Tryton provides a scheduler (aka cron) which can execute methods of models periodically at set intervals.
The planning is managed by
ir.cron records which store the method to call
and the interval of time between calls. The method must be a class method of a
Model which can be called without any parameters.
To register a new method with the scheduler, you must extend the
model and append the new method to the
selection attribute of the
__setup__(). The name of the selection
must be the model name and the method name joined together with a
from trytond.model import Model from trytond.pool import PoolMeta class Cron(metaclass=PoolMeta): __name__ = 'ir.cron' @classmethod def __setup__(cls): super().__setup__() cls.method.selection.append( ('my_model|my_method', "Run my method"), ) class MyModel(Model): "My Model" __name__ = 'my_model' @classmethod def my_method(cls): pass
