Stop Celery Job to get triggered at every deployment on AWS
I am usingCelery in Docker container deployed on AWS for some asynchronous jobs scheduling withRedis as the broker. Here is my config in settings.py. All is working well. My only issue is the the job is getting triggered at every deployment even though I have set specific times for it. Otherwise after the deployment it works fine. I am scratching my head to stop the first triggering. settings.py CELERY_BROKER_URL = "redis://localhost:6379" CELERY_RESULT_BACKEND = "redis://localhost:6379" CELERY_BEAT_SCHEDULE = { "fill_db_daily": { "task": "agendanotification.tasks.fill_db_daily", "schedule": crontab(hour=0, minute=1), }, "articles_email_daily": { "task": "agendanotification.tasks.articles_email_daily_prod", "schedule": crontab(hour=0, minute=30), } } In tasks.py: @shared_task def fill_db_daily(): call_command("fill_db", ) @shared_task def articles_email_daily_prod(): call_command("articles_email_prod", ) -
500 error when deploying Django app to Heroku with no obvious error messages
I am trying to deploy my Django app via Heroku and keep receiving a 500 error. I'm new to Django so am not really sure what could be going wrong as I've followed a tutorial online pretty closely, but I've obviously mucked something up somewhere. I've looked at the logs and it doesn't really tell me anything... at least nothing that I can decipher.

Authorization Headers is missing using c# client
I am developing a RESTFUL API using django-rest-framework. And for Authorization I choose to use Token Authorization (not JWT). Below is what I tried: Using POSTMAN (Works) headers: Authorization: Token 329367424fd30a876ccff05dbc5a18d86fe7158c Using C# Client (no working) HttpClient client = new HttpClient(); client.DefaultRequestHeaders.Add("Authorization", "Token 329367424fd30a876ccff05dbc5a18d86fe7158c"); await client.GetAsync(<url>) // Authentication credentials were not provided. After I debug and override TokenAuthentication function, I realize that Authorization headers is being removed if requested from C# Client. I saw a lot of question are being asked related to this problem, and the solution is adding WSGIPassAuthorization On I am not sure where should I add above line wsgi.py import os from django.core.wsgi import get_wsgi_application os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'nusames_core.settings') application = get_wsgi_application() FYI: I am planning to use gunicorn as my webserver, also I need it work locally (I am not using venv) Question: is there any workaround for my local env in order to make it works on c# client, and is there any best practice for production env? -

Payments on website: From customers to the website and vice versa
I am creating a website that needs to do this points: Receive payments to the Web site. I know that there are several payments gateways to do this. Can anyone recommend any? Make payments from the Web site to the people who are registered on the site. This people can live in any country and so they can have accounts in any bank of the world. It's possible to make bank transfers to any bank? There's another way to do it, for example with PayPal? If anyone has another idea how to do this I would be very grateful if you tell me. Without having this resolved I cannot move forward on my website. My Web site uses: HTML, CSS, Bootstrap, Jquery, Django y Python, with a SQLLite database. Thanks. -
How can i run a Django app and a Vue on the same port?
I'm building a SPA using Django for my backend and Vue to handle the entire frontend. In order to avoid some security issue and keep using the standard Django's session authentication, i'm going to run these two apps in production on the same sever and on the same port, and i will setup Nginx to route traffic, so that /account/login will be handled by Django, while /app/someURL is redirected to the Vue application. My question is: how can i do the same locally, during development? If i run manage.py runserver and npm run serve -- ---port 8000 the two apps will clash because there is no way to know where should each request be redirected. -

Why is django-cleanup deleting used media files?
I have django-cleanup installed on my project, and I've ran into a bug where anytime I upload an image with the same name as another image already in the media folder, the old image is deleted and the new image is saved, but with new string on the end of it. This means I am losing used images when an image of the same name is uploaded. For example if I have image.jpg and I upload another image called image.jpg, the original image.jpg is deleted and the new one is saved as something like image_tccwtVY.jpg. I've implemented this in previous projects the exact same way (and version) and never had an issue. Can anyone think as to why it is doing this? -

I put the same secret key for all my domains . e.g. Let's Assume this is my secret key in django SECRET_KEY = "ehs-345asf4512*$^&__SH-35asdf43" i set this secret key in settings.py for http://127.0.0.1:8000/ I also set this secret_key in settings.py for http://127.0.0.1:8002/ I also set this same secret_key in settings.py for http://127.0.0.1:8003/ Then i was able to access Logged in/Out user from my http://127.0.0.1:8000/ project to another projects MY Question is that what happens if i put same SECRET_KEY for all my sub-domains on this domain? Is there any other way to get logged in/out user from my project. i am gonna work on android … -
How can I connect my pre-existing python script to Django
I am currently working on an Automated Machine Learning App, and my pipelines are implemented in python. Now that I need to move to the platform in Django, I'm finding difficulties to use my preexisting functions for the requests. (I am still very new to Django and was only able to configure the template which is the main page) I read about its MTV architecture and do understand the logic. My ML pipelines are currently called through my 'main.py' file and I need to shift this to the web app. -
How to turn off logging for SqlAlchemy db pool only, when debugging is enabled in Python Django?
Context / environment I have a Python Django project connecting to a PostgreSQL database with a SqlAlchemy django-postgrespool2 db pool. What I'm trying to achieve In settings.py I have set DEBUG = True which will make the program log. However, I want to disable the logging coming from the SqlAlchemy db pool only, while having DEBUG set to True. In other words, when debugging, I want to see all logs except for the ones coming from the SqlAlchemy db pool. What I've tested The code below shows too different attempts I've made to disable the db pool logging: def turnOffLog(self): # --- Attempt 1, db pool logs still show --- logging.basicConfig() logging.getLogger('sqlalchemy').setLevel(logging.ERROR) # --- Attempt 2, db pool logs still show --- sqla_logger = logging.getLogger('sqlalchemy.engine.base.Engine') for hdlr in sqla_logger.handlers: sqla_logger.removeHandler(hdlr) I also pass echo=False to the QueuePool instance when I create it, which still doesn't remove the logs: dbPool = pool.QueuePool(dbConnection, max_overflow=dbConfig.poolMaxOverflow, pool_size=dbConfig.poolSize, recycle=dbConfig.poolRecycleTime, pre_ping=dbConfig.prePing, dialect=postgresql.dialect(), echo=False) My settings.py file (DEBUG is set to True from an env-config file): """ Mbrain """ import os import logging import socket import sys from decouple import Config, RepositoryEnv import time # Build paths inside the project like this: os.path.join(BASE_DIR, ...) BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__))) … -

How to reject login when user already has a session in django
In my django application I want to reject a user login if he has already an active session. How can I do that? I tried some attempts using user_logged_in signals. Should I do this check login form with confirm_login_allowed() before new session creation? My current setup is like that: accounts/signals.py @receiver(user_logged_in) def check_existing_session(sender, user, request, **kwargs): session_key = request.session.session_key user.set_session_key(session_key) accounts/models.py def set_session_key(self, key): self.last_session_key = key self.save() -
Enable Partial/Free/Full text search on a unique column PostgreSQL
I have a unique column inside the table of type citext (at Django model level CICharField). colName = CICharField(max_length=255, unique=True) This column has a unique constraint(index) enabled. UNIQUE CONSTRAINT, btree (colName). I have a case where I want to perform a partial/full/free text search on this column using %LIKE%. Now since this already has a unique constraint index enabled on this column, is there a way to create another index that can be used by %LIKE% query to improve the performance? I understand that only 1 index can be used at once but I was just wondering if there is any workaround to improve this a little more. I'm using Django ORM, which provides __contains attribute, that can be used to perform %LIKE% queries. Since it's a citext type column, I can't use the search attribute provided by Django. https://docs.djangoproject.com/en/3.1/ref/contrib/postgres/search/ I guess adding db_index=True wouldn't help either.
