Issue with creating new pigeon and his parent records in a Django form
I am new to programming and currently learning Django. I am working on a web application where users can register new pigeons into a database. The registration form includes fields for the pigeon's name and a long dropdown menu with all the existing records for the father and the mother, which becomes quite tedious with many pigeons. Is there a strategy to solve this? Something like search fields to allow the user to search and select the father and the mother? And if parents do not exist, to add functionality to register them from there, similar to the admin form? If the father or mother doesn't exist in the database, the user should be able to create a new parent record directly from the main registration form without leaving the page. I have implemented the following model for the Pigeon: `python from django.db import models class Pigeon(models.Model): GENDER_CHOICES = ( ('male', 'Male'), ('female', 'Female'), ) name = models.CharField(max_length=100) gender = models.CharField(max_length=10, choices=GENDER_CHOICES) father = models.ForeignKey('self', on_delete=models.SET_NULL, null=True, blank=True, related_name='children_set') mother = models.ForeignKey('self', on_delete=models.SET_NULL, null=True, blank=True, related_name='children_set') def __str__(self): return self.name ` I'm facing an issue where I can't seem to create new parent records from the main registration form.

Resolving Celery Timeout Issues on Heroku: 504 Errors for Long-Running Asynchronous Tasks
I have a Django v5.0.6 application (Python v3.12) in which I integrated Celery v5.4 to run asynchronous tasks, such as generating images via the OpenAI API, which takes about 2 minutes. The entire setup is deployed on Heroku. Here is the content of my Procfile: web: gunicorn mngrs_backend.wsgi --timeout 600 worker: celery -A mngrs_backend worker -l info --time-limit=7200 However, after 30 seconds, I get the following error in the logs: I am looking to increase the delay to avoid a timeout. Here are the attempts I made without success: Added --timeout 600 in the gunicorn command in the Procfile Added --time-limit=7200 in the celery command in the Procfile Added a timeout to the API request: requests.post(url, json=payload, headers=headers, timeout=600) Modified the configuration in celery.py app = Celery("mngrs_backend") app.conf.update( task_soft_time_limit=60 * 10, task_time_limit=60 * 12, ) Added in the project settings: CELERY_BROKER_TRANSPORT_OPTIONS = { "visibility_timeout": 60 * 60 * 2, # 2 hours } Locally with Celery, I do not have any timeout issues. I contacted Heroku support, but they told me the problem is with my Celery configuration. Does anyone have a solution? -

How to serialize snake_case model fields to camelCase in django rest framework
I'm adding REST API endpoints to my existing Django application. I'm using DRF ModelSerializer.

How can I build the Backend for a reminding feature like in Google Calendar using django and python?
I need to implement a feature that has a recurring nature to it. A user will be able to set a reminder and that reminder will have a frequency to it. The types of frequency are as follows: Daily Weekly Biweekly Monthly Bimonthly Quarterly Half Yearly Yearly Biyearly And to top it off I also need to allow the user to add a "remind me {x} hours before {the scheduled reminder}" Please HELP! Can somebody explain to me the technologies I'll need to use to build a feature like this? To be more precise—to build the backend for it. I did some research and found out about Celery & Redis as the way to go besides a Cron job. And then upon finding out about Celery-Beat I gave up. Why? Because it's all so very confusing and complex. I'm not sure if this is the right way, or not. It seems to me like this could be made inefficiently very easily, if done by brute-force, or very complex, if done efficiently. -
Intermittent Process Stoppage with Requests Library in Django App on Google Compute Engine When Using Gemini API

How to handle permissions of media files uploaded in django?
Need urgent help Hi guys, need a help about a project. How can I handle media files securely in django and Django rest framework? Basically the files should be private. For example, suppose this is a digital product website, where the buyer will only get access to the file if he/she purchases the digital product. Otherwise, the product file should be private. I can handle the permissions of drf and django views. But usually the media files are not private, the media files can be access via url easily. If one buyer purchases and share the file link with others everyone can download even without creating an account. So how can I handle this? Also how can I handle video files, that needs to be streamed to the frontend. Thanks -

Celery: attach custom logger to default celery handler (logfile)
I would like to have a logger that can be used both in django and in celery. When used by django it should print to console, while when used from a celery task, I would like it to output using the default celery handler (in my case, it dumps to a file specified by the --logfile cmd line argument). This is especially useful for helper functions that are used by both the django server and celery tasks. This is what I have in my settings.py file: LOGLEVEL = os.environ.get("LOGLEVEL", "info").upper() LOGGING = { "version": 1, # the dictConfig format version "disable_existing_loggers": False, # retain the default loggers "handlers": { # console logs to stderr "console": { "class": "logging.StreamHandler", "formatter": "verbose", }, "django.server": DEFAULT_LOGGING["handlers"]["django.server"], }, "formatters": { "verbose": { "format": "[{asctime}]|{levelname}| {message}", "style": "{", }, "django.server": { # "()": "django.utils.log.ServerFormatter", "format": "[{asctime}]|{levelname}| {message}", "style": "{", }, }, "loggers": { # default for all undefined Python modules "": { "level": "WARNING", "handlers": ["console"], }, # Our application code "app": { "level": LOGLEVEL, "handlers": ["console"], # Avoid double logging because of root logger "propagate": False, }, # Default runserver request logging "django.server": DEFAULT_LOGGING["loggers"]["django.server"], "django.channels.server": DEFAULT_LOGGING["loggers"]["django.server"], }, } In my "app" logger, I have … -
how to Implement non-blocking, sequential AI moves in a multiplayer chess game in django channels?
I'm developing a website to play a special with kind of chess with React and Django. It pretty much requires two games to be played at the same time. The website allows to add AI players, so the common scenario is to have board 1 (human vs AI) and board 2 (AI vs AI). I want the computer players to behave in a manner that they play a move, wait a second, then let another one play, not blocking other games. The problem is that the following code makes the entire AI vs AI game play in a blink of an eye and makes it impossible to send and receive any event (even the game.start event does not get sent). This is my code that triggers the computers playing against each other: for game in started_games: await self.channel_layer.group_send( self.room_group_name, {'type': 'game.start'}) if self.is_ai_turn_in_game(game): if game.gamemode == GameMode.CLASSICAL.value: board = chess.Board(fen=game.fen) else: board = chess.variant.CrazyhouseBoard(fen=game.fen) print(self.is_ai_turn_in_game(game)) while self.is_ai_turn_in_game(game): await self.handle_ai_turn(game, board) await self.send_move_to_clients(game) self.send_move_to_clients processes some data, then calls await self.channel_layer.group_send( self.room_group_name, {'type': 'game.move', 'message': response_data} ) which executes the following code: async def game_move(self, event): move = event['message'] await self.send(json.dumps(move)) await asyncio.sleep(1) I am wondering if I should use a … -
Is there an option to use nginx instead of traefik?
The "Select a front-end web server/proxy to use" option seems to be gone. I'm using cookiecutter-django's docker compose setup. I'd rather use nginx (a more familiar technology without the excessive abstractions of traefik).
