go-crontab | 分布式任务调度系统 | Cron Utils library

When running pip install django-cron I get the following error:

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:

1. Make a crontab that runs every minute
2. Every minute, check if there are any emails that need to be sent
3. Send out those emails

This feels a bit hacky and over-engineered. Is there a better way? Thanks!

I have a Django application which I want to configure it celery to run background tasks.

Packages:

1. celery==4.2.1

2. Django==2.1.3

3. Python==3.5

4. Redis-server==3.0.6

Configuration of celery in settings.py file is:

I have few cronjobs running with the help of django-crontab. Let us take one cronjob as an example, suppose this job A is scheduled to run every two minutes.

I have a Django based web application, some functionality of the application is scheduled to be run as a part of cron jobs using django-crontab. I want to hook a debugger so that I can inspect some odd behaviours of my code. I normally use visual studio code. Is it possible to hook a debugger, since cron jobs basically run independently apart from server?

I have to allow the admin the set the cron time from admin view in django. Like i have an configuration model , where admin can put the time as record

1. 2 am (record 1)
2. 4 pm (record 2)

So on each record i have to run the cron. But cron time is in setting.py

I'm using django-crontabto run a function every day in my server. When I add the cron with python manage.py crontab add everything is ok, I can see the crons and they execute normally (I've tested them running every minute and they do what I want). The problem is the next day it always throws this error:

Sorry for my english. I use django-crontab in my project. Localy in my project work fine. But i want use Doker, when i run Docker i have error:
