Write cron business logic as a Python class and let this app do the rest! It enables Django projects to schedule cron tasks, tracks their success / failures, manages contention (via a cache) etc. Basically takes care of all the boring work for you :-)

QUESTION
I'm building a web app where I have a calendar where users can choose a day and an hour in the future and schedule tasks. The scheduled task is a simple function in python to be called on the exact date and time the user has chosen to.
I came across the schedule package but I rapidly understood that it wasn't suitable for my goal as they explicitly stated that it shouldn't be used if you need job persistence and localization, which I definitely need.
Because of my need, I think I'll need to use some sort of OS cron such as the crontab on Linux. The issue is that I do not need to have my function execute every given time interval but only at a given time chosen by the user.
Is there any other solution than crontab? I've seen the python-crontab package but it seems able to execute commands and not really function directly on a Python file.
Any thoughts?
PS I'm using Django and I've already seen the django-crontab package but it seems too static to me as I need to have dynamic cron jobs to add/remove

ANSWER
Answered 2021-Nov-01 at 23:54A Docker container only runs one process. You need to run two separate things: the main application server, and (after some initial setup) the cron daemon. You can straightforwardly run two separate containers running two separate commands from the same image, with the correct setup.
The first change I would make here is to combine what you currently have as a split ENTRYPOINT and CMD into a single CMD:

QUESTION
I'm facing a very strange error from few days now. I have a python2.7 project that was running smoothly but since few days its been throwing an error:
Process finished with exit code 134 (interrupted by signal 6: SIGABRT)
I'm using virtual environment for my project. What happened was that few days ago I tried installing nginx using brew command and what I believe is brew updated some dependencies that were being used for python2.7 project (this is what i think might be the case). Now since that day, I'm facing this issue and I have googled it everywhere but couldn't resolve. Below is some information you might need to figure out.

QUESTION
I am working on a web app in Django and I need to send some random numbers to the database every day at 8am.
I have tried to use celery but it has not worked. I am using windows and from a tutorial I understand celery does not work on windows.
I have tried using django-extensions and django-cron but it needs changes made to the linux cron and as I said before, I am on windows.
How should I solve this? Any help would be appreciated.
...ANSWER
Answered 2020-Oct-06 at 12:15I was in your current situation about a year ago. I was looking around for a background scheduled task solution for Django on Windows but it seems nothing stands out.
Have a look into these:
- [Django Background Task] (https://django-background-tasks.readthedocs.io/en/latest/)
- Django Dramatiq
Or simply, just use Windows Task Scheduler to execute python script, however, the two packages above help you to execute long running task on demand from Django, or set schedule from Django as well.

Answered 2020-Aug-17 at 08:51This usually happens when you don't have write access to your /vagrant/.venv folder. You can check access with ls -l cmd.
If so, you should change your access on your /vagrant/.venv folder.
QUESTION
I want to mimic the functionality that Gmail has, where you can choose to send an email at a certain time (maybe 3:34 am tomorrow) in Django.
I looked at something like django-crontab (https://pypi.org/project/django-crontab/).
I came up with an idea to use django-crontab to achieve this:
- Make a crontab that runs every minute
- Every minute, check if there are any emails that need to be sent
- Send out those emails
This feels a bit hacky and over-engineered. Is there a better way? Thanks!

Answered 2020-Aug-23 at 21:53You can check out celery and how to integrate it with django. Once done, task scheduling is easy,first add your gmail configuration in settings.py as follows:

Install django-cron
You can use django-cron like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
