multiply in aggregation of django
Our View get a JSON like this : { "cart":{ "pizza": 2, "burger": 3 } } In cart is the foods name, and count of the food . My food model: class Food(models.Model): name = models.CharField(verbose_name=_('name'), max_length=100, unique=True, blank=False, editable=True) price = models.IntegerField(verbose_name=_("maximum price"), null=False, blank=False, editable=True) discount = models.PositiveIntegerField(validators=[MaxValueValidator(100)], null=False, blank=False, default=0) created_at = models.DateTimeField(verbose_name=_("created time"), auto_now_add=True, editable=False) I want to calculate the total price how I can do that with aggregation and annotate in Django ? NOTE: every food has a price that should be multiplied on count of that food. i have done this in a for loop : class OrderView(APIView): def post(self, request): srz_data = CartSerializer(data=request.data) if srz_data.is_valid(): cart_order = srz_data.data['cart'] foods = Food.objects.filter(name__in=cart_order) total_price = 0 for i,n in cart_order.items(): total_price += foods.get(name=i).price * n and done some experiment on aggregation : class OrderView(APIView): def post(self, request): srz_data = CartSerializer(data=request.data) if srz_data.is_valid(): order = srz_data.data['cart'] f = Food.objects.filter(name__in=order).aggregate(Sum('max_price')) But after a day i couldn't find a answer for this, if someone can help i will very appreciate it. thanks -
Create view that shows all objects relating to current user's department
I have the following Django model: from django.conf import settings from django.db import models class Appeal(models.Model): DEPARTMENTS = [ ("a", "DeptA"), ("b", "DeptB"), ("c", "DeptC"), # long list of departments here ] title = models.CharField(max_length=400) department = models.CharField(choices=DEPARTMENTS) author = models.ForeignKey( settings.AUTH_USER_MODEL, on_delete=models.CASCADE, related_name="appeals" ) And a view like this: from django.shortcuts import get_list_or_404, render def appeal_list_view(request): visible_appeals = get_list_or_404(Appeal, author=request.user) return render(request, "appeals/index.html", {"appeals": visible_appeals}) This shows only the appeals by the current user. I would like to change this code so that: each user is associated with a department, a user is shown all appeals from their own department (regardless of whether or not they or another user from the same department submitted it). What would be the best way to achieve this? I considered creating a group per department, which would solve the first requirement but then I'm not sure how to approach the second one. -
DJango WOPI server error when submit iframe
I'm implementing a custom wopi server to communicate a custom documenty library with office 365. The implementation is based on a django server which implements all wopi endpoints. That server communicates a cloud document library server with wopi. The problem is that when I submit the iframe to open a document with the office 365 I get the following error in javascript: [![enter image description here][1]][1] I searched for that error on the web, but all the solutions implies modify office 365 code.

How do I run two different webservers from my django project with gunicorn?
My django project has a webserver, which I run with gunicorn. Now, I have also developed a gRPC-server, which I also need to deploy, preferrably also with gunicorn. The gRPC server has a different entrypoint, e.g. within myapp.management.grpc_downloader there's the class GRPCDownloader and that has a method run_server()`. I somehow need to hand this method to gunicorn, in such a way that I can run this as a separate service in systemd, or in Docker once I containerize this. How do I achieve this? Do I just write a second wsgi.py file, e.g. wsgi_grpc.py? And what should I write in there? The current one was automatically generated. -

When I use the click method and click on the label, the message is displayed. What technique do I need to use to listen to my element using the change method? Thanks. -
How to share the django app in the Network?
We can share the Flask app in network by passing host='0.0.0.0' as argument in app.run(). Example: app.run(host='0.0.0.0') And the flask gives links for both localhost (127.0.0.1:5000) and for the network (ip_address:5000). How can I achieve same for the Django?

Database migration from MySQL to Postgres Schema
I'm currently working on migrating a Django project that was initially using MySQL to PostgreSQL. The project involves multi-tenancy with separate schemas managed by django-tenants. I'd like some guidance on the best practices for migrating the database while ensuring compatibility with django-tenants. Are there specific steps or considerations I should be aware of to successfully transition from MySQL to PostgreSQL in this scenario? Any advice or examples related to migrating databases with django-tenants and multi-tenancy would be greatly appreciated. Thanks in advance! -

How can I use Azure AppInsights with OpenTelemetry in Django
Hi I have a Django app and I wanted to connect my traditional logs with Azure AppInsights. I'm using logging lib for my logs and this piece of code occurs in 100 times in the project. import logging logger = logging.getLogger(__name__) When I checked the open telemetry Azure docs I found the following example but to use this one I have to change all the logger instances because we need to add handler for open telemetry and an exporter for Azure. Is there any way to do it without changing all the logger occurrences? logger_provider = LoggerProvider() set_logger_provider(logger_provider) exporter = AzureMonitorLogExporter.from_connection_string( os.environ["APPLICATIONINSIGHTS_CONNECTION_STRING"] ) get_logger_provider().add_log_record_processor(BatchLogRecordProcessor(exporter, schedule_delay_millis=60000)) # Attach LoggingHandler to namespaced logger handler = LoggingHandler() logger = logging.getLogger(__name__) logger.addHandler(handler) logger.setLevel(logging.INFO) -

Celery task result persistent strategy
I have a web server, a rabbitMQ server and two task processing servers in the system. Using Celery to manage the tasks. The web server needs to query the status of the tasks. Based on Celery's doc, I can choose database as result backend. In this case, should I set a database for the web server and another database for each task processing server or use one database for all these 3 servers? I also tried to use RPC as the backend, but each time the web server restarts, the status of tasks are "PENDING" after querying from AsyncResult. This is my configuration of Celery.

django and s3 doesn't use X-Amz-Algorithm on ec2
I have recently deployed a test server for one of my projects on AWS EC2, utilizing an Ubuntu server with Gunicorn and Nginx. During testing on my localhost, the Django server functioned correctly. Specifically, I have a function generating presigned URLs for files to be accessed in my frontend. These presigned URLs include the X-Amz-Algorithm. However, upon obtaining the link from my EC2 server, I noticed that it incorporates a form of signing, including AWSAccessKeyId, a Signature, and an "Expires" parameter. But not the presigned link with the X-Amz-Algorithm My objective is to achieve the same presigned URL functionality on the EC2 server.

Heroku and Django giving a 500 error when Debug is not set to False
I have been following and checking every forum post, setup instruction and video I can find. I've been checking git hub repos and comparing to my code. I cannot get my Django application to run on Heroku with DEBUG set to false and not get a 500 server error. So I wanted to reach out to ask two questions: How critical is it that I have DEBUG set to False? I have seen that it could expose information but the application is more of an online resume/portfolio site ("Hey, this is some information about me and here are some small apps I've made") Could someone take a look at my code and see what I am missing ( https://github.com/seanhayes13/codingHavoc )? I'm not using any databases for this part of the app Thank you If DEBUG is set to False, 500 error. If DEBUG is set to True, everything runs fine. I have the Heroku recommended if block setting the ALLOWED_HOSTS to ['*']. All of the static files (style sheets, pages and images) are loading fine -
