I'm getting a 503 error when I upload an image to a pre-trained model and try to get output using python + Django on a shared web host
Background: *Beginner here. * I made a simple app with some basic models and trained it to distinguish happy and sad faces. I made this and ran it in a local development server with Django which worked perfectly and I was even able to display the image after getting a non-logged-in user to upload. Then, I tried uploading the app to a non-local server. This server is part of a shared web hosting package and has cPanel. The app works fine till I upload the image and then it shows a 503 error. The server resource logs show that usage spikes when I upload the image and it is fed into the pre-trained neural network but nothing that would overpower the limits, only 75% of server physical memory being used. Server Specs: Server Specs TLDR: Uploaded a Django app with an Image Classification model which shows a 503 error after uploading the image from the front-end.

How to read file from DigitalOcean Spaces using Django?
I have a Django app that uses DigitalOcean Spaces to store user-uploaded files. The app then transcribes those files and returns the text. However when I try to read the file using the url to the stored file it fails.

How do I display an image slideshow using Bootstrap Carousel in Django?
I am trying to display a slideshow using Bootstrap Carousel in Django. The idea is to show multiple images in the slideshow for each event detail (attached with a foreign key).

Why uwsgi doesn't disable threads inside django application
Uwsgi docs says, that threads inside an application are turned off until you haven't explicitly turned them on. For me, it works not like that. I have checked it through a simple view in django. uwsgi run params: - uwsgi - --socket=0.0.0.0:8081 - --module=conf.shop.wsgi - --buffer-size=65535 - --py-autoreload=1 - --lazy - --lazy-apps - --vacuum When uwsgi starts, it writes: *** Python threads support is disabled. You can enable it with --enable-threads *** View code: from threading import Thread def view(): def foo(time_sleep, number: int): time.sleep(time_sleep) return number results = {} threads = [] for i in range(8): thread = Thread( target=foo, kwargs={'time_sleep': 1, 'number': i}, name=f'task {i}', ) threads.append(thread) [thread.start() for thread in threads] [thread.join() for thread in threads] performed_threads = [thread for thread in threads if thread.result is not None] for thread in performed_threads: results[thread.name] = thread.result return results But this code works for 1s, not 8s. I tried --strict and many other options, but didn't find why it works in that way. How to turn them off, if it is possible? -

Is it necessary to use Nuxt Server as an intermediary between my external Django API and the Nuxt 3 frontend in SSR mode?
I am developing a SaaS application using a backend architecture with a Django REST API and a PostgreSQL database, while the frontend uses Nuxt 3 with TypeScript, Tailwind, and TanStack Query for API request management. I have enabled Server-Side Rendering (SSR) by setting ssr: true in the nuxt.config.ts file : export default defineNuxtConfig({ ssr: true, }) In my current architecture, I have a server/api/ directory within my Nuxt 3 application containing multiple files that represent endpoints to interact with the Django API. For instance, I have a file server/api/projects/index.ts that points to the Django endpoint /api/projects/ to fetch all projects. Nuxt Server Integration: Nuxt Server Directory Structure: server/api/projects/index.ts : Points to the Django endpoint /api/projects/ to fetch all projects. server/api/projects/[id].get.ts : Fetches a project by its ID from /api/projects/detail/${projectId}/. API Interaction Logic: These endpoints are used within a service handler (api/projects.api.ts) that provides functions like getAllProjects, getProjectById, and deleteProjectById. Composable (useProjects.ts): The composable useProjects.ts uses the functions in api/projects.api.ts to manage project data and interact with the Nuxt Server endpoints in server/api/projects/. It leverages useQuery from TanStack Query for efficient state management. Question : Is it necessary to have an intermediary Nuxt server between the Nuxt 3 frontend and an … -
Poetry installed packages not recognized in VS code
I need some advice on Poetry package manager. I am working on a Django rest API. I use Poetry for the project. I ran into a situation that I do not understand. First, I made a virtual environment with pyenv, then I ran poetry install to install required packages, such as Django restframework, psycopg2 and everything. After that, in the VScode, it doesn't seem these packages not working properly because when I import these packages, it shows yellow underline. When I installed these packages globally with pip, then it all started working. So, my question is that when I work with Poetry, should I install the all packages that I need in a project globally also? It seems a little bit messy. Please give me an advice or any comment will be greatly appreciated. -
HttpOnly cookie in NextJS + Redux + Django API for storing JWT
I'm using NextJS in the frontend, Django API in the backend along with DRF and JWT for authentication and redux for state management. Almost all of my routes requires authentication. I'm able to store and access tokens in http-only cookies via NextJS routes API but since I'm using Redux too, all of my requests are going like this; user request -> redux action -> nextjs route -> backend Is this normal? I'd to implement nextjs route for each route just to access the http-only cookie and send it to backend endpoint as the route requires an authentication. This is tedious to implement and maintain, I've hundreds of routes. Is there any other way I can achieve this efficiently? -
