![]() ![]() ![]() To add a cron job class to the list in Admin we need to set ALLOWED_CRON_TASKS setting: ALLOWED_CRON_TASKS = ( 'HelloWorld', ) Some cron jobs can be requested to start from Admin area: Admin > Cron > Cron Tasks Run single cron jobĬommand cron_worker run is responsible for executing cron jobs: python manage.py cron_worker run HelloWorldĬron job classes can accept parameters which are passed to run method as positional or named arguments: class HelloWorld ( BaseCronJob ): """Demo Cron Job class""" def run ( self, what, sleep = None ): """Main logic""" print "Hello -c "python manage.py cron_worker run Foo:bar=1" Cron Tasks - running cron jobs from Admin area This command should be added to system's crontab on server responsible for running periodic tasksĪnd executed every 2 minutes. This command constructs a list of jobs that should be executed in current period (now +/- 1 minute)Īnd creates a new subprocess for each job. For example: # settings_local.py CRONMAN_JOBS_MODULE = 'app.cron_jobs.name' Run the schedulerĬron jobs defined in settings.CRONMAN_JOBS_MODULE are started by cron_scheduler command from cron app. ![]() Remember, this module MUST have a CRON_JOBS attribute. Set CRONMAN_JOBS_MODULE to the dotted path name of the module where cron jobs are specified. # (, ) # 'HelloWorld' will be executed a 5:15AM every day: ( ' 15 5 * * *', 'HelloWorld' ), ) To ensure that a cron job is executed periodically, you have add an entry to CRON_JOBS: CRON_JOBS = (. If there is more than 1 cron job in given app, it's recommended to create a package instead of single cron_jobs module, create one submodule per class and do the imports and registration in package's _init_.py. It's also possible to retrieve or unregister a class (e.g. register ( HelloWorld )Ĭron job classes are registered (and referred to) by name, which may be customized on registration: cron_job_registry. To add a new job, you have to create cron_job.pyįile inside an app, create BaseCronJob subclass inside and register it: from cronman.job import BaseCronJob, cron_job_registry class HelloWorld ( BaseCronJob ): """Demo Cron Job class""" def run ( self ): """Main logic""" pass cron_job_registry. pip install django-cronman Define a new cron jobĬron job definition is inspired by Django Admin configuration. You can also install it with additional dependencies to be able to use Cron Remote Manager. Installationĭjango-cronman can be installed directly from PyPI using pip: pip install django-cronman Django app to define and manage periodic tasks at Python level. ![]()
