Не могу выставить правильную временную зону в Django [closed]
Я в самом начале изучения Django. Извиняюсь за глупы вопрос) Создал проект в самом начале не указал временную зону, добавил записи в базу данных и провел миграции. Как правильно исправить временную зону? Чтоб ранее добавленные записи выводились в нужной временной зоне. Пробовал изменить в settings настройку "UTC" на "UTC+6" выдает ошибку. Спасибо. TIME_ZONE = 'UTC' -
celery task received but not executed (eventlet, django)
I faced a problem that when running celery with eventlet and remote database (Redis) tasks come but are not executed, before that I used gevent and it worked correctly with both local and remote databases, but it does not have the ability to stop tasks, I tried all the options I found on the Internet and on StackOverflow, but none of them helped. I add my settings there Django settings: # settings.py CELERY_BROKER_URL = REDIS_CONN_URL + "0" CELERY_RESULT_BACKEND = REDIS_CONN_URL + "0" CELERY_WORKER_CONCURRENCY = 1000 Celery settings: import os import ssl from celery import Celery from celery.schedules import crontab os.environ.setdefault("DJANGO_SETTINGS_MODULE", "SailAPI.settings") celery_app = Celery( "SailAPI", broker_use_ssl={"ssl_cert_reqs": ssl.CERT_REQUIRED, "ssl_ca_certs": ssl.get_default_verify_paths().cafile}, redis_backend_use_ssl={"ssl_cert_reqs": ssl.CERT_REQUIRED, "ssl_ca_certs": ssl.get_default_verify_paths().cafile}, ) celery_app.config_from_object("django.conf:settings", namespace="CELERY") celery_app.conf.update( enable_utc=True, timezone="UTC", worker_concurrency=8, worker_pool="eventlet", ) celery_app.conf.beat_schedule = { "update_user_status": { "task": "user_app.tasks.update_user_status", "schedule": crontab(hour="4", minute="0", day_of_week="sat"), } } celery_app.autodiscover_tasks() The problem is that tasks that are added to the queue are not executed. I use an eventlet (because it has the ability to stop tasks that are running) and when I run it locally (Windows) with a local database (redis) it works fine, accepts tasks, executes them, stops at the command, but when I threw the code on the server (Linux) and ran … -

Why is my form calling the wrong Django view?
The flow of my app is as follows: A file is submitted on the transcribe.html page first which then redirects to the transcibe-complete.html page where the user can click to beginning transcription. Why is the 'transcribeSubmit' view being called instead of the 'initiate_transcription' view when the user clicks the 'click to transcribe' button on the 'initiate_transcription' page? Each page has their own JS file to ensure that forms are submitted separately. html: (transcribe.html): <form method="post" action="{% url 'transcribeSubmit' %}" enctype="multipart/form-data" > {% csrf_token %} <label for="transcribe-file" class="transcribe-file-label">Choose audio/video file</label> <input id="transcribe-file" name="file" type="file" accept="audio/*, video/*" hidden> <button class="upload" id="transcribe-submit" type="submit" >Submit</button> </form> (transcribe-complete): <form method="post" action="{% url 'initiate_transcription' %}" enctype="multipart/form-data"> {% csrf_token %} <label for="output-lang--select-summary"></label> <select class="output-lang-select" id="output-lang--select-summary" name="audio_language"> <option value="detect">Detect language</option> <option value="zh">Chinese</option> <option value="en">English</option> <option value="es">Spanish</option> <option value="de">German</option> <option value="jp">Japanese</option> <option value="ko">Korean</option> <option value="ru">Russian</option> <option value="pt">Portugese</option> </select> </div> <div class="transcribe-output"> <button id="transcribe-button" type="submit">Click to Transcribe</button> </div> </form> JS: const form = document.querySelector('form'); form.addeventlistener('submit', function (event) { event.preventdefault(); const formdata = new formdata(form); const xhr = new xmlhttprequest(); xhr.open('post', form.getattribute('action'), true); xhr.onreadystatechange = function () { console.log("ready state: ", xhr.readystate); console.log("status: ", xhr.status); } xhr.responsetype = 'blob'; xhr.send(formdata); }); views.py: @csrf_protect def transcribeSubmit(request): if request.method == 'POST': form = … -

Best practice to set user to admin
I am currently thinking what would be the best procedure to set a user to admin on a webapp after they have subscribed. Briefly for information: On this website users can sign up for subscriptions that give them admin rights. The payment is done via PayPal. After users have paid successfully the backend (in my case Django) receives the Paypal webhook with all necessary information about which user should be set to admin. This works so far. Afterwards a confirmation mail is sent out automatically. The problem with the whole thing is that the authprovider in the frontend pulls information like the user role from the JWT tokens. When the access token is updated with the refresh token, it gets the information like user role from the refresh token (at least that's how it's handled in Django). This means that if users have subscribed to be admins, they already are according to the database, this information reaches the frontend only when you log out and then log in again. This doesn't seem to me to be the best solution. Also problematic is that the PayPal webhook takes a few seconds longer to arrive in my backend. That is, after purchase … -

Send actual email to real recipient when developing Django app

Is it possible to split HTML view and Python back-end across different servers (IIS) in Django?
I have a Django application where I want to separate the HTML views and the Python back-end logic into two different servers for architectural and security reasons. Specifically, I want one server to handle all the HTML rendering and another server to handle the Python back-end logic like database queries, API calls, etc. Is it possible to do this while still leveraging Django's capabilities? If so, how can I achieve this split? If it is not doable, may you explain why ? Thank you in advance for your help. -
NoReverseMatch on Django URL when more than one present
I have a table with a list of data values on it. One of the columns contains a link to another page. Sometimes there could be one link, sometimes two and sometimes n. When there is only one link present the code works as expected, the pattern matches and it goes to the expected page. Whenever there is more than one link present it fails. It will still build the url correctly, I can see the full correct url in my search bar on my browser but I get a NoReverseMatch error.

Sending Audio file from Django to Vue

I have telegram api to get messages. I want to show all messages on a django web page
Using the code below I am able to get all messages AND THE parts of message ( youtube url ) that need to be shown on web page. It is now required to show this data on a django based web page. Question is where do I start. For data that is coming from telegram, how can it be shown directly on the web page. ? from telethon import TelegramClient, events, sync from telethon.tl.functions.messages import (GetHistoryRequest) from telethon.tl.types import MessageMediaWebPage, WebPage, WebPageEmpty client = TelegramClient(session_name, api_id, api_hash) client.start() channel_entity=client.get_entity(channel_username) posts = client(GetHistoryRequest( peer=channel_entity, limit=100, offset_date=None, offset_id=0, max_id=0, min_id=0, add_offset=0, hash=0)) for message in client.iter_messages(chat, reverse=True): if type(message.media) == type(None): continue if not type(message.media) == MessageMediaWebPage: continue if type(message.media.webpage) == WebPageEmpty: continue if hasattr(message.media.webpage, 'display_url'): print('+++ display_url ', message.media.webpage.display_url) Can I call a for loop inside the views. Another concern is, every time the page loads it will query data from telegram. And this can take long time. Is their a way to cache data that comes from an api so that subsequent reads are coming from the cache. -

The most recent rows in for each type/agent in Django
I have a table with lots of data. This table is written by some scripts. It works like a "check in", where each agent is checking in in some period of time. It looks like below. id agent status timestamp 1 tom ok 2023-03-16 12:27:03 2 jeff degraded 2023-08-31 00:01:13 100 tom ok 2023-10-03 12:00:00 101 jeff ok 2023-10-03 11:59:00 I'd like to pick the most fresh line per each agent. So in above example I'd like to get row 100 and 101. I tried many different ways but still not getting what I want. I use MySQL, so distinct is not for me this time. On one hand there is a way to make distinct values per agent, like below: AgentCheckin.objects.all().values('agent').distinct() But it's just a name of an agent. I need to get whole query set with all the information. I think this kind of use case should be somehow common in multiple web apps, but looking here is SO, it's not that common with ultimate answer. -

My Fullstack app is having issues after being deployed with Digital Ocean
So I developed fullstack application which has Django for backend and React for frontend. I am using Digital Ocean as host for my Django project and Railway for my React project. Locally everything works perfectlly but once I deployed it, thats where it started giving some errors. I am new to DevOps and deploying projects in general so bear with me. I checked my deploy loggs and everything seems to be in order, my url is also correct, which points to my digital ocean server app and works fine I tested it with postman. To give you an example of the issue , user creates a message and then after its done it redirects him to the home page. Instead of seeing the message on home dashboard, its basically empty. Then when I navigate away and come back to home page message is there, but then when I do navigate away and come back again to home page message is gone. So I have this really weird error which I really dont understand why is it occouring. So I am turning to stackoverflow community for help. Could it be because of plan package that I have on digital ocean? Like … -
