Django, sqlite to mysql migration, json decoder issue with migrated pages
I have an early and simple django project, to get things started we were using a sqlite database during setup. Someone else created some django pages with various plugins, but since these are actual pages and not templates, they are stored in the database. We realized that we should've migrated to mysql before making these pages and now we have 2 options. 1, we migrate and he builds the pages again which is time consuming, or 2, we find a way to migrate the sqlite database contents to mysql. I've been trying to figure out the second option, migrating our sqlite db to mysql. I've scoured google and nothing has been as simple as I would like, but I've been able to create as sql dump file, follow some steps to alter the format of said file, and dump said file into the new mysql database. However, while the data is there and I can access the admin and new pages, the migrated pages all run into an error when I try to view the pages or copy & paste them in the django admin. And for clarity, I created an almost blank page before the migration (tried this a … -

How to access child model from a parent model using Django ORM?
Here are my models: class Collection(models.Model): title = models.CharField(max_length=255) featured_product = models.ForeignKey( 'Product', on_delete=models.SET_NULL, null=True, related_name='+') class Product(models.Model): description = models.TextField() unit_price = models.DecimalField(max_digits=6, decimal_places=2) inventory = models.IntegerField() collection = models.ForeignKey(Collection, on_delete=models.PROTECT) I have two models here, one of which is the parent (Collection), and the other is the child (Product). So if I need to filter the queryset based on the title attribute of the Collection class, I can type a queryset like this. query_set = Product.objects.filter(collection__title = 'beauty') Notice: Here I am accessing the parent using the child; the question is, how can I do the opposite? I tried this line of code but i got an error saying:Cannot resolve keyword 'product_set' into field. query_set = Collection.objects.filter(product_set__inventory__lt=10) -

Webhooks from Azure to Django. Validation problems

FastAPI + pytest unable to clean Django ORM
I'm creating a FastAPI project that integrates with the Django ORM. When running pytest though, the PostgreSQL database is not rolling back the transactions. Switching to SQLite, the SQLite database is not clearing the transactions, but it is tearing down the db (probably because SQLite uses in-memory db). I believe pytest-django is not calling the rollback method to clear the database. In my pytest.ini, I have the --reuse-db flag on. Here's the repo: https://github.com/Andrew-Chen-Wang/fastapi-django-orm which includes pytest-django and pytest-asyncio Assuming you have PostgreSQL: Steps to reproduce: sh bin/create_db.sh which creates a new database called testorm pip install -r requirements/local.txt pytest tests/ The test is calling a view that creates a new record in the database tables and tests whether there is an increment in the number of rows in the table: # In app/core/api/a_view.py @router.get("/hello") async def hello(): await User.objects.acreate(name="random") return {"message": f"Hello World, count: {await User.objects.acount()}"} # In tests/conftest.py import pytest from httpx import AsyncClient from app.main import fast @pytest.fixture() def client() -> AsyncClient: return AsyncClient(app=fast, base_url="http://test") # In tests/test_default.py async def test_get_hello_view(client): """Tests whether the view can use a Django model""" old_count = await User.objects.acount() assert old_count == 0 async with client as ac: response = await ac.get("/hello") … -

Cannot establish incoming connections to docker container
I have a Django app running on docker that requires access to the Azure Storage Accounts from it. It runs fine when the Django server runs from the host computer, but, the connection to the Azure Storage Account fails when running from the container. I guess, somehow Docker is blocking the incoming traffic, as I can perform ping www.google.com.br from the container, but I never get the response back. I used to work with this very same app from a MacOS laptop with no issues (the app establishes connection to the Azure Service), but it does not works since I changed my development setup to Linux (Linux KDE Neon). Any ideas on how can I allow docker containers to receive traffic from the internet? Thanks. This is the error I see that indicates me that Azure Storage Account connection is not allowed (plus the fact this works when I run the same from my MacOs notebook). <urllib3.connection.HTTPSConnection object at 0x7f1286429e10>: Failed to establish a new connection: [Errno -3] Try again')> This is my Docker compose file: the Celery workers are the containers attempting to establish connection with Azure: `version: '3.8' services: web-server: build: ./apps ports: - 8000:8000 - 5678:5678 - … -

Is there a way to use an abstract value in field in Django Framework?

I've tried to do it like: class Food(models.Model): order = models.OneToOneField(Order, on_delete=CASCADE) class Meta: abstract = True But that allows to have both 'Burger' and 'Pizza' be connected to 'Order', and that's not what I need. -
Jenkins pipeline does not create postgresql_data volume but running docker compose up -d commad manually creates volumes
I'm pretty new to whole docker,docker-compose,jenkins and whole CI-CD concept. So, I may be missing a very simple point. My application is a django web app with postgresql and nginx. If I run docker compose build and docker compose up -d, 3 containers runs and docker volumes are created without any problems. Now I am trying to run these 3 containers with jenkins. I clone my app's repo to jenkins and run docker compose build and docker compose up -d in my pipeline. My app works, static volume is created but postgresql_data docker volume is not created and it's gone if I restart my host machine I thought this might be because of user permissions but the static volume is created by the same jenkins task.

Considerations of building an Android service as system app (OEM)
I'm working on an OEM project where we need a background service (no UI) to be working continuously. Of course it'll be an app signed with the OEM key, so it shouldn't be any trouble related to background services Android's restrictions. But, as it is the first time developing this, is there any consideration regarding the implementation of the service lifecycle and workflow? Plus, anything important to consider regarding the testing flow of the project? Thank you, any help related to OEM-apps development will be much appreciated.
