have this micro ticket "system" \\models.py class Ticket(models.Model): user = models.ForeignKey( settings.AUTH_USER_MODEL, default=None, null=True, on_delete=models.CASCADE, ) title = models.CharField(max_length=200) description = models.TextField() creator_adress = models.GenericIPAddressField(null=True) start_date = models.DateTimeField(default=timezone.now) ticket_waiting = models.BooleanField(default=True) ticket_solved = models.BooleanField(default=False) reopened_counter = models.IntegerField(default=0) ... Until now, only one message (when the user opens the ticket) can be sent by the user, which will be forwarded to the admin. But the admin and the user can't write any other messages back and forth under the ticket yet. If you use a new model for this, which is connected to every single ticket like so? class TicketMessages(models.Model): ticket = models.ForeignKey(Ticket, on_delete=models.CASCADE) admin_message = models.TextField() user_message = models.TextField() What is the best way to implement this? Thank you very much :> -
Uvicorn async workers are still working synchronously
Question in short I have migrated my project from Django 2.2 to Django 3.2, and now I want to start using the possibility for asynchronous views. I have created an async view, setup asgi configuration, and run gunicorn with a Uvicorn worker. When swarming this server with 10 users concurrently, they are served synchronously. What do I need to configure in order to serve 10 concurrent users an async view? Question in detail This is what I did so far in my local environment: I am working with Django 3.2.10 and Python 3.9. I have installed gunicorn and uvicorn through pip I have created an asgi.py file with the following contents import os from django.core.asgi import get_asgi_application os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'MyService.settings.local') application = get_asgi_application() I have created a view with the following implementation, and connected it in urlpatterns: import asyncio import json from django.http import HttpResponse async def async_sleep(request): await asyncio.sleep(1) return HttpResponse(json.dumps({'mode': 'async', 'time': 1).encode()) I run locally a gunicorn server with a Uvicorn worker: gunicorn BudgetService.asgi:application -k uvicorn.workers.UvicornWorker [2022-01-26 14:37:14 +0100] [8732] [INFO] Starting gunicorn 20.1.0 [2022-01-26 14:37:14 +0100] [8732] [INFO] Listening at: http://127.0.0.1:8000 (8732) [2022-01-26 14:37:14 +0100] [8732] [INFO] Using worker: uvicorn.workers.UvicornWorker [2022-01-26 14:37:14 +0100] [8733] [INFO] Booting worker … -
Passing variables to extended template
I'm having templates that later my all other templates extend. Most basic template is base.html. It includes the navigation bar: {% include 'includes/navigation.html' %} Navigation bar should display different titles depending on the role set: {% if role == "admin" %} <p class="title">Welcome to the Administrator Dashboard!</p> {% elif role == "user" %} <p class="title">Welcome to your Dashboard!</p> {% endif %} From base.html a few other layouts extend, for example 2_column.html {% extends "layouts/base.html" %} {% block content %} <div class="block block_main col-md-9"> {% block block_main %}{% endblock block_main %} </div> <div class="block block_side col-md-3"> {% block block_side %}{% endblock block_side %} </div> {% endblock content %} And only from these templates I build all my other html files. For example login.html: {% extends "layouts/2_column.html"%} {% block block_main %} <h3 class="block_title">Login</h3> <form method="post"> <!-- Form --> <div class="input-group"> <label for="file_id">Username</label> <input type="text" id="username"> </div> </form> {% endblock block_main %} I cannot figure out how to pass the role correctly all the way up to the navigation.html. Is that even possible? I've tried to wrap up the whole template in: {% with role="admin" %} {% endwith %} but if {% extends ... %} is inside it tells me that the with … -
submitting a value to Django view through admin SB2 sidebar
I am using the SB admin2 bootstrap dashboard template, and there is a side bar with collapse menus that I am planning on using.

Django endpoint executes but never returns Response
The endpoint used to work just fine, but lately as I tested it, it does all the logic it has to do, but when it comes to return the HttpResponse() it never does. I got some logs on my code (the print in this example) and I get to the line before returning the Response but it just doesn't return it, it's like it gets stuck after doing the print(). def endpoint(): # some logic here... print('I got here') return HttpResponse('...', status=200) Also this happens when the "logic" inside it gets a massive amount of data as input, eventhough it executes just fine, it never returns. With smaller data as input it works perfectly and returns. Honestly I've no idea why this is happening since there aren't any errors showing up. -

Improve db performance in DetailView
I want to improve speed and performance of my blog and avoid the duplicate queries. I'm using the Django debug toolbar for that btw. Note: I'm indexing my models. Here are the models I have: class Post(Model): name ... ... author = ForeignKey(Author..) comments = ManyToManyField(Comment...) ... class Comment(Model): content... ... author = ForeignKey(Author...) replies = ManyToManyField(Reply...) class Reply(Model): content... ... author = ForeignKey(Author...) ... Is there any way to improve the speed of the post detail page, it's above 2 seconds before caching. and 1 second after caching. Here is my try: class PostDetailView(HitCountDetailView): ... def get_queryset(self): return super(PostDetailView, self).get_queryset().select_related().prefetch_related() .... Also I'm using the django-hitcount to track visitors, but it's quite slowy, any fix for that too. -

How to update Celery tasks in production?
I have a Django application and some scheduled tasks handled by Celery. I use RabbitMQ as a message broker. Locally, everything works as supposed, but in production, celery worker runs old tasks that don't even exist anymore. I've tried adding worker restart to my celery worker Kubernetes-deployment -file, but that didn't make any difference. Here's what I tried: spec: containers: - name: celery-worker command: ["/bin/sh"] args: - -c - >- celery -A project_name -b 10.0.240.179 worker -l info && celery restart -A project_name -b 10.0.240.179 worker -l info This runs the worker pod without errors but it still uses the old, already deleted tasks.
