Usage

Registering Periodic Tasks

There are three supported ways to register periodic tasks:

1. In a tasks.py file in a Django app, using the @register_task decorator:

   # tasks.py
   from django.core.mail import send_mail
   from django_q.models import Schedule
   from django_q_registry import register_task
   
   
   @register_task(
       name="Send periodic test email",
       schedule_type=Schedule.CRON,
       # https://crontab.guru/#*/5_*_*_*_*
       cron="*/5 * * * *",
   )
   def send_test_email():
       send_mail(
           subject="Test email",
           message="This is a test email.",
           from_email="[e-mail]",
           recipient_list=["[e-mail]"],
       )
   

2. In a tasks.py file in a Django app, using the registry.register function directly:

   # tasks.py
   from django.core.mail import send_mail
   from django_q.models import Schedule
   from django_q_registry.registry import registry
   
   
   registry.register(
       send_mail,
       name="Send periodic test email",
       kwargs={
           "subject": "Test email",
           "message": "This is a test email.",
           "from_email": "[e-mail]",
           "recipient_list": ["[e-mail]"],
       },
       schedule_type=Schedule.CRON,
       # https://crontab.guru/#*/5_*_*_*_*
       cron="*/5 * * * *",
   )
   

3. In a Django project's settings.py file, using the Q_REGISTRY["TASKS"] setting:

   # settings.py
   from django_q.models import Schedule
   
   
   Q_REGISTRY = {
       "TASKS": [
           {
               "name": "Send periodic test email",
               "func": "django.core.mail.send_mail",
               "kwargs": {
                   "subject": "Test email",
                   "message": "This is a test email.",
                   "from_email": "[e-mail]",
                   "recipient_list": ["[e-mail]"],
               },
               "schedule_type": Schedule.CRON,
               # https://crontab.guru/#*/5_*_*_*_*
               "cron": "*/5 * * * *",
           },
       ],
   }
   

Setting up Periodic Tasks in Production

At some point in your project's deployment process, run the setup_periodic_tasks management command:

python manage.py migrate
python manage.py setup_periodic_tasks

This command automatically registers periodic tasks from tasks.py files in Django apps, and from the Q_REGISTRY["TASKS"] setting. It also cleans up any periodic tasks that are no longer registered.
