Im trying to create a simple application (to create a graphql api using django and python). It's going well but im stuck with 1 problem and i have no idea how to go about it (ive been searching for days, but i simply give up) so i was hoping someone here could assist (see below what i have). Im using Django with graphene-django and neo4j as (graph)database. Also im using the relay schema.

How to increase expiry date/time of Google Cloud Storage Objects in Django
I have a Django REST API that uses the storages.backends.gcloud.GoogleCloudStorage as its DEFAULT_FILE_STORAGE. I noticed that media files (e.g. profile pictures of users) retrieved from any API has an Expires value in the URL. Here's a sample URL to a file: https://storage.googleapis.com/<BUCKET_NAME>/users/a96db2f0-99a0-4691-aadb-708dc5268f77.png?Expires=1597840065&GoogleAccessId=<ACCESS_ID>&Signature=<SIGNATURE> If I convert that to an actual date, it's actually 24 hours from the time it was requested. How do I increase that to a very big time (e.g. 1 year)? -

Celery scheduling performance with Django and multi-tenancy
I am working on a project and am looking for the best way to implement the following: our customers need to be able to specify an action that happens anywhere in the future. They also need to be able to cancel it (before it runs). It is a large task so it needs to be asynchronous. The frequency of this happening would be once every few days at most. I made a periodic task that looks at the database every hour if there are upcoming actions we need to perform in the next 2 hours (1 hour overlap). If an action is found I call apply_async and specify an ETA to schedule a task. I don't do it once daily because we use Redis and Redis cannot handle task scheduling further than 12 hours in advance because of the visibility timeout. The problem I see with this approach is that it's a bit complex and I need to implement a way to cancel an already scheduled task (revoke). Handling crashed wouldn't be such a big problem since the tasks are persistent. An alternative is to just run a periodic task every minute that immediately schedules a task (just in time). … -
celery task calls another microservice api - authentication
I have a Django system that contains several microservice projects. I'm using djangorestframework-sso for authentication between them. In one of my microservices I have a celery task that calls an api function from another microservice. The call fails because the authentication headers are not provided. I tried using the celery task to inject the wanted headers but it didn't help: class MyTask(Task): abstract = True def apply_async(self, args=None, kwargs=None, task_id=None, producer=None, link=None, link_error=None, **options): """ invoked either directly or via .delay() to fork a task from the main process """ token = 'XXX' options['headers'] = options.get('headers', {}) options['headers'].update({ 'Authorization': 'Bearer ' + token, }) return super(MyTask, self).apply_async( args, kwargs, task_id, producer, link, link_error, **options) The requests are made using python's requests library. So I thought trying to catch all requests and inject the headers before they are executed. Don't know how to do that. Any help will be appreciated. -
How to properly test my consumer class, so a user can log in, using selenium, pytest-asyncio and pytest-django?
I want to test my consumer class. So I have followed Django Channels doc on testing consumers. I have installed pytest-django and pytest-asyncio. But I need to log in before I connect to the site. So I am trying to use selenium and Django client to login and put the cookie in the headers of the consumer. But I am missing something because django.core.exceptions.SynchronousOnlyOperation is raised. I am using database_sync_to_async when I am creating user with FactoryBoy in a fixture. In my test function I am trying to use the database_sync_to_async marker before calling client.login. But that raises the error. When I mark the function with database_sync_to_async instead pytest does not collect my test. And when I logged in and tried to add the cookie to selenium in the fixture and then put it in the header in the test function I get keyerror: sessionid. (The outcommented code). So how to properly test my consumer class, so a user can log in? My code is the following: 1 import pytest 2 from channels.db import database_sync_to_async 3 from asgiref.sync import sync_to_async 4 from channels.testing import WebsocketCommunicator 5 from django.test import Client 6 7 from selenium.webdriver.firefox.webdriver import WebDriver 8 from selenium.webdriver.support.wait import … -

How to create a log database in django to record the user that created, updated or deleted an object?
I'm facing a difficulty recording the user in database who created, updated or deleted an object.
