Any python/django libraries that convert datetime and timedeltas to phrases like "tonight at 8pm" or "tomorrow evening"?
I'm looking for a python or django library to give me humanized timedates to read like "tomorrow evening at 8pm" or "tonight at 8pm" or "next Monday at 8pm". I've seen django.contrib.humanize and arrow but neither give that level of humanization. Does such a library exist?

Auto-submit django form without causing infinite loop
I have an issue on my app that I can't work out the best way to approach the solution. I'm learning Django and have little to no experience in Javascript so any help will be appreciated. This may be a design flaw, so am open to other ideas. Problem When a user reaches their dashboard page for the first time, they would need to select the currency rate on a form they want to view their data in e.g USD, AUD, GBP etc. Once they submit their currency, their dashboard will become active and viewable. I would like this selection to remain submitted on refresh/load or auto submit on refresh/load. Hence, that currency will remain, unless the user submits another currency. See before/after images for context (ignore values as they are inaccurate): Attempted solution I have tried using Javascript to auto submit on load which causes and infinite loop. I have read to use action to redirect to another page but i need it to stay on the same page. Unless this can be configured to only submit once after refresh/load I don't think this will work <script type="text/javascript"> $(document).ready(function() { window.document.forms['currency_choice'].submit(); }); </script> <div class="container"> <div> <span> <h1>My Dashboard</h1> … -
Django QuerySet exists() returns True for empty set?
Something curious I found recently is that exists() evaluates to True for an empty QuerySet: In [1]: MyModel.objects.all() Out [1]: <QuerySet []> In [2]: MyModel.objects.all().exists() Out [2]: True When used with filter(), I get the expected result: In [3]: MyModel.objects.filter(id=1).exists() Out [3]: False This is behaving contrary to how I would expect as the empty QuerySet returned by the filter() is equivalent to MyModel.objects.all() which is empty. Why does this happen? It seems inconsistent. -

Django: How to run a celery task only on start up?
I have a django app that uses celery to run tasks. Sometimes, I have a "hard shutdown" and a bunch of models aren't cleaned up. I created a task called clean_up that I want to run on start up. Here is the tasks.py from my_app.core import utils from celery import shared_task @shared_task def clean_up(): f_name = clean_up.__name__ utils.clean_up() Here is what celery.py looks like: import os from celery import Celery from celery.schedules import crontab from datetime import timedelta os.environ.setdefault("DJANGO_SETTINGS_MODULE", "my_app.settings") app = Celery("proj") app.config_from_object("django.conf:settings", namespace="CELERY") # Load task modules from all registered Django apps. app.autodiscover_tasks() app.conf.beat_schedule = { "runs-on-startup": { "task": "my_app.core.tasks.clean_up", "schedule": timedelta(days=1000), }, } @app.task(bind=True) def debug_task(self): print(f"Request: {self.request!r}") How can I change celery.py to run clean_up only on start up? Extra info: this is in a docker compose, so by "hard shutdown" I mean docker compose down By "on start up" I mean docker compose up
