How to add a task from a celery task to the main process loop:django
I want to add a task to the asyncio loop of the main process from celery that runs periodically. I've looked into this to the point where it might be feasible with multiprocessing. However, in the end it looked like I would need to check periodically in the main process to see if the task was added. Is it possible to directly add a task from another process to the main process loop? loop.py import asyncio LOOP = None def run_loop(): global LOOP LOOP = asyncio.new_event_loop() LOOP.run_forever() init.py from celery import app as celery_app from project import loop import threading __all__ = ('celery_app',) threading.Thread(target=loop.run_loop).start() tasks.py from celery import shared_task from project.celery import app from app1 import task @shared_task def add_task(): asyncio.run_coroutine_threadsafe(task.task1(), loop.LOOP) app1/task.py import time def task1(): time.sleep(1) print("abcd") -

Best way to do user authentication with Django backend and React frontend?
I know this is a really general question but I really wanted advice on how to approach this. I have a Django backend running on AWS Elastic Beanstalk and a React frontend. I want to implement user authentication but I'm not sure on how to approach it. Should I do Django default user authentication by creating models and etc? Or should I instead use something else through the React frontend and JWT? I'm new to this and wanted to make sure what is the best approach for this. Thank you so much -
Entering URL in browser causes Python Django ReverseMatchError to be thrown
I am working on a python project while following a book to create an online shop website, I have created the models, views and urls for the app named 'Shop' the project overall is called 'My shop'. Whenever I try to type in the 'product list' url I am returned with the following error: Reverse for 'product_list_by_category' with arguments '(3, 'accessories')' not found. The expected result is the list.html page to be shown which includes all products because no category has been chosen in the URL. I have followed the code in the book exactly and have tried it multiple times yet the error still appears.

Docker behaves differently per server
Local environment: Arch linux Server a (digitalocean): Ubuntu latest Server b (digitalocean): Docker Ubuntu latest (one click app) My Django project which is running in a container can't run well only on the Server a.

How should I upload a Django project to GitHub?
This is probably a very dumb question. But I have a little project in Django and I would like to upload it to GitHub to just have it there. I know how GitHub works and I know how to upload the project. But I'm wondering if just uploading the whole folder is the right way to do it. I mean. I have a data base with my project, that has some information. So is the database JUST in my computer right? It won't get uploaded next to the project to github? So basically I'm asking: Should I just simply upload the whole folder? And if I were to download my project from GitHub from another computer. Should I just have to run migrations to make it work locally? -

What is the best way to integrate a react and django application?

Celery how to create a task group in a for loop

Django i18n using translation.activate
I have configured Django i18n and it works just fine if you change the browser language using the browser configuration UI. I have tested both English and Spanish. However, when I try to let the user pick the language from the navigation bar and set a new LANGUAGE_SESSION_KEY based on the selection made by the user it would not work. The browser language will continue to be the selected language instead. Here follows my code: MIDDLEWARE = [ 'django.middleware.security.SecurityMiddleware', 'django.contrib.sessions.middleware.SessionMiddleware', 'django.middleware.locale.LocaleMiddleware', 'django.middleware.common.CommonMiddleware', 'django.middleware.csrf.CsrfViewMiddleware', ... LANGUAGE_CODE = 'en' LANGUAGE_SESSION_KEY = 'en' TIME_ZONE = 'America/Sao_Paulo' USE_I18N = True USE_L10N = True USE_TZ = True LOCALE_PATHS = ( os.path.join(BASE_DIR, 'locale'), ) LANGUAGES = ( ('en', _('English')), ('es', _('Spanish')), ('pt', _('Portuguese')) ) The view that is triggered by the navbar: def setLanguage(request, language_code): language = get_language() try: request.session[LANGUAGE_SESSION_KEY] = language_code translation.activate(language_code) request.LANGUAGE_CODE = translation.get_language() request.session[translation.LANGUAGE_SESSION_KEY] = language_code request.session.save() except Exception as e: print("$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$ Oops!", e.__class__, "occurred.") translation.activate(language) return redirect('home_index') I have debugged that the language_code passed corresponds correctly to the selected language (e.g. es instead of en) but it is not activated. The browser language remains as the active language. I would appreciate any ideas. Thanks! Alberto -

Is it possible to check if a function has a decorator from a class attribute in DRF and Django?
I'm currently thinking of how to implement permissions in my Django application using DRF. My idea is to have several generic classes that inherit BasePermission and to define those classes in the view, ex: class ExampleView(ModelViewSet): permission_classes = (ExamplePermissionClass,) However, this might not suffice for some views that I have i.e. I might declare a generic class on the whole view but I might also want one @action to use different permissions. For this, I though of making decorator permissions which would check permissions on a per method basis. However, I do think that permission_classes are executed first and this won't work. Is there a way arround this? Example: class ExampleView(ModelViewSet): permission_classes = (ExamplePermissionClass,) @permissions(PermissionName etc...) @action(...) def example_action How can I circumvent the permission class and only check the decorator here? -

How to connect jupyter-lab in my Django project to the Django's models?
I am a bit new to Django and was wondering on how to do this. I have a jupyter-lab called forecasting.ipynb in the same folder as my manage.py and db.sqlite3. I want to connect to the db.sqlite3 to access the models that are in my models.py. I have a model called Coin. I want to basically be able to do Coin.objects.all() and access all my coins but I'm a bit confused on how to do this. In my jupyter-lab file I have this: forecasting.ipynb import sqlite3 connection = sqlite3.connect('db.sqlite3') for row in cur.execute('SELECT * FROM Coin;'): print(row) connection.close() I tried this but it says 'OperationalError: no such table: Coin'. I also tried both coin and COIN as well but both didn't work. I'm really confused because I have a model called Coin in my models.py. models.py from django.db import models class Coin(models.Model): ticker = models.CharField(primary_key=True,max_length=10, unique=True) baseVolume = models.BigIntegerField(default=0) coin_name = models.CharField(default="", max_length=50) coin_description = models.TextField(default="") # price = models.FloatField() def __str__(self): return "{}-{}".format(self.ticker,self.baseVolume) And when I do Coin.objects.all() in my tasks.py, it works perfectly. Is my syntax/code wrong or am I misinterpreting something? Thank you so much! -
Django: Corresponding values to String options
Let's say, I have a hotel booking form and I want to have 'room types' with different prices. Then after selecting a room type, I add its corresponding price to the Total Price. So my questions are: How do I make such option list with corresponding prices, where I can use the price and add it to the total? (maybe through javascript). Right now, I have the models & forms set up, and the javascript code for adding the other option (one being an input field for no. of nights, and another being a checkbox for including breakfast). I was thinking of using a list of tuples, but I don't particularly know how to implement it. -
