psql version does not change to 12 even after upgrade
I have acquired an image of postgre sql and i have imported data into the a table my_spo_stats in database music. I intended to build a webpage with Django with this being my database, so i started in this container building Django projects. However, when i ran python3 manage.py makemigrations, I got the following error: raise NotSupportedError( django.db.utils.NotSupportedError: PostgreSQL 12 or later is required (found 11.9). but i did pull the image specifying the version to be 12. Regardless, i tried to upgrade my psql . i did sudo apt-get update. sudo apt-get install postgresql-12 postgresql-server-dev-12, and (in case of any need for closer examination here) the output was invoke-rc.d: could not determine current runlevel invoke-rc.d: policy-rc.d denied execution of start.

ModuleNotFoundError: No module named 'school.message_test'

I also tried using it for the top level, that is from ..message_test.routing import websocket_urlpatterns but it doesn't work because asgi doesn't allow it the path is absolutely correct, what can you tell me? photo of the full project path -
Django: Convert IntegerField to ForeignKey
I have a database with this django model: class System(models.Model): system_id = models.IntegerField(primary_key=True) constellation_id = models.IntegerField() It already has some data, and EVERY row of the table has constellation_id. And now I created a new table with data: class Constellation(models.Model): constellation_id = models.IntegerField(primary_key=True) Is it possible to refactor constellation_id of System model from IntegerField into ForeignKey? All of the constellation_ids in System table exist in Constellation table. -

Asynchronous processing when using Celery in a Django application (Heroku)
I am developing an application that uses the Whisper API to convert uploaded audio files into text. I am trying to use Celery for asynchronous processing, but I can't seem to reference the media file properly.

How can I get a batch of frames from consumers.py?
Currently, I am working on a computer vision project that involves object detection and real-time frame streaming using opencv and django. To accomplish this, I am utilizing django-channels. However, I have encountered a new challenge where I need to perform video classification. This requires sending a batch of frames to the model. Can you provide any guidance on how to approach this issue? I added a button on the front-end. What I expected was to obtain a single timestamp from the back-end consumers.py. What I got was the timestamp of the start frame till the timestamp of the frame where the button was clicked. Here is an example image of it In the consumers.py file, I'm utilizing the OpenCV library to iterate through the frames, and then I'm transmitting that data to the websocket client. Here is an example of the code (I have also provided the comments for better understanding). # Import the 'cv2' module, which is the OpenCV library for computer vision tasks. import cv2 # Import the 'json' module for working with JSON data. import json # Import the 'asyncio' module for asynchronous programming support. import asyncio # Import the 'datetime' module for working with date and … -
How to take images from Media folder from another domain?
I have 2 domains: naiuma.com and jp.naiuma.com. I have uploaded all images to Media Folder on naiuma.com and now I want to access them on jp.naiuma.com.

Please let me know, what should I do to connect thumbnail = models.ImageField with the old, main naiuma.com domain and it's hosting? Thanks. -
Django; add integer primary_key in production
We have a running instance of a Django Backend. On a few model we used an CharField as an Primary Key because it was the best solution for the old requirements. Now we need to add a basic int id like id = models.AutoField(primary_key=True) and let the old charfield remain as primary_key=False. I removed the primary_key=True Flag from the old primary key attribute and triggerd ./manage.py makemigrations. If I dont declare any primary key Django is generating its normal id like mentioned above. But after trigger, Djang asks for default values for old entries of this model like: It is impossible to add a non-nullable field 'id' to anrede without specifying a default. This is because the database needs something to populate existing rows. Please select a fix: 1) Provide a one-off default now (will be set on all existing rows with a null value for this column) 2) Quit and manually define a default value in models.py. Becaus its an unique Field, I cant use any static content. So how can I still make migrations without delete old migrations? -

annotation with a table referred to by content_type + object_id in DjangoORM
So issue is I need to filter by title field that in many others tables. class Model uses contenttypes framework in django. It refers to several tables that have a title field (field I want to filter by) class Model(models.Model): content_type = models.ForeignKey( ContentType, on_delete=models.CASCADE, limit_choices_to={'model__in': ('model1', 'model2', 'model3', 'model4', 'model5')}, ) object_id = models.CharField(max_length=36) content_object = GenericForeignKey('content_type', 'object_id') Every table that has the title field has GenericRelation(Model, related_query_name='elements') class model1(models.Model): # and etc for model2, model3... title = models.CharField(max_length=255) myfield = GenericRelation(Model, related_name_query='elements') First I Tried Model.objects.annotate(title=F('elements__title')). But for some reasons it does not work for me because it joins only one table. It makes sence because anyway I need to handle these strings with Coalesce. So I figured it out by create my own SQL query but I cannot convert it to DjangoORM here is the query SELECT "mm"."id", COALESCE("model1"."title", "model2"."title", "model3"."title", "model4"."title", "model5"."title") AS "title" FROM "Model" AS "mm" LEFT OUTER JOIN "model1" AS "model1" ON ("mm"."object_id" = "model1"."id") LEFT OUTER JOIN "model2" AS "model2" ON ("mm"."object_id" = "model2"."id") LEFT OUTER JOIN "model3" AS "model3" ON ("mm"."object_id" = "model3"."id") LEFT OUTER JOIN "model4" AS "model4" ON ("mm"."object_id" = "model4"."id") LEFT OUTER JOIN "model5" AS "model5" ON ("mm"."object_id" … -
