How do I properly set PYTHONPATH when invoking the Django Python shell?
I'm using Python 3.9.9 for a Django 3 project. I would like to invoke my Python shell, via "python3 manage.py shell", so I have set these variables ... $ echo $PYTHONSTARTUP /home/myuser/cbapp/shell_startup.py $ echo $PYTHONPATH/myuser /home/myuser/cbapp/ My startup script is very simple ... $ cat /home/myuser/cbapp/shell_startup.py from cbapp.services import * from cbapp.models import * However, when I change to my project directory, activate my virtual environment, and attempt to invoke the shell, I get these errors complaining about not being able to find Django ... $ cd /home/myuser/cbapp $ ./venv/bin/activate $ python3 manage.py shell Traceback (most recent call last): File "/home/myuser/cbapp/manage.py", line 10, in main from django.core.management import execute_from_command_line ModuleNotFoundError: No module named 'django' The above exception was the direct cause of the following exception: Traceback (most recent call last): File "/home/myuser/cbapp/manage.py", line 21, in <module> main() File "/home/myuser/cbapp/manage.py", line 12, in main raise ImportError( ImportError: Couldn't import Django.

Sending Audio file from Django to Vue
I'm trying to send gtts generated audio file from Django to Vue via HttpResponse. Django's views.py: f = open('path/of/mp3/file', 'rb') response = HttpResponse() response.write(f.read()) response['Content-Type'] = 'audio/mp3' response['Content-Length'] = os.path.getsize('path/of/mp3/file') return response and when vue receives the response data, it is like the below: data: '��D�\x00\x11C\x19�\x01F(\x00\x00\x04 �&N�""""���ޓ�������\x7F���B\x10���w�����…���_�F��1B��H���\x16LAME3.100�����������������������' # and so on I guess it is because the bytes have been converted to string over the transfer and I have to convert it back to the audio file. But no matter whether using blob or other suggested methods, I could not convert it to an mp3 file to be played in javascript. How could I achieve this? -

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 … -

However, I need the results by week where the week starts on Saturday. Is there a simple way to do this or should I create a week columns in the table and save it there? Thanks! -
Can't edit anything in Django CMS due to cross-origin error
About three months ago, I upgraded our old Django and CMS application to the (then) latest LTS versions (4.2.3 for Django, 3.11.3 for django-cms). After the upgrade, I got the following error when I tried to edit anything from the CMS toolbar or the CMS plugins after a successful login: SecurityError: Blocked a frame with origin "http://localhost:8000" from accessing a cross-origin frame. A short Google search later I was able to fix the issue by setting the CSRF_TRUSTED_ORIGINS in settings.py (depending on the environment). This worked like a charm until a few weeks ago, when suddenly the same error appeared again. This happens on all our environments - including local - despite the fact that nothing new was deployed since the beginning of July '23. First, I tried everything in this guide: https://noumenal.es/notes/til/django/csrf-trusted-origins/ Our staging and production django app is behind a proxy, so I verified that HttpRequest.is_secure() returns True and the X-Forwarded-Proto header is set to https in the production environment. But this happens also on my local machine, where there is no HTTPS. I also verified that the CSRF cookie value and the CSRF token param in requests are, in fact, the same. Then I tried to install … -

Django project not running after I have updated the python version of the system
I had created a django project a couple of months ago. Now I wanted to do a new project and updated the python version of my system and the privious project is not working.

It shows this error. enter image description here ImportError: Couldn't import Django. Are you sure it's installed and available on your PYTHONPATH environment variable?
