django ModelForm - initial form values
I want to create an object instance where I set the (not unique) uid myself. I want to suggest the next "free" uid because that's the most used use case. class TestForm: last_uid = Process.objects.order_by("-uid").first().uid If I use the form the first time the value in last_uid is correct (let's say it's 42), but if I create a second instance, the last_uid is still the same value (again 42, but I would expect it to be 43). Do I have to hand the last_uid to the form and extract it in __init__() in order to make sure it is generated correctly on every new call of the form? -
Redis and Django - Working with localhost redis, Broken pipe when using redis on another host
I am running a local dev environment for Django and have separated out services like DB (MariaDB), RabbitMQ and Redis onto another host instance. Everything is working as expected Except for Redis, Django throws...: python3.11/site-packages/redis/connection.py", line 446, in send_packed_command raise ConnectionError(f"Error {errno} while writing to socket. {errmsg}.") redis.exceptions.ConnectionError: Error 32 while writing to socket. Broken pipe. ERROR:django.request: Internal Server Error: / (2023-11-09 07:29:04; log.py:224) However if I configure Django to use a localhost redis-server instance it works ok. The redis instance on the other host is accessible to the django server, i.e. I can connect to it using redis-cli -h devservices.orb.local from the django server (I'm using OrbStack to provide the server hosts, if that's relevant.) -
When accessing the database in the django websocket, incorrect data is returned
I am writing a websocket for a card browser game on django and channels. When the round ends, the results are counted, the calculation itself works correctly and even saves the calculations in the database. But at the end of the next round, when accessing the database, it returns the data that was before the previous round. That is, if at the beginning of the first round everyone has 0 points, at the end someone has 3 points, at the end of the next round 0 points are returned when calculating the result from the database. Although at the beginning of the same round, all players were sent data received from the database that someone had 3 points. I can't understand why this is happening, I didn't connect any caching. Here you can see the code of the entire project. Below is the code of the websocket method for calculating the results. The problem is in the data returned to players: async def calculate_results(self, event): game = await database_sync_to_async(Game.objects.get)( id=self.game_id ) players = await database_sync_to_async( lambda: list(Player.objects.filter(game=game)) )() self.round_num = await get_round_num(game) for player in players: round = await database_sync_to_async(Round.objects.get)( game=game, round_num=self.round_num ) association = await database_sync_to_async(Association.objects.get)( round=round, player=player ) … -

Add user to group to specific database does not work
I am struggling to make the following code works for me. user = User.objects.using(data[‘db_name’]).get(pk=1) group = Group.objects.using(data[‘db_name’]).get(pk=2) user.groups.add(group) I can see that Django creates one record to auth_user_groups in the default database but not in the data[‘db_name’]) database. Interestingly, user and group objects are coming from data[‘db_name’] database. Can anyone advise me how to add new record to data[‘db_name’] database successfully? -
Detach Python Selenium from Gunicorn
I'm fairly new to gunicorn, Is there any possible way that allow me to run selenium browser outside of gunicorn enviroment? For example, I would like to update my Django application without interfering with a running selenium driver in the background. from selenium import webdriver from selenium.webdriver.chrome.service import Service from selenium.webdriver.chrome.options import Options def selenium(request): options = Options() options.add_argument("--headless=new") options.add_experimental_option("detach", True) chrome_path = "chrome/driver/chromedriver" driver = webdriver.Chrome(service=Service(executable_path=chrome_path) ,options=options) driver.get('https://example.com/') return HttpResponse(status=200) Selenium driver will stay active until, I restart gunicorn to update my code. Is there any other way to do so without driver shutting down? I've tried to detach selenium. and I've though that will be enough to allow driver to be detached from gunicorn. But that didn't work out. I'm updating my code through git and using "systemctl restart gunicorn" to allow it to update. -
When deploying django app, manage.py cant find views.py
I am trying to deploy a simple Django app that makes a user login and then serves a "hello world" on success. I use white noise for static. The web service builds correctly, but when deploying, I am getting the error module views.py can not be found. I can not understand why though as all paths seem to be correct.

Many to Many relation between two databases Django
I am building a separate Django project to handle a chat system, I already have a different Django project for everything else (user login info and serves API that does not relate to chat). In this chat project, it has a model class ChatRoom(models.Model): rmid = models.BigAutoField(primary_key=True) name = models.CharField(max_length=256) people = models.ManyToManyField(to=User, blank=True) timestamp = models.DateTimeField(auto_now_add=True) And a database router: class UserAuthRouter: def db_for_read(self, model, **hints): if model._meta.app_label == 'auth': return 'database_with_django_auth_models' return None def db_for_write(self, model, **hints): if model._meta.app_label == 'auth': return 'database_with_django_auth_models' return None This allows me to use the same user login info from the main project since I have connected the database in settings. When I try to access ChatRoom model, I believe because the many-to-many field is relating to User model in the Auth lib/module, it causes this error as it is routed to use the other database: Django.db.utils.ProgrammingError: (1146, "Table 'database_with_django_auth_models.apps_chat_chatroom_people' doesn't exist") But the apps_chat_chatroom_people datatable is in the database that contains the ChatRoom schema, (i.e. the second database that is going to be used for the chat system) What is the proper way to handle this? I want to be able to use the same login credentials. -
how to create a multiple ForeignKey fields in a view create and save to database
First of all, I appreciate your help and time I would like to save all the 'equipamento' fields in the database instead of just one!

How to use ipdb debugger on Kubernetes environment
Traditionally I use ipdb as a debugger when I work on django. Here I want to use ipdb to debug so I put "import ipdb; ipdb.set_trace()" in my code. But on kubernetes I don't really know how to do it. I do kubectl attach pod-name -c container-name -i -t to access my django container, I see that the execution of the code stops on my breakpoint ok, BUT it continues and I get the error: "self.quitting: raise BdbQuit\nbdb.BdbQuit", the classic error that occurs when the code continues despite the breakpoint. It doesn't stop there, it continues straight on. How to properly use ipdb in a kubernetes env, any ideas ? Thank you ! -
